ISOSTEARETH-15

Description

ISOSTEARETH-15 is a versatile emulsifier and surfactant commonly used in skincare and cosmetic formulations. This synthetic ingredient is derived from isostearic acid and ethylene oxide, resulting in a nonionic compound with excellent emulsifying properties. Its primary function is to stabilize oil-in-water emulsions, ensuring a smooth and consistent texture in various products.

The "15" in ISOSTEARETH-15 refers to the average number of ethylene oxide units in the molecule, which influences its hydrophilic-lipophilic balance (HLB). This specific balance allows it to effectively blend oil and water-based ingredients, making it particularly useful in creams, lotions, and cleansers. ISOSTEARETH-15 also exhibits mild cleansing properties, helping to remove dirt and excess oils from the skin without causing excessive dryness.

In addition to its emulsifying capabilities, ISOSTEARETH-15 acts as a solubilizer, aiding in the incorporation of fragrances and essential oils into water-based formulations. It is generally well-tolerated by most skin types and is considered to have low irritation potential. This ingredient is often preferred in formulations designed for sensitive skin due to its gentle nature and ability to create stable, elegant products.
