Embodiment 1

[0036] This embodiment provides a composition containing hydroxy acid and its preparation method.

[0037] Wherein, the composition containing hydroxy acid is based on 100% of its total mass, and includes the following components: 80% glycolic acid, 18% salicylic acid and 2% papain, wherein α-hydroxy acid (glycolic acid) The mass ratio to β-hydroxy acid (salicylic acid) is 4.4:1;

[0038] The preparation method is as follows:

[0039] Glycolic acid, salicylic acid and papain were mixed for 3 minutes at a stirring speed of 500 rpm under the condition of 30° C. to obtain the composition containing hydroxy acid.

Embodiment 2

[0041] This embodiment provides a composition containing hydroxy acid and its preparation method.

[0042] Wherein, the composition containing hydroxy acid is based on 100% of its total mass, and includes the following components: 75% malic acid, 20% salicylic acid and 5% papain, wherein α-hydroxy acid (malic acid) The mass ratio to β-hydroxy acid (salicylic acid) is 3.5:1;

[0043] The preparation method is as follows:

[0044] Malic acid, salicylic acid and papain were mixed for 5 minutes at a stirring speed of 300 rpm under the condition of 40° C. to obtain the composition containing hydroxy acid.

Embodiment 3

[0046] This embodiment provides a composition containing hydroxy acid and its preparation method.

[0047] Wherein, the composition containing hydroxyacid is based on its total mass as 100%, including the following components: 60% lactic acid, 30% salicylic acid and 10% bromelain, wherein α-hydroxyacid (lactic acid) and β The mass ratio of -hydroxyacid (salicylic acid) is 2:1;

[0048] The preparation method is as follows:

[0049] Lactic acid, salicylic acid and bromelain were mixed at a stirring speed of 600 rpm for 8 minutes under the condition of 50° C. to obtain the composition containing hydroxy acid.

Abstract

The invention provides a hydroxy acid-contained composition as well as a preparation method and application thereof. The hydroxy acid-contained composition is prepared from the following components including alpha-hydroxy acid, beta-hydroxy acid and proteases. For the hydroxy acid-contained composition provided by the invention, the alpha-hydroxy acid and the beta-hydroxy acid are specifically selected and are compounded with the protease, and the three components can cooperate with each other to achieve synergistic interaction, so that the finally obtained composition has the effect of removing keratoderma and can further have the comprehensive repairing effects of lowering skin pigmentation, brightening skin and improving skin color and the skin roughness. In addition, as all the components are derived from natural fruits, the hydroxy acid-contained composition can obviously lower potential stimulation to the skin without influencing the capacity of stimulating regeneration of cellsand is wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a composition containing hydroxy acid and its preparation method and application. Background technique [0002] With the growth of age or the influence of external physical and chemical environmental conditions (excessive sun exposure or exposure, etc.), human skin will appear aging phenomenon to varying degrees, and the substances between fibers will change, especially the moisture will decrease, and the skin will become dry and dry. Loose, rough, and even acne, black warts, keratotic eczema and other skin diseases. [0003] In order to alleviate the above skin problems, fruit acids are added to many cosmetics. AHAs are a class of naturally occurring non-toxic substances, most of which are organic acids extracted from various fruits, sugar cane, and yoghurt. Fruit acid has a simple molecular structure, small molecular weight, non-toxic and odorless, strong permeability, can ...
