Myristyl lactate = Tetradecyl lactate

CAS NO:1323-03-1
EC NO:215-350-1

MYRISTYL LACTATE is classified as :
Emollient
Skin conditioning

With its emollient effects (softening) on the skin, it gives skin and hair luster. It is used as base agent in shampoos, lipsticks, and various creams.

Cetyl/myristyl lactate is a white, wax-like solid made from lactic acid and esters of cetyl/myristyl alcohols. It is used as a skin lubricant and emollient with excellent softening properties, which makes skin and hair soft to the touch. It reduces glare, stickiness, and other effects of oil while also helping to prevent drying from alcohols and protect skin and hair. It also helps promote skin absorption of pharmaceuticals.

Myristyl lactate is a white, wax-like solid made from ester compounds consisting of lactic acid and myristyl alcohol (tetradecanol), which is a 14-carbon alcohol.
Myristyl lactate is used as a skin lubricant and emollient with excellent softening properties, which makes skin and hair soft to the touch. It has a low melting point near that of human body temperature and gives skin and hair a silky feeling. Because of this effect, Myristyl lactateis widely used as a base agent in shampoos, lipsticks, and various creams.

Product description

Versatile emollient with good solubility in aqueous alcoholic and glycol solutions. Imparts velvety skin feel when used in topical formulations. Liquefies at skin surface temperature offering a perceived cooling effect. Required HLB value of 12 (70°C). Recommended topical usage levels of 1-10%.

Liquid emollient, ester of lactic acid, offers unique emolliency and moisturization properties. Derived from plant sources. It is suitable for use across skincare, particularly for moisturizers and dry skin preparations.

Myristyl Lactate: Myristyl Lactate is the ester produced by a catalyzed reaction of either natural or synthetic myristyl alcohol and lactic acid. The ester produced by the reaction is washed to remove any catalyst and unreacted lactic acid. The final product is further washed with alkali and neutralized.

Myristyl Lactate is a white to yellow liquid or soft solid.
Because a hydroxyl group is present, this ingredient is particularly soluble in
ethyl alcohol and isopropyl alcohol. It is dispersible in mineral oil and insoluble
in water and glycerine.")

Myristyl Lactate is highly comedogenic. It means that if this ingredient is present in any product, it is very likely to cause pimples on acne prone skin. Even if your skin does not break out easily, you need be careful with products containing this ingredient.
Myristyl Lactate is not known to be irritating to the skin. Skin irritants may cause acne even if they are not pore-clogging. This is because they irritate the skin causing it to produce more sebum which may result in acne.
Myristyl Lactate is mainly used as an emollient and skin conditioner in cosmetic products.
