Abstract:
An anhydrous antiperspirant or deodorant composition having a conductance of at least 250 micro Siemens at a loading of at least 7% by weight of an antiperspirant as measured by a fixed geometry test, wherein the composition is an emulsion comprising:(I) an external phase comprising: (a) 0.1-25% of an organic naphthalate ester having a refractive index in the range of 1.43-1.60 which is not soluble in alcohol or glycols in an amount greater than 1.0%; (b) a sufficient amount of a silicone copolyol to achieve a solids content of 0.25-10%, wherein the silicone copolyol may be added with or without solvent; (c) a sufficient amount of a volatile silicone to achieve a total amount of the external phase as 15-33%; and (d) 0-5% of a silicone elastomer; and (II) an internal phase comprising: (a) 0.1-30% of an antiperspirant active (on an anhydrous basis); and (b) a sufficient amount of a glycol component to dissolve the antiperspirant active and to complete the internal phase up to a maximum of 80% glycol component; wherein the ratio of the external phase to the internal phase is in the range of 1:1-1:4 and all amounts are in percent by weight based on the total weight of the composition.
