Description

[Detailed description of the invention]

The present invention relates to novel detergent compositions, particularly, but not exclusively, foaming liquid compositions useful for light cleaning such as hand washing of dishes. The composition can also be used for fabric washing, carpet cleaning and shampooing.

[L anti-525 J Is it suitable for cleaning the snack bowl? High quality liquid detergent compositions are known. Many of the commercially available formulations are based on anionic detergents of the sulfate or sulfonate type, especially alkyl sulfates, alkyl benzene sulfonates and alkanesulfonates in combination with alkyl polyethoxy sulfates (alkyl ether sulfates). Sulfonate-type detergents generally predominate. The use of conventional dishwashing liquids based on alkylbenpine sulfonates/alkyl ether sulfates or alkyl sulfates/alkyl ether sulfates is
It is known to cause rough hands of the user. Therefore, hypoallergenicity of detergent products, especially dishwashing liquids, has become a desirable property of such products. Alkyl mono-glycosides and alkyl poly-glycosides are known and have been described in numerous prior patents and publications. For example, Boettner (U.S. Pat. No. 32
No. 19656) discloses that alkyl mono-glycosides are effective as foam stabilizers for anionic and nonionic surfactants. L evt (U.S. Patent No. 37722
No. 69) discloses the use of decyl glucoside containing less than 1.6 g of glucose units as a good blowing agent. Some disclosures of PrOcter & Gamble (
For example, E P O070074, E P O0
No. 70075, EP 070076) discusses the effectiveness of acrylic polyglucosides containing 1.5 or more glycose units in detergent compositions. Japan enke 1 (EP 216301A”) is 1~
It is disclosed that an alkyl glycoside having 1.4 glucose units can be used effectively in a dishwashing liquid containing ether sulfate and ethanolamide. TECHNICAL FIELD The present invention relates to a safe, low-irritant, detergent based on alkyl polyglycosides, which has good foam stability and good cleaning ability. It is an object of the present invention to provide a novel highly foaming liquid detergent containing an ionizing agent.Furthermore, it is an object of the present invention to provide a liquid detergent that is harmless to the environment and has low irritation. The composition relates to an aqueous liquid detergent composition comprising: (a) a C8-018 alkyl polyglycide surfactant having an average degree of polymerization of 1 to 3; (b) an anionic surfactant; and (c) an interfacial surface active agent. In this composition comprising active betaine and/or amine oxide, and optionally (d) ethanolamide, the number of anionic active agents exceeds 1.5 times (on a molar basis) the content of betaine and/or amine oxide. Alkyl polyglycosides are non-ionic in nature, but they have different types of hydrophilic groups, such as alkyl ethoxylates or alkylphenol ethoxylates. compared to conventional ethoxylated non-ionic agents, and thus compared to conventional ethoxylated non-ionic agents.
Exhibiting different physical, chemical, and functional properties. For example, ethoxylates are low melting solids or liquids at room temperature, are completely miscible in nonpolar solvents, and their aqueous solutions have a D temperature. In comparison, alkyl polyglycosides are high-melting solids with poor solubility in non-polar solvents;
Its aqueous solution shows no cloud point. Also, compared to similar conventional non-ionic agents, furkyl polyglycosides generally produce lower surface tensions and more stable foams. Furthermore, alkyl polyglycosides are produced in different ways,
It can be manufactured using only natural raw materials. Therefore,
Compounds and compositions made from alkylpolyglycosides are expected to be biologically safer and more acceptable than conventional nonionic agents and compositions containing them. The impurities present will also be different from conventional nonionic agents. Alkyl polyglycoside is the F 1s of detergent alcohol.
It can be produced by cher glycosidation. For example, 08-C18 alcohol (ROH) + r glucose" (
G) Ten catalyst → ROG + H20 × ROGx The details of the product depend on the adjustment of the ratio of reactants. Certain products are, for example, ROGl:ROG2:RO
This will be the ratio of G3. The alkyl polyglycosides used in the present invention have a hydrophobic group containing approximately 8 to 20 carbon atoms, preferably about 10 to about 16 carbon atoms, most preferably 12 to 14 carbon atoms, and about 1 to about 3 saccharide units. , preferably 1 to 1.5, most preferably 1.2 to 1.4 on average. In the example of "Satsukarido" knit and No. 1,
Galactoside, glucoside, fructocyto or glycodyl. Mixtures of these can also be used. A preferred alkyl polyglycoside is Horizon. The average degree of polymerization of APG500 is 1.4, and APG
550 is 1,8. U.S. Patent No. 4,599,188 (
L 1enadO) further describes and characterizes alkyl polyglycosides. It is preferable that the alkyl polyglycoside is the main active ingredient, for example, preferably accounts for 30 to 60% of the active ingredient. The co-active anionic surfactants used according to the invention are of the sulfate or sulfonate type, or mixtures thereof. The sulfate can be a conventional anionic synthetic detergent or an alkanol (i.e. n=o)
Alternatively, it may be an ethoxylated alkanol sulfate hemiester. Suitable sulfates are obtained from ethoxylated or unethoxylated linear, branched, primary or secondary alcohols. Preferred alcohols are as follows. linear primary alcohols containing up to 12 moles of ethylene oxide per mole of alcohol. (ii) predominantly linear, containing 10 to 15 carbon atoms and about 25% 2-methyl branchiho, and up to 12 moles of ethylene oxide per mole of alcohol if ethoxylated; First alcohol. (iii) Random secondary alcohols containing 11 to 15 carbon atoms and 7 to 30 moles of ethylene oxide per mole of alcohol. Substantially branched primary alcohols may also be used. The cations that neutralize the anionic surfactants are preferably sodium and ammonium, the latter sulfates being able to promote the drotropes of the liquid compositions of the invention. Sulfonate is a linear alkylbenzene sulfonate,
Conventionally used sulfonates such as secondary alkyl sulfonates and alpha olefin sulfonates may be used. Amine Oxide/Betaine A third important feature of the present invention is the presence of an amine oxide or betaine as a foam enhancer. For reasons of economy and, of course, cost-effectiveness, it is preferred to avoid the use of amine oxides or betaines, particularly about 1% of the amine oxide. Preferably, the amine oxide content does not exceed 10% by weight of the active detergent mixture. Also, 41 for betaine is 30 for this mixture! It is desirable that the content does not exceed m%. The total amount of amine oxide and betaine is 12-30% by weight of the active detergent mixture. The foaming enhancer is preferably included in an amount of 2 to 6 times the total acid composition. Preferably, only betaine is used. Suitable betaines include simple betaines of the formula % and amidobetaines of the formula C3 hydroxyalkyl. An example of stafobetaine is -CO of the formula above.
The formula is obtained by replacing CO2 with the following form: -(cH2)3S03 or -CH2-Cll5II2S

