Usage
As a food additive, sodium lactate has the E number E325 and is naturally a liquid product, but also is available in powder form. It acts as a preservative, acidity regulator, and bulking agent.[5]
Sodium lactate is sometimes used in shampoo products and other similar items such as liquid soaps, as it is an effective humectant and moisturizer.[6]
Sodium lactate is used to treat arrhythmias caused by overdosing of class I antiarrythmics, as well as pressor sympathomimetics which can cause hypertension.[7]
It also can be given intravenously as a source of bicarbonate for preventing or controlling mild to moderate metabolic acidosis in patients with restricted oral intake (for sodium bicarbonate) whose oxidative processes are not seriously impaired. However, the use in lactic acidosis is contraindicated.[8] It can cause panic attacks in patients with existing panic disorder.[9]
It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system.[10]
Regarding milk
Despite the similarity in name, sodium lactate is not chemically similar to lactose (milk sugar), so need not be restricted by those with lactose intolerance.[4][11] In general, lactates such as sodium, calcium, and potassium lactate are salts derived from the neutralization of lactic acid and most commercially used lactic acids are fermented from dairy-free products such as cornstarch, potatoes, or molasses.[12] Sugar or tapioca additionally may be used. In some rare instances, some lactic acid is fermented from dairy products such as whey[4] and lactose.[12] Whey is made of up 6.5% solids of which 4.8% is solid lactose.[13] Waste whey is infrequently used to produce lactic acid when the whey itself is produced as waste during the manufacture of certain dairy products.[14] Such dairy-type lactic acid generally goes back into dairy products, such as ice cream and cream cheese,[12] rather than into nondairy products. Moreover, although the lactic-acid starter culture to ferment corn or beets may contain milk,[4] sodium lactate does not contain milk protein and need not be restricted by someone avoiding milk or those with a milk allergy.[4][11]
Sodium Lactate is a sodium salt of racemic or inactive lactic acid with alkalinizing and electrolyte replenishing property. Upon metabolism, sodium lactate is converted to bicarbonate, thereby increasing plasma bicarbonate, which facilitates removal of hydrogen ion and lactate from blood stream and leads to raised blood pH.
Sodium lactate is an organic sodium salt having lactate as the counterion. It has a role as a food preservative and a food acidity regulator. It is an organic sodium salt and a lactate salt. It contains a lactate.

Sodium lactate, also known as mediject L or E325, belongs to the class of organic compounds known as carboxylic acid salts. These are ionic derivatives of carboxylic acid. Sodium lactate is an extremely weak basic (essentially neutral) compound (based on its pKa). Sodium lactate is an odorless tasting compound.
What is it?
Sodium lactate is the sodium salt of lactic acid, and has a mild saline taste.
What does it do?
It is often used as a preservative or pH buffer in foods but has moisturizing properties that make it useful in gentle cleansers and creams. We use it in our bodywash to provide gentle cleansing and aid in preservation.
How is it made?
Sodium lactate is most often made by the fermentation of a sugar, which can come from corn or beets, to produce lactic acid. Tom’ uses a sodium lactate derived from corn. The fermentation product, lactic acid, is neutralized to create sodium lactate.
Although it can be prepared by fermentation of milk or whey protein, that is not often the case and the resultant fermentation product will not contain any residual milk protein.1
Is this the right option for me?
Sodium lactate should not be confused with dairy or lactose. It is not chemically similar and is safe for those individuals looking to avoid lactose.
Sodium Lactate is considered a GRAS food additive by FDA.

Sodium Lactate is found naturally in the stratum corneum of human skin. When manufactured, it is most often produced through the fermentation of a source of sugar — for example, beets or corn. The compound is subsequently derived by neutralizing the isolated lactic acid that results from the fermentation process.
Sodium lactate is primarily indicated as a source of bicarbonate for prevention or control of mild to moderate metabolic acidosis in patients with restricted oral intake whose oxidative processes are not seriously impaired. Sodium Lactate is most commonly associated with an E number of “E325” Sodium Lactate blends are commonly used in meat and poultry products to extend shelf life and increase food safety. They have a broad antimicrobial action and are effective at inhibiting most spoilage and pathogenic bacteria. In addition sodium lactate is used in cosmetics as a humectant, providing moisture.
Sodium DL-lactate solution is for inclusion in standard lactated Ringer′s solution. It has been used as a component in Trypticase soy broth to culture P.
Sodium lactate has a cushioning effect to stabilize the pH of foods. It is also used in many foods as a seasoning to improve flavor. Sodium lactate has excellent moisture-retaining effects that are not affected by temperature and humidity, which helps retain moisture even at low temperature and low humidity.It is a colorless and clear syrupy liquid that is odorless or has a faint and unique odor.
