Abstract:
A low water emulsion made by combining 15-33% of an external phase and 67-85% of an internal phase wherein:(I) the external phase comprises: (a) 1-25% of an organic ester having a refractive index in the range of 1.43-1.60 and which allows the release of an antiperspirant active; (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 quantum sufficient amount of the external phase as 15-33%; (d) 0-5% of a silicone elastomer (on an actives basis); and (e) 0-15% of at least one emollient. (II) the internal phase comprises: (a) an effective amount of at least one cosmetically active ingredient selected from the group consisting of 0.1-25% of an antiperspirant active (on an anhydrous basis), 0.1-3% of a fragrance, and 0.05-5% of an antimicrobial; (b) a sufficient amount of a solvent component to dissolve the cosmetically active ingredient and to complete the internal phase up to a maximum of 80% of solvent; (c) 0.5-15% of water optionally containing up to 30% of an ionizable salt soluble in water; (d) 0-5% of a non-ionic emulsifier; and (e) 0-10% ethanol; wherein: the final refractive index of the composition is in the range of 1.42-1.52; and all amounts are in percent by weight based on the entire weight of the composition.
