Description

Non-aqueous exothermic cosmetics containing activated zeolite

The present invention relates to a cosmetic that acts to warm the skin to effectively remove waste products on the skin and to promote blood circulation and metabolism.

Conventionally, heat conversion, hydration reaction, neutralization reaction, redox reaction, and frictional heat of crystalline energy using inorganic dyes have been used to promote metabolism, remove wastes easily, and enhance drug penetration by imparting warmth to cosmetics. . However, the redox and neutralization reactions were difficult to use because of their low stability to the skin because of the use of acidic groups. Therefore, since the heat generated by the hydration of the inorganic material is relatively safe and the amount of heat is large, it can be regarded as a suitable method for heat generation.

As an exothermic method by hydration of an inorganic substance, for example, Japanese Patent Laid-Open No. 51-104043 describes a means using an exothermic mechanism by reacting calcium oxide with water. In addition, Japanese Patent Laid-Open No. 57-114506, Japanese Patent Laid-Open No. 62-30704, and Japanese Patent Laid-Open No. 63-54308 disclose a method using calcined heat of calcined gypsum.

However, the present invention provides a skin-drying effect or a quick-drying gypsum pack due to the heating of alginic acid, and there is a lack of a continuous thermal effect to have a positive effect on the skin since the amount of heat is substantially insufficient.

In addition, Japanese Patent Laid-Open No. 11-49627 discloses a method of generating an inorganic salt or an organic salt by crystallization under supercooling, but basically, the amount of heat generated is insufficient and the sustainability of the heat is insufficient.

In view of the above, the invention for improving the heat storage property and the continuous heating effect is, for example, Japanese Patent Application Laid-Open Nos. 6-100411, 8-59455 and 6-80534, which are polyol insoluble polymers. And bases containing polyethylene glycol. These inventions use a hydrophilic medium and a polymer to sustain the exotherm by a competition reaction between the zeolite and the polymer when the base and water are in contact.

However, the above inventions only limit the amount of water used for hydration, and in order to control the hydration rate of the zeolite, there is a disadvantage in that a specific and direct method such as forming a physical shielding film on an external medium close to the zeolite particles cannot be used.

In addition, Japanese Patent Application Laid-open No. Hei 4-89424, European Patent No. 187,912, and US Patent No. 3,250,680 disclose exothermic cosmetics using heat of hydration of zeolite. However, the above inventions have the disadvantage that they may cause skin burns due to the instantaneous heating of the zeolite. In addition, when a large amount of zeolite is mixed in order to maintain warmth, it is difficult to manufacture a real cosmetic and there is a problem in that it is impossible to evenly disperse the zeolite evenly in a manufacturing process.

Therefore, there was a need for a cosmetic that can remove skin wastes by continually releasing safe and effective calories to the skin to promote skin metabolism and blood circulation.

The present inventors have found that by dispersing zeolite in polyhydric alcohols, the duration of exotherm can be adjusted when the cosmetic containing it is hydrated in the skin and completed the present invention. In particular, when the ethoxylate alcohol and zeolite, which are dissolved at a high temperature of about 90 ° C. or more and have a thickening effect, are mixed with polyhydric alcohol, the exothermic duration in the skin is excellent.

It is an object of the present invention to provide a non-aqueous exothermic cosmetic which is capable of maintaining an exothermic time when mixing the mixture with water by mixing an active zeolite and an ethoxylate alcohol which is a hot melting thickener with polyhydric alcohol.

In order to achieve the above object, the present invention provides a non-aqueous exothermic cosmetic containing 0.1-10 weight of ethoxylate alcohol and 10-60 weight of active zeolite.

It is preferable that the ethoxylate alcohol used for this invention has 5-25 carbon atoms, and the average degree of polymerization of ethylene oxide is 5-15. These ethoxylate alcohols are suitable for thickening polyhydric alcohols by melting at high temperatures, and when cooled to low temperatures (room temperature), they may precipitate / solidify on the surface of the zeolite, which is a solid, and in the vicinity of the surroundings, thereby slowing down the rate at which water diffuses. The content of ethoxylate alcohol is preferably 0.1-10 weight based on the total composition.

