Glyceryl stearate is an ester derived from glycerol and stearic acid, both naturally occurring substances. It is a common ingredient in skin care and cosmetic formulations and serves a variety of functions in personal care products. It has hydrophilic (water-absorbing) and lipophilic (oil-absorbing) properties.
Functions in skin care and cosmetics
- Emollients: Glyceryl stearate acts as an emollient, helping to soften and smooth the skin by forming a protective layer on the skin's surface.
- Emulsifier: It acts as an emulsifier in formulations, allowing water and oil-based ingredients to mix to form a stable and homogeneous product.
- Stabilizer: Glyceryl stearate helps stabilize the formula and prevents the oil and water phases from separating.
- Texture Enhancer: It improves the texture of skin care products, providing a luxurious creamy feel.
- Moisturizer: Although primarily an emollient, it also contributes to the overall moisturizing effect of the product.
- Moisturizing: Glyceryl stearate helps hydrate the skin by locking in moisture and preventing moisture loss.
- Smooth skin: Its emollient properties help make skin texture smoother and softer.
- Enhanced spreadability: In formulations such as creams and lotions, it improves the spreadability of the product on the skin.
Glyceryl stearate is found in a variety of skin care and cosmetic products, including moisturizers, creams, lotions, sunscreens, and cosmetics.
Glyceryl stearate is generally considered safe for use in cosmetics and personal care products. Most people tolerate it well.
It is often combined with other emollients, humectants and active ingredients to create a balanced formula.
While it is not typically comedogenic, individuals with specific skin sensitivities or conditions should check product labels for potential allergens.
Glyceryl stearate has been approved by regulatory agencies in several countries for use in cosmetics and personal care products. It meets safety and quality standards for skin care applications.
As with any skin care ingredient, individual reactions may vary. If you have a specific skin concern or condition, it is recommended to perform a patch test or consult a dermatologist before using products containing glyceryl stearate, especially if you have a history of skin sensitivities or allergies.
