Product Description

Steareth-21

Steareth-21 is a polyethylene glycol ether of stearic acid and is a particle compound. When used in cosmetics and personal care products, Steareth ingredients reduce the intermolecular forces between liquid molecules, enabling the formation of an emulsion. Without an ingredient like Steareth, the components of some personal care products may separate, much like the separation of water and oil.

We introduce Steareth-21, a premium non-ionic emulsifier designed to revolutionize your skincare formulations. This high-performance ingredient is engineered to create exceptionally stable emulsions, delivering luxurious textures and enhanced product efficacy in creams, lotions, and serums.

Why Choose Steareth-21?

  • Optimal Emulsion Stability: Ensures long-lasting formulation integrity and prevents separation.
  • Silky Skin Feel: Creates elegant, non-greasy textures for premium skincare products.
  • Broad Compatibility: Works seamlessly with various oils and active ingredients.
  • Formulation Versatility: Ideal for anti-aging products, moisturizers, and SPF formulations.
