Description

Fatty acid cleanser composition with minimal water content and containing sodium silicoaluminate}

The present invention relates to a face wash composition capable of minimizing the content of water and adding sodium silicoaluminate to exhibit the characteristics of a non-aqueous face wash in a fatty acid neutralizing type cleanser face wash.

Face cleansers that show the warmth on the market are limited to non-aqueous scrubs. This is because the formulation to which the technology can be applied is very limited because the moisture content of the formulation must be very small or absent in order to feel the warmth on the skin. In particular, in the fatty acid face wash formulation that requires water to neutralize and create foam, there is no commercially available formulation for a product that generates foam and gives a feeling of heat at the same time.

Fatty acids are one of the most abundant foaming surfactants. In order to make a face wash that uses fatty acids as surfactants, soap is prepared by neutralizing fatty acids with neutralizing agents such as NaOH, KOH, and TEA. The neutralized fatty acid forms a stable formulation by adding an appropriate amount of polyhydric alcohol (glycerin, PEG, BG, etc.) and water.

In general, a lot of formulations containing an excessive amount of glycerin are used in order to give the skin a feeling of warmth. Glycerin temporarily takes away moisture from the skin, so you feel warm. Therefore, if the formulation already contains a large amount of water, glycerin cannot remove moisture from the skin, so you cannot feel the warmth.

It was attempted to identify and improve some problems of the exothermic cleansing agent using polyhydric alcohol and zeolite described in Korean Patent Application No. 10-2007-0095800.

The first is that it is a formulation that is ultimately intended for cleansing, but it does not generate abundant bubbles. Second, it is very viscous, so it is difficult to massage because it does not match the characteristics of the formulation that requires a feeling of heat through a sufficient massage process before using the face wash. Lastly, although it is a cleansing agent, it has a very high unit price as it is a non-aqueous formulation.

The goal is to develop a face wash that can ultimately be commercialized by solving these problems, and that not only gives a feeling of warmth, but also cleanses at the same time.

Accordingly, the present inventors tried to create a new exothermic cleansing composition that can provide a feeling of warmth during massage while the foam is generated abundantly.

Accordingly, an object of the present invention is to provide an exothermic cleansing composition comprising glycerin, a pyrogenic raw material, a fatty acid, an emulsion stabilizer and a neutralizing agent.

The present invention relates to a face wash composition capable of minimizing the content of water and adding sodium silicoaluminate to exhibit the characteristics of a non-aqueous face wash in a fatty acid neutralizing type cleanser face wash.

Hereinafter, the present invention will be described in more detail.

An example of the present invention relates to an exothermic cleansing composition comprising glycerin, a pyrogenic raw material, a fatty acid, an emulsion stabilizer, and a neutralizing agent.

When the content of glycerin is reduced, the calorific value is rapidly reduced, and when the content is too high, the viscosity of the formulation becomes very high, resulting in an unsuitable result due to the nature of the formulation requiring massage before face wash.

In the present invention, the exothermic raw material is 1.0 to 5.0 wt%, 1.0 to 4.5 wt%, 1.0 to 4.0 wt%, 1.0 to 3.5 wt%, 1.5 to 5.0 wt%, 1.5 to 4.5 wt%, 1.5 to 4.0 wt%, 1.5 to 3.5 wt%, 2.0 to 5.0 wt%, 2.0 to 4.5 wt%, 2.0 to 4.0 wt%, 2.0 to 3.5 wt%, 2.5 to 5.0 wt%, 2.5 to 4.5 wt%, 2.5 to 4.0 wt%, 2.5 to It may be included in 3.5% by weight, for example, it may be included in 3.0% by weight. When the content of the pyrogenic raw material is reduced, the calorific value is rapidly reduced, and when the content is too high, the viscosity of the formulation becomes very high, resulting in an unsuitable result due to the nature of the formulation requiring massage before washing.

In the present invention, the exothermic raw material provides a feeling of warmth and may be a raw material that generates heat by reacting with water or oxygen, for example, one or more selected from the group consisting of zeolite, calcium chloride, calcium oxide, sodium acetate, and gypsum. It may be, and preferably, it may be a zeolite (sodium silicoaluminate).

