Description: BACKGROUND OF THE INVENTION Field of the Invention : This invention relates to a low-irritation detergent composition, and, more particularly, to a low-irritation detergent composition comprising an alkyl saccharide-type surface active agent and a cationic polymer. The composition is a low irritant to the skin and hair, produces excellent creamy foam, possesses a superior hair conditioning effect, and imparts an outstanding moisture feeling to the skin. Description of the Background Nonionic surface active agents are widely used in compositions for use in washing the skin and hair. Although nonionic surface active agents possess the advantage of being only slightly irritating, their foaming capability is not sufficient. Because of this, not much of them are formulated into detergent compositions requiring good foaming capability, such as hair shampoos, body shampoos, and the like. Besides the inferior foaming capability and relatively poor detergent capability, which are experienced when a nonionic surface active agent is used alone in a detergent composition, nonionic surface active agents have a problem of imparting a creaky, crinkle feeling to the hair and the skin. Document GB-A-2 050 166 discloses a composition for a hair treatment comprising a cationic polymer and plant extracts containing a saponing, the use of saponin together with a cationic polymer reduces the defects in the cationic polymer, i.e. the reappearance of greasyness in the hair following the treatment. Development of a stable detergent composition comprising a nonionic surface active agent, which is a low irritant to the skin and hair, possesses sufficient foaming and detergent capabilities, and is able to impart a superior feeling the skin, has been desired. In view of this situation the present inventors have undertaken extensive studies to resolve the above-mentioned problem existing in nonionic surface active agents. As a result, the inventors have found that the combined use of an alkyl saccharide, which is one type of nonionic surface active agent, and a cationic polymer could greatly reduce irritation to the skin and hair, and produce abundant, high quality foam which impart a comfortable slippery feeling to the skin. Such a combined use of an alkyl saccharide and a cationic polymer also provided a detergent composition having an excellent hair conditioning effect and skin moisturizing effect. SUMMARY OF THE INVENTION Accordingly, an object of this invention is to provide a low-irritation detergent composition comprising the following components (A) and (B): (A) at least one alkyl saccharide-type surface active agent represented by formula (I): R₁-O-(R₂O) m -(G) n (I) wherein R₁ represents a linear or branched alkyl group of a C₈₋₁₈ carbon atom content, a linear or branched alkenyl group of a C₈₋₁₈ carbon atom content, or an alkylphenyl group of a C₈₋₁₈ carbon atom content, with the alkyl group being either linear or branched, R₂ represents an alkylene group of a C₂₋₄ carbon atom content, G represents a reduced sugar of a C₅₋₆ carbon atom content, m denotes a value of 0 to 10 and n denotes a value of 1 to 10, and (B) at least one cationic polymer, with the exception of compositions comprising plant extracts containing a saponin. Other objects, features and advantages of the invention will hereinafter become more readily apparent from the following description. DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS As an alkyl saccharide-type surface active agent of formula (I), which is the (A) component of this invention, those having an alkyl group for R₁ with 8 to 18, particularly 10 to 14 (decyl group, lauryl group, myristyl group, etc.), carbon atoms are preferable. The value of m in formula (I) is preferably from 0 to 3, with 0 being particularly preferable. The basic unit for the saccharide portion [G in formula (I)], which is the hydrophilic group of the alkyl saccharide-type surface active agent, is a reducing sugar having a C₅₋₆ carbon atom content. Glucose, galactose, and fructose are named as examples of desirable reducing sugars. The degree of the polymerization (S) of saccharide, i.e., the value of n in formula (I), is 1 to 10. In particular, use of reducing sugars containing 80% or more of those having the degree of the polymerization (S) of 1 to 4 is desirable. The compounds of formula (I) having a lower degree of the polymerization (S), e.g. 1 to 1.4, are desirable. When the property of the compounds of formula (I) due to the group R₁ is taken into account, the value for the polymerization (S) of 1 to 1.4 is desirable for the R₁ group with C₈₋₁₁, and (S) of 1.5 to 4.0 is desirable for the R₁ group with C₁₂₋₁₄. The mean values for (S) were determined by proton-NMR method. Given as specific examples of these alkyl saccharidetype surface active agents are β-alkyl saccharide synthesized by the Koenigs-Knorr method such as octylglucoside, nonylglucoside, decylmaltoside, dodecylmaltoside, tridecylmaltoside and polyoxyethylene (2 E.O.)dodecylglucoside; alkyl saccharide produced from a reduced sugar such as glucose, galactose or maltose, and a higher alcohol, polyoxyethylene or alkylether glycol (US-A-3,219,656, US-A-3,839,318, and US-A-4,223,129). The (A) component is formulated into the detergent composition of this invention in an amount of 1 to 60% by weight. When the composition is a shampoo, an amount of 5 to 20% by weight is desirable. When it is a composition for use with the skin, an amount of 5 to 50% by weight is desirable.

Also, the total of o + p averages between 1 and 3. A substitution value of smaller than 0.01 is unsatisfactory, while if this value is greater than 1 there is no particular problem, but, from the aspect of reaction yield, a value 1 or smaller is more desirable. The molecular weight of the cationic cellulose used here is in the range of about 100,000 to 3,000,000. A desirable cationic starch for use in the present invention should satisfy the following formula (IV): wherein A′ represents a starch residual group, R₇ represents an alkylene group or hydroxyalkylene group, R₈, R₉, and R₁₀ may be the same or different, and represent an alkyl, aryl, or aralkyl group having less than 10 carbon atoms, or may form a heterocyclic ring together with a nitrogen atom in the formula, X′ represents an anion (chlorine, bromine, iodine, sulfuric acid, sulfonic acid, methyl-sulfuric acid, phosphoric acid, nitric acid, and the like.), and l′ is a positive integer.

The molecular weights of copolymers of diallyl quaternary ammonium salt and acryl amide may be in the range from about 30,000 to 2,000,000, but the range from 100,000 to 1,000,000 is particularly preferable.

The molecular weights of the quaternary polyvinyl pyrrolidone derivative may be in the range from about 10,000 to 2,000,000, but the range from 50,000 to 1,500,000 is particularly desirable. The content of the cationic nitrogen derived from the cationic polymer contained in the above-mentioned vinyl polymer is in the range from 0.004% to 0.2% by weight, with the most desirable range being from 0.01% to 0.15% by weight. Below 0.004% the effect is inadequate; above 0.2% the performance is good, but the vinyl polymer becomes colored and the high cost is disadvantageous. Given as a desirable polyglycol-polyamine condensate a compound represented by the following formula (VIII): wherein R₂₂, R₂₄, R₂₅, and R₂₇ represent hydroxyalkylene groups having 2 to 4 carbon atoms, R₂₃ and R₂₆ represent alkylene groups having 2 or 3 carbon atoms, x and y represent integers of 10 to 20, m3 represents an integer of 2 to 4, n3 represents an integer of 2 to 6, r represents an integer of 1 to 50, and R₂₁ represents a linear or branched alkyl group having 6 to 20 carbon atoms. One or more of the above-mentioned cationic polymers are used as the (B) component and are formulated into the detergent composition of this invention in an amount of 0.01 to 5% by weight. When the composition is a shampoo the amount of 0.1 to 1.5% by weight is desirable. When it is a composition for use with the skin the amount of 0.01 to 1% by weight is desirable. It is desirable to adjust the pH of the composition of this invention to 2-10, preferably to 4-8, using an acidic or alkaline pH adjusting agent which is conventionally used in a detergent composition. Besides the above-mentioned essential components, other components which are generally used in detergent compositions may be optionally formulated into the detergent composition of the present invention inasmuch as the effect of the present invention is not affected.
