Description

Description: TECHNICAL FIELD The present invention relates to a bath preparation composition, and relates to a novel bath preparation composition containing monkey fat and / or a hydrogenated product thereof and having excellent cosmetic effects. .

[Conventional technology]

Conventionally, various types of bath compositions have been known to be used by adding them to bath water. In the case of powder or granules, sodium sulfate, sodium hydrogen carbonate, borax, sodium sesquicarbonate, etc. In order to protect the skin or improve the feel to the skin, for example, lanolin, lanolin derivatives, isopropyl myristate,
The main ingredients are softeners such as isopropyl alcohol, squalane, pyrrolidone carboxylate, glycerin, propylene glycol, other animal and vegetable oils and their esters, and most of them contain pigments, fragrances, fungicides, etc. is occupying.

Of these base agents, softeners are indispensable to bath agents because they soften the skin of the bather after bathing and give a moist feeling.

However, these raw materials which have been conventionally used as softeners have a problem in their compounding amount, and stickiness to the skin cannot be avoided by increasing the compounding amount, and the use amount is limited. Further, the above softeners are not preferable in terms of compatibility with other raw materials and dispersibility when a bath agent is put into hot water in a bathtub, and also have poor stability over a long period of time and quality deterioration. Met.

[Problems to be solved by the invention]

Therefore, the present inventor has studied to find a new softener for the bath composition, and as a result, the use of monkey fat and / or a hydrogenated product thereof as a softener for the bath composition has resulted in a less oily smooth surface. It can give a feeling to the skin after bathing, and can be blended in a large amount in the same manner as jojoba oil, which has been widely used as a softener, in terms of the blending amount, which is a conventional drawback, and has a good dispersibility in hot water. It has been found that a very good bath composition is obtained.

[Means for solving the problem]

The present invention is a bath agent composition containing monkey fat and / or a hydrogenated product thereof.

 Hereinafter, the present invention will be described in detail.

The monkey fat is mainly an oil or fat extracted from a 30 to 50-m-long evergreen coconut tree (Sal Seed) called Sal Tree, which grows on the other side of India in a cluster or other kinds of forests. The core of Sara Soju's fruit is 4-20% moisture and 13 oil
At ~ 20%, it is extracted with hexane. The obtained monkey fat crude oil is a dark green oil, which is deacidified, decolorized and deodorized by a usual method to obtain white or pale yellow waxy purified monkey fat.

Monkey fat has a triglyceride structure like other vegetable oils, and about 40% of the unsaturated fatty acids contained are mostly oleic acid, so it has excellent oxidative stability, and the saturated fatty acids are stearic acid, palmitic acid, and arachiic acid. Is included.

Monkey fat is waxy at room temperature, but has a melting point of 30-35
At 0 ° C., the oil has good dispersibility and excellent feel in bath water.

 The properties of the purified monkey fat are as follows.

Saponification value Approx. 190 Iodine value Approx. 40 Acid value 0.1 Melting point 31 ° C Monkey fat becomes a white solid when hydrogenated according to a conventional method.

 The properties of the hydrogenated monkey fat are as follows.

Saponification value: about 190 Iodine value: about 20 Acid value: 0.1 Melting point: 48 ° C. The monkey fat in the present invention may be either crude crude fat or purified purified monkey fat.

Further, in addition to the above-mentioned components, the bath agent composition of the present invention may further contain, if necessary, a bactericidal preservative (eg, benzoic acid, benzoic acid ester, sorbic acid, etc.), a metal sequestering agent (eg, EDT
A, NTA, citric acid, etc.) and a wide range of other raw materials.

Next, a method for producing the bath agent composition of the present invention will be described.

The bath composition of the present invention may be any method as long as it is a method in which monkey fat or a hydrogenated product thereof previously heated and dissolved in the above-mentioned other components is added and uniformly mixed.

The amount of the additive was 0.1
The # 80 to # 80 positions are preferred, especially 0.1 to 5 for powders, 5 to 80 for bath oils and 1 to 5 for bubble baths. By the way, the amount of olive oil to be added is only about one-third of the amount of monkey fat or its hydrogenated product, and if it is added more than that, stickiness to the skin and the like cannot be obtained, and a favorable result cannot be obtained.

The dosage form of the bath composition can be any form such as powder, liquid, and solid.

〔The invention's effect〕

In the present invention, a bath composition having extremely good dispersibility can be obtained by adding monkey fat and / or a hydrogenated product thereof to a bath material. In other words, in the case of a conventional bath agent, the oil often becomes spherical and floats due to poor dispersibility when poured into hot water, which gives the bather discomfort and also causes the oil to adhere to the bathtub. Although not preferred, the bath composition of the present invention has excellent dispersibility, does not become spherical, can give a soft feeling to the entire skin of the bather, and is also a very excellent feature that does not easily adhere to the bathtub. It has. In addition, the bath composition of the present invention is stable without being deteriorated for a long time even when mixed with various inorganic salts in the case of powders and granules, and has good dispersibility even in the case of a liquid, so that it can be used with various raw materials. Has a great advantage in terms of solubilization, and also has a good long-term emulsion stability.

For example, even when the conventional bath agent composition is uniformly dissolved at the time of production, the oil agent component is liable to be oxidized, turbid and separated when stored for a long period of time. The bath composition of the present invention is stable for a long period of time, does not show any deterioration in quality, and shows extremely excellent dispersibility even when put into hot water.

As described above, the bath agent composition of the present invention is stable even when stored for a long period of time, has extremely excellent dispersibility in hot water, and gives the skin a comfortable feel that is dry and comfortable after bathing. It has excellent performance as a bath agent.

Next, an experimental example in which the efficacy of the bath preparation composition of the present invention is compared with that of the conventional bath preparation composition shows that the bath preparation composition of the present invention is excellent in dispersibility, skin smoothness and stability. This will be specifically described.
