Description

Make-up cosmetic composition and preparation method thereof

This specification discloses a makeup composition before makeup and a preparation method thereof.

Cosmetics are all products used to make an individual's body clean, beautiful, and more attractive. They refer to those that have less effect on the human body. These cosmetics also include those who are applied, sprayed or similarly applied to the body to maintain healthy skin and hair. In other words, cosmetics are products that keep the body and hair clean and healthy by properly mixing various components and applying or spraying the mixture to the body to maintain beauty. Products used for this purpose include products in various forms, such as skin toners, milky lotions, creams, essences, and foundations related to cosmetics.

Among them, make-up products are mainly composed of three components of powder-oil-water, which can be classified into base makeup and point makeup according to the composition ratio, formula or purpose of use. The base makeup such as face powder powder, compact, powder foundation, two-way cake, makeup base, liquid foundation, and cream foundation, partial Makeup such as eye shadow, powder blush, lipstick, eyeliner, and mascara.

These products are usually attached to the skin and for about 8 to 12 hours after application, and the cosmetic film attached to the skin changes with skin secretions such as sweat and sebum secreted by the skin. The change pattern of the cosmetic layer may appear in various physical forms, such as floating of the cosmetic layer, agglomerate of cosmetic particles, somber of cosmetic hue, or grease of the skin, especially for consumers. Concerns are that when these make-up products are used, the makeup of these base makeup products is unnatural due to the sebum or sweat oil secretion after makeup, which greatly reduces the makeup effect.

Therefore, the inventors of the present case conducted research in order to enhance the durability of the base makeup and show skin beauty, and found that the P / O / W type emulsion prepared by using a lipophilic surfactant will form a skin film. The rapid evaporation of water can regulate sweat and sebum and provide moisturization, so it can significantly enhance the durability of the base makeup and thus achieve the invention.

At this time, in one embodiment, the outer water phase of the present invention contains a thickener so that the inner phase and the oil phase are dispersed only in the water of the outer water phase by using the lipophilic surface activity Agent.

In this specification, the external aqueous phase may further include a thickener. The thickener increases the viscosity of water, so even if a lipophilic surfactant is present, the phase separation of the water phase portion and the oil phase portion is suppressed. Specifically, in one embodiment, the water phase portion is not mixed with the oil phase portion, but phase separation occurs when the content of the thickener relative to the total weight of the composition is 0.6% by weight or less. The content of the thickener relative to the total weight of the composition is preferably from 0.61% to 2% by weight, more preferably from 0.62% to 1%, but is not limited thereto.

In this specification, the external aqueous phase represents a part of the composition of the present invention to provide a moist feeling of use, and accounts for a large proportion in the entire composition.

In order to facilitate understanding of the present invention, the present invention will be described in detail below with reference to examples and experimental examples. The following examples and experimental examples are only used to illustrate the present invention, and are not intended to limit the scope of the present invention.

Examples 1 to 5. Preparation of cosmetics with tablet powders and spherical powders in different proportions

The cosmetics of Examples 1 to 5 were prepared by mixing these components with the compositions shown in Tables 1 and 2 below (unit: weight%). At this time, the ingredients listed in Table 1 and the ingredients listed in Table 2 are mixed in a ratio of 1: 8.

Specifically, the flake powder of Aerosil R202, Tr-2 AS, and the spherical powder of dc9701 and KSP-101 were added to a Henschel mixer and mixed together for 2 minutes. Then, the mixed powder was sprayed with Dermofeel BGC oil, Crill 6 lipophilic surfactant and perfume, and the mixture was further mixed for 2 minutes using a Henschel mixer. Subsequently, a liquid phase portion was added to the mixture, and the mixture was stirred for 10 minutes using a homogeneous mixer. At this time, the liquid phase part is a dispersed liquid phase material, which is prepared by adding all the ingredients (i.e., water, makimousse thickener and ethanol) described in the following Table 2 together and stirring for 15 minutes.

The series of processes were performed at room temperature to prepare the cosmetics of Examples 1 to 5. [Table 1] Powder, surfactant and oil phase [Table 2] Water phase part and thickener

Examples 6 to 8. Preparation of cosmetics containing hydrophilic surfactants

The compositions shown in Tables 2 and 3 above were mixed to prepare the cosmetics of Examples 6 to 8 (unit:% by weight). At this time, the ingredients listed in Table 3 and the ingredients listed in Table 2 are mixed in a ratio of 1: 8.

