Polysorbate 85 is a nonionic surfactant and
Emulsifier commonly used in cosmetics and personal care products. It is an amber liquid with good solubility and is soluble in a variety of organic solvents such as water, ethanol, vegetable oil and ethyl acetate. Its structure and performance are suitable for oil-in-water (O/W) emulsion systems. The conventional packaging is 25kg/barrel, which not only meets the needs of small-scale research and development, but also is suitable for industrial applications. It is a raw material choice that balances functionality and practicality.
General characteristics
Polysorbate 85 has excellent emulsification, dispersing and solubilization capabilities, and can effectively resist the damage of ionic strength changes and pH fluctuations to the emulsion system, maintaining the structural stability and uniform texture of the formula. In the face of environmental changes (such as temperature, humidity) or complex ingredient systems, it can still show good compatibility and continuous emulsification ability. The recommended addition amount is 1–5%, usually introduced during the oil phase heating stage to ensure emulsification efficiency and system consistency.
Uses in cosmetics
This ingredient is widely used in bath oils, makeup removers, massage oils, various skin care products, hair care products, and sunscreen products. It is used to evenly disperse the oil phase ingredients in the water phase, improve the stability of the emulsion, and prevent stratification and oil separation. Its low irritation and good compatibility allow it to be used in conjunction with a variety of active ingredients to improve the skin feel of the product while maintaining a balanced effect. All batches leaving the factory must pass key project tests such as appearance, odor, density, and moisture to ensure stable and reliable quality. It is a key ingredient to improve formula consistency and tolerance.
