- 1.00% by weight of fragrance.
- 10. A method of making a clear solid topical deodorant composition of claim 1 comprising:
- forming a liquid phase comprising at least one water-insoluble ester of a water-soluble acid having solubility in water of less than 50% w/w at 20.degree. C., said liquid phase being substantially free of water and of water-miscible solvents which are liquid at ambient temperature, and any optional ingredients;
- heating said liquid phase to 100.degree. C.;