Although it does not restrict | limit especially as an activated zeolite, Zeolite 3A, 4A, 5A etc. with a large calorific value are mentioned, In addition, a special zeolite can be used. The amount of such active zeolite is preferably 10-60 weight based on the total composition.

As a solvent used for this invention, the polyhydric alcohol which is a hydrophilic non-aqueous solvent, for example, glycerin, propylene glycol, and 1,3 butylene glycol is mentioned.

The non-aqueous exothermic cosmetics of the present invention may be added to the addition of the above-mentioned essential components, a supplement, a lubricant, a scrub agent, and other auxiliary components may be added within the range that does not interfere with the effects of the present invention.

Prosthetics are added to improve usability and increase dispersion stability as the active zeolite is dispersed and the amount of the compound is increased. Examples thereof include polyacrylate, modified cellulose, hydroxypropyl methylcellulose, and the like, and the content thereof is preferably 0.1-5 weight.

As a lubricant, talc, dimethicone, or the like may be used, and when applied to the skin, 0.1 to 5 weight parts may be used to facilitate dispersibility and hand movement of the cosmetic.

Examples of the scrub agent include polyethylene powder, which is suitably in the range of 0.1-5 μm, and may be used in the range of 0.5-5 weight by use and purpose of use.

The present invention can be prepared by blending the above components in accordance with the process, and is substantially non-aqueous. In the cosmetics according to the present invention, the ethoxylated alcohol is deposited on the zeolite surface during the massage to accelerate the hydration of the active zeolite, thereby imparting a sustained effect of exotherm.

The non-aqueous exothermic cosmetics according to the present invention can be applied to creams, lotions, gels, packs, pastes and sticks.

Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited to these Examples.

(Example 1)

The ingredients shown in Table 1 were mixed to prepare a pack giving warmth.

As can be seen from the results of Table 4, when hydrating with water Comparative products 1 and 2 compared to the inventions 1, 2 and 3 showed a tendency to cool immediately after exotherm, while the invention was increased as the stirring time increases The calorific value increased and the duration of the final calorific value was longer than that of the comparative product.

Invention 3 also had a slower exotherm rate than Inventions 1 and 2, but a longer duration. This is proportional to the concentration of ethoxylate alcohol, where the ethoxylate alcohol has the effect of shielding the surface of the zeolite or adjacent media from water. Therefore, when using the present invention was found to be able to generate heat by applying physical stress to hydrate with water.

(Example 3)

Based on the inventions 1, 2, and 3 shown in Table 3, 10 women were subjected to a practical test. The results are shown in Table 5 by averaging the 5-point scale and time.

group Invention One 2 3 A (10 people) 5-point scale 4.3 4.5 - Duration of warmth in seconds 50 60 Product satisfaction level (5-point scale) 3.8 4.7 B (10 people) 5-point scale 4.5 - 4.4 Duration of warmth in seconds 45 70 Product Satisfaction (5-point scale) 4.1 3.6 C (10 people) 5-point scale - 4.6 4.3 Duration of warmth in seconds 65 90 Product Satisfaction (5-point scale) 4.6 3.7

From the results of Table 5, it was found that the duration of expression of the sense of warmth was proportional to the amount of ethoxylate alcohol by the actual massage action. However, in terms of usability, the preference of Inventive Product 2, which has a moderate thermal persistence, was found to be high, which indicates that it is a use preference that comes from high viscosity of the product.

When the non-aqueous pyrogenic cosmetic of the present invention is applied to the skin, the calorific value and the warmth persistence are excellent, promoting blood circulation, smoothing metabolism, and effectively removing the solid sebum in the skin pores, thereby making the skin clean, smooth, and elastic. It allows you to keep.
