Description

[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a cleaning composition that does not cause "sliminess" during cleaning and has good rinsing properties. Conventional technology Cleaning agents such as kitchen cleaners, household detergents, shampoos, and body shampoos inevitably come into contact with the skin of hands and other surfaces during cleaning, so cleaning agent compositions that are milder to the skin have been considered. . However, with conventional cleaning agents, the surfactant adsorbs to the skin and hard surfaces, making them feel ``slimy'' and not only does it feel unpleasant to use, but in order to remove that ``slimy'' feeling, large amounts of water are used to remove the ``slimy'' feeling. Since rinsing was required, there were major problems in terms of workability and economy. Problems to be Solved by the Invention The present invention provides a cleaning composition for hard surfaces, skin, and hair that has low adsorption of surfactants to hard surfaces and skin and has good rinsability. . The present invention also provides a cleaning composition that has excellent rinsability, rich lathering, and creamy feel. Structure of the Invention The present invention provides a hard surface cleaning composition, a skin cleaning composition, and a hair cleaning composition (shampoo), which are characterized by containing the following components (a) and (b). be. (a) Sugar ester surfactant consisting of an ester of a C _6-18 fatty acid and a C _5-6 monosaccharide or its monoalkyl ether: 1 to 30% by weight. (b) Higher alcohol sulfate ester salt, amino acid surfactant, C _10-18 α-olefin sulfonate, succinate ester salt or polyoxyethylene alkyl ether sulfate, and the salt is an alkali metal, magnesium or , a surfactant that is a di- or triethanolamine salt, or a polyoxyethylene alkyl ether obtained by adding an average of 2 to 15 moles of ethylene oxide to a C _10-18 primary or secondary alcohol with a linear chain ratio of 50% or more. At least one selected surfactant: 0.5-20% by weight. The present invention also provides, in addition to the above components (a) and (b),
The cleaning composition further contains the following component (c). (c) Cationized cellulose: 0.1 to 2% by weight. The present invention will be explained in more detail below. The sugar ester surfactant of component (a) is a surfactant that is mild to the skin with little skin irritation.
Obtained from _C6-18 fatty acids or fatty acid derivatives such as esters of these fatty acids and monopentoses, monohexoses or their monoalkyl ethers. Here, fatty acids, whether saturated or unsaturated,
Moreover, it may be a straight chain or may have a branch. Specific examples of such fatty acids include caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, caproleic acid, lauroleic acid, myristoleic acid,
Examples include palmitoleic acid, oleic acid, and methylundecanoic acid. Further, as fatty acid derivatives, fatty acid esters of the above-mentioned fatty acids and lower alcohols are used, and examples thereof include methyl esters, ethyl esters, propyl esters, etc. of the above-mentioned fatty acids. Examples of monopentoses include monopentoses such as xylose, arabinose, ribulose, xylulose, and lyxose, as well as monoalkylated products such as methylxylose and ethylarabinose. Examples of monohexoses include monohexoses such as glucose, galactose, and fructose, as well as monoalkylated products such as methylglucose and ethylglucose. In the sugar ester surfactant of the present invention, it is not particularly important how many of the hydroxyl groups of the monosaccharide form esters with _C6-18 fatty acid residues, but it is preferable that the surfactants are mainly monoesters. It is desirable that the amount of polyester of ester or higher is 1% by weight or less. The sugar ester surfactant as component (a) is contained in the detergent composition of the present invention in an amount of 1 to 30% by weight, preferably 5 to 30% by weight.
Contains 25% by weight. If this amount is too small, the occurrence of "slimy" cannot be sufficiently prevented, and the rinsing performance deteriorates. On the other hand, even if the blended amount is increased,
No improvement in cleaning performance is observed, and system stability also deteriorates. The sugar ester surfactant as component (a) can be obtained by an appropriate method, but according to the method for producing sugar monofatty acid esters described in JP-A No. 3-76593, sugars mainly composed of monoesters can be obtained. Esters can be advantageously synthesized industrially. (b) Ingredients include the following (b-1) to (b-6)
Surfactants selected from the following may be used alone or in combination of two or more. As the salts of these surfactants, alkali metal, agnesium, or mono-, di-, or triethanolamine salts are used. (b-1): Higher alcohol sulfate ester salt (alkyl sulfate). The number of carbon atoms in the alcohol chain length is 8 to 20
is suitable. Further, the alcohol moiety may be linear or branched, and may be saturated or unsaturated. (b-2): Amino acid surfactant. Specific examples thereof include acylated alaninate salts, acylated sarcosinate salts, acylated tauride salts, acylated glutamate salts, aminoacetic acid betaines, and sulfobetaines. (b-3): C _10-18 α-olefin sulfonate. (b-4): Succinic acid ester salt. It is a salt of a monoester of succinic acid and alcohol represented by the following general formula, and the carbon number of R is preferably C8 _{to C16} . X represents salt. Disodium polyoxyethylene lauroyl sulfosuccinate and the like can also be used. (R ₁ : Hydrogen, alkyl group or alkenyl group R ₂ , R ₃ : Either one is an alkyl group, and the other is hydrogen, an alkali metal, or an alkaline earth metal.
or both hydrogen, alkali metals, alkaline earth metals or alkanolamines. ) (b-5): Polyoxyethylene alkyl ether sulfate. Sodium polyoxyethylene C ₁₃ alkyl ether sulfate (same as C ₁₃ higher alcohol polyoxyethylene sulfate sodium)
(Linear chain rate: 40%, = 5 is the average number of added moles of ethylene oxide), polyoxyethylene lauryl ether sodium sulfate (= 3), etc. (b-6): Polyoxyethylene alkyl ether.
An average of 2 to 15 moles (=2 to 15), preferably 7 to 15 moles of ethylene oxide is added to a primary or secondary alcohol having a linear chain ratio of 50% or more, preferably 70% by weight or more. Alcohols can be saturated or unsaturated. Component (b), the surfactant, is present in the detergent composition at a concentration of 0.5%.
-20% by weight, preferably 5-15% by weight. If this amount is too large, the occurrence of "slimy" cannot be sufficiently prevented and the rinsing performance deteriorates. The cleaning composition of the present invention may contain various optional ingredients depending on its use, such as anionic surfactants, nonionic surfactants, cationic surfactants,
Amphoteric surfactants, sequestering agents, hydrotropes, thickeners, bactericidal agents, preservatives, pigments, fragrances, and the like can be blended as appropriate. The cleaning composition containing components (a) and (b) of the present invention can be used as a cleaning agent for hard surfaces, skin, and hair, but in particular, it can be used to clean skin such as hands, skin, and scalp. Suitable for applications in which the agent composition comes into contact with the product and for cleaning hard surfaces such as tableware, tiles, and glass; for example, skin cleansers such as shampoo and body shampoo, kitchen detergents, and residential use for baths and toilets. Suitable for cleaning etc. In addition, by using the surfactants (a) and (b) of the present invention together, and further adding 0.1 to 2% by weight of cationized cellulose as the (c) component, in addition to good rinsability, A detergent composition having rich foaming and creamy foam feel can be obtained. The use of this cleaning composition is not particularly limited, but it is suitable as a shampoo composition. This cleaning composition preferably contains both components (a) and (b) of the present invention in a weight ratio of (a)/(b) = 9/1 to 4/6.
