About

A synthetic/semi-synthetic protein hydrolysate modeled after thymus gland extracts, containing amino acids and peptide fragments similar to those found in thymic tissue. Used for its skin-conditioning properties in anti-aging formulations.

Protein Hydrolyzates, Thymus Gland, Synthetic (INCI: Synthetic Thymus Hydrolysate) refers to a chemically or enzymatically hydrolyzed protein preparation simulating the amino acid and peptide profile of thymus gland tissue. The 'synthetic' designation indicates it is produced via chemical synthesis rather than directly from animal thymus, avoiding concerns related to animal-derived ingredients. Under EU Regulation 1223/2009, synthetic peptides and amino acid mixtures are permitted cosmetic ingredients. No specific EU restrictions apply. The ingredient provides conditioning and film-forming properties on skin.

Skin benefits

  • Skin conditioning properties from amino acid and peptide content
  • May support skin repair through provision of amino acids for collagen synthesis
  • Film-forming effect that improves skin feel
  • Anti-aging claim support from thymus-derived growth factor analogy

Known concerns

  • Contains animal-derived amino acid profile simulated synthetically - no BSE/TSE concerns since synthetic
  • Peptide fragments may theoretically cause sensitivity in predisposed individuals
  • Limited specific toxicological data for this particular ingredient
