wherein said composition comprises from about 0.1 to about 3% of said one or more fragrance oils by weight of the composition and from about 1 to about 20% of said one or more triglyceride oils by weight of the composition,
wherein said composition is in the form of an oil-in-water emulsion; and
wherein said composition is a liquid having a viscosity below 7000 cps at 25° C.
2. The antiperspirant composition of claim 1 , wherein said triglyceride oils collectively have a saturated fatty acid content of at least 85%.
3. The antiperspirant composition of claim 1 , wherein said triglyceride oils collectively have a saturated fatty acid content of at least 90%.
4. The antiperspirant composition of claim 1 , wherein the fatty acid content of said triglyceride oils comprises at least 75% fatty acids having a chain length of C16 or less.
5. The antiperspirant composition of claim 1 , wherein said one or more triglyceride oils comprise coconut oil.
6. The antiperspirant composition of claim 1 , wherein said oil phase comprises less than 5% of a triglyceride oil selected from the group consisting of sunflower seed oil, rapeseed oil, corn oil, cottonseed oil, flaxseed oil, olive oil, safflower oil, soybean oil, canola oil, peanut oil, sesame oil, almond oil, castor oil, and combinations thereof.
7. The antiperspirant composition of claim 1 , wherein said one or more antiperspirant actives is selected from the group consisting of an aluminum salt, an aluminum/zirconium salt, an aluminum glycol complex, an aluminum/zirconium glycol complex, or combinations thereof.
8. The antiperspirant composition of claim 1 , further comprising a polyol.
9. The antiperspirant composition of claim 8 , wherein said polyol comprises glycerol.
10. The antiperspirant composition of claim 1 comprising:
(a) from about 0.1 to about 3% of one or more fragrance oils;
(b) from about 1 to about 20% coconut oil;
(c) from about 5 to about 25% of an aluminum-based or aluminum/zirconium-based antiperspirant active;
(d) from about 2 to about 20% polyol;
(e) from about 50 to about 90% water; and
(f) from about 1 to about 7% of one or more emulsifiers.
11. The antiperspirant composition of claim 10 wherein said one or more emulsifiers collectively have an HLB value of between 6-12.
12. The antiperspirant composition of claim 1 , further comprising one or more antioxidants.
13. The antiperspirant composition of claim 1 , wherein said one or more antioxidants comprise a water-insoluble sterically hindered phenolic antioxidant.
14. The antiperspirant composition of claim 1 , wherein the composition contains one or more hair minimizing actives.
15. The antiperspirant composition of claim 1 , wherein the composition contains one or more skin lightening agents.
16. The antiperspirant composition of claim 12 , wherein the total amount of said one or more antioxidants is ≤0.20% by weight of the composition.
17. The antiperspirant composition of claim 1 , wherein the composition comprises from about 2 to about 20% polyol by weight of the composition and from about 50 to about 90% water by weight of the composition.
