Description

Clear Fabric Conditioner Composition
Technical Field
This invention relates to clear or translucent fabric conditioner composition. The composition of the present invention has reduced amount of non-aqueous solvent.
Background and Prior Art
Fabric conditioners are well known in the art. Fabric conditioners that are clear or translucent have a better visual appeal and are being increasingly preferred by consumers. Consequently, various approaches have been used in the prior art to produce clear or translucent fabric conditioners .
GB2211510 (Colgate-Palmolive Company, 1989) teaches fabric conditioning and antistatic detergent compositions or softergents which include 10-35% by weight a narrow range ethoxylate nonionic detergent, 2- 15% by weight a fabric conditioning and antistatic cationic compound such as Ci2-Ci8 quaternary ammonium halide and 30-70% by weight water. The compositions of this prior art invention are superior in detersive action compared to identical compositions except for replacement of the narrow range ethoxylate with a broad range ethoxylate nonionic detergent . The superior detersive action is attributed to the presence of the narrow range ethoxylated nonionic detergent that are believed to counteract the negative effect of quaternary ammonium halide on detergency. This invention of is directed at improving detergency of fabric conditioner compositions .
US005399272 (Procter & Gamble Company, 1995) teaches fabric conditioning compositions comprising 20-80% by weight of fabric conditioner active, 2-25% C8-C22 monoalkyl cationic quaternary ammonium compound dispersibility aid and 17-75% non-aqueous solvent, wherein the fatty acyl components of the fabric conditioner active have an average Iodine Value of at least 50. The use of C8-C22 quaternary ammonium compounds has been taught as an auxiliary ingredient to the fabric conditioner active as a dispersibility aid.
EP1149891 (Goldschmidt Chemical Company, 2001) teaches aqueous laundry detergent compositions comprising a blend of quaternary ammonium fabric conditioner actives 1-50% by weight of at least one anionic scavenger and 50-99% by weight of at least on triglyceride based ester quat . The use of C8-C22 quaternary ammonium compounds has been taught as an auxiliary ingredient to the fabric conditioner active as an anionic scavenger.
One of the difficulties in formulating clear or translucent fabric conditioner composition is that incorporation of fragrance, typically containing a large fraction of hydrophobic water-insoluble compounds, causes turbidity. Attempts to formulate clear or translucent fabric conditioner composition comprising fragrance have necessitated use of expensive fabric conditioner actives that have higher solubility as compared to conventional conditioner actives and/or the use of non-aqueous solvents at a high level in the formulation that may not be desirable from environmental and safety points of view. Thus there is a clear and distinct need to develop clear or translucent fabric conditioner composition that comprises less expensive fabric conditioner actives and yet contains lower amounts of non-aqueous solvents.
Therefore one of the objects of the present invention is to devise clear or translucent fabric conditioner composition comprising fragrance which is based on less expensive fabric conditioner actives .
Another object of the present invention is to devise clear or translucent fabric conditioner composition that has reduced level of non-aqueous solvents, preferably below 10% by weight.
It has been now surprisingly found that it is possible to devise clear or translucent fabric conditioner compositions comprising fragrance which are based on less expensive fabric conditioner actives and reduced amount of non-aqueous solvents.
Summary of the Invention According to the present invention there is provided a clear or translucent fabric conditioner composition comprising
0.1-30% by weight a quaternary ammonium fabric conditioner active of the formula RR1R2R3N+X", where, R is an alkyl group with 16 to 22 carbon atoms, R1, R2 and R3 are alkyl groups with 1 to 4 carbon atoms, X is a an anion selected from chloride, bromide, acetate, sulfate, nitrate, and phosphate;
0.1-15 % by weight a hydrotrope selected from fatty alcohol ethoxylates and alkylene polyols or mixtures thereof;
0.001-10% by weight fragrance; and
45-99 % by weight water;
wherein nonaqueous solvents including short chain C1-C6 alcohols, Ci-C4 alkylene carbonates and short chain C2-C8 alkyl ethers are at levels not greater than 10% by weight of the composition.
