Liquid fabric softening composition
The present disclosure provides compositions for use as in-rinse softeners for textiles. The compositions can be in the form of liquid fabric softeners that can be configured to substantially avoid build-up on treated fabrics. In particular, the compositions can comprise predominately water and at least a conditioning agent, such as a polymeric quaternary ammonium salt, that will provide conditioning and softening effects to a treated fabric without leaving behind undesired build-up. The compositions optionally may include further components, such as anti-static agents, chlorine scavengers, preservatives, and acidifying agents.
1. An in-rinse liquid fabric softening composition comprising:
a polymeric quaternary ammonium salt effective as a conditioning agent in an amount of about 0.4% to about 1.2% by weight based on the total weight of the composition, the polymeric quaternary ammonium salt being a polyquaternium material;
water in an amount of 96% to 99.5% by weight based on the total weight of the composition; and
an anti-static agent in an amount of about 0.6% to about 3% by weight based on the total weight of the composition, the anti-static agent including at least a non-polymeric quaternary ammonium salt;
wherein the composition excludes ester quaternary compounds.
2. The in-rinse liquid fabric softening composition of claim 1 , wherein the at least non-polymeric quaternary ammonium salt is laurtrimonium chloride.
3. The in-rinse liquid fabric softening composition of claim 1 , further comprising a chlorine scavenger.
4. The in-rinse liquid fabric softening composition of claim 3 , wherein the chlorine scavenger is a polyethyleneimine.
5. The in-rinse liquid fabric softening composition of claim 3 , wherein the chlorine scavenger is present in an amount of about 0.1% to about 0.3% by weight based on the total weight of the composition.
6. The in-rinse liquid fabric softening composition of claim 1 , further comprising an acidifying agent.
7. The in-rinse liquid fabric softening composition of claim 6 , wherein the acidifying agent is present in an amount of about 0.1% to about 0.8% by weight based on the total weight of the composition.
8. The in-rinse liquid fabric softening composition of claim 1 , further comprising one or more preservatives.
9. The in-rinse liquid fabric softening composition of claim 8 , wherein the one or more preservatives are present in a total amount of about 0.003% to about 0.008% by weight based on the total weight of the composition.
10. The in-rinse liquid fabric softening composition of claim 1 , wherein the composition excludes conditioning agents that are not polymeric quaternary ammonium salts.
11. The in-rinse liquid fabric softening composition of claim 1 , wherein the conditioning agent is polyquaternium-37.
12. An in-rinse liquid fabric softening composition consisting essentially of:
one or more polymeric quaternary ammonium salt conditioning agents in an amount of about 0.4% to about 1.2% by weight based on the total weight of the composition, the one or more polymeric quaternary ammonium salt conditioning agents being one or more polyquaternium materials;
one or more acidifying agents;
one or more preservatives;
an anti-static agent in an amount of about 0.6% to about 3% by weight based on the total weight of the composition, the anti-static agent including at least a non-polymeric quaternary ammonium salt;
optionally one or more scents; and
water in an amount of 96% to 99.5% by weight based on the total weight of the composition;
wherein the composition excludes ester quaternary compounds.
13. An in-rinse liquid fabric softening composition consisting of:
one or more polymeric quaternary ammonium salts effective as a conditioning agent in an amount of about 0.1% to about 1.5% by weight based on the total weight of the composition; and
water in an amount of about 96% to 99.5% by weight based on the total weight of the composition;
wherein the composition excludes ester quaternary compounds.
14. The in-rinse liquid fabric softening composition according to claim 13 , further comprising one or more components selected from the group consisting of chloring scavengers, acidifying agents, preservatives, and scents.
