Natto Gum is a natural, high-molecular-weight polymer primarily composed of γ-polyglutamic acid (γ-PGA). It is produced by fermentation of soy protein with Bacillus subtilis var. natto (the same bacterium used in traditional Japanese natto food). This biodegradable, plant-derived ingredient forms a moisture-retaining film on the skin, offering superior humectancy (up to 5,000 times its weight in water), long-lasting hydration, and a smooth, non-sticky feel. Natto Gum is popular in moisturizers, serums, masks, eye creams, anti-aging products, and hair care. It provides intense hydration, plumping, barrier support, and a luxurious skin feel, often marketed as a natural collagen alternative or "phytocollagen."

What is NATTO GUM used for?
- Film forming / Moisturizing: Creates a breathable, moisture-locking film on the skin. Frequently used in creams, serums, masks, and eye products for long-lasting hydration and a plump, dewy appearance.
- Skin conditioning: Improves skin softness, elasticity, and barrier function. Ideal for dry, dehydrated, or mature skin formulations targeting moisture retention and smoothness.
- Texture enhancer: Provides a silky, non-sticky feel and enhances product glide. Common in lightweight gels, lotions, and hair treatments for elegant sensorial properties without greasiness.
Origin
Natto Gum is produced through microbial fermentation of soy protein (or soybean extract) using Bacillus subtilis var. natto. The bacterium secretes γ-polyglutamic acid as a mucilage, which is harvested, purified, and concentrated into a viscous liquid or powder. This biotech process is renewable, sustainable, and vegan-friendly, yielding a high-purity polymer that mimics natural skin moisturizing factors with exceptional water-binding capacity.

SMOOTHINGSafety Profile
Natto Gum is considered safe for cosmetic use. It has a very low hazard rating from EWG (typically 1) and minimal concerns for irritation, sensitization, or toxicity at typical concentrations (0.1-5%). It is non-comedogenic, well-tolerated across skin types (including sensitive), and poses low risk. Rare allergic reactions may occur in those sensitive to soy or fermentation products. Patch testing is recommended.
