Oxaceprol

Oxaceprol (CAS 33996-33-7), also known by the trade name Jonctum and commercially as acetyl hydroxyproline, is a modified amino acid derivative used in pharmaceutical and cosmetic formulations. It functions as a humectant, antioxidant stabilizer, and pH-buffering agent, supporting both skin conditioning and active ingredient performance in finished products for various industries.

In pharmaceutical preparations, it has been developed as an active ingredient in anti-inflammatory and joint-support formulations, particularly for oral and topical dosage forms targeting connective tissue. Cosmetic formulators incorporate it into premium skincare products, such as serums, creams, and masks, where its moisture-retention capacity supports essential skin hydration claims.

Its buffering behavior helps stabilize pH-sensitive formulations, making it relevant for developers working with peptide-based or enzyme-active systems in modern laboratory settings. The compound also appears in functional topical preparations where collagen-pathway support is a desired positioning attribute for high-end personal care and dermatological brands.

This material is supplied as a white to off-white crystalline powder. It is available in pharmaceutical-grade specifications suited to drug product manufacturing and cosmetic-grade material. Buyers should confirm purity levels and documentation, including COA and relevant pharmacopoeial alignment, when sourcing for regulated end uses in global chemical markets.
