Glycereth-31 is a highly ethoxylated derivative of glycerin, produced by reacting glycerol with ethylene oxide, resulting in a polyether compound with strong hydrophilicity.
Glycereth-31 belongs to the polyethylene glycol (PEG) ether family, widely used in cosmetic and pharmaceutical formulations due to its excellent water-binding, solubilizing, and texture-modifying properties.

Glycereth-31 is a highly versatile ingredient, primarily functioning as a humectant to enhance skin hydration by attracting and retaining moisture.
Glycereth-31 also plays a key role in formulation, improving texture and supporting cleansing properties.
GLYCERETH-31 is a valuable multi-functional ingredient, prized for its humectant properties that promote skin hydration, alongside its contributions to product texture and cleansing efficacy, with a confirmed safety profile when properly formulated.

Glycereth-31 is a water-soluble emollient and humectant derived from glycerin, widely used in cosmetic and personal care formulations for its moisturizing and skin-conditioning properties.
Glycereth-31 functions primarily by attracting and retaining water in the skin, thereby improving hydration and enhancing the overall feel of a product.
Due to its lightweight and non-greasy nature, Glycereth-31 is commonly incorporated into creams, lotions, serums, cleansers, and hair care products where a smooth, soft after-feel is desired without heaviness or residue.

USES and APPLICATIONS of GLYCERETH-31:
Glycereth-31 offers plasticizing properties with warming effect.
Glycereth-31 is used in heat-activated conditioners, styling aids and massage creams.
Glycereth-31 is used in cosmetic formulations as a moisturizer (preserves skin moisture), solvent and viscosity regulator (increases or decreases the viscosity of cosmetic products)

Uses / Applications of Glycereth-31: Cosmetics & Personal Care:  Moisturizers, Creams and lotions, Serums, Hair conditioners, Deodorants / antiperspirants, Cleansers, Formulation Roles, Humectant (hydration agent), Solubilizer for actives/fragrance, Emulsion stabilizer, Rheology modifier.
In applications, Glycereth-31 is frequently used in moisturizers, anti-aging products, sunscreens, and cleansing formulations to boost hydration and improve sensory attributes.

In hair care, Glycereth-31 helps maintain moisture balance and adds softness without weighing the hair down.
Overall, its multifunctional nature, safety profile, and effectiveness as a humectant make Glycereth-31 a valuable ingredient in modern cosmetic science.
One of the key benefits of Glycereth-31 is its ability to improve skin texture by reducing dryness and roughness, making it particularly valuable in formulations aimed at sensitive or dehydrated skin.

Glycereth-31 also contributes to product stability and spreadability, allowing formulations to glide more easily over the skin.
Additionally, Glycereth-31 can act as a solvent for certain active ingredients, helping to enhance their delivery and uniform distribution within a product.
From a formulation perspective, Glycereth-31 is valued for its mildness and compatibility with a wide range of ingredients, including both hydrophilic and some lipophilic components.

Glycereth-31 is generally non-irritating and suitable for use in products intended for daily application.
Glycereth-31's chemical structure, consisting of glycerin ethoxylated with approximately 31 units of ethylene oxide, provides a balance between hydrophilicity and functional versatility.
Glycereth-31 is widely used in cosmetic and personal care formulations due to its multifunctional performance as a humectant, emollient, and solvent.
