Description

Liquid skin cleanser product {LIQUID SKIN CLEANSER PRODUCT}

The present invention relates to a liquid skin cleanser product in which slippage during rinsing is reduced and the rinsing time is shortened.

Conventionally, skin detergents have a good fresh feeling after washing, and higher fatty acid salts are used as a washing base material. However, while the fatty acid salt was refreshing after washing, there was a slippery at the time of rinsing, and it was a difficult point that it took time to rinse.

To reduce the slippage during rinsing, detergents containing anionic surfactants have been proposed, but since it is difficult to detect slippage with only anionic surfactants, a sugar alcohol derivative and hydrolyzed plant protein are combined. Thus, attempts have been made to enhance the refreshing feeling after rinsing even when a slipperiness is felt during rinsing. However, the balance between the refreshing feeling after rinsing and the shortening of the rinsing time was not sufficient (Patent Document 1: Japanese Unexamined Patent Publication No. 2010-180182).

On the other hand, attempts have been made to improve the foaming quality by blending a cationic polymer, but compatibility with shortening the rinsing time was not sufficient (Patent Documents 2 and 3: Japanese Patent Laid-Open Publication No. 2004-204087, Japanese Unexamined Patent Publication). 2005-15359 publication). Detergents having increased foaming quality by blending polyols have also been proposed, but the effect of shortening the rinsing time was not sufficient (Patent Document 4: Japanese Unexamined Patent Publication No. 2002-080345).

Anyway, it is the current state that no skin detergent that can be rinsed in a short time has been obtained, and the rinsing time is fast, and it is excellent in foam elasticity and foam quality, and a fresh feeling can be obtained after rinsing, and the foamer container Skin detergents that can be used are unknown.

Japanese Unexamined Patent Publication No. 2010-180182 Japanese Patent Laid-Open Publication No. 2004-204087 Japanese Patent Laid-Open Publication No. 2005-15359 Japanese Unexamined Patent Publication No. 2002-080345

[(A) Fatty acid salt]

(A) component used in the present invention is the following formula (1)

R ¹ COOM (1)

(In the formula, R ¹ represents a linear or branched monovalent hydrocarbon group having 7 to 21 carbon atoms, and some of the hydrogen atoms of the hydrocarbon group may be substituted with a hydroxyl group. M is an alkali metal or an alkanolamine. )

It is a fatty acid salt represented by and is blended to obtain good detergency, foamability and foaming. (A) A component can be used individually by 1 type or in combination of 2 or more types suitably. In the above general formula (1), R ¹ represents a monovalent hydrocarbon group such as a linear or branched alkyl group or alkenyl group having 7 to 21 carbon atoms, and some of the hydrogen atoms of the hydrocarbon group may be substituted with a hydroxyl group. . M represents an alkali metal or an alkanolamine, specifically, the alkali metal is preferably potassium and sodium, and the alkanolamine is preferably monoethanolamine, diethanolamine, triethanolamine, diisopropanolamine, or the like. From the viewpoint of lathering, rinsing time, and fresh feeling after rinsing, R ¹ is a straight chain having 11 to 15 carbon atoms, and M is more preferably potassium.

Further, when R ¹ is a a carbon number of 7, a fatty acid salt component monovalent hydrocarbon group of 1 to 11 A ^1, R ¹ is a carbon number of 12 to 21 1 to the hydrocarbon fatty acid salts component to A ^2, combined use of A ¹ and A ² It is preferable that the mass ratio A ¹ /A ² is 1.5 to 10, which is preferable from the viewpoint of elasticity of foam and creaminess of foam. Specifically, as the fatty acid salt of A ^1, caprylic acid, pelargonic, capric acid, undecanoic acid, lauric there may be mentioned acid, cap roll lane acid, Lin der acid, Raul Lorraine acid, the A ² As fatty acid salts, myristic acid, palmitic acid, margaric acid, stearic acid, isostearic acid, arachinic acid, behenic acid, oleic acid, linoleic acid, linolenic acid, ricinoleic acid, arachidonic acid, myristoleic acid, palmitoleic acid, Salts of petroseric acid, elaidic acid, petrolatum acid, gondophosphoric acid, and erukaic acid are mentioned. In addition, salts such as palm oil fatty acids, which are mixtures of lauric acid, myristic acid, palmitic acid, and capric acid, may be mentioned.

From the viewpoint of foaming, creaminess, and freshness, the combination of potassium laurate and a fatty acid salt selected from potassium myristic acid, potassium palmitate, potassium stearate, potassium isostearate and potassium oleate, and potassium palm oil fatty acid are preferred. And, the combination of potassium laurate and potassium myristic acid or potassium palmitate is more preferable. In addition, the method of obtaining the component (A) is not particularly limited, and can be appropriately selected depending on the purpose.

If it is less than 3% by mass, the elasticity and creaminess of the foam are deteriorated, and the fresh feeling is lowered. On the other hand, when it exceeds 10 mass %, the slipperiness at the time of rinsing becomes strong, and the rinsing time becomes long. From the point of foaming and rinsing time, 4 to 8% by mass, particularly 4 to 7% by mass is more preferable.
