Claims
- 1. In a liquid laundry detergent free from silicones containing amino substituents having fabric softening properties the improvement comprising a silicone fabric softening agent which is a hydrophobic cationic emulsion of a silicone polymer having a general formula: ##STR8## wherein: Me is methyl
- x and z have values of 3 to 100,000;
- y has a value of 1 to 10,000;
- R is (CH.sub.2).sub.n Z; Z is hydrogen;
- R" is a hydrogen or ##STR9## n has a value of 1 to 10.
- 2. The detergent in accordance with claim 1 including a carrier fluid selected from the group consisting of water, ethanol, isopropanol, butanol, hexanol, propylene glycol, and diethylene glycol.
- 3. The detergent in accordance with claim 1 in which the detergent includes at least one surfactant selected from the group consisting of anionic, nonionic, and cationic surfactants.
- 4. The detergent in accordance with claim 3 in which the ratio between the anionic surfactant and the nonionic surfactant is from about one to one to from about three to one.
- 5. The detergent in accordance with claim 3 in which the detergent includes on a weight basis about 0.5 to 5.0 percent of the silicone fabric softening agent.
- 6. The detergent in accordance with claim 5 in which the detergent is employed in an amount of about 0.05-0.3 percent by weight based on the weight of fabrics being treated.
- 7. In a method of treating fabrics in the wash cycle of a laundering process employing a detergent free from silicones containing amino substituents having through-the-wash softening benefits the improvement comprising utilizing as the silicone ingredient a silicone fabric softening agent selected from the group consisting of (i) a polydiorganosiloxane gum having an average unit formula ##EQU4## wherein each R is a monovalent radical selected from the group consisting of a methyl radical, a vinyl radical, a phenyl radical, an ethyl radical and a 3,3,3-trifluoropropyl radical, and a has an average value of 1.95 to 2.005 inclusive, at least 90 percent of the total R groups being methyl radicals, and molecules of said polydiorganosiloxane gum being terminated by a group selected from the group consisting of silanols, alkoxys and R.sub.3 SiO.sub.0.5 where R is defined above; (ii) a mixture of at least one volatile cyclic silicone and a polydiorganosiloxane gum as defined above; (iii) a mixture of a gum as defined above and a low viscosity polydiorganosiloxane; and (iv) a hydrophobic cationic emulsion of a silicone polymer having the formula ##STR10## wherein Me is methyl;
- x and z have values of 3 to 100,000;
- y has a value of 1 to 10,000;
- R is (CH.sub.2).sub.n Z; Z is hydrogen;
- R" is hydrogen or ##STR11## and n has a value of 1 to 10.
