CASMN Receives Patent for a Brightening and Pigmentation-Care Composition (Translation)

CASMN received a Chinese invention patent for “A brightening and pigmentation-care composition, gel, preparation method and application”, patent number ZL 2024 1 0598208.1.

Composition and proposed mechanisms

The source describes a six-active combination including tranexamic acid, niacinamide and 4-butylresorcinol. The formulation rationale combines inhibition of melanin-related processes, modulation of melanosome transfer and antioxidant protection.

Formulation and manufacturing considerations

The article discusses controlled release, tolerability, gel-carrier stability and manufacturing consistency as development goals. Patent protection does not itself demonstrate absence of sensitisation, clinical efficacy or suitability for every user.

At publication, the company reported more than 70 patent applications and described microcrystal patches and hydrogels as potential carriers. References to pigmentation concerns describe development interests; a patent is not a special-cosmetics registration, medical approval or a guarantee of treatment results.
