Abstract

The invention belongs to the field of biochemistry, and particularly relates to a novel nano tranexamic acid targeting preparation and a preparation method thereof. The novel nano tranexamic acid targeting preparation comprises the following raw materials by weight: 5%-30% of a nano lipid targeting material; 2%-20% of tranexamic acid; 2%-10% of an emulsifier; 0.1%-1% of a thickening agent; 0.1%-1% of papain; 0.01%-10% of an effective additive; and the balance of deionized water. The tranexamic acid disclosed by the invention is short in service cycle and high in targeting speed, and the raw materials have more comfortable skin feeling and smaller emulsification particle size, so that the finally obtained nano preparation is more obvious in targeting effect.

Description

technical field [0001] The invention belongs to the field of biochemistry, and in particular relates to a novel nanometer tranexamic acid targeting preparation and a preparation method thereof. Background technique [0002] Melanin is a major factor that determines the color of human skin. Melanin can effectively protect the skin against skin photodamage and photoaging caused by ultraviolet radiation, while excessive accumulation and uneven distribution of melanin can lead to dull skin, chloasma, freckles and age spots generation. Tyrosinase is the main rate-limiting enzyme for melanin synthesis, so regulating the activity of tyrosinase is currently the most researched and applied approach for whitening and lightening spots. Tranexamic acid and tyrosine have similar chemical structures, and they compete to bind tyrosinase, thereby interfering with the normal formation of melanin. Tranexamic acid can also achieve the effect of brightening the skin in the following ways: the...
