The powdery adjuvant composition comprises the oil-soluble agent (s), which powder composition is used in detergent bar compositions to enhance delivery of the oil-soluble agent. The carrier used to form the adjuvant should have a melting point high enough to withstand the spray drying process. Specifically, the present invention provides (A) (a) 1 to 70% by weight powder soluble agent; (b) 15 to 98 weight percent of powder carrier; (c) 1 to 10% by weight of powder water; And (d) from 0 to 30% by weight of a powder comprising (i) 0 to 30% by weight of a powder deposition / processing aid (eg, surfactant, cationic polymer and / or hydrophilic polymer); And (B) 5 to 90 weight percent of a chip comprising 5 to 90 weight percent of a surfactant system selected from the group consisting of soaps, anionic surfactants, nonionic surfactants, amphoteric surfactants, cationic surfactants, and mixtures thereof. It relates to a bar composition comprising%. The invention also mixes (a), (b), (c) and optional (d) at 40 to 80 ° C., and the mixture of (a) and (b) to a temperature of 80 to 200 ° C. and 0.10 to 0.30 Spray drying at a pressure of mPa to prepare (A) and (B) separately, mixing (P) and (B), preparing, and extruding to form a final bar. To provide. |
