For formulators in the cosmetics and personal care industry, understanding the specific functions of each ingredient is critical. CAS 9005-00-9, commonly recognized as Steareth-20, is a prime example of an ingredient whose technical properties are key to successful product creation. NINGBO INNO PHARMCHEM CO.,LTD. provides this essential cosmetic ingredient, understanding its vital role as a nonionic surfactant and emulsifier.

Steareth-20's chemical designation, CAS 9005-00-9, points to its composition as a polyethylene glycol ether of stearyl alcohol. This molecular structure grants it powerful emulsifying properties, allowing it to facilitate the mixing of oil and water – two substances that naturally repel each other. In cosmetic formulations, this means Steareth-20 can create stable emulsions, preventing the separation of ingredients and ensuring a uniform product consistency. This is fundamental for the quality and longevity of many creams, lotions, and serums.

The application of Steareth-20 as an emulsifier is widespread across the beauty industry. It is particularly valued for its ability to create stable oil-in-water (O/W) emulsions, which are common in skincare products due to their light and easily absorbed feel. Formulators often seek this specific cosmetic ingredient to achieve desired textures, enhance spreadability, and ensure that active ingredients are evenly distributed within the product. The decision to buy Steareth-20 often stems from its proven reliability in these applications.

Beyond emulsification, Steareth-20 also contributes to the overall performance of personal care items. It can act as a solubilizer, helping to incorporate fragrances and other oil-soluble components into water-based systems, thereby improving the overall sensory profile of the product. As a cosmetic raw material, its impact on the final product's texture and user experience is significant.

NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying formulators with the critical components they need. By understanding the detailed function of ingredients like Steareth-20 (CAS 9005-00-9), businesses can confidently develop innovative and high-quality personal care products. Its role as a robust emulsifier and stabilizer makes it an indispensable tool in the cosmetic formulator's arsenal.
