Description

Solid detergent composition {SOLID DETERGENT COMPOSITION}

Technical field

The present invention relates to a solid detergent composition having good foaming, smooth foaming, softness, meltedness is suppressed, a fresh feeling after washing, excellent manufacturability at 40 to 50 ° C, and a friction inhibiting effect on the skin. It is about.

Prior art

The solid detergent composition is excellent in foaming and a fresh feeling after washing, and is required to be difficult to melt and dissolve during use. As a method of improving foaming, for example, a technique of blending a cationic high molecular compound with a solid detergent based on a higher fatty acid salt has been proposed (Patent Document 1: Japanese Patent Application Laid-Open No. 58-167700). , Patent Document 2: Japanese Patent Application Laid-Open No. 61-190597). However, these techniques have a problem that foaming is insufficient, contains a large amount of a higher fatty acid salt having an unsaturated bond, and also adds a water-soluble high molecular compound, so that it tends to melt and collapse during use.

Moreover, a technique using a combination of a cationic polymer compound and an amino acid synthetic surfactant in combination with a higher fatty acid (see Patent Document 3: Japanese Patent Laid-Open No. 2004-137402), and a lot of short fatty acid higher fatty acid salts A technique using a combination of a high foaming synthetic surfactant, a higher fatty acid and a high molecular compound in a higher fatty acid salt to be included has been proposed (see Patent Document 4: Japanese Patent Laid-Open No. 2003-64400). However, in these techniques, since 1 mass% or more of surfactants other than fatty acid salts are used for the purpose of the improvement of foaming, easiness of rinsing and a fresh feeling after washing | cleaning are inadequate, and at normal 40-50 degreeC In normal manufacture, there exists a problem that mold release property and soap dough release property are bad.

From the above, the solid detergent composition which foams are good, foams are smooth and soft, and is excellent in the sensation after washing and the manufacturability in 40-50 degreeC is desired.

MEANS TO SOLVE THE PROBLEM As a result of earnestly examining in order to achieve the said objective, this inventor is (A) following General formula (1) which is a base of a solid detergent.

R ¹ COOM (1)

(Wherein R ¹ represents a monovalent hydrocarbon group having 5 to 21 carbon atoms. M represents an alkali metal atom, an alkaline earth metal atom, ammonium, an amine or a basic amino acid.)

Fatty acid salt, its fatty acid composition, R ¹ is a carbon number of 13 monovalent hydrocarbon group, a fatty acid is more than 35% by mass or less, and R ¹ is equal to or less than the first having an unsaturated bond is a hydrocarbon group fatty acids 35% by weight fatty acid salt represented by the And (B-1) The copolymer containing (i) dimethyldiallyl ammonium chloride and (ii) (meth) acrylic acid as a structural unit, The molar ratio of (i) / (ii) is 95/5-54 / 46 phosphorus copolymer, (B-2) (meth) acrylamide propyl trimethylammonium chloride, (meth) acrylic acid, (meth) acrylic acid methyl copolymer, (B-3) chloride (meth) acrylamide propyl trimethyl ammonium (meth) 1 mass% of surfactants other than fatty acid salts when a polymer selected from the group consisting of an acrylic acid (meth) acrylamide copolymer and a (B-4) dimethyldiallyl ammonium chloride homopolymer is used in a specific amount, respectively. Even if I do not mix it up, foaming is good, It was found that the product was smooth and soft, was excellent in the fresh feeling after washing, and the dissolution was significantly improved compared with the conventional one.

Moreover, there exist some incompatibility in the manufacturing process in the technique which uses 1 mass% of fatty acid salts and surfactant other than fatty acid salts together. One is that the stickiness of soap dough increases, so that mold release and mold release of soap dough worsens during mold process. For the improvement, brine or the like is applied to the surface of the soap, which has the drawback of promoting the aging of the manufacturing equipment. Another is the difficulty of controlling the soap temperature. Generally, the soap temperature at the time of soap manufacture is 40-50 degreeC, but this property worsens mold release property from a metal mold | die. In order to solve this problem, it is also possible to lower the kneading temperature as described in Patent Document 4, but the manufacturing efficiency is lowered because the manufacturing speed is slowed so that heat energy is hardly generated during kneading. Since it is necessary to raise the cooling efficiency of the apparatus, it is necessary to correspond to equipment such as separately adding a cooling supply device having high capacity.

On the other hand, since the solid detergent composition containing many fatty acid salts of short chain length improves foamability, and becomes a foam of large bubble, especially when a resin towel like a nylon towel is used, the skin at the time of washing It was discovered that the cushioning between the foam and the foam was weak, so that the friction was felt strongly, and the pain was felt when rubbed too strongly. Those with weak skin, those with abnormalities in parts of the skin, such as wounds or inflammation, those who have difficulty washing the body skillfully, such as infants who have started to wash their bodies, or those who are uncomfortable with parts of the body due to dementia or accidents. Etc., it is thought that it may lead to deterioration of the skin condition because it rubs too strongly at the time of washing.

The present invention is excellent in the manufacturability at 40 to 50 ° C and economically produced by using (A) a fatty acid salt having a specific fatty acid composition and (B) a specific polymer, and can be produced economically and friction against skin. It has been found that a solid detergent composition having an inhibitory effect (particularly when a nylon towel or the like is used) can be provided. It has been achieved to achieve the present invention. In addition, as a result of further investigation, when the fatty acid is blended, it is found that the foam performance is further improved, and the present invention has been achieved.