In the present invention, fatty acids are 10.0 to 20.0 wt%, 11.0 to 20.0 wt%, 12.0 to 20.0 wt%, 13.0 to 20.0 wt%, 14.0 to 20.0 wt%, 10.0 to 19.0 wt%, 11.0 to 19.0 wt%, 12.0 to 19.0 wt%, 13.0 to 19.0 wt%, 14.0 to 19.0 wt%, 10.0 to 18.0 wt%, 11.0 to 18.0 wt%, 12.0 to 18.0 wt%, 13.0 to 18.0 wt%, 14.0 to 18.0 wt%, 10.0 to 17.0 wt% %, 11.0 to 17.0 wt%, 12.0 to 17.0 wt%, 13.0 to 17.0 wt%, 14.0 to 17.0 wt%, 10.0 to 16.0 wt%, 11.0 to 16.0 wt%, 12.0 to 16.0 wt%, 13.0 to 16.0 wt%, For example, it may be included in 14.0 to 16.0% by weight, but is not limited thereto.

In the present invention, the fatty acid may be a C ₁₂ to C ₁₈ fatty acid, for example, stearic acid, myristic acid, palmitic acid, lauric acid ) And behenic acid may be one or more selected from the group consisting of, for example, two or more, but the present invention is not limited thereto.

In the present invention, the exothermic cleansing composition may include an emulsion stabilizer, for example, a polymer in order to increase formulation stability.

In the present invention, the emulsion stabilizer is 0.10 to 0.30 wt%, 0.12 to 0.30 wt%, 0.14 to 0.30 wt%, 0.16 to 0.30 wt%, 0.18 to 0.30 wt%, 0.10 to 0.28 wt%, 0.12 to 0.28 wt%, 0.14 To 0.28 wt%, 0.16 to 0.28 wt%, 0.18 to 0.28 wt%, 0.10 to 0.26 wt%, 0.12 to 0.26 wt%, 0.14 to 0.26 wt%, 0.16 to 0.26 wt%, 0.18 to 0.26 wt%, 0.10 to 0.24 Wt%, 0.12 to 0.24 wt%, 0.14 to 0.24 wt%, 0.16 to 0.24 wt%, 0.18 to 0.24 wt%, 0.10 to 0.22 wt%, 0.12 to 0.22 wt%, 0.14 to 0.22 wt%, 0.16 to 0.22 wt% , 0.18 to 0.22 wt% may be included, for example, 0.20 wt% may be included. If the amount of the emulsion stabilizer is small, precipitation or precipitation may occur at low and high temperatures, and if too much amount is used, the viscosity of the formulation rises rapidly, making it impossible to produce a suitable result. Stability is improved.

In the present invention, the emulsion stabilizer may be a polyhydric alcohol-based emulsion stabilizer, a carbomer, or a natural gum, for example, an acrylate/alkyl acrylate crosspolymer (Acrylates C10-30 Alkyl Acrylate Crosspolymer), an emulsion stabilizer function such as Carmober. All polymers having a can be used, and preferably, may be an acrylate C10-30/alkyl acrylate copolymer (Acrylates C10-30 Alkyl Acrylate Crosspolymer), but is not limited thereto.

In the present invention, the neutralizing agent may be one or more selected from the group consisting of KOH, NaOH, and TEA, but is not limited thereto.

In the present invention, the neutralizing agent is 2.8 to 4.0 wt%, 3.0 to 4.0 wt%, 3.2 to 4.0 wt%, 2.8 to 3.8 wt%, 3.0 to 3.8 wt%, 3.2 to 3.8 wt%, 2.8 to 3.6 wt%, 3.0 to 3.6 wt%, 3.2 to 3.6 wt% may be included, for example, 3.42 wt% may be included.

For a formulation that should generate foam at the same time as heat generation, a fatty acid neutralizing type detergent was used. Surfactants made by neutralizing fatty acids with a neutralizing agent are most preferred for detergents that generate bubbles because they generate the most abundant and elastic bubbles among surfactants.

