Description

  The present invention relates to a bubble bath composition in which creamy foam spreads on the surface of a hot water bath simply by being added to the bath water, the foam persists even during bathing, and gives a moist feeling to the skin after bathing.

  In general, a bubble bath in which bubbles are generated on the bath surface is known.

  Conventionally, such bubble baths have been bubbled using a shower or faucet water pressure when a hot water is put in the bathtub.

  Therefore, a large amount of surfactant has been blended in the bubble bath agent because foaming and foam persistence are required.

  However, when foaming by using the water pressure of a shower or a faucet like the above-mentioned conventional bubble bath agent, if you inadvertently forget to add the bubble bath agent, you must put the bubble bath agent later and stir and boil it. This will cause inconveniences such as troublesomeness.

  Further, in the case where a large amount of a surfactant is blended like the above-mentioned conventional bubble bath agent, the effect of the surfactant is lacking in moisturizing property after bathing, resulting in a problem that the skin becomes bulky.

  The present invention has been made in view of the actual situation, and by simply putting it in the bath water stretched on the bathtub, creamy foam spreads on the surface of the bath, the foam persists during bathing, and after bathing It aims at providing the bubble bath composition which gives a moist feeling to the skin.

  As a result of intensive studies on the above problems, the present inventors have found that the sucrose fatty acid ester is creamy foam generated when dissolved in the bath water and the bubbles and dissolved oxygen present in the bath water. The foam generated by arranging at the gas-liquid interface rises and foams as creamy foam on the bath surface, and at the same time the polyalkylene oxide or its cross-linked polymer is dissolved in the bath water to strengthen the foam film, It has been found that a bubble bath composition that improves the persistence of foam and gives a moist feeling to the skin after bathing has been completed, and the present invention has been completed.

  That is, the present invention is a bubble bath composition characterized by having a sucrose fatty acid ester and a polyalkylene oxide or a crosslinked polymer thereof. Specifically, the sucrose fatty acid ester and a polyalkylene oxide or a crosslinked polymer thereof are specifically described. It is a bubble bath composition characterized by containing a thing.

  The bubble bath composition of the present invention is composed of the following components.

  The sucrose fatty acid ester used in the present invention is obtained by esterifying eight hydroxyl groups in one sucrose molecule with a fatty acid, and is a monoester obtained by reacting one molecule of fatty acid with one molecule of sucrose. To octaesters reacted with 8 fatty acid molecules, but in actual industrial production, they are obtained as a mixture of these esters. This sucrose fatty acid ester is safe with little skin irritation since sucrose, which is a natural component, is used as a starting material.

  The fatty acid in the above sucrose fatty acid ester is a saturated or unsaturated, linear or branched fatty acid having 8 to 22 carbon atoms, specifically, for example, caprylic acid, capric acid, octanoic acid, Saturated fatty acids such as decanoic acid, lauric acid, myristic acid, palmitic acid, stearic acid, isostearic acid, behenic acid, erucic acid, unsaturated fatty acids such as oleic acid, linolenic acid, linoleic acid, coconut oil fatty acid, palm kernel oil fatty acid And mixed acids. The sucrose fatty acid ester can be used without any particular limitation as long as it maintains good foaming and foam persistence. Preferably, sucrose stearic acid is used to generate creamy foam. Ester.

  These sucrose fatty acid esters can be used alone or in combination of two or more. The blending amount is preferably 1 to 20% by mass, more preferably 1 to 10% by mass in the bubble bath composition of the present invention.

◎: 5.0 or more ○: 4.0 or more and less than 5.0 △: 3.0 or more and less than 4.0 ▲: 2.0 or more and less than 3.0 ×: Less than 2.0

表１より、実施例１〜８は、いずれもショ糖脂肪酸エステル及びポリアルキレンオキサイドが配合されており、浴湯に投入するだけでクリーミーな泡を発生させ、かつ、その泡が入浴中にも消泡しないことがわかる。また、実施例２〜４に示すように、その他の成分を配合しても泡のクリーミーさや持続性に何ら問題はないことがわかる。

From Table 1, Examples 1-8 are all compounded with sucrose fatty acid ester and polyalkylene oxide, generate creamy foam just by adding to bath water, and the foam is also in bathing. It turns out that it does not defoam. Moreover, as shown in Examples 2-4, it turns out that there is no problem in the creaminess and sustainability of a foam even if it mix | blends another component.

  Here, as shown in Comparative Examples 1 to 3, for those blended with an anionic surfactant or an amphoteric surfactant, there is no occurrence of fine creamy foam and no persistence of foam. . However, although the comparative example 4 mix | blended sucrose fatty acid ester and was able to obtain creamy foam at the time of bath water addition, it turns out that the foam does not continue and it defoams. Furthermore, in Comparative Example 5, the amount of sucrose fatty acid ester was reduced, but there was no problem with foam creamy. In Comparative Example 6, since the blending amount of the sucrose fatty acid ester was less than 1%, no creamy foam was observed. In Comparative Example 7, foaming at the time of adding hot water was good due to the blending of sucrose fatty acid ester, but since the blending amount of polyalkylene oxide was less than 1%, the foam did not persist.

  As is clear from the above, according to the present invention, a creamy foam can be formed by combining a sucrose fatty acid ester with a polyalkylene oxide such as polyethylene oxide or polypropylene oxide or a cross-linked polymer thereof, just by adding it to the bath water. A bubble bath composition is obtained which spreads on the surface of the hot water, maintains the bubbles even during bathing, and gives a moist feeling to the skin after bathing.

  It can be used as a bathing agent for bubble baths.
