Antiperspirant composition
An antiperspirant composition including a starch delivery vehicle which includes a starch, a core material, and a lipophilic phosphate ester, wherein the lipophilic phosphate ester at least partially coats the core material.
1. An antiperspirant composition comprising an antiperspirant active, and a starch perfume delivery vehicle comprising an octenylsuccinic acid anhydride modified starch, a perfume, and an octyl phosphate ester, wherein the octyl phosphate ester at least partially coats the perfume and is a reaction product of the octyl phosphate ester and a multivalent ion, and wherein the perfume is miscible in the octyl phosphate ester.
2. The antiperspirant composition of claim 1 , wherein the antiperspirant composition is anhydrous.
3. The antiperspirant composition of claim 1 , wherein the octyl phosphate ester has an acid value below about 950 mg KOH/g phosphate ester.
4. The antiperspirant composition of claim 1 , wherein the octyl phosphate ester has an acid value of about 180 mg KOH/g phosphate ester to about 450 mg KOH/g phosphate ester.
5. The antiperspirant composition of claim 1 , wherein the perfume and octyl phosphate ester form a lipophilic phase in which the perfume forms from about 60% to about 90% of the lipophilic phase.
6. The antiperspirant composition of claim 1 , wherein the multivalent ion is selected from the group consisting of calcium chloride, aluminum sulfate, chitosan, polyethyleneimine (“PEI”) and polydiallyldimethylammonium chloride (“polyDADMAC”).
7. The antiperspirant composition of claim 1 , wherein the perfume has a ClogP value of about 1 to about 5.
8. The antiperspirant composition of claim 1 , wherein the perfume has a ClogP value of about 3 to about 4.5.
9. The antiperspirant composition of claim 1 , wherein the antiperspirant active comprises aluminum.
