POLYSORBATE 21

Description

Polysorbate 21, also known as laureth-21, is a versatile synthetic emulsifier and surfactant commonly used in skincare and cosmetic formulations. This nonionic compound is derived from ethoxylated lauryl alcohol and is prized for its ability to stabilize oil-in-water emulsions, enhance product texture, and improve the solubility of various ingredients.

In skincare applications, Polysorbate 21 serves as an effective emollient, helping to soften and smooth the skin while reducing transepidermal water loss. Its emulsifying properties allow for the seamless blending of oil-based and water-based components, resulting in stable and homogeneous products. This ingredient is particularly useful in cleansers, moisturizers, and serums, where it aids in the even distribution of active ingredients across the skin's surface.

Polysorbate 21 also functions as a mild surfactant, assisting in the removal of dirt, oil, and makeup without overly stripping the skin's natural oils. Its low potential for irritation makes it suitable for use in formulations designed for sensitive skin types. Additionally, this ingredient can help improve the spreadability of products, enhancing their overall user experience and efficacy.
