The invention is a clear, elastomer-free, gel composition comprising: (a) 14&#x2013;30 weight % of an antiperspirant active having a low metal to chloride ratio; (b) 7&#x2013;23.3 weight % of one or more cyclomethicones having a flash point of 100 degrees C. or less; (c) 0.6&#x2013;0.9 weight % of a silicone surfactant having an HLB value&#x2266;8; (d) 30&#x2013;70 weight % water; (e) 3.85&#x2013;10 weight % of a water soluble glycol or polyglycol and (f) 0.1&#x2013;3.0 weight % of a non-siliconized organic fragrance solubilizer; wherein the composition is a gel having a viscosity greater than 150,000 centipoise and a ratio of oil phase to water phase in the range of 10:90 to 24:76.

High efficacy gel with low glycol content

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 is a clear stick or gel having low tack. The cosmetic sticks are formed as a one phase system by combining: (a) from 0.5-50 weight percent of a dimethicone copolyol ester compound soluble in propylene glycol; (b) from 50-99 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 solvent selected from the group consisting of polyhydric alcohols for example, propylene glycol; dipropylene glycol; tripropylene glycol; tetrapropylene glycol; PPG-10 butane diol; 1,3-butane diol; 2-methyl-1,3-propanediol; PEG-6; and PPG-425; optionally including up to 50 percent of other solvents selected from the group consisting of propylene carbonate, diisopropyl sebacate, methyl pyrrolidone, and ethyl alcohol as a substitute for a portion of the polyhydric alcohol component; and (c) an effective amount of at least one cosmetically active ingredient, for example, an antiperspirant active.
