Embodiment 1 and 2 and comparative example 1-4

[0038] According to the compositions and contents shown in Table 2 below, the cosmetic compositions of Examples 1 and 2 and Comparative Examples 1-4 were prepared. Specifically, components 1-7 were mixed with each other and dissolved at 70°C to obtain an aqueous phase. Meanwhile, components 10-16 were dissolved at 70°C to obtain an oil phase. The oil phase was added to the water phase, and the mixture was stirred with a homogenizer (Tokushu Kika Kogyo, Japan) to prepare an emulsion. Components 17 and 18 were then added to the emulsion to perfume and thicken the emulsion. The mixture was defoamed and then cooled to room temperature, thereby preparing the cosmetic compositions of Examples 1 and 2 and Comparative Examples 1-4.

Abstract

The present invention relates to an inhibitor for melanin which contains tranexamic acid and niacinamide as active ingredients for inhibiting the formation of melanin cells in the skin, and a cosmetic composition containing the inhibitor for melanin as an active ingredient for relieving liver spots, blemishes, freckles and inflammatory hyperpigmentation, improving skin tone and texture, and skin whitening.

Description

technical field [0001] The present invention relates to an inhibitor of melanin production, which contains as active ingredients tranexamic acid (tranexamic acid) and nicotinamide which inhibit the formation of skin melanocytes, and a cosmetic composition containing melanin production inhibitor As an active ingredient, it has the effect of reducing melasma, acne, freckles and post-inflammatory hyperpigmentation, improving skin tone and texture, and skin whitening. Background technique [0002] The skin has physical and chemical factors that resist ultraviolet rays and has properties that reduce skin damage caused by various photochemical reactions. The stratum corneum reflects and diffuses UV rays so that the energy of the UV rays is attenuated. In addition, melanin, SOD (superoxide dismutase) and other antioxidant components that absorb ultraviolet rays are widely distributed in the skin, attenuating the energy of ultraviolet rays, or eliminating reactive oxygen species (r...
