Cysteamine hydrochloride

Cysteamine hydrochloride from Hangzhou King Techina Feed Co., Ltd. is a microencapsulated compound designed for enhanced stability and bioavailability in formulations. The supplier’s version leverages microcapsule technology to improve absorption, a critical factor for its effectiveness in dermatological and pharmaceutical applications. This grade is suitable for use in cosmetics, particularly in products targeting hyperpigmentation and skin lightening.

The active ingredient is typically supplied as a white to off-white crystalline powder with a molecular formula of C2H8ClNS and a molecular weight of 113.61 g/mol. Standard purity levels for pharmaceutical-grade cysteamine hydrochloride exceed 98%, with residual solvents and heavy metals controlled to pharmacopoeial limits. Microencapsulation often uses polymer matrices like ethyl cellulose or PMMA to protect the compound from degradation in oxidative or humid environments.

This compound is primarily used in topical formulations such as creams, serums, and lotions for treating pigmentation disorders like melasma and vitiligo. Buyers in the cosmetics and pharmaceutical sectors prioritise suppliers with documented stability data and compliance with USP, EP, or JP monographs. For bulk sourcing, confirm the supplier’s ability to provide certificates of analysis, GMP compliance, and stability test reports for the microencapsulated form.
