This technology features a skin-whitening composition containing extracts and solvent fractions of Triglochin maritima, a halophyte native to the tidal flats of the West and South Seas. Intellectual property rights have been secured for three distinct applications: cosmetics, food products, and pharmaceutical compositions for skin pigmentation disorders.
Existing melanin-inhibiting agents have limitations: hydroquinone is restricted due to skin irritation and stability concerns, kojic acid has been linked to thyroid-related side effects, and ascorbic acid is prone to degradation by light and air, resulting in poor formulation stability. With hyperpigmentation rates rising due to climate change and environmental pollution, there is a critical shortage of safe, natural whitening ingredients.
Leveraging the ability of halophytes to accumulate bioactive substances in saline environments, this technology reduces both melanin content and tyrosinase activity, while also suppressing the expression of genes involved in melanin synthesis. It is applicable to functional whitening cosmetics, inner beauty products for pigmentation relief, and the development of tidal flat resources, allowing for the exclusive use of Triglochin maritima—an untapped halophyte—as a proprietary whitening ingredient.
This invention was developed with support from the Ministry of Education for the development of blue carbon biomass-based source materials and the establishment of a marine resource recycling platform.
