Composition for improving skin color and whitening cosmetic

Abstract

The invention discloses a composition for improving skin color and a whitening cosmetic. The composition comprises tranexamic acid, acetyl chitosamine and beta-nicotinamide mononucleotide. The tranexamic acid, the acetyl chitosamine and the beta-nicotinamide mononucleotide are compounded, the beta-nicotinamide mononucleotide is combined with the tranexamic acid and the acetyl chitosamine, pigmentation caused by ultraviolet rays or other skin irritation can be inhibited, and skin pigmented spots related to pigmentation are effectively prevented or improved. The acetyl chitosamine can improve transdermal absorption of effective components such as the tranexamic acid and the beta-nicotinamide mononucleotide, has a whitening effect, and can achieve a synergistic whitening effect when being used together with the tranexamic acid and the beta-nicotinamide mononucleotide, so that the tranexamic acid, the acetyl chitosamine and the beta-nicotinamide mononucleotide can achieve whitening and brightening effects at a low concentration, and are stable, safe and non-irritant.

Description

technical field

[0001] The invention relates to a composition for improving skin color and a whitening cosmetic comprising the composition, belonging to the technical field of cosmetics. Background technique

[0002] When the skin is exposed to ultraviolet rays, it produces melanin to protect skin cells from ultraviolet rays. The melanin produced absorbs UV rays, preventing them from penetrating deep into the skin and causing damage. Although melanin protects skin cells, it darkens the skin, and when produced in excess, melanin deposits on the skin causing pigment spots and freckles, reducing the aesthetic appearance. Fair skin has always been the pursuit of beauty-loving women, so natural whitening products are sought after by many users. At present, there are many whitening products on the market. Common whitening ingredients such as vitamin C, glutathione, resveratrol, etc. are unstable in the system, and are prone to discoloration and inactivation and are ineffective; ...

Examples

Embodiment 1

[0035] Prepare the whitening muscle base liquid, the preparation process is as follows:

[0036] (1) Weigh each raw material according to the formula in Table 1.

[0037] (2) After weighing and mixing the conditioner raw materials, heat to 50-70°C for later use.

[0038] (3) After weighing and mixing water, whitening agent, humectant, thickener, emulsifier, and stabilizer raw materials, heat to 50-70°C for later use.

[0039] (4) Slowly add the mixed solution obtained in step (2) into the mixed solution obtained in step (3) at a temperature of 50-70°C, set at 2000-3000rpm, homogenize for 8-15min, vacuumize and exhaust Bubbles, adjust the pH value with a pH value regulator, and the pH value is controlled within the range of 6.0-7.5.

[0040] (5) When the temperature drops to 40°C or below, add β-nicotinamide mononucleotide to ensure its activity.

[0041] Each raw material and its content are shown in Table 1.

[0042]

Embodiment 2-8

[0044] The whitening skin base solution was prepared according to the formula and method of Example 1, except that the contents of tranexamic acid, acetylglucosamine and β-nicotinamide mononucleotide were changed, as shown in Table 2.
