POLYSORBATE 85

Description

Polysorbate 85 is a versatile synthetic compound widely used in skincare and cosmetic formulations. This nonionic surfactant and emulsifier is derived from sorbitol and oleic acid, making it an effective agent for blending oil and water-based ingredients. Polysorbate 85's molecular structure consists of a hydrophilic polyoxyethylene head and a lipophilic fatty acid tail, allowing it to stabilize emulsions and enhance the solubility of various ingredients.

In skincare products, Polysorbate 85 serves multiple functions. It acts as an emulsifier, ensuring uniform distribution of active ingredients throughout the formulation. This property is particularly beneficial in lotions, creams, and serums containing both oil-soluble and water-soluble components. Additionally, Polysorbate 85 aids in the dispersion of fragrances and essential oils, improving the overall sensory experience of the product.

The ingredient also functions as a mild cleansing agent, helping to remove excess oils and impurities from the skin without causing excessive dryness. Its low potential for irritation makes it suitable for use in products designed for sensitive skin types. Polysorbate 85 is generally considered safe for topical use when formulated in appropriate concentrations.
