Abstract
Builder-free highly concentrated homogeneous fatty acid containing liquid detergent compositions are disclosed. The surface-active system in addition to the fatty acids also contains substantial amounts of anionic sulfonate/sulfate detergents and nonionic ethoxylates. The compositions are mildly acid to neutral and are capable of providing unexpectedly superior textile cleaning benefits, especially on oily and bleach sensitive soils.
Claims12
A highly concentrated homogeneous liquid detergent composition comprising
- (a) from about 35% to about 75% by weight of a ternary active system consisting essentially of:
- (i) anionic synthetic surface-active salt selected from the group consisting of sulfonates and sulfates having an alkyl radical containing from about 8 to about 22 carbon atoms and wherein the neutralizing cation is selected from the group consisting of sodium, potassium, lithium, amines and substituted amines;
- (ii) ethoxylated nonionic surface-active agent derived from alcohols having from 8 to 24 carbon atoms and having from 2 to about 14 moles of ethylene oxide per mole of hydrophobic moiety;
- (iii) from about 8% to about 20% by weight of the composition of fatty acid having from about 10 to 18 carbon atoms;
- (b) phase regulant which is selected from the group consisting of lower aliphatic alcohols having from 2 to 6 carbon atoms and 1 to 3 hydroxyl groups, esters of diethylene glycol and lower aliphatic monoalcohols having from 1 to 4 carbon atoms, and detergent hydrotropes;
- and water;
- wherein the weight ratio of (i) to (ii) is in the range from about 10:1 to 2:1, and the total amount (weight %) of (i)+(ii) is greater than the total amount (weight %) of (iii), said composition having a pH at 20.degree. C. in the range of from 6.0 to 7.5.
