Mu-Conotoxin CnIIIC, Arginine/Lysine Polypeptide, Conotoxin Peptide

Product Description
This product is μ-Conotoxin-CnIIIC (also known as conotoxin polypeptide, conotoxin peptide, arginine lysine polypeptide, English name μ-Conotoxin-CnIIIC / XEP-018), with CAS No. 936616-33-0. It is a small-molecule polypeptide composed of 22 amino acids, originally discovered in the venom of tropical marine cone snails. Currently, it is mainly produced by polypeptide synthesis technology in industry. Its molecular formula is approximately C₉₂H₁₃₉N₃₅O₂₈S₆ and molecular weight about 2832. It normally appears as white to off-white powder with purity up to more than 98% (detected by HPLC). As a mature commercial polypeptide raw material, it can be supplied in different grades such as cosmetic grade and reagent grade according to applications. It is widely used in anti-wrinkle skincare products and scientific research, and is one of the well-known "botox-like" anti-wrinkle peptides in the cosmetic industry. The product should be stored in a sealed, light-proof, cool and dry place to guarantee stable quality within the shelf life.

Product Functions
μ-Conotoxin-CnIIIC works on a mechanism similar to botulinum toxin but milder: it targets the signal transmission between nerves and muscles, helping relieve excessive tension of facial muscles so as to smooth dynamic wrinkles formed by facial expressions (such as forehead lines, crow's feet and glabellar lines). Unlike injectable botulinum toxin, this ingredient is added into skincare products at a very low concentration. It is recognized for milder effects and a good safety profile, hence widely adopted in "topical anti-wrinkle" products. Meanwhile, as a selective research tool for sodium channels, it also carries important scientific research value in the physiological study of nerves and muscles.

Its specific functions can be summarized as follows:
Smooth dynamic wrinkles: help relax tense expression muscles and fade dynamic wrinkles including forehead lines and crow's feet;
Mild botox-like effect: similar mechanism to botulinum toxin but applied topically for gentler use;
Improve skin firmness: when used in skincare routines, help alleviate sagging facial contours;
Value as research tool: serve as a tool polypeptide for physiological research related to sodium channels;
Good formulation compatibility: compatible with various formulations such as serums, creams and facial masks.
