Seiwa Kasei, a prominent Japanese ingredient supplier renowned for its innovative approach to skincare and haircare solutions, has unveiled its latest breakthrough: Promois WR-SP, a 100% pure hydrolyzed rice protein powder.

This new offering is set to revolutionize beauty regimens with its promise of delivering silky smooth hair and skin, all without the typical additives and preservatives found in many cosmetic products.

The cornerstone of Seiwa Kasei's Promois WR-SP lies in its unique formulation inspired by the concept of "botanical silk."

Derived from rice, this hydrolyzed protein contains essential amino acids such as glycine and alanine, which are fundamental components of silk protein. These properties not only enhance the product's efficacy but also contribute to its silky texture, mimicking the luxurious feel of silk itself.

Promois WR-SP was honored with the prestigious BSB Innovation Award at In-Cosmetics Global Paris for its exceptional performance in improving hair manageability, characterized by its silk-like smoothness and enhanced combing capabilities.

Applications for Promois WR-SP span across a wide range of beauty products, including facial care, body care, hand and foot treatments, and various conditioning treatments.

Its versatile benefits include hair conditioning, frizz control, strengthening and repair, anti-split ends properties, as well as moisturizing and hydrating effects.

Unlike traditional conditioners, this organic ingredient is certified by Ecocert and Cosmos, ensuring adherence to rigorous standards of sustainability and purity.

Moreover, Seiwa Kasei's commitment to innovation extends beyond Promois WR-SP. The company also received acclaim for Amitose GCA, a vitamin C derivative renowned for its emulsifying properties, further solidifying its reputation as a leader in cosmetic advancements.

Promois WR-SP's efficacy as a hydrolyzed rice protein is bolstered by its ability to deeply condition and moisturize both hair and skin.

Rich in acidic amino acids, rice protein offers superior moisture retention compared to other vegetable proteins, making it highly absorbable and effective in nourishing the hair and skin.

Additionally, this product aligns with various labeling claims including Clean at Sephora, Credo Clean Standard, and Ulta Beauty's Conscious Beauty.
