Low water emulsions are described which are useful for antiperspirants and/or deodorants wherein the emulsions are made by combining (I) 15-33% of an external phase comprising: (a) 1-25% of an organic ester having a refractive index in the range of 1.43-1.60 and capable of releasing an antiperspirant active to achieve a specified conductivity; (b) a sufficient amount of a silicone copolyol to achieve a solids content of 0.25-10%; (c) a sufficient amount of a volatile silicone to achieve a total amount of the external phase as 15-33%; (c) 0-5% of a silicone elastomer (on an actives basis); and (d) 0-15% of at least one emollient; and (II) 67-85% of an internal phase comprising: (a) an effective amount of at least one cosmetically active ingredient; (b) a sufficient amount of a solvent component to dissolve the cosmetically active ingredient with a maximum amount being about 80%; (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: (1) the final refractive index of the composition is in the range of 1.42-1.52; and (2) the conductance of the composition is at least 250 micro Siemens/cm/ml at a loading of at least 7% by weight level of antiperspirant active.

Stable emulsions for cosmetic products

This invention comprises a one-phase cosmetic composition which can be made as a stick, gel or cream and which has low residue, low tack and improved fragrance substantivity. The cosmetic compositions are formed by (a) from 0.5-50 weight percent of a dimethicone copolyol ester compound soluble in propylene glycol; (b) from 50-98 weight percent of a gellant/solvent system which comprises a mixture of; (i) 0.5-4.0 weight percent dibenzylidene sorbitol; (ii) 0.05-1.0 weight percent of a co-gellant or structural integrity enhancer; (iii) 0.1-80 weight percent of a polyhydric alcohol solvent; (c) 0.5-10% of a small particle size zinc oxide having a particle size in the range of 20 nanometers-200 microns; and (d) 0.1-3.0% fragrance.
