Description

  The present invention relates to a liquid detergent composition that is filled in a former container that is moist and washable, has a flexible foam quality, and has excellent stability.

  According to Patent Document 1, a detergent using an N-acylglycine salt and an imidazolinium betaine-type amphoteric surfactant is proposed that has low hand roughness, foaming, and excellent detergency. The thing which exhibits a high antiseptic effect, without mix | blending an agent is proposed.

  In order to obtain uniform and sufficient foam, a liquid detergent composition using a pump former or a squeeze foamer has been proposed.

  For example, Patent Document 3 contains an N-acylamino acid anion activator, a soap having a Kraft point of 20 ° C. or higher, a polyhydric alcohol, and a polyoxyethylene alkyl ether, has a creamy and elastic foam, and has a low temperature. There has been proposed a detergent composition in a former container which is excellent in stability and gives a moist skin feel after washing.

  Patent Document 4 contains a polyoxyethylene alkyl ether type nonionic surfactant, a linear or branched higher fatty acid salt having 8 to 16 carbon atoms, a polyhydric alcohol having 3 to 6 carbon atoms, and water, and is not clogged. A liquid detergent composition is proposed that is fine in texture, has a highly resilient foam, is excellent in long-term storage stability, has a good feel after washing, and is optimal for a pump former.

  In Patent Document 5, an ionic surfactant and a polyhydric alcohol are adjusted to a specific ratio, and 90% by weight or more of the ionic surfactant is occupied by a higher fatty acid soap having 5 to 25 carbon atoms, and is contained in the polyhydric alcohol. It has been proposed that a cleaning composition for a pump former in which the amount of propylene glycol to be produced is less than 20% by weight with respect to the whole composition is excellent in foaming property and foam quality, and also has excellent washout properties.

  In Patent Document 6, a liquid detergent composition for filling a pump former container in which an acylamino acid triethanolamine salt, a hydroxyalkyl polyhydric alcohol ether compound and amidopropyl betaine laurate are adjusted to a specific ratio is sufficiently safe and sufficient. Proposals have been proposed that produce a foam with a cleaning effect and a good feeling of use and are less likely to cause clogging of the pump even during long-term use.

JP-A-10-219285 JP 2003-226636 A Japanese Patent No. 4527655 JP2015-107927A Japanese Patent No. 5373216 Japanese Patent No. 4558514

  However, Patent Documents 1 and 2 cannot be used because they are clogged in the former container, and when foaming is insufficient, the surfactant is used at a high concentration, which is not necessarily safe for the skin.

Even in the proposals of Patent Documents 3 to 6 using a former container, there is room for improvement in order to combine moist feeling after washing, elastic foam quality, low temperature and high temperature stability.

  Therefore, the problem to be solved by the present invention is to provide a liquid detergent composition that is filled in a former container that is moist and has an elastic foam quality and excellent stability.

Means for Solving the Invention

  In order to solve the above-mentioned problems, the present inventors have intensively studied, and as a result, provide a liquid detergent composition that is filled in a former container that is moisturized and has an elastic foam quality but excellent stability. It came to.

  That is, the present invention comprises (A) 1 to 10% by weight of an acylamino acid surfactant, (B) 0.01 to 10% by weight of an imidazolinium betaine type surfactant, and (C) 10 to 10%. A liquid detergent composition containing 60% by weight of a polyhydric alcohol and discharged in a former container is provided.

Effect of the invention

Hereinafter, the present invention will be described in detail.
The (A) acylamino acid surfactant used in the liquid detergent composition of the present invention is a highly safe cleaning component made from an amino acid and a fatty acid. In particular, N-coconut oil fatty acid acylglycine salt is preferable, and sodium or potassium is preferable as a counter salt. Commercially available products can be used such as amylite GCS-12K (manufactured by Ajinomoto Co., Inc.) and N-coconut oil fatty acid acylglycine potassium aqueous solution, which are marketed as sodium N-coconut oil fatty acid acylglycine sodium aqueous solution. Amylite GCK-12K (Ajinomoto Co., Inc.) can be used.

  These acylamino acid surfactants can be used alone or in combination of two or more.

  The blending amount of the (A) acylamino acid surfactant in the liquid detergent composition of the present invention is 1 to 10% by weight, preferably 3 to 7% by weight. If it is less than 1% by weight, the washability is poor, and if it exceeds 10% by weight, a load is applied to the pump former container.

  The (B) imidazolinium betaine type surfactant used in the liquid detergent composition of the present invention is preferably N-lauroyl-N′-carboxymethyl-N′-hydroxyethylethylenediamine sodium, softazoline LHL (manufactured by Kawaken Fine Chemicals). ) Has been marketed as an aqueous solution.

  The blending amount of (B) imidazolinium betaine type surfactant in the liquid detergent composition of the present invention is 0.01 to 10% by weight, preferably 0.1 to 5% by weight. If it is less than 0.01% by weight, the foam quality becomes coarse, and if it exceeds 10% by weight, the wash-up becomes dull.

  The ratio of (A) acylamino acid surfactant to (B) imidazolinium betaine surfactant in the liquid detergent composition of the present invention is preferably 0.5 <(A) / (B) <5.5, preferably The stability is further improved by satisfying 1.0 <(A) / (B) <3.0. When the ratio is less than 0.5, the low temperature stability is poor, and when it exceeds 5.5, the high temperature stability is deteriorated.

  The polyhydric alcohol (C) used in the liquid detergent composition of the present invention can be selected from those usually blended in cosmetics and the like, and is not particularly limited. For example, concentrated glycerin, diglycerin, propylene glycol , Dipropylene glycol, propanediol, 1,3-butylene glycol, pentylene glycol, 1,2-hexanediol, sorbitol and the like.

  The above polyhydric alcohols can be used alone or in combination of two or more. Preferably, foam quality is improved by combining concentrated glycerin, diglycerin, dipropylene glycol, 1,3-butylene glycol, and sorbitol. , Moisturizing after washing.

  The compounding quantity of (C) polyhydric alcohol in the liquid cleaning composition of this invention is 10 to 60 weight%, Preferably it is 25 to 45 weight%. If it is less than 10% by weight, the wash-up is not moist, and if it exceeds 60% by weight, the foam quality tends to deteriorate.

  In addition to the components described above, the liquid detergent composition of the present invention can be appropriately mixed with other components as long as the object of the present invention is not impaired. For example, anionic surfactants, cationic surfactants, amphoteric surfactants, nonionic surfactants, oils, silicones, water-soluble polymer compounds, powders, preservatives, bactericides, pH adjusters, antioxidants, Examples include sequestering agents, ultraviolet absorbers, sugars, fragrances, salts, and clay minerals. These 1 type (s) or 2 or more types can be selected arbitrarily and can be mix | blended.

  The liquid detergent composition of the present invention is prepared as a liquid aqueous preparation according to a conventional method, and can be used in the same manner as the liquid detergent composition used in conventional pump formers and squeeze foamers. It can be used as soap, body soap, shampoo and the like.

  Hereinafter, the present invention will be described in more detail with reference to specific examples. However, the present invention is not limited to the following examples. Moreover, unless otherwise indicated, the compounding quantity in a following example and a comparative example shows weight%.
