Biobased film former for perfect hairstyling
| Subj: Press-releses
Covestro has developed a film-forming polyurethane (PU) dispersion for hairstyling products with a carbon content based on 58 percent biomass. The film former called Baycusan® eco E 1000 achieves the excellent performance level of synthetic acrylate polymers, in particular in formulations where a long-lasting hold and a good humidity resistance are critical.
Baycusan® eco E 1000 is the first product of the new eco series of film formers, which are based on renewable resources by more than 50 percent. Thus they fulfill the requirements of ISO standard 16128 part 1 to be designated as a naturally derived ingredient. Covestro already announced the series at In-Cosmetics Global trade fair in Amsterdam in April 2018.
The new film former will be officially presented to a professional public for the first time at the 2018 SEPAWA Conference, the most important meeting of the cosmetics, perfume, and cleaning agent industry in Europe. It will take place from October 10 to 12, 2018 in Berlin.
New opportunities for the cosmetics industry
Getting hair into shape
The laboratory also tested reference formulas in comparison, for instance, for their high humidity curl retention properties or using the so-called “curl snap test.” It revealed that hair strands treated with styling formulations based on Baycusan® eco E 1000 maintained their original curl shape — even after they were repeatedly stretched by hand. They proved even better than formulations with other classic and synthetic film formers not based on polyurethane chemicals.
Good heat protection
All in all, the new biobased film former Baycusan® eco E 1000 opens up excellent possibilities for increasing the naturalness of cosmetic products, without having to make compromises in styling and quality. The product also has promising properties for use in hair conditioner formulas. Covestro is currently completing further tests for this application.
