Claims
- 1. A process for the preparation of a fatty acid salt product which comprises (1) forming a reactive admixture of ingredients comprising (a) C.sub.14 -C.sub.22 fatty acid having about 2-40 weight percent of the C.sub.14 -C.sub.22 fatty acid content in glyceride form, (b) basic alkali metal or ammonium compound, and (c) aqueous medium, and conducting the reaction for a period sufficient to hydrolyze the gylceride constituent to C.sub.14 -C.sub.22 fatty acid and glycerol, and to form an aqueous dispersion of C.sub.4 -C.sub.22 fatty acid salt; (2) forming a reactive admixture of ingredients comprising (a) C.sub.14 -C.sub.22 fatty acid salt aqueous dispersion from step (1), and (b) between about 0.8-1.4 equivalents of water-soluble alkaline earth metal compound per equivalent of C.sub.4 -C.sub.22 fatty acid salt; and (3) recovering C.sub.4 -C.sub.22 fatty acid alkaline earth metal salt product after completion of a salt-forming reaction in step (2), wherein the salt product has a content of free C.sub. 14 -C.sub.22 fatty acid or C.sub.4 -C.sub.22 fatty acid glyceride respectively less than about one weight percent, based on the weight of C.sub.14 -C.sub.22 fatty acid content.
- 2. A process in accordance with claim 1 wherein the C.sub.4 -C.sub.22 fatty acid ingredient, in step (1) comprises at least two C.sub.4 -C.sub.22 fatty acid constituents.
- 3. A process in accordance with claim 1 wherein the fatty acid ingredient in step (1) is a mixture comprising 0-10 percent lauric acid, 0-60 percent palmitic acid, 0-15 percent stearic acid, 0-60 percent oleic acid, and 0-20 percent linoleic acid, in the form of free fatty acids and fatty acid glycerides.
- 4. A process in accordance with claim 1 wherein the quantity of alkali metal or ammonium compound ingredient in step (1) is at least one equivalent per equivalent of C.sub.14 -C.sub.22 fatty acid and C.sub.14 -C.sub.22 fatty acid glyceride.
- 5. A process in accordance with claim 1 wherein the alkali metal or ammonium compound ingredient is step (1) is a water-soluble sodium, potassium or ammonium compound or any mixture thereof selected from bicarbonates, carbonates, phosphates and hydroxides.
- 6. A process in accordance with claim 1 wherein the reaction period in step (1) is about 0.1-1.5 hours, and the reaction temperature is about 30.degree.-110.degree. C.
- 7. A process in accordance with claim 1 wherein the quantity of C.sub.14 -C.sub.22 fatty acid salt derivative formed in step (1) comprises about 20-70 weight percent, based on the weight of aqueous dispersion.
- 8. A process in accordance with claim 1 wherein the pH of the aqueous dispersion in step (1) is in the range of about 7-10.5.
- 9. A process in accordance with claim 1 wherein the alkaline earth metal compound in step (2) is selected from calcium chloride, calcium nitrate, magnesium chloride, magnesium sulfate and magnesium nitrate.
- 10. A process in accordance with claim 1 wherein the salt-forming reaction temperature in step (2) is about 30.degree.-110.degree. C., and the reaction period is about 0.3-2 hours.
- 11. A process in accordance with claim 1 wherein water evaporation occurs during the salt-forming reaction in step (2) and the salt product is recovered in the form of friable granules.
- 12. A process in accordance with claim 1 wherein a biologically active constituent is incorporated as an additional ingredient during the processing.