Sodium lactate, from Jungbunzlauer, is the sodium salt of L(+)-lactic acid, obtained by neutralisation of the acid of natural origin with a high purity sodium source.
SODIUM LACTATE IS VEGAN
Although it is the salt of lactic acid, sodium lactate is quite a herbal product. Because the chemist Carl Wilhelm Scheele was able to detect lactic acid in milk for the first time in 1780, the name, which is now very misleading, came about.
Like other lactates, the ingredient is obtained through fermentation: microbial or enzymatic processes convert a source of sugar, such as corn or beets, into acid. This lactic acid is then neutralized. The sodium lactate is ready..
Food manufacturers use lactic acid salt, for example, to regulate acidity, retain moisture, melt cheese or give food a firm consistency. Because it is harmless in food, it can be used as an additive E323 without hesitation.
SODIUM LACTATE RETAINS MOISTURE
The NMF is made up of various substances. These include proteins, urea, lactic acid, sugar and inorganic ions such as potassium and magnesium ions, but also our sodium lactate.
A comparison betweendry winter skin and normally hydrated summer skin has shown that sodium lactate creates a connection: the content of this substance was lower in dry skin. If the skin lacks sodium lactate, it tends to become dry.
This is because: Sodium lactate is able to bind moisture. The active ingredient increases the water content of the skin and ensures that it remains soft and less wrinkled.
So Sodium Lactate is an important ingredient in anti-aging care.
SODIUM LACTATE STABILIZES THE PH VALUE
Care products for the skin should preferably have a pH value between 5 and 5.5 so that they do not attack the skin's own protective acid layer. The acid mantle is closely related to the NMF and ensures that the skin does not lose moisture and prevent itbad bacteria andfree radicals remains protected.
In care products, sodium lactate, together with lactic acid, regulates the pH value. This allows cosmetics to care for the skin instead of attacking it.
BONUS: SODIUM LACTATE HAS A KERATOLYTIC EFFECT
Some substances in cosmetic products help the skin to loosen and remove dead skin cells from the horny layer. The property of these active ingredients is keratolytic. Sodium Lactate possesses such as for exampleurea also this property and has a correspondingly scaling effect.
Sodium Lactate is not only an endogenous and absolutely harmless substance, it significantly supports the NMF and helps to hydrate the skin.
This makes sodium lactate an important element for good cosmetics and also perfectly suitable for certified natural cosmetics.
Cosmetics manufacturers can easily use it in products that stay on the skin as leave-on products or rinse-off products. You can find sodium lactate in lotions, creams, shampoos and all kinds of care products.
WHAT ARE SODIUM LACTATE
Sodium lactate INCI: Sodium Lactate is the salt of lactic acid. In cosmetics, the ingredient maintains moisture, stabilizes the pH value and helps remove dead horny cells.
Sodium lactate is hygroscopic. It is derived from natural L(+) lactic acid, a weak acid having a dissociation 86 constant of 1.389.10-4 at 22°C (pKa=3.857).Sodium lactate has a content of 59-61% (w/w) and a 87 stereochemical purity (L-isomer) of at least 95% (Houtsma 1996).

Sodium lactate, when added to fresh meat, will delay the development of sour and off-flavors and is reported to be a very prominent flavor enhancer with few negative effects. One explanation for sodium lactate delaying the development of off-flavor is that it acts as a radical scavenger. It will bind to free radicals in meat to prevent lipid oxidation. Lipid oxidation is closely correlated to myoglobin oxidation. As lipid oxidation decreases, myoglobin oxidation decreases as well (McClure 2009). Under the USDA Food Safety and Inspection Service, these lactates are not allowed as flavoring agents in concentrations of more than 2% (USDA FSIS 2005).
Sodium lactate has been shown to improve cook yields of meat products because its humectant properties contribute to water-holding capacities of meat products. The increased processing yield with sodium lactate could also be due to a combination of increased levels of sodium ions and the humectants properties of sodium lactate (McClure 2009).
The addition of sodium lactate has been shown to increase the meat pH to produce a darker colored lean, the cut of the meat containing the least fat. The darker color meat containing sodium lactate also has been shown to stabilize with storage. This stabilization of meat color with storage is most likely due to the higher pH that provides some protection against oxidation during meat storage. Myoglobin is the pigment that gives meat its red color. When myoglobin is oxidized, it turns brown in the “metmyoglobin” state. Contributing factors
for oxidation of myoglobin are pH, the amount of exposed light, microbial growth and time. At a higher pH, oxidation of myoglobin is not as rapid. As sodium lactate addition has been associated with increasing meat pH to increase water-holding capacity and reduce cook losses, the resulting meat is more tender (Miller 2010).
