Cosmetic Peptide Solutions for Formulators

84 cosmetic peptides supplied as ready liquids — Argireline, SNAP-8, Leuphasyl, Matrixyl 3000, GHK-Cu, Eyeseryl, EyeLiss, Capixyl and Myristoyl Pentapeptide-17 among them — that you add straight to the cool-down phase instead of weighing and dissolving a powder. Each card gives the INCI and the CAS number of the active, or says Mixture or N/A where no registry number is verified. Every solution is sold from a 10 mL sample up to a 1-gallon pack, so you can test and scale the same SKU.

Solution or powder?

A solution is the peptide pre-dissolved in water, glycerin or butylene glycol, sometimes with a preservative; you add it in cool-down. A peptide powder is the neat sequence: you weigh it, dissolve it and set the concentration yourself. Trade blends — Matrixyl 3000, EyeLiss, Haloxyl, Capixyl, Argirelox — are sold here only as solutions.

Copper peptides (GHK-Cu / Copper Tripeptide-1)

Copper Tripeptide-1 (GHK-Cu, CAS 89030-95-5) under three SKUs from different source packs. Copper peptides are pH-sensitive and can be destabilized by strong chelators such as EDTA.

Eye-contour peptides (Eyeseryl, EyeLiss, Haloxyl)

Acetyl Tetrapeptide-5 (Eyeseryl, three SKUs), EyeLiss (Hesperidin Methyl Chalcone, Dipeptide-2, Palmitoyl Tetrapeptide-7), Dipeptide-2 alone and Haloxyl (Chrysin, N-Hydroxysuccinimide, Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7) for under-eye gels aimed at the look of puffiness and dark circles.

Capixyl (Acetyl Tetrapeptide-3 with red clover flower extract), Acetyl Tetrapeptide-3 as a solution or a dry powder, Biotinoyl Tripeptide-1 and liposomal Tripeptide-1 complexes for scalp serums. In the US, a claim to grow hair or stop hair loss makes the product a drug; keep claims to the look of fuller hair.

Lash and brow peptides (Myristoyl Pentapeptide-17)

Myristoyl Pentapeptide-17 (CAS 959610-30-1) under three names — XLash, Eye Lash Penta Peptide and the INCI-named listing — plus Myristoyl Hexapeptide-16 (Eye Lash Hexa Peptide).

Tone, radiance and signaling peptides (Nonapeptide-1, EGF, Oligopeptides)

Nonapeptide-1 (alone and in Dawnergy), X50 Pure White and Acetyl Hexapeptide-1 (Melitan) for tone and radiance formulas; sh-Oligopeptide-1 (EGF), SH-Decapeptide-9 and Oligopeptides-1, -2 and -8 for renewal-look serums. Some oligopeptide lots carry the plain INCI and some the sh- INCI, so check which one is on the CoA.

Body-contour, marine and botanical peptide solutions

Acetyl Hexapeptide-38 (Adifyline) for volume-look formulas, Pepti-slim for body-contour products, caviar, marine, pea and elastin peptide solutions, and a ready multi-peptide serum base. Most of these trade grades have no verified sequence or CAS, so their cards say “confirm on CoA” instead of listing one.

Formulating with peptide solutions

  1. Add the solution in cool-down, below 40 °C / 104 °F, after the emulsion or gel is built.
  2. Dose by weight, not volume: glycerin-rich bases are noticeably denser than water (pure glycerin is 1.26 g/mL).

Peptide solutions FAQ

What sizes are peptide solutions sold in?

Every peptide solution is sold in seven sizes: 10 mL, 1 oz (30 mL), 4 oz (118 mL), 8 oz (237 mL), 16 oz (473 mL), 32 oz (946 mL) and 1 gallon (3.78 L). The price on the grid is the 10 mL size. For more than a gallon, or for delivery outside the US, use the quote form.

Why is the CAS number "Mixture" or "N/A" on some cards?

Trade blends such as Matrixyl 3000, EyeLiss and Capixyl contain several registered substances, so the card says Mixture and lists the component CAS numbers that are published. Some sequences and trade grades have no CAS number we could verify; those cards say N/A instead of showing a number we cannot source.

Why don’t the cards give a use percentage?

Peptide content differs between grades and suppliers, so a percentage that is right for one lot can be wrong for another. Use the level on the supplier CoA or technical data sheet for the lot you receive.

Why are some peptides listed under several SKUs?

Acetyl Tetrapeptide-5 (Eyeseryl), Capixyl, Copper Tripeptide-1 and Myristoyl Pentapeptide-17 each appear under three SKUs that come from different supplier source packs. The INCI is the same; the peptide content can differ, so compare the CoAs before switching SKUs in an existing formula.

Are the solutions preserved?

Some are: Argireline Amplified lists Sodium Benzoate, and Fensebiome, Inyline Solution, Dawnergy and Argirelox list Caprylyl Glycol. Others are glycerin or butylene glycol bases. The INCI on each card shows which. Either way, preservative efficacy of the finished formula has to be tested.
