Abstract
Water-dispersible solid compositions that comprise at least one water-soluble polysaccharide, and at least one quaternary ammonium compound, amine, or protonated amine compound as an active ingredient that is absorbed by the polysaccharide are disclosed. The compositions are useful for a wide variety of applications, such as fabric softener compositions, hair care compositions, sanitizing compositions, and well bore treatment compositions.
Claims20
A water-dispersible solid composition comprising:
- (a) from about 5% to about 70% by weight of at least one quaternary ammonium compound, amine or protonated amine, or mixtures thereof;
- wherein the quaternary ammonium compound is selected from (i) an esterquat that is the quaternized reaction product of a fatty acid source having an Iodine Value of 40 to 130 reacted with triethanolamine (TEA) at a fatty acid to alkanolamine molar ratio of 1.3:1 to 1.8:1, or reacted with methyl diethanolamine (MDEA) at a fatty acid to alkanolamine molar ratio of 1.0:1 to 2.0:1, (ii) an amidoamine quat, or (iii) a quaternary ammonium compound having the following chemical formula:
- where R1 is a straight or branched, saturated or unsaturated, alkyl or alkene chain having from 6 to 22, preferably from 8 to 18 carbon atoms;
- R2 is a straight or branched, saturated or unsaturated, alkyl or alkene chain having from 1 to 16 carbon atoms, preferably from 1 to 10 carbon atoms;
- R3 is methyl, ethyl, benzyl, or ethylbenzyl;
- R4 is methyl or ethyl;
- and
- X− is:
- Cl−, Br−, F−, I−, (SO42−)1/2, CH3OSO3−, HCO3−, (CO32−)1/2, or CH3COO−;
- and wherein the amine or protonated amine is selected from an esteramine, an amidoamine, or an amidoamine salt;
- (b) from about 30% to about 95% by weight of water-soluble polysaccharide having an aerated bulk density in the range of 100 g/L to 600 g/L, wherein the water-soluble polysaccharide comprises maltodextrin or agglomerated maltodextrin;
- and
- (c) optionally, up to 30% by weight of a solubilizer;
- wherein,
- the quaternary ammonium compound, amine or protonated amine has at least one alkyl chain of 10 carbons or greater, and is absorbed by the polysaccharide;
- with the proviso that, when the water-soluble polysaccharide is not agglomerated, the amount of the quaternary ammonium compound, amine, or protonated amine in the solid composition is not greater than 20% by weight, and when the water-soluble polysaccharide is agglomerated and has an aerated bulk density in the range of 250 g/L to 600 g/L, the amount of the quaternary ammonium compound, amine, or protonated amine in the solid composition is not greater than 35% by weight.
A method of making a water-dispersible solid composition comprising the steps of:
- providing a water-soluble polysaccharide in an amount of about 30% to about 95% by weight, based on the total weight of the solid composition, wherein the water-soluble polysaccharide comprises maltodextrin or agglomerated maltodextrin;
- adding from about 5% to about 70% by weight of at least one liquid or molten amine, protonated amine, or quaternary ammonium compound, or mixtures thereof, to the water-soluble polysaccharide, wherein the quaternary ammonium compound is selected from (i) an esterquat that is the quaternized reaction product of a fatty acid source having an Iodine Value of 40 to 130 reacted with triethanolamine (TEA) at a fatty acid to alkanolamine molar ratio of 1.3:1 to 1.8:1, or reacted with methyl diethanolamine (MDEA) at a fatty acid to alkanolamine molar ratio of 1.0:1 to 2.0:1, (ii) an amidoamine quat, or (iii) a quaternary ammonium compound having the following chemical formula:
- where R1 is a straight or branched, saturated or unsaturated, alkyl or alkene chain having from 6 to 22, preferably from 8 to 18 carbon atoms;
- R2 is a straight or branched, saturated or unsaturated, alkyl or alkene chain having from 1 to 16 carbon atoms, preferably from 1 to 10 carbon atoms;
- R3 is methyl, ethyl, benzyl, or ethylbenzyl;
- R4 is methyl or ethyl;
- and
- X− is:
- Cl−, Br−, F−, I−, (SO42−)1/2, CH3OSO3−, HCO3−, (CO32−)1/2, or CH3COO−;
- and wherein the amine or protonated amine is selected from an esteramine, an amidoamine, or an amidoamine salt;
- with the proviso that, when the water-soluble polysaccharide is not agglomerated, the amount of the amine, protonated amine, or quaternary ammonium compound added to the water-soluble polysaccharide is not greater than 20% by weight of the solid composition, and when the water-soluble polysaccharide is agglomerated, and has an aerated bulk density in the range of 250 g/L to 600 g/L, the amount of the amine, protonated amine, or quaternary ammonium compound added to the agglomerated polysaccharide is not greater than 35% by weight of the solid composition;
- and
- mixing the water-soluble polysaccharide and the amine, protonated amine or quaternary ammonium compound until the amine, protonated amine or quaternary ammonium compound is absorbed by the water-soluble polysaccharide to form the water-dispersible solid composition.
