General Description:
E.G.M.S., or Ethylene Glycol Monostearate, is an ester derived from the reaction of ethylene glycol with stearic acid. It is a waxy, solid substance that is commonly used in the cosmetic industry for its emulsifying and opacifying properties. E.G.M.S. is often found in personal care products where a pearlescent or creamy appearance is desired.
Uses in the Cosmetic Industry:
E.G.M.S. serves several functions in cosmetic formulations:
- Opacifier: E.G.M.S. is used to create a creamy or pearlescent appearance in products such as shampoos, body washes, and lotions. It helps to give these products a rich, luxurious look.
- Emulsifier: It acts as an emulsifying agent, helping to blend water and oil phases in formulations. This ensures a stable and uniform mixture, enhancing the texture and consistency of the product.
- Viscosity Modifier: E.G.M.S. can also increase the thickness or viscosity of cosmetic formulations, improving their application and feel on the skin.
- Moisturizer: While not primarily a moisturizing agent, E.G.M.S. contributes to the overall moisturizing properties of a product by helping to retain moisture on the skin.
Potential Hazard Considerations:
E.G.M.S. is generally considered safe for use in cosmetics, but there are some potential hazards to consider:
- Skin Irritation: In some cases, E.G.M.S. may cause mild skin irritation, particularly in individuals with sensitive skin. It is important to ensure that the concentration used in formulations is within safe limits.
- Comedogenicity: While E.G.M.S. is not highly comedogenic, it may contribute to pore-clogging in individuals with very oily or acne-prone skin. Formulators should consider the skin type of the target audience when including this ingredient.
- Ethylene Glycol Concerns: Ethylene glycol, from which E.G.M.S. is derived, can be toxic in large amounts. However, the levels present in E.G.M.S. used in cosmetics are generally low and within safe limits. It is still important to ensure that the product complies with regulatory standards.
- Environmental Impact: E.G.M.S. is biodegradable, but like many cosmetic ingredients, it should be used responsibly to minimize environmental impact. Sustainable sourcing of stearic acid and proper waste management practices are important considerations.
CAS Number: 123-94-4
INCI: Ethylene Glycol Monostearate Glyceryl
Composition: Ethylene Glycol Monostearate Glyceryl is an ester compound formed by the reaction of stearic acid with glycerin. Its chemical formula is C21H42O4.
Purity Grade: No purity grade applicable
Appearance: Glyceryl Monostearate typically appears as a white to off-white, waxy solid or flakes at room temperature.
Solubility: Glyceryl Monostearate is practically insoluble in water but soluble in organic solvents such as ethanol, ether, and chloroform. It disperses in water to some extent, forming stable emulsions.
Preservation: Glyceryl Monostearate itself does not possess preservative properties. However, it is often used in formulations alongside other preservatives to prevent microbial growth and ensure product stability.
Storage: Store in a closed container at a dry place at room temperature
Raw Material Source: The raw materials for Glyceryl Monostearate synthesis include stearic acid, which can be derived from natural sources such as vegetable oils, and glycerin, which is obtained from fats and oils through hydrolysis.
Manufacture: Glyceryl Monostearate is synthesized through the esterification reaction between stearic acid and glycerin. The reaction is typically catalyzed by an acidic or basic catalyst under controlled conditions. The resulting product is then purified and processed into the desired form, such as flakes or pellets.
