Claims
- 1. A liquid surfactant composition mobile at a temperature within the range of 20.degree. to 80.degree. C. consisting of:
- (a) a sodium or potassium salt of an alkylbenzene sulphonate or alkyl sulphate in an amount of about 20% to 70% by weight,
- (b) an ethoxylated nonionic surfactant in an amount of about 20% to 80% by weight; and
- (c) water in an amount sufficient to result in said composition being mobile but not exceeding 20% by weight; characterized in that said composition further consists of
- (d) 0.5 to 80% by weight of a fatty acid having 8 to 22 carbon atoms.
- 2. A composition according to claim 1, comprising 2 to 15% by weight of the fatty acid.
- 3. A composition according to claim 1, comprising 2 to 7% by weight of the fatty acid.
- 4. A composition according to claim 1, wherein the fatty acid is a C16-C18 fatty acid.
- 5. Process for preparing a liquid surfactant composition according to claim 1 comprising:
- mixing said nonionic surfactant with a concentrated aqueous alkali metal hydroxide solution having about 80% to 98% of the stoichiometric amount of said alkali metal hydroxide necessary to neutralize an acid precursor of said sulphate or sulphonate, to form a nonionic alkali dispersion;
- mixing said acid precursor with said dispersion to form a blend;
- adjusting the pH to about 7;
- mixing said blend with said fatty acid to form said mobile composition.
- 6. Process for the continuous manufacture of a particulate detergent composition having bulk density of at least about 500 g/l, which comprises contacting a liquid surfactant composition according to claim 1 with a solid particulate material at a temperature within the range of 20.degree. to 80.degree. C.
- 7. Process according to claim 5, wherein the solid particulate material is a spray-dried powder.
- 8. Process according to claim 6, wherein the solid particulate material comprises zeolite.
