High Quality Polyglyceryl-2 Dipolyhydroxystearate CAS 156531-21-4
Products Description
- Polyglyceryl-2 Dipolyhydroxystearate is a versatile emulsifier and surfactant, widely used in cosmetics and personal care products. It is a polymer formed by the reaction of glycerol (Glycerol) and dipolyhydroxystearic acid (Dipolyhydroxystearic Acid).
- Polyglyceryl-2 Dipolyhydroxystearate has good solubility in lipid substances. For example, it can dissolve well in various vegetable oils (such as soybean oil, corn oil) and animal fats (such as lanolin). It also shows certain solubility in some organic solvents (such as ethanol, isopropyl alcohol, etc.). However, its solubility in water is relatively weak, but it can play an emulsifying role in an appropriate emulsifying system to mix the oil phase and water phase.
- Polyglyceryl-2 Dipolyhydroxystearate' s viscosity characteristics are rather complex and will change depending on factors such as concentration and temperature. At higher concentrations, it may exhibit higher viscosity, thus affecting the texture of the product. For example, in some cream cosmetics, it can help increase the product's consistency.
Function
- Emulsifier: Polyglyceryl-2 Dipolyhydroxystearate 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-2 Dipolyhydroxystearate reduces the surface tension of water, helping cleaning products remove dirt and grease.
- Thickener: In some formulations, Polyglyceryl-2 Dipolyhydroxystearate can also act as a thickener to improve the texture and feel of the product.
- Skin Conditioning Agent: Polyglyceryl-2 Dipolyhydroxystearate has good skin affinity and can improve the product’s spreadability and usage experience.
Application
- Cosmetics
- In terms of skin care products, Polyglyceryl-2 Dipolyhydroxystearate is often used in emulsions, creams, and eye creams. In creams, as an emulsifier, it can emulsify oil-soluble moisturizing ingredients (such as petrolatum, squalane) and water-soluble moisturizing ingredients (such as glycerol, sodium hyaluronate) well together to form a stable cream structure, prevent the cream from separating, and at the same time provide a good moisturizing effect. In eye care products, it helps reduce the greasy feeling and makes the product easier to be absorbed by the skin around the eyes.
- In cosmetic products such as foundations and lipsticks, Polyglyceryl-2 Dipolyhydroxystearate can be used as a thickener and dispersant. In foundations, it can adjust the texture of the product, making the foundation finer and more adherent, and can also increase the concealing power of the foundation. In lipsticks, it helps pigments disperse evenly and improves the color uniformity and stability of the lipsticks.
- Food
- As a food additive, Polyglyceryl-2 Dipolyhydroxystearate is mainly used to improve the texture and stability of food. In some foods with a high fat content (such as baked goods, fried foods), it can prevent oil from seeping out and extend the shelf life of the food. In dairy products (such as cream, cheese), it can optimize the taste and texture of the product, making it finer and smoother.
- Pharmaceutical
- In some external drug formulations, such as ointments and creams, Polyglyceryl-2 Dipolyhydroxystearate can be used as a matrix component. It can help drugs disperse evenly and can adjust the consistency of the formulation, making the drug easier to apply to the skin. Meanwhile, it also contributes to the stability and release performance of the drug.
