Creatine

Creatine (CAS 57-00-1, EC 200-306-6) is a naturally occurring nitrogenous compound found in vertebrate muscle tissue, also known under the names Kreatin, Neotine, Phosphagen, and NSC 8752. It carries no assigned E-code and is commercially produced as a synthetic monohydrate or anhydrous powder for industrial supply.

In personal care formulations, creatine functions as a skin and hair conditioner by supporting cellular energy metabolism in follicle and dermal cells, while its buffering capacity helps stabilize product pH within target ranges. It also acts as a humectant, drawing and retaining moisture in leave-on and rinse-off systems, and demonstrates mild antimicrobial activity relevant to preservation strategies.

Creatine is supplied in food-grade and cosmetic-grade forms, with quality benchmarks aligned to FCC and Ph.Eur. monograph standards where applicable. It falls under HS code 29252900 and is subject to REACH registration requirements for EU import and distribution. Packaging is typically available in multi-kilogram bags or fiber drums.