There are three proposed mechanisms by which sodium lactate can have an antimicrobial affect. The first is changing water activity (aw). The addition of sodium lactate lowers the water activity of the meat and there by slows microbial growth. The second mechanism occurs as sodium lactate passes through the cell membrane and lowers intracellular pH, and the third takes place as sodium lactate affects cellular metabolism by inhibiting ATP2 generation. The lactic acid portion of sodium lactate has antimicrobial properties, as it can be incorporated into the microbial cell. Lactic acid then interferes or slows down the normal metabolic process that generates energy in the cell. This metabolic process is called glycolysis. The sodium ion also has some antimicrobial effects (Miller 2010).
Sodium Lactate is the sodium salt of natural L (+) lactic acid made by the fermentation of sugar. It has antimicrobial properties and is pH neutral. This product is widely used as a natural preservative in many applications. Best if used within 24 months of the manufacture date.
What is Sodium Lactate?
Sodium Lactate is a naturally occurring humectant derived from the salt of Lactic Acid. Despite the similar name, Sodium Lactate and Lactic Acid have very different chemical formulas; however what they do have in common is their excellent humectant properties.
Sodium Lactate is a natural component that can be found within the upper layers of your skin and contributes to the skins Natural Moisturising Factor (NMF). The NMF helps to keep your skin hydrated, supple and smooth by maintaining hydration levels.
What does Sodium Lactate do?
Sodium Lactate is a superior humectant moisturiser with over twice the water holding ability than Glycerin. It replenishes moisture by attracting and retaining water within the skin, preventing it from becoming dehydrated, dry and flaky. Some studies have shown that using Sodium Lactate can increase the moisture content within the skin by a minimum of 84%.
Sodium Lactate also acts as a buffering agent which works by balancing the formulations pH levels to maintain healthy skin. The normal pH for your skin ranges from pH 4 to 6; when this is out of balance and too acidic or alkali, it can cause sensitivities and depletes the skin of its natural protectant barrier. The skins natural barrier is essential to maintain its daily functions, whilst preventing water from being lost, and protecting it from harmful pollutants.
Benefits of Sodium Lactate for your skin
Whilst Hyaluronic Acid still holds its place as the number one ingredient for moisturisation, Sodium Lactate follows closely behind. Its ability to attract water and prevent it from evaporating prevents and protects the skin from becoming dehydrated to help your skin look and feel soft, smooth and radiant with a healthy looking glow.
Intensely hydrates dry and dehydrated skin
Retains water to refine and nourish the complexion.
Prevents moisture loss
Brighten the complexion with a healthy, hydrated glow

Is Sodium Lactate right for my skin?
Sodium Lactate is suitable for all ages and skin types. It is particularly beneficial to those who have dry skin or dehydrated skin.
Sodium lactate is an inexpensive, soluble, food grade and fast acting substrate, which rapidly establishes reducing conditions to support the biodegradation of chlorinated solvents. Sodium lactate is readily bio-available and as such has a short lifetime follow injection. Sodium lactate is often combined with longer lasting substrates such as emulsified vegetable oil (EVO) to provide a jump start to the bacteria population while the EVO will provide carbon and hydrogen to support biodegradation of the chlorinated solvents over a longer period of time.
Lactic acid sodium salt produced naturally through the fermentation of sugars. Clear and viscous liquid, slight odor. Emulsions: used as a co-preservative. Soaps: used for hardening soaps faster, making them last longer and giving them a more glossy finish. Soluble in water and alcohol. It is a combination of 60% sodium lactate and 40% water.
INCI: Sodium lactate
Properties: Antioxidant, bacteriostatic agent (stabilizes bacterial levels), pH control agent, humectant.
The effects of sodium lactate in soaps
- On pigments and other dyes: lactate can pale the shades of pigments and micas used for coloring soaps. These effects are very light and generally imperceptible.
- In the molds: The temperature rises in the molds, but no signs of fragrance degradation or other consequences have been observed. Lactate helps demolding soaps made in individual molds.
- On hardness and cutting: soap hardens much faster with sodium lactate than without it. It is therefore recommended to demold and cut the soaps as soon as possible. Generally, the soaps are ready to be cut after 18 hours, unlike 24 hours or more without lactate.
- On the weight of soaps: soaps made with sodium lactate will lose less water and shrink less than a soap made without lactate.
- Feel and other effects: sodium lactate gives soap a silky effect and a soft feel in addition to giving it moisturizing properties. Note that no effect on the quantity or quality of the foam has been observed. Sodium lactate does not affect the pH of the soap.
