| Product Name | Polyhydrostearic Acid |
| CAS | 27924-99-8 |
| Structure |  |
| Description | Polyhydroxystearic acid (PHS) is a synthetic wax-like substance that is commonly used as an emulsifier in cosmetics and personal care products. Its emulsifying properties make it useful in creating stable emulsions, which are mixtures of oil and water that would normally separate. In particular, PHS is used in sunscreens to improve their texture, spreadability and reduce the greasiness that some sunscreens can have. It also helps the sunscreen to adhere to the skin, ensuring even application of the product. |
| Appearance | fine white or yellowish powder with a slightly waxy texture |
| Application | 1. Polyhydroxystearic acid is commonly used as an emulsifier in cosmetic products such as sunscreens, lotions, and creams. 2. The acid has excellent dispersing properties, helping to evenly distribute pigment in makeup products like foundations and powders. 3. It also works as a thickening agent, giving viscosity to lotions and creams, and preventing makeup products from running or dripping. 4. When used in sunscreens, polyhydroxystearic acid helps to increase the UV protection factor (SPF) by enhancing the dispersal of zinc oxide and titanium dioxide particles. 5. Due to its stability, polyhydroxystearic acid is also used in food packaging to help prevent the absorption of flavors and odors. 6. It is used in the manufacturing of textiles and paper products, to improve the processability and physical properties of these materials. 7. In the pharmaceutical industry, it is used as a disintegrant in tablets and capsules, aiding in the breakdown of the tablet or capsule for easier absorption in the body. 8. It also finds applications in the production of lubricants, plasticizers, and resins. |
