Cosmetic Raw Material Trifluoroacetyl Tripeptide-2 PowderCAS 64577-63-5
Chemical name: Trifluoroacetyl Tripeptide-2
INCI name: Trifluoroacetyl Tripeptide-2
Alias: Anti-wrinkle tripeptide, firming peptide-2
CAS number:
Molecular weight: about 500-700 Da
Appearance: white to off-white freeze-dried powder
Solubility: Slightly soluble in water, easily soluble in polar solvents (such as propylene glycol, ethanol).
Trifluoroacetyl modification enhances fat solubility and improves transdermal absorption efficiency.
This peptide targets and regulates the skin cell signaling pathway to exert anti-wrinkle and firming effects, and is commonly found in high-end anti-aging skin care products.

Anti-wrinkle and firming:
Inhibit neuromuscular junction signal transmission (botulinum-like mechanism), reduce dynamic expression lines (such as crow's feet and forehead wrinkles).
Stimulate collagen regeneration:
Activate fibroblasts and promote the synthesis of type I collagen and elastin.
Improve skin elasticity:
Enhance the structural support of the dermis and improve relaxation and sagging.
Optimize transdermal absorption:
Trifluoroacetyl modification increases fat solubility and penetrates the stratum corneum directly to the dermis.
