Pittsburgh, Pennsylvania -- Bayer MaterialScience's "ultrapure synthetic polyurethane dispersions" range -- Baycusan C -- meets "key requirements" for the cosmetics industry, a 22 April company statement said.
Based on water and containing no preservatives or co-solvents, the PU dispersions were designed by BMS specifically for the cosmetics industry.
"We are able to offer Baycusan C products without preservatives because they are manufactured and filled at our plant in Chempark Dormagen using a germ-free, ultraclean and high-quality process developed in-house," said Steffen Hofacker, head of cosmetics at Bayer MaterialScience.
"As a result, the raw materials give cosmetic companies freedom to design their products as they see fit and to preserve them in line with the appropriate statutory requirements," he said.
Hofacker added that the Baycusan C range includes a polyurea powder as a sensory additive and four solvent-free polyurethane dispersions with film-forming and conditioning properties. "These raw materials can be beneficial for skin-care products, decorative cosmetics, sun-care and hair styling products," he added.
According to BMS, the dispersions also create a minimum amount of waste during processing and use mild energy-efficient procedures for chemical reactions. (RD)
