Description

Propyleneglycolisostearate is a non-ionic ester derived from propylene glycol and isostearic acid, functioning as a versatile emollient and emulsifier. This compound is valued for its excellent skin feel, spreading properties, and ability to enhance the stability and texture of formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to create high-performance, stable, and luxurious end products.

Application

• As a primary emollient and skin-conditioning agent in creams, lotions, and body butters.
• Used as a co-emulsifier and stabilizer in oil-in-water (O/W) cosmetic emulsions.
• Functions as a viscosity modifier and texture enhancer in makeup products like foundations and lipsticks.
• Acts as a solubilizer and carrier for active ingredients in topical pharmaceutical preparations.
• Employed in hair care formulations such as conditioners and styling products for its lubricating and anti-static properties.
• Serves as a plasticizer and processing aid in certain polymer and industrial applications.
