Mu‑Conotoxin CnIIIC

What Mu-Conotoxin CnIIIC is

Mu-Conotoxin CnIIIC is a peptide originally identified in the venom of Conus consors, a marine cone snail. The cosmetic ingredient is a synthetic version: the amino acid sequence is built in a laboratory, and no snail or venom is involved. In skin care it belongs to the premium end of the expression-line category, next to better-known peptides such as Acetyl Hexapeptide-8 and Dipeptide Diaminobutyroyl Benzylamide Diacetate Powder. This page sells it as a fine powder by the gram. The full INCI, purity and use level are printed on the CoA for each lot.

Properties

The ingredient is positioned in supplier material as a cosmetic biomimetic for expression lines, with a fast, visible smoothing story. As a fine powder, it is weighed in very small amounts and dissolves or disperses into the water phase. Its unusual origin story and the high purity of synthetic peptides make it a strong hero ingredient for premium and professional brands. Keep claims about appearance and avoid any comparison with injectable procedures.

Applications

Our record lists appearance-focused cosmetic cosmetics, wrinkle-smoothing creams and serums, premium and professional cosmetics, specialized products for expression lines, peptide concentrates in ampoules and creams for the eye area. Practical examples are single-dose ampoules, eye contour serums, forehead fluids and luxury night creams. Brands often combine it with Dipeptide Diaminobutyroyl Benzylamide Diacetate Powder or Pentapeptide-18 Powder in a multi-peptide product. Explore more in our peptides catalog.

How to dissolve and add it

Weigh the powder on a balance reading to 0.001 g or better, ideally preparing a stock solution for daily work. Dissolve or disperse it in a small amount of distilled water, then add it to the cooled batch below 40 °C with gentle mixing. Avoid reheating. Follow the CoA for the use level and keep the finished pH in a mild range.

Working with high-value peptides

With premium peptides, small losses matter. Weigh onto anti-static weighing paper or directly into the dissolving beaker, rinse every vessel with a little water from the batch and add the rinse back. Keep the powder container closed except when weighing, since fine powders pick up moisture. Record lot numbers on every batch sheet and keep a retained sample of each finished batch.

Compatibility

Synthetic expression-line peptides generally work with glycerin, hyaluronic acid, panthenol, niacinamide, caffeine and other peptides, in gels, serums and oil-in-water emulsions. Avoid strong acids, strong bases, oxidizers and long heating. Copper peptides belong in a separate product. Add each peptide one at a time.

Phase A: distilled water 89.40 g, glycerin 3.00 g, propanediol 2.00 g, hydroxyethylcellulose 0.60 g; hydrate until clear. Phase B below 40 °C: Mu-Conotoxin CnIIIC at the level on the CoA, here 0.01 g, dissolved in distilled water 1.00 g; Dipeptide Diaminobutyroyl Benzylamide Diacetate Powder 0.02 g dissolved in distilled water 1.00 g; panthenol 1.00 g; sodium hyaluronate 0.10 g predissolved. Phase C: eye-safe preservative 0.90 g, cucumber extract 0.97 g. Mix gently, adjust pH to about 6.0 and fill into single-dose vials.

Record the lot number of Mu‑Conotoxin CnIIIC in your batch log so every production run can be traced back to its certificate of analysis.

Storage

Keep the powder sealed, cool and dry, away from light and humidity; refrigeration is helpful. Let it reach room temperature before opening. Ships from Florida in gram packs.
