Problems solved by technology

[0003] However, the properties of retinol and retinal are very unstable, very sensitive to light, heat, oxygen and heavy metals, and the suitable pH range is narrow, so there are many limitations in application
Moreover, there is phototoxicity, which is easily stimulated by ultraviolet rays to cause oxidation and dissimilation reactions, resulting in free radicals
Although the various esters of retinol are better than retinol and retinal in terms of stability, their metabolic pathways on the skin are much longer than those of retinol and retinal, and their efficacy is very weak, and there is no guarantee that they will be completely free Phototoxicity

preparation example Construction

[0100] In the present invention, the preparation method of the cosmetic composition can be a conventional preparation method in the art, preferably, the method comprises the following steps:

[0101] (1) Mix the components of phase A to obtain material a;

[0102] (2) At 70-75°C, add the components of phase B to the water in phase B, then add material a, and mix to obtain material b;

[0103] (3) Under the condition of 70-75°C, mix the components of phase C to obtain material c, then add material c to material b, and mix to obtain material d;

[0104] (4) After reducing the temperature of material d to 40-45° C., add phase D and phase E, mix and adjust the pH to 5.7-6 to obtain a cosmetic composition.

[0105] Wherein, the order and method of adding the components of phase A are not particularly limited, as long as the components of phase A can be dissolved to obtain material a in a solution state. The mixing temperature is not particularly limited, for example, it can be at...

Embodiment 1- Embodiment 6

[0124] This embodiment is used to illustrate the cosmetic composition of the present invention

[0125] According to formulas R1-R6 in Table 1, essence milks A1-A6 were prepared as follows.

[0126] The method comprises: mixing and uniformly dispersing the components of phase A to obtain material a;

[0127] (2) At 75°C, add the components of phase B to the water in phase B, then add material a, homogenize at 2500 rpm for 5 minutes, stir for 10 minutes to dissolve, and obtain material b;

[0128] (3) At 75°C, add jojoba oil, squalane, olive oil emulsifying wax and dextrin palmitate in phase C to the container, stir well, then add the remaining components of phase C , after stirring, the material c was obtained, and then the material c was added to the material b and homogenized for 15 minutes, and then stirred for 30 minutes to obtain the material d;

[0129] (4) Reduce the temperature of the emulsification pot containing material d to 45°C and set it aside;

[0130] (5) Ta...

Embodiment 7

[0136] This embodiment is used to illustrate the cosmetic composition of the present invention

[0137] Essence milk R7 was prepared according to the formula R1 and method described in Example 1, except that 0.6 g of tocopheryl acetate and 0.5 g of rosemary extract were used instead of 0.5 g of lipoic acid and 3-o-ethyl ascorbic acid 1g and 0.6g of tocotrienol to prepare essence milk R7.

Abstract

The invention relates to the field of cosmetics, in particular to a composition, application thereof, a cosmetic composition and a preparation method of the cosmetic composition. The composition comprises a hydroxypinacolone retinoate and retinyl retinoate. The hydroxypinacolone retinoate, the retinyl retinoate, hydroxypropyl tetrahydropyrantriol, nicotinamide, tocotrienol, 3-o-ethyl ascorbic acidand lipoic acid are synergistically compounded to obtain more excellent oxidation resistance, so that the composition is higher in mildness and stability. The cosmetic composition prepared from the composition provided by the invention has the advantages of small irritation, high skin friendliness, high stability, good transdermal absorption, high utilization rate, high efficiency, mildness and better anti-aging activity than traditional retinol, and the anti-aging and anti-oxidation effects of the cosmetic composition can be further improved under the optimal condition.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a composition and its application, a cosmetic composition and a method for preparing the cosmetic composition. Background technique [0002] Most of the core functional ingredients of anti-aging products currently on the market are derivatives of vitamin A: such as retinol, retinal, hydrogenated retinol and retinyl esters (for example, retinyl acetate, retinal Retinyl Propionate, Retinyl Palmitate, and Retinyl Linoleate). [0003] However, retinol and retinal are very unstable in nature, very sensitive to light, heat, oxygen and heavy metals, and have a narrow pH range, so there are many limitations in application. Moreover, there is phototoxicity, and it is easily excited by ultraviolet rays to undergo oxidation and dissimilation reactions, and generate free radicals. Although the various esters of retinol are better than retinol and retinal in terms of stability, their metabolic path...
