Yeast Amino Acids

Product Description

Yeast Amino Acids from Green Stone Swiss are produced by controlled hydrolysis of yeast protein, then purified into a high-purity free amino acid concentrate for cosmetic bulk supply. Direct factory production keeps color, solubility, and amino acid distribution consistent from lot to lot, with GMP-aligned release, batch COA, TDS, and free samples for incoming QC and formulation trials.

According to CosIng, Yeast Amino Acids are the amino acids derived from yeast and function as a humectant, helping retain moisture in the product during use and on skin. The mixed residues behave like NMF amino acids in the stratum corneum: polar side chains bind water and support a hydrated, flexible surface feel without a heavy occlusive film. Typical profiles include glycine, alanine, proline, and serine; because this is a multi-component concentrate rather than a single molecule, assay values are confirmed on the batch COA.

Brands specifying water-light hydration in toners, essences, serums, gel-creams, and sheet masks use Yeast Amino Acids as an NMF-aligned humectant that is freely water-soluble and generally stable in aqueous solution. GSS factory-direct supply supports scale-up from sample to production with technical documentation and reliable replenishment.

Key Benefits & Applications

Yeast Amino Acids is a CosIng-listed humectant used as an NMF-aligned hydration active in professional aqueous and emulsion systems.

• Binds water through polar amino acid residues to support humectancy in formula and on skin
• Supplies NMF-relevant free amino acids (Typical: glycine, alanine, proline, serine) for stratum corneum hydration
• Supports TEWL control and barrier comfort in water-light leave-on textures (Typical)
• Compatible with toners, essences, serums, gel-creams, sheet masks, and hydrating emulsions
• Stable in aqueous solution with broad formulation compatibility versus polymeric film formers
• Typical use level: 0.5–5.0% in final formulation

Formulation Guidelines

Use these process notes to keep Yeast Amino Acids fully dissolved and functionally stable in cosmetic systems.

• Suggested Use Level: Typical 0.5–5.0% in final formulation
• pH Range: Suggested 4.0–7.5; avoid prolonged strongly alkaline conditions
• Addition: Predissolve in the water phase; add during cool-down below 45°C (Typical)
• Compatibility: Compatible with hyaluronates, polyglutamic acid, glycerin, and panthenol; avoid strong oxidizing agents
• Combine with Sodium Hyaluronate Crosspolymer for complementary NMF-style humectancy plus polymeric water binding.
