Description

Isosteareth-2 is a non-ionic surfactant and emollient derived from isostearyl alcohol, functioning as a versatile chemical intermediate and formulation component. Its value lies in its excellent solubilizing, emulsifying, and skin-conditioning properties, making it a key ingredient for creating stable, high-performance products. This compound is essential for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to enhance product texture, stability, and sensory profile.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and sun care products.
• Solubilizer for fragrances, essential oils, and active ingredients in clear gels and aqueous formulations.
• Key ingredient in hair care products such as conditioners and styling aids for its conditioning and antistatic effects.
• Used in pharmaceutical topical preparations as an emollient and to improve drug delivery.
• Intermediate in the synthesis of other specialty ethoxylated surfactants and esters.
• Component in industrial applications requiring wetting and dispersing agents.
