ISOSTEARETH-25

Description

ISOSTEARETH-25 is a versatile emulsifier and surfactant commonly used in skincare and cosmetic formulations. This synthetic ingredient is derived from isostearic acid, a branched-chain fatty acid, and ethylene oxide. Its primary function is to help blend oil and water-based components, creating stable emulsions in various products.

With an HLB (Hydrophilic-Lipophilic Balance) value of approximately 15, ISOSTEARETH-25 is particularly effective in oil-in-water emulsions. It contributes to the smooth texture and even distribution of active ingredients in creams, lotions, and serums. This compound also acts as a mild cleansing agent and can enhance the foaming properties of products.

ISOSTEARETH-25 is known for its ability to improve the spreadability of formulations, making it easier for products to be applied evenly on the skin. It can also help to solubilize fragrances and essential oils, ensuring their uniform dispersion throughout the product. Additionally, this ingredient may assist in stabilizing emulsions over time, potentially extending the shelf life of skincare products.

While generally well-tolerated, as with any cosmetic ingredient, patch testing is recommended for individuals with sensitive skin or known allergies.
