As a cornerstone in cosmetic raw materials, protein has a variety of effects and can be used in skin and hair care products, offering both efficacy and safety. And also plays an essential role in the structure of skin and hair.
We, Seiwa Kasei, with decades of unwavering dedication to protein exploration, contributing to the development of almost 100 products forming the Promois™ series.
Promois™ series includes hydrolysed proteins and their derivatives from various origins. Our advanced technology enables precise control over molecular weights and the creation of varied derivatives stands out for its remarkable properties.
Property
- Adsorption and penetration to hair and skin.
- Moisturising effect.
- Repairing and protecting damaged hair and skin.
Protein origin
Promois™ series is derived from various origins, including plants and in alignment with the growing demand for botanical and eco-friendly cosmetics.
There are also a number of ingredients that are in line with the upcycling concept.
Each origin boasts unique efficacies, providing consumers with a tailored selection based on individual needs.
Molecular weight
Understanding the importance of molecular weight in the hair repairing process, Seiwa Kasei offers a range of products to meet different needs. Those with lower molecular weights penetrate into the hair and fill in the damaged parts, facilitating repair. Conversely, higher molecular weight proteins attach to the surface of the hair, forming a protective layer on the hair surface.
Derivatives
Delving deeper into innovation, the hydrolysed protein derivative series enriches the cosmetic landscape. The hydrolysed protein derivative series is a range of raw materials with special properties brought about by chemically modifying the hydrolysed protein to make it suitable for incorporation into cosmetics
With silylated (SIG series), acylated (E series), cationic (Q/CAQ/SAQ series), and ethyl esterified (A series) derivatives, SEIWA KASEI ensures a diverse range of options, each with unique characteristics. Allowing cosmetic creators to tailor their formulations precisely.
Promois™ series not only elevates cosmetic formulations with cutting-edge technology but also aligns with the evolving preferences for sustainable and effective beauty solutions. Experience the transformative power of proteins in cosmetics, unlocking a new era of skincare and haircare excellence.
