Description

Heating compositions for personal cleansing containing powdered surfactant and natural powder

The present invention relates to a composition for cleansing the human body that generates a feeling of warmth when applied to the skin, and more particularly, to a composition for human body cleansing that does not contain a polymer and contains a powder-type surfactant and natural powder, which has excellent coating and warmth.

In general, thermal pack products include a product that has a heating effect by the heat of hydration of polyhydric alcohols and a product that has a heating effect by a synthetic zeolite, which is a kind of aluminosilicate mineral.

When a thermal pack product is applied to the skin, in order to maintain a warm feeling, it must be a high-viscosity liquid and have excellent skin adhesion. For this purpose, a polymer stabilizer is generally used to form a high viscosity in the thermal pack composition. Japanese Patent Application Laid-Open No. Hei 5-320038, Japanese Unexamined Patent Application Publication No. Hei 6-92820, and Japanese Unexamined Patent Application Publication No. Hei 5-229926 as related patent inventions contain 10% or less moisture content, 70-90% polyhydric alcohol, and an anionic water-soluble polymer. A viscous formulation is disclosed. However, when anionic water-soluble polymers are used, there is a disadvantage in that the coating feeling is deteriorated when the pack is applied, and it is difficult to realize a fresh feeling of use due to the residual feeling of the polymer stabilizer.

Korean Patent Laid-Open No. 2004-0056159 discloses a non-water-emulsifying pyrogenic cosmetic composition containing zeolite as a pyrogenic raw material. However, since zeolite generates heat within a short time when it reacts with water, it is difficult to expect a continuous and high thermal effect.

Therefore, there is a need to develop a thermal wash-off pack product in which the problems of the polymer stabilizer or mineral raw material are solved.

The problem to be solved by the present invention is to provide a composition for human body cleansing that does not contain a polymer stabilizer and forms high viscosity, so that it has excellent warmth and heat lasting power, excellent skin feel, and less residual feeling.

In addition, another problem to be solved by the present invention is to provide a wash-off cleaning pack comprising the composition for cleaning the human body.

As a result of intensive research efforts to overcome the problems of the prior art, the present inventors have excellent formulation stability and improved skin adhesion with a high-viscosity formulation when a powder-type surfactant and natural powder are included in a cleaning pack composition containing a polyhydric alcohol. And it was found that the heat durability is excellent. In addition, the composition can reduce the residual feeling of the pack by forming fine bubbles when washing the face, and also has an excellent skin cleansing effect.

In addition, since the composition does not need to use a stabilizing polymer (eg, carbopol) stabilizer that is commonly used for formulation stability, it has a superior coating feeling compared to a cleaning pack composition containing a polymer stabilizer and gives a refreshing feeling after use. , and the present invention was completed.

The present invention provides a composition for thermal body cleansing comprising 60 to 90% by weight of a polyhydric alcohol, 1 to 20% by weight of a powder-type surfactant, and 1 to 20% by weight of a natural powder based on the total weight of the composition.

In the present invention, the composition can maximize the thermal effect and at the same time stabilize the formulation by maximizing the content of polyhydric alcohol in the composition. The polyhydric alcohol is glycerin, diglycerin, polyglycerin, dipropylene glycol, polyethylene glycol, 1,3-butylene glycol, trimethylolethane, trimethylolpropane, erythritol, pentaerythritol, sorbitol, glucose, sorbitol It may include any one or more selected from the group consisting of tan, maltitol, sucrose, raffinose, and trehalose. Preferably, as the polyhydric alcohol, glycerin, diglycerin, or a mixture thereof with high viscosity may be used, and in this case, formulation stability and heat retention were excellent.

The polyhydric alcohol may be included in an amount of 60 to 90% by weight, preferably 65 to 85% by weight, and more preferably 70 to 80% by weight relative to the total weight of the composition. When the polyhydric alcohol is less than 60% by weight, the feeling of warmth is reduced, and when it is more than 90% by weight, the foaming effect is inhibited.

In the present invention, since the powder-type surfactant can increase the viscosity of the formulation when dissolved in polyhydric alcohol, the composition of the present invention does not require a separate water-soluble stabilizing polymer. The powder-type surfactant may be a solid powder type irrespective of ionicity such as cationic or anionic, and a liquid surfactant does not improve the viscosity of the composition, so it is not suitable for use in the composition of the present invention.