Foaming performance was evaluated using the Achter-D 1erkcs test. 100 d of an aqueous solution of each test material containing 0.04% active detergent in water with a hardness of 24°H (French hardness) at a temperature of 45°C was added to a graduated chamber using a vertically vibrating perforated disc. (containing 95 parts of commercially available cooking fat, 120.25 parts of olein 1i, 25 parts of stearin@0°, and 10 parts of wheat starch in 120 parts of water) was added in an increasing amount (0,i) until the bubbles disappeared. Additions were made at 15 second intervals (10 seconds of gentle stirring and 5 seconds of stopping). Results were recorded as number of stain increments (NSI score). Score differences of 6 or more are generally considered meaningless. Each outcome typically averaged 3-4 points. Several in vitro or in vivo methods for evaluating the protein denaturing ability of surfactants and their mixtures have been reported (Miyazawa et al., I.
ntJ Cos Sci, 6.33-46.1
984 and papers cited therein). One such method is the use of small acid sfactorases obtained from the skin (263-273, 1984) or small acid sfactorases (Tanaka et al., Anal.

) and detergents. In vivo-? f' irritation can be evaluated using the Nex wash test. In this punishment test, the undiluted product was applied to the subject's arms and legs and washed off. This treatment was repeated 4 times a day for 5 days, and the degree of erythema that appeared on the skin was evaluated by an experienced evaluator. From a comparison of the fist wheat germ phosphatase test (WGAP) results and the flex cleaning test results, the test conditions were determined. Formulations that provided enzyme inhibition of less than 50% below were shown to be substantially hypoallergenic. The Flex Wash Test showed no detectable difference in hypoallergenicity between products providing inhibition of less than 40. This test shows that enzyme tests are very sensitive;
In actual living conditions, it has become clear that below that level, any active agent or product is equally hypoallergenic, and that there is a limit level for protein degeneration. WGAP test results indicate % inhibition (i.e.
(remaining amount after subtracting % activity from 100%). Water did not provide any inhibition, ie 100% activity remained. i plate and 1 APG: Ho
