Problems solved by technology

However, the above scheme has such problems: the moisturizing ingredients are washed away without remaining on the skin during washing, therefore, the moist feeling of the skin after cleaning is poor, and it lacks low temperature stability due to containing a large amount of fatty acid salts.
However, in the above-mentioned proposal, there is such a problem that it cannot be discharged from the foaming pump due to the inclusion of a thickener, and the discharge property is poor.

Embodiment 1～33 and comparative example 1～12

[0111] Liquid skin cleansing compositions having the compositions and contents shown in Tables 1 to 8 below were produced by a usual method. Specifically, it was produced by the following method.

[0112] Heat the purified water to 70°C to 80°C, dissolve the higher fatty acid salt of (A) component or (A) comparative component and the polyol of (D) component, cool to below 40°C, and then add (B) component Cationic polymer or (B) comparative component and (C) nonionic surfactant of component or (C) comparative component to produce a liquid skin cleanser composition, the amount of the composition being the final liquid skin cleanser 95% by mass of the total amount of the composition. Afterwards, when the predetermined pH was not satisfied, potassium hydroxide was added as a common component to adjust to the predetermined pH, and then purified water was added to make the total amount 100% by mass to obtain the intended liquid skin cleanser composition. In addition, a propeller w...

Embodiment 34～43

[0237] Heat purified water to 70°C to 80°C, dissolve the higher fatty acid salt of (A) component and the polyhydric alcohol of (D) component, cool to below 40°C, then add the cationic polymer of (B) component, (C ) component nonionic surfactant and (E) the amidopropyl betaine of component, thereby manufacture liquid skin cleanser composition, the amount of this composition is 95% of the total amount of liquid skin cleanser composition finally obtained quality %. After that, when the predetermined pH was not satisfied, potassium hydroxide was added as a common component to adjust to the predetermined pH, and then purified water was added so that the total amount became 100% by mass to obtain the target liquid skin cleanser composition. In addition, a propeller was used as a stirring blade, and a three-in-one stirrer (Three one motor) (HEIDONBL1200, manufactured by Shinto Chemical Co., Ltd.) was used for stirring. In addition, pH was measured at 25° C. using a pH meter (HM-30R ...

Abstract

Provided is a liquid skin cleanser composition which can be filled in a foamer container and contains (A) 2 to 20% by mass of higher fatty acid salts including a lauric acid salt and a myristic acid salt, (B) at least one cationic polymer selected from a dimethyldiallyl ammonium chloride polymer and a (dimethyldiallyl ammonium chloride)-(acrylic acid) copolymer, (C) at least one nonionic surfactant selected from a polyoxyethylene alkyl ether having an average number of moles of added ethylene oxide units of 40 to 120 and a fatty acid monoethanolamide, and (D) a polyhydric alcohol, wherein themolar ratio of a structural unit derived from the dimethyldiallyl ammonium chloride in the (dimethyldiallyl ammonium chloride)-(acrylic acid) copolymer that is the (B)component is 65 mol% or more.

Description

technical field [0001] The present invention relates to liquid skin cleanser compositions. Background technique [0002] Conventionally, liquid skin cleansing compositions such as hand soaps and body washes have been required to be excellent in foam-related properties, touch during cleansing, and properties as products. The above foam-related properties mean, for example, the degree of a large amount of foam, the elasticity of the foam, the degree of good foamability, and the like. The above-mentioned feeling at the time of cleaning means, for example, no squeaking at the time of cleaning, a refreshing feeling at the end of washing, and the like. The properties of the product include, for example, low-temperature stability that can prevent precipitation of the components of the liquid skin cleansing composition when stored at low temperature, and the like. Further, recently, it has been strongly desired to provide a liquid skin cleanser composition having a high moisturizi...
