What Water Solu does

Water Solu is the water-soluble ingredients brand of Keep Ingredients Co., Ltd., a privately held Chinese natural ingredient manufacturer headquartered in Xi'an, Shaanxi, China. Keep Ingredients was founded in 2012, and Water Solu was established as a focused subsidiary in 2020 to commercialize a portfolio of 100% water-soluble natural ingredients spanning proteins/peptides, nutritional ingredients, botanical extracts, natural colors, beverage powders, and liquid extracts. The company sells to manufacturers in the food, beverage, nutraceutical, and cosmetics industries, with a stated customer base of 6,000+ clients across the USA, Europe, and Asia. It positions itself on price competitiveness at 5-20% below competitors, supported by vertically integrated raw material sourcing through its own planting bases.

The company's technology stack is built around proprietary extraction and processing methods including cold extraction, enzymatic hydrolysis, spray-drying, freeze-drying, and liposome encapsulation. Notable product extensions include sialic acid, liposomal ingredient formats, and emerging nutraceutical products such as NMN and NAD+. Reported production capacity is 40+ tons/month for extracts, 1000+ tons/year for flavors, 1000+ tons/year for tea products, and 20+ tons/month for sialic acid. The company holds certifications including BRC, FDA, ISO22000, KOSHER, HALAL, HACCP, and CGMP, and supports its R&D with university partnerships and a research-heavy staff composition (40% researchers).

Water Solu operates a B2B ingredient supply model with three relevant revenue mechanics: direct ingredient sales to OEMs, contract manufacturing (OEM/ODM) services, and category-specific specialty products (e.g., sialic acid, liposomal formats). International distribution is supported through a 50+ language website and certifications that enable access to regulated markets. The company is private, has not disclosed revenue, and has no public funding rounds or M&A activity in the input.
