Baycusan® C 1004

Technical Datasheet | Supplied by Covestro in-cosmetics global 2019
Polyurethane-35. Baycusan® C 1004 by Covestro acts as a film forming, toning and firming agent. It is a colloidal system of a high molecular weight polyurethane polymer dispersed in water. An internal emulsifier is incorporated into the polymer backbone to ensure stability of the dispersion. Therefore, the use of external surfactants is not required. The polymer structure contains both hydrophilic and hydrophobic segments, which impart a unique combination of water resistance and ease of removal from skin. It imparts non-transfer resistant properties to decorative cosmetics. It displays a good balance of properties like outstanding water resistance, great aesthetics, non-greasy and non-sticky feel on the skin, excellent spreadability, good non-transfer properties, good adhesion to skin, fast drying, excellent abrasive resistance, good washability, etc. It allows for very water-resistant emulsions with a sand resistance effect. It is a biocide-free product suitable for various emulsions type and cold processes. It combines safe and easy application with comfortable long-term protection. It is gentle and suitable for matured & sensitive skin. Baycusan® C 1004 can be incorporated into oil-in-water and water-in-oil emulsions as well as in multiple emulsions, gels and gel creams.
