Palmitoyl Tripeptide-1, also known as Palmitoyl Oligopeptide, is a classic collagen-promoting signal peptide and a core active ingredient for root-cause anti-aging, firming and wrinkle-reducing skincare.

Cosmetic-grade Palmitoyl Tripeptide-1 is chemically synthesized in compliance with regulations. Plamed produces the ingredient via Solid Phase Peptide Synthesis (SPPS), stably supplying high-purity ≥98.0%; the internal control standard for active peptide content is ≥80.0%, with batch test values reaching up to 85.1%.

Chloride ions may derive from salt formation adjustment and neutralization during peptide manufacturing, existing in various forms in the system. Plamed has established a scientific chloride content control range, optimizing the industry’s conventional free hydrochloric acid detection index. Traditional hydrochloric acid content is calculated indirectly via chloride conversion, involving salt-form assumptions and conversion errors. Based on analysis of potential salt-forming sites of Palmitoyl Tripeptide-1, we set a reasonable control range with reference to the theoretical maximum salt-forming chloride content for batch stability management. This indicator is accurate and unambiguous, helping reduce formulation fluctuation risks, shorten formulation adjustment cycles, and improve formulation development efficiency and long-term finished product stability.