The powder-type surfactants include alkyl sulfates including ammonium lauryl sulfate, sodium lauryl sulfate, TEA lauryl sulfate, and MIP lauryl sulfate; amino acid series including sodium methyl cocoyl taurate, sodium lauroyl sarcosinate, sodium lauroyl glutamate, and sodium cocoyl glutamate; Isethionates including sodium cocoyl isethionate, sodium lauroyl isethionate, sodium myristoyl isethionate, sodium oleyl isethionate, and ammonium cocoyl isethionate. ; amphoacetates including disodium cocoamphoacetate, sodium lauroamphoacetate and sodium lauroamphodiacetate; betaines including cocamidopropyl betaine, lauramidopropyl betaine, and oleamidopropyl betaine; and sodium lauryl sulfoacetate, sodium cocosulfoacetate, and sulfoacetates including disodium hydroxysulfoacetate, etc. may include any one or more selected from the group consisting of. Preferably, when isethionates are used as the powder-type surfactant, they are dissolved in glycerin, a polyhydric alcohol, at 90° C. or higher, and the viscosity is excellent, and more preferably, sodium cocoyl isethionate may be included.

The powder-type surfactant may be included in an amount of 1 to 20% by weight, preferably 3 to 18% by weight, more preferably 5 to 15% by weight, based on the total weight of the composition. When the amount of the powder-type surfactant is less than 1% by weight, it is difficult to form a high-viscosity formulation, stability is lowered, and the foaming power is lowered, and when it is more than 20% by weight, the viscosity is too high to lower the coating feeling and there is a pulling phenomenon after washing.

In the present invention, the natural powder helps to form a high-viscosity formulation together with a powder-type surfactant, prevents phase separation at high temperatures even without containing a polymer stabilizer, and is used as a means for improving cleaning power by fine particles.

The natural powder may be any of those commonly used to increase the viscosity in the art, and minerals including mica, bentonite, kaolin, hectorite, and montmorillonite; And it may include any one or more selected from the group consisting of plant skin powder, fruit peel powder, fruit powder, and plant powder including grain powder, and the like. In addition, the plant powder includes rice bran powder, soybean powder, mung bean powder, red bean powder, potato powder, or wheat flour. Preferably, as the natural powder in the present invention, rice bran powder having excellent cosmetic effects may be used.

The natural powder may be included in an amount of 1 to 20% by weight, preferably 3 to 18% by weight, and more preferably 5 to 15% by weight relative to the total weight of the composition. When the amount of the natural powder is less than 1% by weight, high temperature stability may be reduced, and if it is more than 20% by weight, the viscosity is too high, so that the coating feeling is deteriorated and there is a risk of skin irritation.

In the present invention, the composition may contain water in a minimum amount that does not inhibit the feeling of warmth, and may contain 5% by weight or less, preferably 2 to 4% by weight, based on the total weight of the composition. When the amount of water exceeds 5% by weight, the stability of the high-viscosity formulation is lowered and the durability of the warm feeling is lowered.

In the present invention, the composition does not substantially contain a polymer (especially a carbopol type polymer) stabilizer, so it has an excellent skin feel compared to a composition containing a polymer stabilizer and gives a refreshing feeling after use. By means that the composition is substantially free of polymeric stabilizers, it may comprise less than 5% by weight, preferably less than 3% by weight, more preferably less than 1% by weight of the polymeric stabilizer relative to the total weight of the composition, most preferably It means that it does not contain any polymer stabilizers.

The composition according to the present invention may be used for cleaning the scalp, face, body, or hands and feet for human body cleaning, and the area of use is not particularly limited. Preferably, the composition can be used for face washing, is contained in a high-viscosity wash-off type face-wash pack, is applied to the skin and massaged to give a warming effect, and can exhibit an excellent cleansing effect by rinsing it off.

The composition according to the present invention may be used in formulations such as gels, lotions, creams, essences, ointments, foams, packs, emulsions, or liquid detergents. Preferably, the composition may be prepared and used in the form of a high-viscosity gel, and in this case, it has excellent adhesion when applied to the skin, so that the feeling of heat and heat lasting power are excellent.

The composition according to the present invention may further include any one or more selected from the group consisting of fragrances, pigments, preservatives, humectants, chelating agents, bactericides, antioxidants, and fragrances commonly used in the art.

The present invention provides a composition for warm body cleansing comprising 60 to 90% by weight of glycerin, 1 to 20% by weight of sodium cocoyl isethionate, 1 to 20% by weight of rice bran powder, and 1 to 5% by weight of water relative to the total weight of the composition provides The composition for thermal cleansing of the human body having the above composition ratio is most preferred because it is in the form of a high-viscosity gel with excellent formulation stability, has excellent cleaning power and skin feeling, and gives a refreshing feeling after use.

In addition, the present invention provides a high-viscosity gel wash-off cleaning pack comprising the composition for cleaning the body and generating a warm feeling when applied to the skin. The wash-off cleaning pack is in the form of a high-viscosity gel, and has excellent skin adhesion, and thus has excellent heat lasting power when applied to the skin.

