- 3. The mild soap bar composition of claim 1 wherein said soap comprises fatty acid soaps having fatty acid carbon chain lengths of C.sub.8 -C.sub.22.
- 4. The mild soap bar composition of claim 1 wherein said bar contains at least 25% tallow soap.
- 5. The mild soap bar composition of claim 1 wherein said soap is a mixture of tallow and coconut soaps having a ratio of 0.1:1 to 9:1.
- 6. The mild soap bar composition of claim 5 wherein said ratio is 1:1 to 1.5:1.
- 7. The mild soap bar composition of claim 1 wherein said composition contains from about 2% to about 20% of a synthetic surfactant selected from alkyl glyceryl ether sulfonates, anionic acyl sarcosinates, methyl acyl taurates, N-acyl glutamates, alkyl glucosides, acyl isethionates, alkyl sulfosuccinates, alkyl phosphate esters, ethoxylated alkyl phosphate esters, methyl glucose esters, protein condensates, mixtures of ethoxylated alkyl sulfates and alkyl amine oxides, betaines, sultaines, the alkyl ether sulfates with 1 to 12 ethoxy groups, and mixtures thereof, wherein said synthetic surfactants contain C.sub.8 -C.sub.22 alkyl chains.
- 8. The mild soap bar composition of claim 7 wherein said synthetic surfactant has an alkyl chain length of C.sub.10 -C.sub.18.
- 9. The mild soap bar composition of claim 1 wherein said composition contains up to 20% of a C.sub.10 -C.sub.18 alkyl glyceryl ether sulfonate.
- 10. The mild soap bar composition of claim 1 wherein said composition contains from about 2% to about 17% moisturizer.
- 11. The mild soap bar composition of claim 1 wherein the other cationic polysaccharide polymer is cationic hydroxyethylcellulose polymer.
- 12. A method of making a mild soap bar in accordance with claim 1 comprising the steps of:
- (1) hydrating an effective amount of said cationic guar gum polymer with water, and
- (2) uniformly distributing and incorporating the hydrated cationic guar gum polymer into an aqueous soap mix whereby said hydrated cationic guar gum polymer is substantially uniformly distributed and incorporated in said aqueous soap mix, and
- (3) drying said uniform mix to a moisture level of from 7% to 25%, and
- (4) forming the dried product obtained by step (3) into a bar shape.
- 13. The method of making a mild soap bar in accordance with claim 12 wherein said cationic polymer is hydrated in a soap making crutcher step.
- 14. The method of claim 12 wherein said polymer is hydrated with water prior to mixing with said aqueous soap mix.
- 15. The method of claim 12 wherein said hydrated polymer is a free flowing liquid and is injected into a liquid soap stream prior to drying.
- 16. The method of claim 12 wherein said hydrated polymer is a cationic guar gum gel which is mixed in a soap crutcher step mixture containing 25% to 40% water.
- 17. The method of claim 12 wherein said bar has a moisture level of 7% to 15%.
