Yeast Polysaccharides

Product Description

Green Stone Swiss manufactures cosmetic-grade Yeast Polysaccharides from yeast cell-wall fractions under GMP-aligned process controls, targeting consistent polysaccharide content and reliable batch-to-batch performance. Direct factory supply supports bulk orders with full technical documentation and free sample support for laboratory qualification and scale-up.

Yeast Polysaccharides are the polysaccharide fraction of the yeast cell wall, typically obtained from Saccharomyces cerevisiae and commonly comprising glucan and mannan components rather than a single defined molecule. These high-molecular-weight carbohydrates bind water and can form a light, breathable film at the skin surface, supporting moisture retention, skin-conditioning feel, and a physical contribution to skin protection. The ingredient remains stable in aqueous solution under typical cosmetic pH and may also contribute modest viscosity in water-based systems, with formulation compatibility across serums, gels, and emulsions.

Brands building yeast-derived hydration and barrier-care lines use this grade as a water-phase, film-forming polysaccharide for sensitive-skin, mask, and leave-on emulsion programs. GSS supplies bulk quantities with COA and TDS support so procurement and R&D teams can specify Yeast Polysaccharides as a high-purity cell-wall polysaccharide, distinct from yeast peptides or purified single-assay beta-glucan grades.

Key Benefits & Applications

Yeast Polysaccharides is a film-forming yeast cell-wall polysaccharide used in professional hydration, barrier-care, and comfort-focused leave-on formulas.

• Forms a light, water-binding film that supports surface hydration and skin-conditioning feel
• Helps limit transepidermal water loss and reinforce perceived barrier comfort in leave-on care
• Skin-protecting polysaccharide for formulas targeting environmental stress and sensitive-skin comfort
• Suitable for serums, gels, creams, sheet masks, and oil-in-water emulsions
• Typical use level: 0.5–2.0% in leave-on skincare; higher levels Available upon request

Formulation Guidelines

Hydrate Yeast Polysaccharides fully in the water phase to obtain a uniform film-forming polysaccharide network and consistent viscosity contribution.

• Suggested Use Level: Typical 0.5–2.0% in leave-on skincare; higher levels Available upon request
• pH Range: Suggested 4.5–7.0 in finished aqueous systems
• Addition: Pre-disperse in water or glycerin to limit clumping; add to the water phase and allow full hydration; Suggested process temperature below 60°C
• Compatibility: Compatible with humectants, hyaluronic acid derivatives, and most O/W emulsions; avoid strong oxidizing agents and extreme pH
• Combine with Ceramide Np Powder for complementary lipid-matrix and polysaccharide-film barrier support.
