Glycerol monostearate, commonly known as GMS, is a monoglyceride commonly used as an emulsifier in foods. It takes the form of a white, odorless, and sweet-tasting flaky powder that is hygroscopic. Chemically it is the glycerol ester of stearic acid.
Glyceryl Stearate, also referred to as Glyceryl Monostearate, is a fatty acid derived from vegetable oil, Soy Oil, or Palm Kernel Oil; however, it is also naturally occurring in the human body. This wax-like substance appears white or cream in color and is produced when Glycerin and Stearic Acid undergo esterification.

What Is Glyceryl Stearate?

Glyceryl Stearate SE is a "Self-Emulsifying" form of Glyceryl Stearate that also contains a small amount of sodium and or potassium stearate. Glycerol monostearate exists as three stereoisomers, the enantiomeric pair of 1-glycerol monostearate and 2-glycerol monostearate. Typically these are encountered as a mixture as many of their properties are similar.
Commercial material used in foods is produced industrially by a glycerolysis reaction between triglycerides and glycerol.
Glycerol monostearate occurs naturally in the body as a product of the breakdown of fats by pancreatic lipase. It is present at very low levels in certain seed oils.
Glyceryl Stearate is the natural glyceryl ester of glycerin and stearic acid. It offers excellent hydration and moisturization. It acts as a non-ionic opacifier, thickener, emollient and formulation stabilizer. It is used in skin care and body care applications.
A super common, waxy, white, solid stuff that helps water and oil to mix together, gives body to creams and leaves the skin feeling soft and smooth.
Chemically speaking, it is the attachment of a glycerin molecule to the fatty acid called stearic acid. It can be produced from most vegetable oils (in oils three fatty acid molecules are attached to glycerin instead of just one like here) in a pretty simple, "green" process that is similar to soap making. It's readily biodegradable.
Glyceryl stearate is formed through a reaction of glycerin with stearic acid, which is a fatty acid that comes from animal and vegetable fats and oils. Glyceryl stearate SE, the self-emulsifying form of the substance, is made by reacting an excess of stearic acid with glycerin. The excess stearic acid is then reacted with potassium and/or sodium hydroxide. That produces a substance that contains glyceryl stearate, potassium stearate, and/or sodium stearate.
Glyceryl stearate is a naturally derived fatty acid produced from citrate, glyceryl stearate and citric acid. When used as an emollient in skin care, it acts as a natural lubricant to help keep skin soft and smooth, and also creates a barrier to prevent moisture loss.
An emulsion is a mixture of two repel substances (water and oil).It induces a dispersion of undissolved material throughout a liquid. The dispersed phase is dispersed in the other continuous phase. Emulsions are unstable and thus tend to revert to the stable state of oil separated from water spontaneously. Physical energy such as shaking, stirring, homogenizers, or spray processes is needed to keep an emulsion. Surfactants increase the kinetic stability of emulsions and make the emulsion does not change significantly for long term. An emulsifier is a type of surfactant used to keep emulsion stable and well dispersed. Emulsifiers typically have a hydrophobic head and a hydrophilic tail in one molecule. The emulsifiers will surround an hydrophobic molecule and hydrophilic tail form a protective layer so that the oil molecules cannot "clump" together. This action helps keeps phase well dispersed. Some of the most important emulsifiers include salts or esters of higher fatty acids, fatty alcohols, esters of monoglycerides, gelatin, lecithins, polysaccharides and casein.
Glyceryl stearate is an emulsifying and stabilising ingredient; it allows oil and water-based ingredients to mix well together.
Glyceryl stearate is often combined with PEG-100 stearate to create an even more powerful stabiliser.

Glyceryl 1-stearate (Glycerol monostearate), commonly known as GMS, is an organic molecule used as an emulsifier. GMS is a white, odorless, and sweet-tasting flaky powder that is hygroscopic. It is a glycerol ester of stearicacid. It occurs naturally in the body as a product of the breakdown of fats by pancreatic lipase, and is also found in fatty foods. GMS is a food additive used as a thickening, emulsifying, anti-caking, and preservative agent; an emulsifying agent for oils, waxes, and solvents; a protective coating for hygroscopic powders; a solidifier and control release agent in pharmaceuticals; and a resin lubricant. It is also used in cosmetics and hair care products. Used in antiperspirants and deodorants, baby care, body care, facial care, sun care, conditioners, facial make-up, creams and lotions-skin care, sprayable emulsions, feet, hands and nails, self-tanning, nail grooming and color cosmetics. GMS is largely used in baking preparations to add "body" to the food. It is responsible for giving ice cream and whipped cream its smooth texture. It is sometimes used as an anti-staling agent in bread.