- Trace: caution, sodium lactate quickly makes a thick paste. It is recommended for opaque soaps that do not need to be worked. It is not recommended for marbling techniques that require a more liquid paste.
A great additive in cosmetic formulations, as humectant and moisturizer, helping to strengthen the skin barrier. For bar soaps, it helps to produce a harder bar that lasts longer, have a better texture and it's easier to unmold and cut and reduces cracking.

Sodium Lactate is naturally derived from the fermentation of Lactic Acid. It is a clear colorless viscous liquid with a mild odor. Sodium Lactate is considered to have antioxidant properties and can improve bacterial stability with when used in combination with a full spectrum preservative. Please note that Sodium Lactate is not an effective preservative in itself but used in addition to a full spectrum preservative to improve bacterial stability (Bacteriostatic agent).
Sodium Lactate is also considered to be a natural humectant (draws moisture to itself) and is frequently used as a substitute for glycerin in lotions, creams, hair care products and cosmetics. When added to cold process soaps, it is said to harden the soap faster, add creaminess and extend its shelf life in the shower (does not melt easily). It is said to improve the appearance of the finished soap, and ease with un-molding a batch of soap.
Sodium Lactate is a combination of 60% Sodium Lactate and 40% Water.
Usage:
• Can be used in a wide variety of personal care formulations to improve skin and scalp moisturization, and lighten complexion.
• Soluble in water and alcohol.
• Acts as a Bacteriostatic agent when combined with a full spectrum preservative.
• Recommended use levels in a finished formulation is 1 - 3%.
• It is a pH control agent.
• Compounding procedures: May be added to water phase with heat to ensure proper incorporation.
Sodium lactate is the sodium salt of lactic acid and is already a favorite among soap makers. But did you know sodium lactate is a “natural moisturizing factor” component of skin? Its a natural humectant added to lotions and creams as a less sticky alternative to glycerin.
It has the ability to hold more water than glycerin, sorbitol, and sodium PCA. The only thing better at attracting water is hyaluronic acid.
According to online reports, the sodium of lactic acid have a higher level of inhibiting pathogen growth than the actual lactic acid itself, in food.
Sodium lactate is used to push off spoiling for as long as possible because it has the ability to extend the shelf life of meat and poultry! So imagine how good it would be to add this, along with your broad spectrum preservative, to help keep the creepy crawlers out of your DIY skin creams and lotions.
The sodium lactate I use is in liquid form which is its natural state.
Another thing being studied about sodium lactate is its ability to slightly lighten darker spots on the skin. Some companies are starting to add it to skin toning creams and lotions.
Description
Sodium lactate has antimicrobial and antioxidant effects. It is used as a food additive as a safe organic preservative for fish, sausage, etc. Sodium lactate is a naturally occurring humectant that is an extremely effective moisturizer. It could be used in cosmetics, such as aftershave lotion. Sodium lactate is also advocated in the treatment of bradyeardia and asystole associated with complete heart block.
Food additive
Sodium lactate need not be restricted by someone avoiding milk or those with a milk allergy.In general, lactates such as sodium, calcium, and potassium lactate are salts derived from the neutralization of lactic acid and most commercially used lactic acids are fermented from dairy - free products such as cornstarch, potatoes, or molasses. Sugar or tapioca additionally may be used. However some lactic acid is fermented from dairy products such as whey and lactose . Whey is made of up 6.5 % solids of which 4.8% is solid lactose . Waste whey typically is used to produce lactic acid when the whey itself is produced as waste during the manufacture of certain dairy products . As a result, such dairy-type lactic acid generally goes back into dairy products, such as ice cream and cream cheese, rather than into non - dairy products. Moreover, although the lacticacid starter culture to ferment corn or beets may contain milk, sodium lactate does not contain milk protein and need not be restricted by someone avoiding milk or those with a milk allergy.
Uses
As a food additive, sodium lactate has the E number E325 and is naturally a liquid product, but also is available in powder form. It acts as a preservative, acidity regulator, and bulking agent.
Sodium lactate is sometimes used in shampoo products and other similar items such as liquid soaps as it is an effective humectant and moisturizer.
Sodium lactate is used to treat arrhythmias caused by overdosing of class I antiarrythmics, as well as pressor sympathomimetics which can cause hypertension.
It also can be given intravenously as a source of bicarbonate for preventing or controlling mild to moderate metabolic acidosis in patients with restricted oral intake (for sodium bicarbonate) whose oxidative processes are not seriously impaired. However, the use in lactic acidosis is contraindicated.
