Polyhydroxystearic Acid for Makeup CAS NO 27924 99 8
Polyhydroxystearic acid is a high-performance dispersant, known for its excellent pigment stability and anti-agglomeration ability. It is a yellow liquid, easy to process, and has stable performance in sunscreens, makeup and other products.In addition to the dispersing effect, it also has an auxiliary emulsifying function, and has excellent compatibility with a variety of cosmetic oils and sunscreens.
How It’s Engineered
Its molecular structure is designed in a balanced manner, which can effectively wet and wrap inorganic pigments such as titanium dioxide and zinc oxide, reduce the viscosity of the pigment slurry, and allow higher pigment loads while maintaining fluidity.The surface activity properties contribute to emulsification, especially when combined with the main
Emulsifier such as PEG-30 dimerhydroxystearate, the effect is better.Which means that can increase the pigment content while avoiding heavy or agglomeration of the formula.
What Makes It Perform
Polyhydroxystearic acid can achieve excellent pigment dispersion, bringing smooth texture and uniform color; film-forming properties can enhance makeup holding and lock in water; it is resistant to electrolytes and stable in complex systems; it has good compatibility with polar and non-polar oils and expands the possibility of formulation.You will get raw materials that combine multiple effects.
Practical Applications
The recommended addition amount is 1%-5%, depending on the pigment concentration and product type, suitable for slurry grinding, sunscreen, BB cream, foundation, lipstick, etc.It is recommended to dissolve in the carrier oil phase before adding the powder.In combination with sorbitan sesquioleic acid ester, it can improve the stability of the oil-in-water system and the wetting properties of pigments.Which will allow you to easily meet the challenges of high pigment formulas and create delicate products.
