Abstract

The invention relates to the technical field of cosmetics, in particular to a method for improving compounding stability of potassium 2-hydroxy-4-methoxybenzoate and tranexamic acid. A light protecting agent is added to a potassium 2-hydroxy-4-methoxybenzoate and tranexamic acid compounding system, and the pH value of the system is controlled to 4.5-6.5. The light protecting agent is added, and the pH value of products is regulated, so that the problems that after being compounded, the potassium 2-hydroxy-4-methoxybenzoate and the tranexamic acid compound can generate the phenomenon of color changes after illumination is solved, the appearance and the color stability of products are effectively protected, and the usage amount of the potassium 2-hydroxy-4-methoxybenzoate and the usage amount of the tranexamic acid can achieve relative high dosage. The appearance and the color stability of prepared products are obviously improved. Within a long time, obvious color changes are not generated, test proves that the method is effective on delaying a photochemistry reaction due to interaction of the potassium 2-hydroxy-4-methoxybenzoate and the tranexamic acid, and the products can maintain durable stability, so that consumers can obtain good using experience.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a method for improving the compound stability of potassium methoxysalicylate and tranexamic acid. Background technique [0002] The cosmetics market is becoming more and more mature, and women who love beauty pay more and more attention to their own image. As an important cosmetic category, whitening is favored by the majority of women and occupies a considerable share in the market. Various whitening ingredients added to whitening products are also changing with each passing day. Potassium methoxysalicylate (4MSK), as a relatively new whitening ingredient, has the effect of inhibiting melanin production and has excellent defense against pigmentation caused by ultraviolet rays Effect, its whitening effect has been recognized by consumers. However, the effect of a single whitening raw material is often not as remarkable as the combined use of two or more whitening raw materials...
