Problems solved by technology

[0009] In addition, the problem to be solved by the present invention is to solve the problem that when serine or carnitine, which has an effect more excellent than that of conventional keratin exfoliation ingredients, is actually applied to a cosmetic formulation, the keratin exfoliation effect decreases. The problem

Embodiment 1

[0058] Embodiment 1: evaluation of exfoliation of pigskin cuticle

[0059] According to the existing clinical evaluation method, it takes a long time, and it is difficult to conduct all experiments of various concentrations and pH conditions of various raw materials. In addition, because it is difficult to conduct experiments on all conditions of the composition composed of various raw materials, it is emerging The necessity of non-clinical keratinization evaluation method.

[0060] Therefore, the present invention uses the keratin exfoliation evaluation method mentioned in Journal of the European Academy of Dermatology and Venereology, 2014, 28, 415-423. In detail, the pig skin was biopsied and the materials to be tested were added. Thereafter, the amount of detached cutin was measured with a cell counter, and the sample put into water alone was shown as a negative control (0%), and 10% gluconolactone pH4 was shown as a positive control (100%).

[0061] (1) The experimental...

Embodiment 2

[0099] Example 2: Evaluation Method for Enhancement of Cutin Replacement Based on DHA Staining Method

[0100] The DHA hair dyeing method for evaluating the cutin turnover rate was carried out on 10 healthy males aged 20 to 40 using the method mentioned in Dermatology 1993, 186, 133-137. Before coating the sample, measure the lower arm of the experimenter's arm, the color of the inner side of the upper arm with a colorimeter (Chromameter), then dip the dihydroxyacetone of 10% concentration of about 0.4ml ( Dihydroxy acetone: DHA), and stick it on the inner side of the upper and lower arms for 8 hours. After 48 hours, the color of the part colored brown by DHA was measured to compare the color difference with that before the sample was applied. Thereafter, the sample was applied twice a day, and the degree of daily fading was measured with a colorimeter at the same time to measure the time required to return to the original skin color. TT (Turnover Time) 100% refers to the ti...

Abstract

The present invention relates to a composition of a cosmetic material for increasing skin exfoliation, comprising an exfoliating agent and no polyol humectant or 10 wt% or less of the polyol humectantwith respect to the total weight of the composition, wherein the composition of the cosmetic material is selected such that the affinity of the exfoliating agent to keratin-binding proteins can be retained, and the exfoliation-increasing effect thus provided can be reliably achieved. Furthermore, the present invention provides the cosmetic material which does not cause irritation due to cosmeticmaterial, and in particular, allows exfoliating effects of serine or carnitine to remain excellent without a decrease in efficacy.

Description

technical field [0001] This application claims priority based on Korean application No. 10-2018-0083069 filed on July 17, 2018 and Korean application No. 10-2019-0063704 filed on May 30, 2019, the specification and drawings of the application All content disclosed in is cited in this application. [0002] The present invention relates to a cosmetic composition for enhancing skin exfoliation. Background technique [0003] The stratum corneum is the layer present at the outermost periphery of the skin, and is mainly composed of keratinocytes and a lipid layer of a lamellar structure including ceramide. The stratum corneum functions as a defense membrane capable of preventing internal water detachment and the like while exhibiting the effect of protecting from external substances. The normal stratum corneum has a thickness of about 15-20 layers, and desmosomes are decomposed by the action of serine protease activated from the outside of the stratum corneum, and eventually und...
