Solid fabric conditioner composition and method of use
The present invention relates to a composition and method for treating a textile under industrial and institutional fabric care conditions to impart softness with reduced yellowing. More particularly, the present invention relates to a solid fabric conditioning composition and a method for treating a textile with a solid fabric conditioning composition.
1. A solid fabric softening composition comprising:
(a) from about 5 wt. % to about 10 wt. % of one or more surfactants;
(b) from about 5 wt. % to about 20 wt. % of a polyethylene glycol with a molecular weight of 4000 (PEG-4000) or 8000 (PEG-8000) and about 19 wt. % to about 30 wt. % of urea as solidification agents; and
(c) from about 30 wt. % to about 45 wt. % of a quaternary ammonium component and about 5 wt. % to about 10 wt. % of an amino-functional silicone compound,
wherein the surfactants are a C 10 -C 16 alcohol ethoxylate or mixtures thereof;
wherein the ester quaternary ammonium component is methyl bis[ethyl (tallowate)]-2-hydroxyethyl ammonium; and
wherein a ratio of the ester quaternary ammonium component to amino-functional silicone compound is between about 3:1 to about 9:1.
2. The composition of claim 1 , wherein the composition comprises about 5 wt. % to about 20 wt. % of a polyethylene glycol with a molecular weight of 4000 (PEG-4000).
3. The composition of claim 1 wherein the composition further comprises an additional softening agent comprising at least one of amidoamine quaternary ammonium, dimethyl ditallowamine, imidazoline quaternary amine and mixtures thereof.
4. The composition of claim 1 , wherein the solid composition is in the form of a block.
5. The composition of claim 1 wherein pH of the composition is in the range of about 2 to about 8.
6. A method of softening fabrics, comprising:
(a) washing the fabrics in a detergent with a pH range of about 7 to about 14;
(b) contacting the fabrics with a use solution of the composition of claim 1 , wherein the pH of the composition is in the range of about 2 to about 8; and,
(c) drying the fabrics.
7. A method of softening fabrics, comprising:
(a) washing the fabrics in a detergent with a pH range of about 7 to about 14;
(b) contacting the fabrics in a wash cycle or final rinse with a use solution of a composition, wherein the composition comprises:
i. from about 5 wt. % to about 10 wt. % of one or more surfactants;
ii. from about 5 wt. % to about 20 wt. % of a polyethylene glycol with a molecular weight of 4000 (PEG-4000) or 8000 (PEG-8000) and about 19 wt. % to about 30 wt. % of urea as solidification agents;
ii. from about 30 wt. % to about 45 wt. % of a quaternary ammonium component and about 5 wt. % to about 10 wt. % of an amino-functional silicone compound;
iv. the pH of the composition is in the range of about 2 to about 8; and
(c) drying the fabrics,
wherein the surfactants are a C 10 -C 16 alcohol ethoxylate or mixtures thereof;
wherein the ester quaternary ammonium component is methyl bis[ethyl (tallowate)]-2-hydroxyethyl ammonium; and
wherein a ratio of the ester quaternary ammonium component to amino-functional silicone compound is between about 3:1 to about 9:1.
8. The method of claim 7 wherein the composition comprises about 5 wt. % to about 20 wt. % of a polyethylene glycol with a molecular weight of 4000 (PEG-4000).
9. The method of claim 7 wherein the composition further comprises an additional softening agent comprising at least one of amidoamine quaternary ammonium, dimethyl ditallowamine, imidazoline quaternary amine and mixtures thereof.
10. The method of claim 7 wherein the solid is in the form of a block.