Specifically, Examples 6 to 8 were prepared in the same manner as the production methods of Examples 1 to 5, except that the hydrophilic surfactant Tween 60 was further added in the step of adding the lipophilic surfactant Crill 6. [Table 3] Powder, surfactant and oil phase

Example 9. Preparation of preservative-containing cosmetics

The cosmetic product of Example 9 was prepared by using the composition shown in Table 4 below (unit:% by weight). Specifically, the flake powder of Aerosil R202, Tr-2 AS, and the spherical powder of dc9701 and KSP-101 were added to a Henschel mixer and mixed together for 2 minutes. Then, the mixed powder was sprayed with Dermofeel BGC oil, Crill 6 lipophilic surfactant, perfume and Senciva sc 50 and Dermosoft GMCY preservative oil, and the mixture was further mixed using a Henschel mixer for 2 minutes. The mixture and makimousse thickener were added to an agi mixer and stirred for 15 minutes.

Thereafter, all the water and alcohol in the remaining aqueous phase portion shown in Table 4 were added thereto, and the mixture was further stirred for 5 minutes. This series of processes is performed at room temperature. As a result, the cosmetic of Example 9 was prepared. [Table 4]

Experimental Example 1. It was confirmed that the composition of the present invention has a change in use feeling according to the ratio of flake powder to spherical powder.

The cosmetic compositions of Examples 1 to 5 prepared by changing the content ratio of platelet-like powder to spherical powder were applied thinly on the front and back sides of the subject's hand in an amount of 0.5 ml. , Compare their feelings with each other.

As a result, in the case of Example 1 where the proportion of the flake powder was relatively high, dead skin cells were wiped off when the cosmetic was applied to the skin. However, it was confirmed that the situation of wiping away dead skin cells would decrease in the order of Examples 2, 3, and 4 prepared by gradually reducing the amount of flake powder. In particular, the cosmetic composition of Example 4 was applied to the skin for the first time. It is widely applied to moisturize the skin and provide the best feeling of use, and is absorbed by the skin to provide a matte feel. At the same time, in the case of Example 5 (the amount of the spherical powder is higher than that of Example 4), it has been confirmed that the powder falls off after application of cosmetics and the use feeling is slightly worse.

This shows that when the ratio of the weight of the flake powder to the total weight of the spherical powder is 0.3 to 1, the cosmetic of the present invention has the best expandability.

Experimental Example 2. Addition of a hydrophilic surfactant to confirm a change in feeling of use of the composition of the present invention

0.5 ml of the cosmetic composition of Examples 6 to 8 was applied thinly on the face and back of the individual to compare their use feelings. The preparation of the cosmetic composition further contained a hydrophilic surfactant in addition to the lipophilic surfactant.

The results confirmed that when a hydrophilic surfactant was added, the matte feeling disappeared and a thick and sticky feeling was generated, and it was confirmed that the viscosity would be maximized when the amount of the hydrophilic surfactant was increased. In other words, as a specific example, it is confirmed that the addition of a hydrophilic surfactant reduces the effect of the object of the present invention, which is to make the viscosity caused by sweat and sebum smaller (that is, a matte feeling).

Specifically, unlike the case where a hydrophilic formulation is used to make a basic moisturizing product for making a wettable formulation using a hydrophilic surfactant, in one embodiment, the emulsion of the present invention is a P / O / W type formulation, which needs to be provided The haze feels to control the secretion and moisturization of sebum or sweat, thus confirming that it is difficult to achieve the desired purpose using a hydrophilic surfactant. This indicates that the cosmetic composition of the present invention of the P / O / W type formula is a uniquely formulated cosmetic using a lipophilic surfactant, which can simultaneously provide moisturization and a matte feel.

To sum up, as a specific example, the cosmetic composition of the present invention (which is a P / O / W type emulsion containing an internal phase, a surfactant, an oil phase, and an external water phase) is used with the oil phase. Highly interactive lipophilic surfactants are produced. Therefore, when the cosmetic composition is applied, moisture is provided due to the rapid evaporation of the majority of the composition to provide a moist feeling, and because the powder capable of adsorbing the oil phase simultaneously controls sweat or sebum, a matte feeling is provided. In addition, the cosmetic of the present invention also has a waterproof effect. Therefore, as a specific example, since the cosmetic composition of the present invention can be used to improve makeup holding performance before a comprehensive base makeup, the advantages of the composition of the present invention can be used for various uses as a unique cosmetic formulation.
