Saccharomyces Polypeptides

Product Description

Direct factory supply of high-purity Saccharomyces Polypeptides from standardized Saccharomyces cerevisiae fermentation. Controlled hydrolysis preserves peptide-rich fractions with batch COA traceability for cosmetic formulators.

Amino acid and oligopeptide constituents support keratinocyte metabolism, TEWL modulation, and antioxidant defense against ROS from UV exposure. The matrix performs as a natural humectant film former in aqueous bases.

Unlike single-sequence peptides, this INCI-listed complex delivers multi-peptide and amino-acid coverage in one active—suited for barrier essences, calming serums, and fermentation-forward anti-fatigue skincare lines.

Key Benefits & Applications

This yeast-fermented polypeptide complex addresses hydration, oxidative stress, and barrier resilience in modern aqueous skincare.

• Amino acid humectancy and deep moisture retention via natural film-forming oligopeptides in toners and essences.
• Antioxidant defense against UV- and pollution-induced free radicals through fermentation-derived peptide metabolites.
• Keratinocyte vitality and turnover support via amino acid cofactors linked to cellular energy pathways.
• Stratum corneum barrier conditioning and lipid-matrix compatibility in post-treatment calming formulations.
• Collagen matrix signaling support from low-molecular yeast peptides in anti-fatigue firming serums.

Formulation Guidelines

Typical cosmetic use levels and process notes for aqueous Saccharomyces Polypeptides in fermentation-forward lines.

• Recommended use level: 1–5% w/w in essences, serums, and barrier creams; up to 8% in ampoules (Typical).
• Add during cool-down below 45°C to preserve heat-sensitive peptide fractions.
• Compatible pH window 4.5–7.0; avoid strong oxidizers and high-level strong acids in one pot.
• Water-soluble; pre-dilute in humectant phase before incorporation into emulsions.
• Pairs well with glycols and hydro-alcoholic bases; patch-test with strong chelators at high use levels.
• Synergy: Layer Hyaluronic Acid beneath yeast polypeptides for stacked amino-acid humectancy in water-based essence toners.
