Amino Peptide

An elastin-derived peptide fraction

Amino Peptide is a commercial peptide solution that supplier notes describe as an elastin-derived peptide fraction. Elastin is one of the structural proteins of skin, and hydrolyzed elastin fractions have a long history in skin care as conditioning, film-forming ingredients. This listing is a water-compatible liquid for leave-on products.

What the documents confirm

The exact INCI and CAS for this SKU were not verified in open registries during our catalog review. Ask for the CoA before finalizing your label; elastin fractions may be declared under different INCI names depending on source and processing.

How it differs from synthetic peptides

Amino Peptide is a mixture of peptide fragments, not a defined synthetic sequence. It is not Acetyl Hexapeptide-8 and not Palmitoyl Tripeptide-5. Defined synthetic peptides carry a single INCI and CAS; protein-derived fractions behave more like a conditioning protein. If you need a defined firming peptide, look at Palmitoyl Pentapeptide-4 instead.

Formulating with Amino Peptide

Process

Add in the water phase during cool-down, below 40 °C, and mix gently. Protein-derived fractions can foam slightly under strong shear, so mix at low speed.

Bases

Creams, lotions, serums and conditioning gels all work. Protein fractions can add a smooth, slightly film-forming feel. Record pH and viscosity before and after addition.

Use level

Take the use level from the supplier documentation for your lot. Follow the supplier documentation.

Pairing with protein conditioners

For broader protein conditioning, our hydrolyzed proteins section carries collagen, wheat, soy and oat hydrolysates. Elastin fractions pair naturally with hydrolyzed collagen in firming-positioned creams.

Claims and labeling

Keep claims cosmetic: smoother, conditioned-feeling, supple-looking skin. If the source is animal-derived, the product does not fit vegan claims; confirm origin on the supplier documents.

Storage

Keep tightly closed, cool and away from light, and refrigerate opened material where practical.

Using elastin fractions in formulas

Protein-derived fractions like this one bring a smooth, slightly film-forming feel that many people describe as conditioning. In creams they can make the after-feel softer; in serums they add a light, supple finish. They also work in hair and body products where a conditioning protein is wanted, as long as the base is water-compatible.

Compatibility

Protein fractions are generally compatible with nonionic and mild anionic systems. In clear gels, check clarity after addition. Strong acids or very high temperatures can degrade proteins, so keep the finished pH near skin-neutral and add the fraction after cooling.

Documents

Ask for the CoA, the full INCI and origin information. Keep these with your product file so your label and claims match the documents.
