DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic which is capable of solubilizing a water-insoluble oil having a low flash point, such as a fragrance, in water to raise the flash point and which can be used as it is in the production of cosmetics and detergents. Or, it relates to a liquid material for detergent production.

[0002]

2. Description of the Related Art Conventionally, cosmetics such as shampoo, rinse and body soap,
2. Description of the Related Art A non-water-soluble oil such as a fragrance is blended into a household detergent such as dishwashing. However, when such water-insoluble oils are blended into cosmetics or detergents such as liquids, they need to be solubilized in water at the time of blending, but this solubilization requires large mechanical power and the like. There is also a problem in terms of gender. Further, many of the above-mentioned fragrances have a flash point of 21 ° C. or higher and lower than 70 ° C. and have a low flash point, so that careful handling is required not only during storage but also during compounding. Greater care is needed, especially when the flash point is close to the operating temperature in the manufacturing process.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is intended to make cosmetics or cosmetics having remarkably enhanced handleability and compoundability by solubilizing water-insoluble oils having a low flash point, such as fragrances, in water. It is an object to provide a liquid material for detergent production.

Means for Solving the Problems and Embodiments of the Invention The present inventors have made intensive studies to achieve the above object, and as a result, have reached the present invention. That is, the present invention provides (1) a water-insoluble cosmetic or detergent raw material having a flash point of 21 ° C. or higher and lower than 70 ° C., water, and a surfactant for solubilizing the cosmetic or detergent raw material in water. And the agent in a weight ratio of 1: 0.4 to 1.5:
By mixing at a ratio of 0.1 to 1.0, the raw material for cosmetics or detergent is solubilized in water, and the flash point is 70 ° C.
And (2) a water-insoluble cosmetic or detergent raw material having a flash point of 21 ° C. or more and less than 70 ° C .; water; A surfactant for solubilizing a detergent or a raw material for detergent in water and a polyhydric alcohol are used in a weight ratio of 1: 0.4 to 1.5: 0.1 to
The cosmetic or detergent raw material is solubilized in water by mixing at a ratio of 0.5: 0.05 to 0.5, and the flash point is 70 ° C. or higher. Provide a liquid material for detergent production.

[0005] The liquid material for producing cosmetics and detergents of the present invention has a low flash point of a water-insoluble liquid raw material which is solubilized in water and has a high flash point of 70 ° C or higher. High safety during compounding such as mixing with raw materials,
The handling considerations are reduced, and the vapor pressure at the same temperature is reduced as compared to the case where the above-mentioned liquid raw material is used as it is. In this case, quality deterioration such as a change in scent quality due to volatilization of low-boiling components is suppressed, and high-quality cosmetics and detergents can be manufactured. In addition, the liquid material for producing cosmetics and detergents according to the present invention may have a low temperature (−5 ° C.) to a high temperature (50 ° C.).
Stable over a wide temperature range up to and low viscosity (0.05P
a.s or less) can be used as the solubilized liquid, so that there are almost no restrictions on storage and handling, and it is excellent in storage and handling.

Further, a large mechanical force is required for directly adding a water-insoluble liquid to a water-soluble product and uniformly dispersing the same, but by using the liquid material for producing cosmetics and detergents of the present invention, It is easily dispersed by a general-purpose stirring device, and has excellent dispersibility.

Hereinafter, the present invention will be described in more detail. As described above, the liquid material for producing a cosmetic or detergent according to the present invention comprises (1) a water-insoluble cosmetic material having a flash point of 21 ° C. or more and less than 70 ° C. Ingredients for detergents or detergents, (2) water, (3) surfactants for solubilizing the ingredients for cosmetics or detergents in water,
Further, if necessary, (4) a polyhydric alcohol is mixed at a specific weight ratio.

The water-insoluble cosmetic or detergent raw material of the component (1) has a flash point of 21 ° C. or higher at 1 atm.
It may be any water-insoluble cosmetic or detergent raw material which is less than 0 ° C and is blended in cosmetics, shampoos, rinses, body soaps, household detergents, etc. Specifically, alcohols such as fragrances and hexanol And esters such as butyl propionate, and acids such as propionic anhydride. The fragrance may be a single fragrance or a compounded fragrance. Further, the raw material is not limited to one kind, and two or more kinds may be solubilized.

The surfactant of the component (3) solubilizes the above-mentioned raw materials for cosmetics or detergents in water, and may be any of anionic, nonionic, cationic and amphoteric surfactants. And these may be used in combination, but are preferably water-soluble. In particular,
Soaps, alkylbenzene sulfonates, alkyl sulfates, etc. as anionic activators, polyoxyethylene alkyls, polyoxyethylene sorbitan fatty acid esters, polyethylene glycol fatty acid esters, amine oxides, etc. as nonionic activators, and aliphatic quaternary amines as cationic activators Examples of amphoteric activators such as salts include carboxybetaine, aminocarboxylate, imidazolinium betaine and the like. HLB is used as a surfactant.
Is preferably 7 to 35, particularly preferably 9 to 20.

The polyhydric alcohol of the component (4) includes propylene glycol, 1,3-butylene glycol and the like.

In the liquid material for producing a cosmetic or detergent according to the present invention, when the above components (1) to (3) are used, the water of the component (2) is added in an amount of 0.1 part by weight to 1 part by weight of the material of the component (1). 4-1.
5 parts by weight, preferably 0.8 to 1.5 parts by weight, and 0.1 to 1.0 part by weight, preferably 0.15 to 1.0 part by weight of the surfactant (3). To make the component (1) soluble in water. in this case,
When the amount of the component (2) water is less than 0.4 parts by weight, the effect of increasing the flash point is small, and when the amount is more than 1.5 parts by weight, the effect does not change, but the content of the component (1) decreases. There is a disadvantage. If the amount of the component (3) is less than 0.1 part by weight, the effect of solubilizing the component (1) in water is not obtained. Even if the amount exceeds 1.0 part by weight, the effect is not changed.

When the liquid material of the present invention is produced using the above components (1) to (4), 0.4 to 1.5 parts by weight of the component (2) is used per 1 part by weight of the component (1). , Preferably 0.8 to 1.5 parts by weight, component (3) 0.1 to 0.5 part by weight, preferably 0.15 to 0.5 part by weight, and component (4) 0.05 to 0 part by weight. 0.5 parts by weight, preferably 0.1 to 0.5
It is preferred to use parts by weight. (4) If the amount of the component is too small, the solubilizing effect may be poor.

It is to be noted that other components may be added to the liquid material as long as the effects of the present invention are not impaired.

There is no particular limitation on the mixing method when the liquid material of the present invention is prepared from the above-mentioned components, and the above-mentioned component (1) can be easily and easily prepared by a usual mixing method using a stirring tank equipped with paddle blades. It can be surely solubilized in water.
