Description

COMPOSITIONS STABLE LIQUID DETERGENTS QUF CQMPRENDFN FLASQ GRASQ AND PE SILICQN OIL FIELD OF TNVFNCION The present invention relates to stable homogeneous liquid detergent compositions. More particularly, the present invention relates to liquid detergent compositions comprising a foam suppression system, said foam suppression system comprising a silicone antifoaming agent and a mixture of specific fatty acids.

BACKGROUND OF THE INVENTION One of the pressing trends in current liquid detergent business is the shift to more concentrated liquid detergents. This change offers the inherent efficiency of manufacturing and use of liquid formulas, such as pumping capacity and easy measurement of liquids, while reducing the large amount of packaging and shipping costs. This trend is occurring both in products for sale to the consumer and in industrial formulations. The turn towards concentrated liquids generally links the reduction of water content in a formulated liquid. This results in an increase in electrolyte and solid levels in these liquid detergent formulas. Another change is the dependence on non-aqueous solvents to aid in the solubilization of detergent components such as co-surfactants. These two changes make it more difficult to stabilize certain detergent ingredients against physical separation and / or aggregation phenomena. One of these ingredients includes silicone antispurring agents. Said silicone anti-foaming agents are included in detergent compositions to control the amount of foam produced during a washing cycle in a washing machine. Agents to silicone bakers in finely dispersed form have been found to be a particularly effective species. However, it is particularly difficult to homogenously disperse antifoam formulations in concentrated liquid detergents. Therefore, an object of the present invention is to provide a foam suppression system that is capable of providing a foam controller profile for concentrated liquid detergents. Another object of this invention is to provide homogeneous liquid detergent compositions that remain stable, particularly under prolonged storage. The above objectives have been met by a foam suppression system comprising a silicone anti-foaming agent in combination with a specific mixture of fatty acids. It has surprisingly been found that the addition of a specific mixture of fatty acids provides a synergistic increase in the effectiveness of enzyme suppression of the silicone antispilling agent. This finding makes it possible to reduce the level of silicone anti-foaming agent while maintaining the control profile of detergent foams that contain silicone.

BRIEF DESCRIPTION PE Lfl INVENCIQQN The present invention relates to liquid detergents containing concentrated Nil-Lae comprising a silicone oil and a mixture of fatty acids, characterized in that said mixture of fatty acids comprises i) at least 20% more saturated fatty acid; n) at least 30% of fatty acid having 16 or more carbon atoms. All percentages, relationships herein are by weight, unless otherwise specified.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to concentrated liquid detergents, in which case, the liquid detergent compositions according to the present invention will contain a lower amount of water, compared to conventional liquid detergents. The water level in the concentrated liquid detergents of the present invention is less than 50%, preferably less than 40%, most preferably less than 30% water by weight of the total detergent compositions. The concentrated liquid detergents of the present invention comprise a silicone oil and a mixture of fatty acids, characterized in that said fatty acid mixture comprises i) at least 20% of unsaturated fatty acid, "ii) at least 30% of fatty acid having 16 or more carbon atoms.The mixtures of preferred fatty acids comprise at least minus 40% unsaturated fatty acid and at least 50% fatty acid having 16 or more carbon atoms Examples of fatty acids suitable for use in the fatty acid mixture of the present invention include palmitoleic acid, safflower, sunflower, soybean, oleic, linoleic, linolenic, ricinoleic, rapeseed oil or mixtures thereof The mixtures of saturated and unsaturated fatty acids can also be used herein Preferred mixtures include mixtures of palm tree seed fatty acid and fatty acid rape seed in a ratio of): 1 to 1: 9, preferably 3: 1 to 1: 9. Suitable sources of fatty acids are well known, for example, see Bailey, Industrial Oil and fat Products, tert. was edition, S ern, published by Interscience Publisher, 1964. It will be recognized that the fatty acid will be present in the detergent composition mainly in the form of a soap. Suitable cations include cations of sodium, potassium, ammonium, monoethanolammonium, diethanolammonium, triethanolamine, tetraalkylammonium, e.g., tetrarethylammonium to tetradecylammonium, etc. The amount of fatty acid will vary depending on the particular characteristics desired in the final detergent composition. For any detergent compositions that are to be used in automatic washing machines, the spray should not be formed to the extent that it spills from the washing machine. The foam suppressors, when used, are preferably present in a "foam suppressant amount". By "foam suppressing amount" is meant that the composition forulator may select an amount of this foaming controlling agent that will sufficiently control the foams to produce a low sputtering detergent for laundry, for use in automatic washing machines. Preferably, the weight ratio of the fatty acid to silicone mixture is from 1: 1 to 400: 1, most preferably from 10: 1 to 200: 1. It has been found that the specific fatty acids selected in accordance with the present invention synergistically increase the foam suppressor activity of silicone foams. The silicone / fatty acid combination according to the present invention gives a better statistically significant foam suppressing activity that is better than the sum of the individual foam suppressor activity of both ingredients. In industrial practice, the term "suppressor of 5 silicone foams" has become a generic term encompassing a variety of relatively high molecular weight polymers containing siloxane units and hydrocarbon groups of various types. Generally, silicone sub-controllers can be described as siloxanes. "A having the general formula: R wherein n is from 20 to 2,000, and wherein each R independently can be an alkyl or aryl radical. Examples of said substituents are methyl, ethyl, propyl, isobutyl and phenyl.

Other silicone foam suppressors are described in USPatent 3,455,839, which relates to compositions and methods for removing foams from aqueous solutions by incorporating in them small amounts of polydimethylsiloxane fluids. Mixtures of silicone and silanated silica are described, for example, in German Patent Application DOS 2,124,526. Silicone foam scavengers and foam controlling agents in granular detergent compositions are described in U.S. Patent 3,933,672 and U.S. Patent 4,652,392.
