1. Field of Invention
This invention relates to a light duty liquid cleaning composition which is mild to the skin and which demonstrates improved sensory attributes and foam when used as a hand soap designed in particular for dishware and which is effective in grease and is high foaming and clear.
2. Background of the Invention
The present invention relates to light duty liquid detergent compositions with high foaming properties, which contains mixtures of anionic surfactants, amine oxide surfactant, alkyl polyglucoside surfactant and an oxyethylene functional organosilane.
The prior art is replete with light duty liquid detergent compositions containing nonionic surfactants in combination with anionic and/or betaine surfactants wherein the nonionic detergent is not the major active surfactant, as shown in U.S. Pat. No. 3,658,985 wherein an anionic based shampoo contains a minor amount of a fatty acid alkanolamide. U.S. Pat. No. 3,769,398 discloses a betaine-based shampoo containing minor amounts of nonionic surfactants. This patent states that the low foaming properties of nonionic detergents renders its use in shampoo compositions non-preferred. U.S. Pat. No. 4,329,335 also discloses a shampoo containing a betaine surfactant as the major ingredient and minor amounts of a nonionic surfactant and of a fatty acid mono- or di-ethanolamide. U.S. Pat. No. 4,259,204 discloses a shampoo comprising 0.8-20% by weight of an anionic phosphoric acid ester and one additional surfactant which may be either anionic, amphoteric, or nonionic. U.S. Pat. No. 4,329,334 discloses an anionic-amphoteric based shampoo containing a major amount of anionic surfactant and lesser amounts of a betaine and nonionic surfactants.
U.S. Pat. No. 3,935,129 discloses a liquid cleaning composition based on the alkali metal silicate content and containing five basic ingredients, namely, urea, glycerin, triethanolamine, an anionic detergent and a nonionic detergent. The silicate content determines the amount of anionic and/or nonionic detergent in the liquid cleaning composition. However, the foaming property of these detergent compositions is not discussed therein.
U.S. Pat. No. 4,129,515 discloses a heavy duty liquid detergent for laundering fabrics comprising a mixture of substantially equal amounts of anionic and nonionic surfactants, alkanolamines and magnesium salts, and, optionally, zwitterionic surfactants as suds modifiers.
U.S. Pat. No. 4,224,195 discloses an aqueous detergent composition for laundering socks or stockings comprising a specific group of nonionic detergents, namely, an ethylene oxide of a secondary alcohol, a specific group of anionic detergents, namely, a sulfuric ester salt of an ethylene oxide adduct of a secondary alcohol, and an amphoteric surfactant which may be a betaine, wherein either the anionic or nonionic surfactant may be the major ingredient.
U.S. Pat. Nos. 5,326,557 and 5,435,996 disclose oxyethylene functional organic silanes for use in body care formulations.
It has now been found that a light duty liquid detergent can be formulated with a mixture of anionic surfactants, alkyl polyglucoside, alkyl monoalkanol amide, surfactant, silicone polymer and water which has desirable cleaning properties, mildness to the skin and improved foam qualities.
An object of this invention is to provide a light duty liquid detergent composition which comprises a sulfate surfactant, a sulfonate anionic surfactant, alkyl monoalkanol amide, an alkyl polyglucoside surfactant, an oxyethylene functional organosilane, solubilizing system and water wherein the composition does not contain an amine, enzyme, propanediol, or an aminopolyphosphate.
Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
