Description

  The present invention relates to a detergent composition, and more specifically, foaming property, foam quality, which is a mixture of a polymer compound having a specific sol-gel transition temperature when specified as an aqueous solution, a specific surfactant and water. The present invention relates to a detergent composition having foam, good detergency and usability.

  Conventionally, in order to obtain a high cleaning power, foamability and foam quality, and a good feel after use, various types of cleaning compositions have been studied for cleaning compositions. Formulation development using amino acid-based detergents has been made to reduce the feeling of hair stiffness and skin tightness after use.

  So far, a liquid detergent composition containing an N-acyl neutral amino acid as an amino acid detergent has been reported (Patent Document 1). This product was not practical because it was not very stable.

  Further, a liquid detergent composition for body containing an amide amino acid type amphoteric surfactant or an aminoacetic acid betaine type amphoteric surfactant as an amino acid type detergent has been reported (Patent Document 2). The amount of amphoteric surfactant used in this product is limited, and if it is removed, the degreasing power and sliminess will be severe, the stability and foam quality will deteriorate, and the foaming power will be insufficient. There wasn't.

  Furthermore, a detergent composition containing N-long chain acylalanine as an amino acid detergent has been reported (Patent Document 3). Although this product has good foam quality, good detergency, and low irritation, the amount of N-long chain acylalanine used is limited, and if it is removed, the squeaky feeling at the time of washing is severe and the smoothness is reduced. Was not practical because it was slimy after washing and was also irritating.

  Furthermore, a detergent composition containing a glycine derivative as an amino acid detergent has been reported (Patent Document 4). This product is not practical because the amount of glycine derivative used is limited, and if this amount is deviated, irritation occurs, foaming power is insufficient, and foam breakage deteriorates.

As described above, the conventional amino acid-based detergents can provide a feeling of firmness of the skin after use, smoothness of hair, and suppleness, but have sufficient foaming properties, foam quality, foam retention and cleaning effects. However, the cleaning composition was not always satisfactory.

  Therefore, the present invention is excellent in foaming property, foam quality, and foam retention, has a high cleaning effect, has no sliminess characteristic of a polymer, has a moist feeling after use, and does not feel hairy. An object of the present invention is to provide a detergent composition that is excellent in flexibility.

  As a result of diligent research to solve the above-mentioned problems, the present inventors have found that a high-molecular compound having a specific sol-gel transition temperature in the case of an aqueous solution is blended with an amino acid-based anionic surfactant and water. The present inventors have found that the composition can solve the above-mentioned problems and have completed the present invention.

That is, the present invention includes the following components (A) to (C),

(B) Amino acid-based anionic surfactant (C) Water-containing detergent composition.

  The cleaning composition of the present invention contains a polymer compound having a specific sol-gel transition temperature when it is used as an aqueous solution, so that it has good fluidity when picked up by hand and then hot water. At the same temperature and body temperature, a foam with a resilient structure is formed, the foam structure is maintained for a long time, and it can blend well with dirt, so conventional amino acid anionic surfactants can be used.

Furthermore, there is no feeling of wetness after washing, moist feeling of the skin after use, hair stiffness It is excellent in suppleness and suppleness.

  Therefore, the cleaning composition of the present invention can be suitably used for cleaning skin and hair.

  In this specification, the lower critical solution temperature (LCST) means that a polymer is dissolved in water at a temperature lower than this temperature and becomes a transparent solution, but becomes insoluble at a temperature higher than this temperature. The temperature at which the solution becomes cloudy or precipitates and the phases are separated.

  Block copolymer or graft copolymer in which a plurality of polymer portions having a LCST higher than 0 ° C. and lower than 37 ° C. and a hydrophilic polymer portion are contained as component (A) in the cleaning composition of the present invention A polymer compound whose aqueous solution has a sol-gel transition temperature at a temperature higher than 0 ° C. and lower than 37 ° C. (hereinafter referred to as “temperature-responsive polymer compound”) is a sol-gel inherent in the aqueous solution. It has a transition temperature, and is sol-like with fluidity at a temperature lower than the sol-gel transition temperature, but has a property of losing fluidity and gelling at a temperature higher than the sol-gel transition temperature. Such a temperature-responsive polymer compound is a known compound, and for example, is described as a polymer compound having a sol-gel transition temperature in Japanese Patent No. 3585309. The temperature-responsive polymer compound can also be produced in accordance with Examples 1 to 6 of this Japanese Patent No. 3585309 and other descriptions.