The embodiments of the present invention are provided to more completely explain the present invention to those of ordinary skill in the art.

Preparation of face pack compositions of Examples and Comparative Examples

According to the composition ratio shown in Table 1 below, the polyhydric alcohol was heated to dissolve the powder-type surfactant at 90° C. or higher, and then at 70° C. or less, a stabilizing polymer, natural powder, water, and a preservative were mixed to form Examples 1 to 5 and Comparative Examples Face pack compositions of 1 to 5 were prepared.

Experimental Example 1: Formulation stability evaluation

For formulation stability evaluation, the contents prepared by the above method were placed in a container and stored for 4 weeks at each temperature, and then the stability was visually evaluated. The evaluation criteria are shown in Table 2 below, and the evaluation results are shown in Table 3 below.

Item Very poor stability (phase separation) Slightly weak stability good stability Very good stability score 0 One 2 3

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Formulation stability 50℃ 3 2 2 2 3 0 0 One One 0 0℃ 3 3 3 3 2 One 2 2 2 One FT(-20~-40℃) 3 3 2 2 2 One One One One One

As shown in the above results, when the powder-type surfactant and the natural powder were not included at the same time (Comparative Examples 1 and 2), stability was not maintained. In addition, when the powder-type surfactant and the natural powder are not included at the same time, it can be seen that the stability is not excellent even when a generally well-known stabilizing polymer is used (Comparative Examples 3 and 4). In addition, stability was not maintained even when a liquid surfactant was used (Comparative Example 5).

Experimental Example 2: Evaluation of usability

For the usability evaluation, 20 women in their 20s and 40s were selected, and after using each product twice, scores were indicated according to the evaluation criteria. The results are as follows.

How to use: After washing your face with a general cleanser, remove the moisture, apply an appropriate amount of the wash-off cleaning pack to your face, massage, leave it for about 5 minutes, and then rinse it off with lukewarm water.

1) Coating feeling

When the high-viscosity formulation is applied to a dry face, the degree of spread easily and the feeling of use when applied were evaluated. The evaluation criteria of the coating feeling are shown in Table 4 below, and the evaluation results are shown in Table 5 below.

Item Very poor coverage Slightly weak in application Good coverage Very good spreadability score 0 One 2 3

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 feeling of coating 2.8 2.9 2.4 2.3 2.8 2.1 1.5 One 0.9 1.8

When the powder-type surfactant and natural powder are not contained at the same time (Comparative Examples 1 and 2), the viscosity is low and the coating feeling is poor, and when a stabilizing polymer is used to increase the viscosity (Comparative Examples 3 and 4) It can be seen that the sensitivity decreases. In addition, it was confirmed that even when a liquid surfactant was used (Comparative Example 5), the viscosity was low and the coating feeling was inferior.

2) sense of warmth

After washing the face, remove the moisture and evaluate the warmth felt around the face and nose when using the wash-off face pack. As for the duration of warmth, it was evaluated that the feeling of warmth was maintained during 5 minutes of standing after massage. The evaluation criteria for the feeling of warmth are shown in Table 6 below, and the evaluation results are shown in Table 7 below.

Item very bad somewhat vulnerable good very good score 0 One 2 3

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 warmth initial warmth 2.8 2.6 2.6 2.7 2.6 2.7 2.7 2.6 2.5 2.6 longevity of warmth 2.8 2.7 2.5 2.3 2.3 1.2 1.5 1.3 1.7 1.4

As in the above results, when the polyhydric alcohol was contained in an amount of 60% or more, the initial warm feeling was excellent. However, when the powder-type surfactant and the natural powder were not contained together (Comparative Examples 1-4) and when the liquid surfactant was contained (Comparative Example 5), the skin adhesion was lowered, and the heat retention while using the pack was reduced. .

3) Residual feeling after washing with water

After using the wash-off face pack, the residual feeling of the pack remaining on the skin was evaluated while rinsing with lukewarm water. The evaluation criteria for residual feeling are shown in Table 8 below, and the evaluation results are shown in Table 9 below.

Item There is a residual feeling Slightly bad with residual feeling No residue Good No residue Excellent score 0 One 2 3

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Residual feeling after washing with water 2.7 2.9 2.4 2.3 2.5 1.8 2.3 0.9 1.5 2.0

When looking at the results shown in Table 9, when the stabilizing polymer is used (Comparative Examples 3 and 4), there is a lot of residual feeling after washing with water, so it is not suitable as a wash-off face pack. It can be seen that due to the cleaning effect of natural powder, there is little residual feeling after washing, giving a refreshing feeling of use.
