Description

Technical Field

[0001] This invention relates to the field of cosmetic raw material technology, and in particular to a compound skin care active raw material and its preparation method. Background Technology

[0002] Currently, most skincare ingredients on the market are single-function or dual-function combinations, making it difficult to simultaneously meet the comprehensive needs of anti-glycation, firming, anti-oxidation, and penetration enhancement. Conventional compound ingredients generally suffer from poor stability, easy separation, cloudy system, sticky skin feel, and low penetration efficiency, failing to meet the formulation requirements of high-end functional cosmetics.

[0003] Therefore, this invention provides a compound skincare active ingredient with clearly defined components, scientific formulation, synergistic effects, excellent stability, and easy mass production. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a composite skincare active ingredient and its preparation method. It solves the technical problems that existing skincare ingredients are mostly single-function or dual-function compounded ingredients, which cannot simultaneously meet the comprehensive needs of anti-glycation, firming, anti-oxidation, and penetration promotion. In addition, conventional compounded ingredients generally have poor stability, easy stratification, turbidity, sticky feel, and low penetration efficiency, which cannot meet the needs of high-end functional cosmetic formulations.

[0006] Technical solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0020] Preferably, the antioxidant active component is a compound of ethyl VC and reduced glutathione;

[0021] The cosmetic-grade solvent is a mixture of propylene glycol and purified water.

[0022] Another technical problem to be solved by the present invention is to provide a method for preparing the aforementioned composite skincare active ingredient, comprising the following steps:

[0023] (1) Add cosmetic grade solvent to the reaction vessel, start stirring, speed 200-300 r / min, and control the temperature at 25℃-40℃;

[0024] (2) Add the anti-glycation active ingredient and the firming and lifting active ingredient in sequence, and stir until completely dissolved;

[0025] (3) Add the antioxidant active ingredients and continue stirring until the system is transparent and homogeneous;

[0036] The above description is merely an overview of the technical solution disclosed herein. To better understand the technical means of this disclosure and to enable its implementation according to the description, and to make the above and other objects, features, and advantages of this disclosure more apparent, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0037] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Figure 1 This is a flowchart of the preparation method of the present invention. Detailed Implementation

[0039] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0040] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0042] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0043] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0044] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0045] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.
