AC Collagen Prepeptide PF

AC Collagen Prepeptide PF and Tripeptide-29

AC Collagen Prepeptide PF is a clear, thick liquid peptide made in Spain. Its INCI is Tripeptide-29, CAS 92113-31-0. Tripeptide-29 is a very small collagen-type peptide; the supplier gives a molecular weight of about 285 daltons and describes it as plant-derived. It dissolves in water, works between pH 4.0 and 7.0 and is used at only 0.1 to 1%. The smallest pack is 0.25 oz.

Why a small collagen peptide

Collagen itself is a very large protein. Short collagen-type peptides such as Tripeptide-29 are easy to dissolve and easy to dose, and the low molecular weight is one of the main points the supplier highlights. In product language, it supports a collagen care story without the heavy, sticky feel of large proteins.

What it does

The supplier describes it as a smoothing and firming peptide. Finished products help skin look smoother and more refined, support a firmer, more elastic look and help with the look of fine lines linked to dryness. A strengthening story for hair care is mentioned as well.

The dose ladder

About 0.1% works as an add-on in salon care. Products used after professional skin services use 0.3 to 0.7%. Products for more elastic looking skin use 0.5%. Age care serums, boosters and activators use 1%. Because the level is low, the peptide stays economical even in premium serums.

Processing and partners

Add it to the water phase or at cool-down and keep the finished pH between 4.0 and 7.0. Pair it with hyaluronic acid liquid for moisture and with palmitoyl pentapeptide-4 for a second peptide. Collagene Vegetale adds a plant collagen-style film. More peptides are in our peptide solutions section.
