Palmitoyl Tripeptide-38 Solution

A lipopeptide made water-friendly

A palmitoylated peptide normally resists water because of its fatty chain. This concentrate gets around that with hydroxypropyl cyclodextrin, a ring-shaped sugar molecule that hosts the lipophilic part and lets the peptide disperse evenly in an aqueous base. The outcome is a transparent liquid that pours straight into gels and essences, sold to formulators as a cosmetic raw material.

Full INCI declaration

Palmitoyl Tripeptide-38, Hydroxypropyl Cyclodextrin, Aqua, Caprylyl Glycol, Ethylhexylglycerin, Glycerin, Trehalose. Many competing liquids list only glycerin, water and cyclodextrin and leave preservation to you; this one adds trehalose for humectancy and peptide protection and a caprylyl glycol plus ethylhexylglycerin pair that is free of parabens and phenoxyethanol. Lot data appear on the CoA.

Why the carrier matters

Clarity in transparent formats

Since the cyclodextrin complex stays in solution, this grade suits crystal-clear serums, toners, essences and hydrogel patches where any haze would show.

Related grades

Buyers comparing trade-name options can read Palmitoyl Tripeptide-38. A copper-free signal peptide that pairs well is Tripeptide-1 Solution, and a comfort peptide for sensitive-skin lines is Palmitoyl Tripeptide-8 Solution. More water-based actives sit within the solution-form peptides range.

Dosing and process

US suppliers of this solution type cite 0.5 to 10% of the finished formula, from light lotions at the bottom of the range to concentrated serums at the top; confirm against your lot CoA. It dissolves in water but not in oil, so stir it into the aqueous phase or the cooled emulsion below 40 °C. A finished pH of roughly 4.5 to 6 suits both the peptide and the preservative pair.

Compatibility

Cyclodextrins can host other lipophilic molecules, so add fragrance and oil-soluble actives after the peptide and check clarity. Avoid strong oxidizers and long heating.

Bottles

Available in 1, 2, 4, 8 and 16 oz sizes, shipped from Florida with a CoA and a TDS on request. Close tightly, keep cool and shaded, and reseal right after use.
