Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to transparent soap. More specifically, it relates to a transparent dressing (hereinafter referred to as "margin") that improves usability, significantly improves transparency, cracking and swelling, and has good lathering by incorporating a specific cationic polymer compound.

[Prior art] Transparent soap is made by adding lower alcohol to animal fat, vegetable oil, fat-decomposed fatty acid, etc. and heating and dissolving it.
It is saponified or neutralized with an alkaline aqueous solution such as caustic soda, caustic potash, or triethanolamine, and then added with sugars such as sugar, sorbitol, and mannitol, or polyhydric alcohols such as glycerin, 1゜3-butylene glycol, and propylene glycol. Transparent soap glue is manufactured by coloring and scenting the transparent soap glue, pouring it into a prescribed cooling frame and cooling it, and after cooling and solidifying it, frame cutting, cutting, drying, shaping, etc. are performed.

Such transparent soaps are transparent and have a beautiful appearance, and are also moist and easy to clean, so they are in high demand, especially as facial cleansing soaps.

[Problems to be Solved by the Invention] However, the transparent soap produced in this manner has the disadvantage that it tends to crack or swell during the period of use, resulting in a marked deterioration in appearance. This tendency is particularly severe in systems containing large amounts of sugars and polyhydric alcohols. Since sugars and polyhydric alcohols have a great effect on moisturizing the wash, it has been desired to improve the above-mentioned drawbacks, especially in systems containing large amounts.

[Means for Solving the Problems] In view of the above circumstances, the present inventors conducted intensive research and as a result, solved the above problems by blending a specific cationic polymer compound into transparent soap. In addition to this, he discovered that the hardness of transparent soap increases, making the cooling and cutting process easier, and that it also has the effect of making the soap lather richer and creamier, and improving its transparency. The invention was completed.

That is, the present invention uses one or more poly(dimethyldiallylammonium chloride) type cationic polymer compounds represented by the following general formula (1) or (n) in
．． It is a transparent soap characterized by containing 1 to 6% by weight.

(In formulas (1) and (II), R1 and R2 represent a hydrogen atom or a methyl group, and p represents a numerical value of 150 to 6200.) (Hereinafter in the margin) The structure of the present invention will be described in detail below.

The cationic polymer compound represented by the general formula (1) or (II) used in the present invention is a poly(dimethyldiallylammonium chloride) type cationic polymer compound, and is commercially available from Merck & Co., Ltd. in the United States. Marquardt 10
0 (molecular weight 200,000 to 280,000, pure fraction 40%).

The blending amount of the cationic polymer compound is 0.1 to 6% by weight, preferably 0.1 to 6% by weight based on the total amount of the finished transparent soap composition.
．． It is 5 to 5% by weight. If it is less than 0.1% by weight, the effect will be insufficient, and if it exceeds 6% by weight, the transparency of the transparent soap will deteriorate.

The effect of the above cationic polymer compound is that transparent soap contains a large amount of sugars and polyhydric alcohols (20 to 45% by weight).
It is particularly effective when combined.

Specific examples of sugars and polyhydric alcohols include polyglycerin such as glycerin, diglycerin, triglycerin, and tetraglycerin; polypropylene glycol such as propylene glycol, dipropylene glycol, tripropylene glycol, and tetrapropylene glycol; 1.3- These include butylene glycol, butylene glycol such as 1,4-butylene glycol, sugar, sorbitol, maltitol, maltotriose, and the like.

[Effects of the Invention] The transparent soap containing the poly(dimethyldiallylammonium chloride) type cationic polymer compound of the present invention has the following effects.

(It gives a smooth feel to the skin, especially after washing.) When used in shaving soap, it has a high softening effect on the beard and reduces clogging of the shaver.

(2) It foams well and is creamy.

(3) Since it does not swell or soften, it can be used up until the end.

(4) In the manufacturing process, cooling and cutting processes become easier.

(5) The transparency of transparent soap is improved.

Although the mechanism of these actions is not clear, it is thought that the film-forming ability of the cationic polymer compound has some influence.

In addition to the above-mentioned essential ingredients, the transparent soap of the present invention may contain other ingredients as necessary, such as oil, other moisturizing agents, surfactants, and preservatives, within a range that does not contradict the purpose of the cosmetic of the present invention. agent,
Other water-soluble polymers, drugs, and other ingredients commonly added to transparent soaps can be added.

[Example] The present invention will be described in detail below with reference to Examples.

The present invention is not limited to these.

The blending amount ° is % by weight.

The effectiveness was measured using the following test method.

(1) Transparency and usability The following ratings were given based on sensory evaluation.

Very good...◎ Good......○ Fair...Δ Bad...× (2) Swelling degree The weight was measured in advance. Dip transparent soap onto a wire and immerse it in water at 20°C. After 2 hours, take it out, measure the weight, and calculate the degree of swelling using the following formula.

(However, a = weight before soaking, b - weight after soaking, C
= Weight of melted water in ice water. ) Swelling degree less than 19...◎ (very good) 19 or more 21
Less than ○ (good) 21 or more and less than 24 △ (average) Swelling degree 24 or more × (bad) (Leave blank below) (3) Using artificial hard water with foaming CaCO370P A 1% solution of transparent soap 400- was prepared, stirred for 1 minute in a cylindrical cylinder equipped with a stirrer at 25°C, and the amount of foam immediately after stirring was measured.
