Cosmetic Grade Polyglyceryl-3 Diisostearate CAS 66082-42-6
Products Description
- Polyglyceryl-3 Diisostearate is a versatile emulsifier and surfactant, widely used in cosmetics and personal care products. It is a polymer formed by the reaction of glycerol and diisostearic acid.
- Polyglyceryl-3 Diisostearate has good solubility in oil substances. For example, it can dissolve well in vegetable oils (such as olive oil, almond oil) and mineral oils. Meanwhile, it can also interact with water to a certain extent, thanks to the hydrophilicity provided by its polyglycerol structure. This solubility feature enables it to serve as an effective emulsifier to help form a stable emulsion system and blend the oil-phase and water-phase components together.
- Polyglyceryl-3 Diisostearate has excellent interfacial activity and can significantly reduce the surface tension at the oil-water interface. When used in formulations such as emulsions or creams, this property can prevent the aggregation of oil droplets and water droplets, thus keeping the emulsion in a uniformly stable state.
Function
- Emulsifier: Polyglyceryl-3 Diisostearate is mainly used as an emulsifier, which can help oil and water mix to form a stable emulsion. It is commonly used in skin creams, lotions and cosmetics.
- Surfactants: As a surfactant, Polyglyceryl-3 Diisostearate reduces the surface tension of water, helping cleaning products remove dirt and grease.
- Thickener: In some formulations, Polyglyceryl-3 Diisostearate can also act as a thickener to improve the texture and feel of the product.
- Skin Conditioning Agent: Polyglyceryl-3 Diisostearate has good skin affinity and can improve the product’s spreadability and usage experience.
Application
- Cosmetics
- Polyglyceryl-3 Diisostearate is widely used as an emulsifier in skin care products, such as emulsions, creams, and serums. For example, in a serum formulation containing multiple plant oils (such as jojoba oil, rosehip oil) and water-soluble active ingredients (such as vitamin C derivatives, hyaluronic acid), Polyglyceryl-3 Diisostearate can effectively emulsify the oil phase and water phase together to form a uniform serum. This not only contributes to the stability of the product but also enables the skin to better absorb the active ingredients therein.
- In cosmetic products, Polyglyceryl-3 Diisostearate can be used as a pigment dispersant. Taking lipstick as an example, it can help the pigments in the lipstick disperse evenly, making the lipstick color more vivid and uniform and making it smoother to apply. Meanwhile, it can also improve the texture of the product and enhance properties such as the waterproof performance of the product.
- Personal care products
- In products such as body washes and shampoos, Polyglyceryl-3 Diisostearate can be used as a thickener and emulsifier. In some body wash formulations containing natural oils (such as coconut oil, shea butter), it can help emulsify the oils with other cleansing ingredients and appropriately increase the product's consistency, giving the product a better texture during use.
- Food
- As a food additive, Polyglyceryl-3 Diisostearate is mainly used for food emulsification. In some cream products, chocolate products and other foods, it can prevent the separation of fats and oils and extend the shelf life of the food. For example, in chocolate products, it can make cocoa butter and other ingredients mix better and improve the taste and quality of the chocolate.
