Natto Gum

Natto gum is a natural polysaccharide derived from natto, a traditional fermented soybean product. It functions primarily as a film-forming agent in skincare formulations, helping to create a protective layer on the skin's surface and contribute to product texture and stability.As a plant-based ingredient, natto gum aligns with formulations that prioritise naturally derived materials. Its film-forming properties make it useful in products designed to provide a smooth application and even coverage, though its presence in skincare remains relatively uncommon at present.

Natto gum forms a thin, cohesive film across the skin when applied. This layer helps to seal moisture and active ingredients closer to the skin whilst creating a smooth, uniform finish. The mechanism relies on the gum's natural polymeric structure, which allows it to bind to the skin's surface through weak molecular interactions.

Natto gum is typically incorporated into formulations by manufacturers rather than used as a standalone ingredient. It works best in products designed to provide coverage and even application, such as primers, tinted moisturisers, or light serums. Use as directed on your product's label.

Natto gum is generally regarded as safe for topical use and is derived from a food-grade source. Those with soya sensitivities should check ingredient lists, though topical exposure poses lower risk than ingestion.