Glycerides (also known as acylglycerols) are esterified to glycerol with fatty acids. Glycerol haing three hydroxyl functional groups is esterified with one, two or three fatty acids to form monoglycerides, diglycerides and triglycerides respectively. A monolyceride is a compound consisting of one fatty acid chains covalently bonded to a glycerol molecule through ester linkage. Diglyceride and triglyceride consists of two and three fatty acid chains respectively. Examples of triglyceride include triacetin, trimyristin, and triolein. Monoglyceride usually occurs as an intermediate in triglyceride metabolism by means of a release of a fatty acid from lipase. The commercial source may be either animal or vegetable fats, and synthetically produced as well. Mono- and diglycerides are common food additives used as an emulsifier or stabilizer to blend together certain ingredients of oil-hating and water-hating, which would not otherwise blend well.

Glycerol monostearate, commonly known as gms, is a monoglyceride commonly used as an emulsifier in foods. It takes the form of a white, odorless, and sweet-tasting flaky powder that is hygroscopic. Chemically it is the glycerol ester of stearic acid.

In cosmetics and personal care products, Glyceryl Stearate is widely used and can be found in lotions, creams, powders, skin cleansing products, makeup bases and foundations, mascara, eye shadow, eyeliner, hair conditioners and rinses, and suntan and sunscreen products.

Why is Glyceryl Stearate used in cosmetics and personal care products?
Glyceryl Stearate acts as a lubricant on the skin's surface, which gives the skin a soft and smooth appearance. It also slows the loss of water from the skin by forming a barrier on the skin's surface. Glyceryl Stearate, and Glyceryl Stearate SE help to form emulsions by reducing the surface tension of the substances to be emulsified.
GMS is a food additive used as a thickening, emulsifying, anticaking, and preservative agent; an emulsifying agent for oils, waxes, and solvents; a protective coating for hygroscopic powders; a solidifier and control release agent in pharmaceuticals; and a resin lubricant. It is also used in cosmetics and hair-care products.
GMS is largely used in baking preparations to add "body" to the food. It is somewhat responsible for giving ice cream and whipped cream their smooth texture. It is sometimes used as an antistaling agent in bread.
It can also be used as an additive in plastic, where GMS works as an antistatic and antifogging agent. This is common in food packaging.

What Is Glyceryl stearate?
Glyceryl stearate, also called glyceryl monostearate, is a white or pale yellow waxy substance derived from palm kernel, olives, or coconuts.

What Does Glyceryl stearate Do in Our products?
Glyceryl stearate is an emollient that keeps products blended together; it can also be a surfactant, emulsifier, and thickener in food — often it’s used as a dough conditioner and to keep things from going stale. In our products, however, glyceryl stearate is used for its most common purpose — to bind moisture to the skin. For this reason, it is a common ingredient in thousands of cosmetic products, including lotions, makeup, skin cleansers, and other items.

Why Puracy Uses Glyceryl stearate
We use glyceryl stearate in several of our products as a moisturizer; it also forms a barrier on the skin and prevents products from feeling greasy. As an emulsifier, it also allows products to stay blended. Several studies and clinical tests find that glyceryl stearate causes little or no skin or eye irritation and is not a danger in formulations that might be inhaled, In addition, a number of clinical trials have found that glyceryl stearate in moisturizers can lessen symptoms and signs of atopic dermatitis, including pruritus, erythema, fissuring, and lichenification.In 1982 and again in 2015, the Cosmetic Ingredient Review deemed the ingredient safe for use in cosmetics. Whole Foods has deemed the ingredient acceptable in its body care quality standards.

How Glyceryl stearate Is Made
Glyceryl stearate is formed through a reaction of glycerin with stearic acid, which is a fatty acid that comes from animal and vegetable fats and oils. Glyceryl stearate SE, the self-emulsifying form of the substance, is made by reacting an excess of stearic acid with glycerin. The excess stearic acid is then reacted with potassium and/or sodium hydroxide. That produces a substance that contains glyceryl stearate, potassium stearate, and/or sodium stearate
Glyceryl stearate (GMS) is one of the most commonly used ingredients in personal care formulations. But it’s a material that is not well understood by most formulators. GMS (EU) is normally used as a low-HLB thickening agent in lamellar gel (EU) network (LGN)-based oil-in-water emulsions, often combined with fatty alcohols.
LGN-based emulsions containing thickening polymers are the most common type of oil-in-water formulations sold globally. Most GMS used in personal care products should actually be called glyceryl distearate (EU), since many common grades only contain around 40% alpha monostearate (EU), 5% glyceryl tristearate (EU), and 50% glyceryl distearate.
There are also grades commercially available that contain 30%, 60%, and 90% GMS. The 90% alpha mono grades can only be produced by molecular distillation and are widely used in the food industry.
Functionally, there is a big difference in performance if you use a 90% versus 40% mono. A 90% mono has a higher melting point (69°C versus 58-63°C), lighter skin feel, and a higher HLB (EU) (~4-5, versus ~3). The higher HLB of the 90% mono enables you to form LGNs much easier with lower emulsifier levels and energy than when using cetyl (EU)/stearyl alcohol (EU). There are also self-emulsifying (SE) grades of GMS available, which are typically combined with PEG 100 stearate (EU), potassium stearate (EU), or sodium lauryl sulfate (EU).
