Definitions

• the present invention relates to a cleaning composition which provides an effective cleaning and shine performance on surfaces, especially hard surfaces.
• compositions which provide cleaned shiny surfaces is a problem known in the art to the formulator of a cleaning composition. More particularly, the problem of providing shiny surfaces is often compromised by residues of the compositions which are left on said surfaces and which appear as streaks as water evaporation is completed. The problem of the residuality is even more noticeable where the composition is used to clean surfaces made of glossy materials, such as glossy ceramic tiles, windows and mirrors, or such materials as polyurethane-coated PVC which is widely used in Northern America. Furthermore, nowadays, many products are formulated or can be used as no-rinse products. In such conditions or with such products, the problem of residuality has become more acute.

• An essential feature of the invention is a surfactant system, said system comprising an amine oxide and a betaine or a sulphobetaine surfactant in specific weight ratios of amine oxide to betaine or a sulphobetaine surfactant.
• Amine oxides to be used herein are compounds corresponding to the formula: R R' R'' N ⁇ O wherein R is a primary alkyl group containing 6-24 carbons, preferably 10-18 carbons, and wherein R' and R'' are, each, independently selected from methyl, ethyl and 2-hydroxyethyl.
• the arrow in the formula is a conventional representation of a semi-polar bond.
• the preferred amine oxides are those in which the primary alkyl group has a straight chain in at least most of the molecules, generally at least 70%, preferably at least 90% of the molecules, and the amine oxides which are especially preferred are those in which R contains 10-18 carbons and R' and R'' are both methyl.

• a most preferred amine oxide for use herein is N-decyldimethylamine oxide.
• composition according to the present invention comprises a betaine or a sulphobetaine surfactant, or derivatives thereof, or mixtures thereof.
• a further advantage of the invention is the mild action profile of said betaine and/or sulphobetaine surfactants. Accordingly, the compositions herein may be particularly suitable for the cleaning of delicate surfaces, e.g. delicate laundry or surfaces in contact with food and/or babies. Furthermore, betaine and/or sulphobetaine surfactants are also extremely mild to the skin, and thus contribute to the convenience of use of the compositions of the present invention by the user.
• Suitable betaine/sulphobetaine surfactants to be used in the compositions of the present invention are the betaine/sulphobetaine and betaine-like detergents wherein the molecule contains both basic and acidic groups which form an inner salt giving the molecule both cationic and anionic hydrophilic groups over a broad range of pH values.
• Some common examples of these detergents are described in U.S. Pat. Nos. 2,082,275, 2,702,279 and 2,255,082, incorporated herein by reference.
• Preferred betaine or sulphobetaine surfactants have the formula wherein R1 is an alkyl radical containing from about 1 to about 24 carbon atoms, preferably from 8 to 18, and more preferably from 12 to 14, wherein R2 and R3 contain from 1 to 3 carbon atoms, and preferably 1 carbon atom, wherein n is an integer of from 1 to 10, preferably from 1 to 6 and more preferably is 1, Y is selected from the group consisting of carboxyl and sulfonyl radicals and wherein the sum of R1, R2 and R3 radicals is from about 14 to about 24 carbon atoms, or mixtures thereof.

• the weight ratios of amine oxide to betaine or sulphobetaine are an important feature of the invention. Hence, ratios outside the range below, such as those where the betaine or sulphobetaine surfactant is in higher proportion than the amine oxide, would not provide the cleaning and shine benefit but only the cleaning benefit while still leaving greasy residues. On the other hand, a ratio above 100:1 of amine oxide to betaine or sulphobetaine surfactant would result in a surface showing spotty residues of the crystalline type. Thus, it is an important feature that the amine oxide and betaine or sulphobetaine surfactant be present within the composition in a weight ratio of 1:1 to 100:1, preferably from 10:1 to 50:1, more preferably 15:1 to 30:1.
