The invention belongs to the field of cosmetics, and relates to a composition with an acne removing effect, and a preparation method and application thereof.

Background

Acne (whelk) is a chronic inflammatory dermatosis of a pilosebaceous unit, and is shown by the combined investigation of the national dermatosis association and the national association of teenagers: the incidence of the acne in China is on the trend of increasing year by year, and more than 80% of people can encounter the acne in different degrees. Wherein the number of acne patients of middle school students is 2.94 hundred million, the number of acne patients of college students is 1.33 hundred million, the number of acne patients of office white collar of over 25 years old is more than 1.27 hundred million, and the total of three majority of people is more than 5.5 hundred million. Acne seriously affects the appearance and confidence of people and has negative influence on the work and life of people, so the acne removal is one of the research focuses of cosmetics

The occurrence of whelk is closely related to factors such as excessive sebum secretion, blockage of pilosebaceous ducts, bacterial infection, inflammatory reaction and the like. A variety of microorganisms are present in hair follicles, and when Propionibacterium acnes proliferates in large quantities, the lipase produced by Propionibacterium acnes breaks down sebum to produce free fatty acids, while chemotactic inflammatory cells and mediators, inducing and exacerbating the inflammatory response. Therefore, propionibacterium acnes is considered as a main bacterium for producing acnes, and most of traditional acne-removing products achieve the aim of removing acnes by killing propionibacterium acnes.

However, researches show that the propionibacterium acnes also exists on the skin of healthy people, if the propionibacterium acnes is killed once, the ecological system of microorganisms on the skin epidermis is unbalanced, the problem of the acne cannot be solved fundamentally, and certain microorganisms can resist the drug resistance of products to cause more skin problems.

Test example 1 competitive inhibition test for Propionibacterium acnes

In vitro testing:

examples 1-3 and comparative examples 1-14 were applied to skin microorganisms cultured in vitro to verify their competitive inhibitory effect on acne bacilli.

The test method is as follows:

(1) Respectively inoculating Staphylococcus epidermidis to nutrient broth culture medium (pharmacopeia), and inoculating Propionibacterium acnes to GAM culture solution.

(2) 10ml of each culture broth, 9 portions each, were added with 0.1ml of the compositions of examples 1-3 and comparative examples 1-6, respectively, and 0.1ml of deionized water (blank).

(3) Then, the staphylococcus epidermidis is aerobically cultured at 37 ℃ for 24h, and the propionibacterium acnes is anaerobically cultured at 37 ℃ for 48 h.

(4) The number of each strain in the culture solution before and after the culture was determined by the dilution plate method. The measurement results are shown in table 1.

TABLE 1 comparison of skin microbial counts before and after incubation (cfu/ml)

As can be seen from table 1, the lactobacillus fermentation product, the leuconostoc/radish root fermentation product filtrate, the white willow bark extract and the saccharide isomer in the mixture ratio range of the invention can effectively and competitively inhibit the proliferation of acne bacillus and promote the proliferation of beneficial bacteria (represented by staphylococcus epidermidis). Comparing example 1 with comparative examples 1-2, it can be seen that the addition of too much or too little lactobacillus fermentation product or leuconostoc/radish root fermentation product filtrate affects the competitive inhibition of the propagation of acnes; comparing example 1 with comparative examples 3-6, it can be seen that the competitive inhibition of the single component on the acne bacillus is not obvious, and the synergistic effect can be effectively achieved only under the condition of the component ratios, so that the proliferation of the acne bacillus can be effectively and competitively inhibited. Comparing example 1 with comparative examples 7-10, it can be seen that the absence of any component in the present invention affects the proliferation of beneficial bacteria (represented by staphylococcus epidermidis), and has no obvious effect on the competitive inhibition of the proliferation of acne bacillus, and each component supplements each other and cannot be absent. Comparing example 1 with comparative examples 11 to 14, it can be seen that any of the components of the present invention was replaced with a similar substance, which resulted far less than example 1, and that any of the components of the present invention was not replaceable. Comprehensively, the lactobacillus fermentation product, the leuconostoc/radish root fermentation product filtrate, the white willow bark extract and the saccharide isomer supplement each other, are all indispensible and irreplaceable, can effectively competitively inhibit the proliferation of acne bacillus within a mixture ratio range, and promote the proliferation of beneficial bacteria (represented by staphylococcus epidermidis).