The exothermic cleansing composition of the present invention includes water used for neutralizing fatty acids and applied a double-heating effect using zeolite and glycerin to generate a feeling of heat. When first applied to the skin, a large amount of glycerin was used to cover the water contained in the formulation while feeling the warmth, and zeolite was used to help sustain the warmth in the second skin massage step.

Since the exothermic cleansing composition of the present invention should contain the basic functions of a basic product, various raw materials such as a moisturizing component and a nutritional component may be additionally included in addition to the surfactants described above.

In addition, the exothermic cleansing composition of the present invention optionally contains components known in the technical field to which the present invention pertains, such as ethylenediamine tetraacetate (EDTA), a moisturizing agent as a conventional optional component for maintaining basic physical properties and quality. , Fatty substances, wetting substances, silicone, oil, fragrance, preservatives, clearing agents (sugar, alcohol), vitamins, proteins, pH regulators, pigments, etc. that are commonly used in the preparation of skin cleansers may be additionally included.

In addition, the exothermic cleansing composition of the present invention may include antioxidant components, skin conditioning components, skin protection components, and sunscreen components in addition to the above components.

The present invention relates to a face wash composition capable of minimizing the content of water and adding sodium silicoaluminate to exhibit the characteristics of a non-aqueous face wash in a fatty acid neutralizing type cleanser face wash, and the face wash composition of the present invention is applied to the skin before washing and massage If you do, it can give you a feeling of warmth, and when you wash your face with face wash, a rich foam is generated, so it effectively removes skin impurities and helps to make the skin smooth and healthy.

Experimental example. Sensory evaluation

Sensory evaluation was conducted on four items: feeling of warmth, amount of foam, loosening property and satisfaction. Evaluation subjects were evaluated by randomly selecting 20 women in their 20s to 30s, and the average score was given from very good (5 points) to very bad (1 point) according to preference, and is shown in Table 2 below.

In Examples 1 to 3, it was confirmed whether or not a feeling of warmth occurred by minimizing purified water and increasing the glycerin content in the fatty acid cleansing foam formulation requiring purified water. Comparative Example 1 is a comparative group for confirming the stability of the formulation, and Comparative Example 2 is a thermal cleansing composition containing polyhydric alcohol and zeolite described in Korean Patent Application No. 10-2007-0095800, designated as a comparative product of the present invention. I did. In Comparative Examples 3 and 4, it was confirmed whether heat sensation occurred when the general fatty acid neutralizing type cleanser composition and the heating material applied in the present invention were additionally applied.

Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Warmth 2.1 3.4 4.7 4.1 3.9 1.0 1.0 Foam quantity 3.7 4.1 4.8 3.8 3.5 4.7 4.5 Loosening 4.0 4.2 4.7 3.7 1.8 4.2 4.3 satisfaction 3.1 3.7 4.5 2.4 3.3 2.5 2.4

As can be seen in Table 2, in addition, in Example 3, it was determined to exhibit a higher feeling of heat than the existing non-aqueous cleansing composition, and the satisfaction was highest. In Example 2, it was confirmed that the effect of the heating agent disappeared as the content of purified water increased. In Comparative Example 1, since the emulsion stabilizer was not used, it was confirmed that the sodium silicoaluminate and the formulation were separated at low and high temperatures, so that the stability was not good. Comparative Example 2 had a high content of sodium silicoaluminate and a high sense of heat, but due to the nature of the formulation requiring massage, the loosening property was very low and thus was not suitable for use. In Comparative Example 3, it was confirmed that the effect of the heating agent disappeared as the content of purified water increased. In Comparative Example 4, it was confirmed that even if a heating material was added to a general fatty acid cleanser composition, heat was not generated when used because the moisture content was high. Accordingly, in Example 3, the foaming power and loosening properties were similar to those of the general cleanser composition, and the result was the highest satisfaction with higher heat sensation than the conventional heat cleanser composition.
