Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to novel exothermic compositions with fragrance. More specifically, the present invention relates to an exothermic composition comprising a combination of a reducing agent component and an oxidizing agent component, which is useful for hair cosmetics, skin cosmetics, etc., and particularly relates to a composition having an aroma. It is.

BACKGROUND OF THE INVENTION In recent years, attempts have been made to utilize pyrogenic compositions in cosmetic products such as hair cosmetics such as hair styling agents and skin cosmetics such as shaving creams. When used in a hair styling agent, it generates heat during use, making the hair soft and easy to adjust to the desired hairstyle.When used in a shaving cream, it warms the skin and beard, making it easier to shave. It becomes easier.

Until now, cosmetics using such exothermic compositions have been developed using exothermic compositions that utilize the exothermic reaction between 1,5-diethyl-4-hydroxy-2-mercapto-6-oxopyrimidine and hydrogen peroxide. There is a known shaving cream, but this product has a strong reaction, so further improvement in safety is desired, and the fragrance used in combination deteriorates.
The disadvantage is that the usability is impaired.

Therefore, it is possible to easily generate heat when necessary to provide a desired effect without damaging the fragrance contained in the basic composition of the cosmetic. A safe and practical exothermic composition has not been known so far.

Problems to be Solved by the Invention An object of the present invention is to provide a pyrogenic composition that can be safely used in cosmetics such as hair cosmetics and skin cosmetics, and has a pleasant fragrance. be.

Means for Solving the Problems The present inventors have conducted intensive research to develop a new exothermic composition that can be used in cosmetics.

When a terpene fragrance is used in combination with a specific reducing agent and oxidizing agent, a safe and effective heat generation can be obtained, and this heat generation does not impair the fragrance's inherent aroma in any way. Based on this finding, we have accomplished the present invention.

That is, the present invention provides a reducing agent component containing (A) at least one compound selected from sodium sulfite, sodium thiosulfite, sodium pyrosulfite, and sodium bisulfite, and (B) sodium bromate and bromate. In an exothermic composition comprising a combination of an oxidizing agent component containing at least one compound selected from potassium and sodium perborate, at least one of component (A) and component CB) contains (C) a monoterpene. The present invention provides an exothermic composition having an aroma characterized by containing at least one type of fragrance ingredient selected from alcohols and monoterpene hydrocarbon compounds.

The exothermic composition of the present invention is composed of the above-mentioned (A) component, ω) component, and (0) component, of which the (4) component and (B) component are each stored in separate containers. When stored and used, the two are mixed and an exothermic reaction occurs.

Component (C) is added in advance to either or both of component (2) and (B).

The reducing agent used as component (A) in the composition of the present invention is selected from sodium sulfite, sodium thiosulfate, sodium pyrosulfite, and sodium bisulfite, and each of these may be used alone or , two or more types may be used in combination.

The amount of this component (A) is 1 to 1 based on the total weight of the composition.
It is preferable to select the amount in the range of 20% by weight, preferably 5 to 15% by weight. If this amount is less than 1% by weight, the exothermic property is insufficient, and if it exceeds 20% by weight, the stability of the fragrance (A)
This is not preferred because the solubility of the components in the system decreases.

The oxidizing agent used as component (B) in the composition of the present invention is selected from sodium bromate, potassium bromate, and sodium perborate, and each of these may be used alone, or two You may use combinations of more than one species.

The amount of this component (B) is 0.00% based on the total weight of the composition.
The amount is preferably selected within the range of 1 to 5% by weight, preferably 1 to 3% by weight. If the amount is less than 0.1% by weight, the heat generation property will be insufficient, and if it exceeds 5% by weight, the stability of the fragrance and the solubility of the component (Φ) in the system will decrease, which is not preferable. .

The heat generated by the composition of the present invention is due to the exothermic reaction between the components (A) and (B), but there is no particular restriction on the ratio of the nuclear body) component and the component CB), and the ratio is based on the stoichiometry. They may be used in a suitable proportion, or one of them may be used in excess.

The fragrance used as component (C) in the composition of the present invention is a terpene fragrance selected from monoterpene hydrocarbon compounds and monoterpene alcohols. Examples of monoterpene hydrocarbon compounds include pinene,
Limonene, myrcene, ocimene, etc., and examples of monoterpene alcohols include geraniol, nerol, linalool, borneol, etc.

These monoterpene hydrocarbon compounds and monoterpene alcohols are fragrances that are stable to both component (A) and component (B), and may be used alone or in combination of two or more. May be used.

In the composition of the present invention, the terpene flavoring component (C) is added to both or one of the components (4) and (B) in a total amount of 0.05% based on the total weight of the composition.
It is advisable to mix it in the range of ~5% by weight, preferably 0.2~3% by weight. If this amount is less than 0.05% by weight, the fragrance will be insufficient, and if it exceeds 5% by weight,
This is not preferred because it tends to deactivate component (A) and component (B). It is particularly preferable that component (C) be blended with component (A) in the above ratio.

In the composition of the present invention, both or one of the components (A) and (B) as desired.

Optional ingredients include surfactants, humectants, anti-dandruff agents, antioxidants, chelating agents, ultraviolet absorbers, viscosity modifiers, pH adjusters, disinfectants, propellants, other fragrances, colorants, etc. However, these optional components are (A
) It is desirable to add it to the ingredients.

Examples of the optional surfactant include higher alcohol sulfates, alkylbenzene sulfones [[,
Linear fulkylbenzene sulfonate, alkylnaphthalene sulfonate, alkyl phosphate, polyoxyethylene sulfate, α-olefin sulfate, N
- Anionic surfactants such as acylamino acid salts; nonionic surfactants such as polyoxy7ethylene alkyl ether, polyoxyethylene alkylphenol ether, sorbitan fatty acid ester, polyoxyethylene acyl ester; alkylamine salts, quaternary Cationic surfactants such as ammonium salts; amphoteric surfactants such as alkylamine salts can be mentioned.

These surfactants may be used alone or in combination of two or more.