  The temperature-responsive polymer compound includes a plurality of polymer portions having an LCST higher than 0 ° C. and lower than 37 ° C. (hereinafter sometimes referred to as “LCST polymer portion”). The LCST polymer portion includes a polymer having temperature responsiveness that exhibits LCST behavior. The polymer having temperature responsiveness showing the LCST behavior includes poly N-substituted acrylamide derivatives, poly N-substituted methacrylamide derivatives and copolymers thereof, polypropylene oxide, copolymerization of propylene oxide and other alkylene oxides. Examples thereof include a coalescence, polyvinyl methyl ether, polyvinyl alcohol partial acetylated product, and polyalkylene oxide. More specifically, poly-N-acryloylpiperidine, poly-Nn-propylmethacrylamide, poly-N-isopropylacrylamide, poly-N, N-diethylacrylamide, poly-N-isopropylmethacrylamide, poly-N -Cyclopropylacrylamide, poly-N-acryloylpyrrolidine, poly-N, N-ethylmethylacrylamide, poly-N-cyclopropylmethacrylamide, poly-N-ethylacrylamide, etc., and especially poly-N-isopropylacrylamide Preferably used.

  The LCST polymer portion may be a homopolymer composed only of the polymer having LCST, or may be a copolymer copolymerized with another monomer. As other monomers constituting such a copolymer, both hydrophilic monomers and hydrophobic monomers can be used.

  Examples of the hydrophilic monomer include N-vinylpyrrolidone, vinylpyridine, acrylamide, methacrylamide, N-methylacrylamide, hydroxyethyl methacrylate, hydroxyethyl acrylate, hydroxymethyl methacrylate, hydroxymethyl acrylate, and acrylic acid having an acidic group.

  The LCST polymer portion constituting the temperature-responsive polymer compound has an LCST in a range higher than 0 ° C. and lower than 37 ° C. When the LCST polymer portion is a homopolymer, a polymer having an inherent LCST temperature in the range of 0 to 37 ° C. such as poly-N-isopropylacrylamide or poly-Nn-propylmethacrylamide is appropriately selected. be able to. On the other hand, when the LCST polymer portion is a copolymer, it is generally possible to increase the LCST of the copolymer by copolymerizing a hydrophilic monomer with a polymer having LCST, and to co-polymerize a hydrophobic monomer. Since the LCST can be lowered by polymerization, a combination of monomers to be copolymerized with a polymer having temperature responsiveness that exhibits LCST behavior is selected, and a composition ratio or the like is adjusted to 0 to 37. The LCST of the polymer portion can be adjusted in the range of ° C.

  The temperature-responsive polymer compound contains a hydrophilic polymer portion in addition to the LCST polymer portion. Examples of the polymer constituting this hydrophilic polymer portion include polyalkylene oxides such as methyl cellulose, dextran, polyethylene oxide, and polypropylene oxide, polyvinyl alcohol, poly N-vinyl pyrrolidone, polyvinyl pyridine, polyacrylamide, polymethacrylamide, Poly N-methylacrylamide, polyhydroxymethyl acrylate, polyacrylic acid, polymethacrylic acid, polyvinyl sulfonic acid, polystyrene sulfonic acid and their salts, poly N, N-dimethylaminoethyl methacrylate, poly N, N-diethylaminoethyl methacrylate, Examples thereof include poly N, N-dimethylaminopropyl acrylamide and salts thereof.

  Furthermore, the temperature-responsive polymer compound is a block copolymer or graft polymer in which the LCST polymer part and the hydrophilic polymer part are bonded. In the case of a graft polymer, even if the LCST polymer part is a main chain and the hydrophilic polymer part is bonded as a side chain, the main chain is a hydrophilic polymer part and the LCST polymer part is a side chain. It may be combined.

  The block copolymer of the above-mentioned LCST polymer part and hydrophilic polymer part, for example, introduces a plurality of reactive functional groups (hydroxyl group, carboxyl group, amino group, isocyanate group, etc.) in advance and chemistry of both. It can be obtained by bonding by reaction. For example, by introducing a methacryloyl group which is a polymerizable functional group into both ends of polyethylene oxide which is a hydrophilic polymer, and copolymerizing with N-isopropylacrylamide which is a monomer constituting a polymer having LCST, poly- A block copolymer of an LCST polymer portion composed of N-isopropylacrylamide and a hydrophilic polymer portion composed of polyethylene oxide can be obtained.

Thus, a block copolymer of an LCST polymer portion composed of poly-N-isopropylacrylamide and a hydrophilic polymer portion composed of polyethylene oxide can be obtained.

  Further, the graft copolymer of the polymer part having the LCST and the hydrophilic polymer part can use a usual graft polymerization method, a method using a chain transfer reaction of the polymer, and free to the backbone polymer. From the viewpoint of controlling the degree of polymerization of the side chain, it is possible to use a method of introducing a functional group capable of splitting into a group and starting polymerization from the functional group, a method of starting ionic polymerization from a trunk polymer, etc. Introducing one polymerizable functional group into the LCST polymer part and copolymerizing with a monomer that gives the hydrophilic polymer part, or introducing one polymerizable functional group into the hydrophilic polymer part A method of copolymerizing with a monomer constituting the LCST polymer portion is preferably used.
