  • Patent number: 6936242
    Abstract: Disclosed is a non-flowable anhydrous topical antiperspirant composition comprising a first portion and a second portion contiguous with the first portion. The first portion is semi-opaque to opaque and comprises a first hydrophobic carrier vehicle and a first gellant and has a particulate antiperspirant active suspended therein. The second portion is translucent to transparent and comprises a second hydrophobic carrier vehicle and a second gellant. Preferably, the second hydrophobic carrier vehicle has an average refractive index that approximately matches the refractive index of the second gellant. Ideally, for greater translucency the second portion will be substantially free of antiperspirant salt and/or other opacifying materials. Preferably, the first hydrophobic carrier vehicle also has an average refractive index that approximately matches the refractive index of the first gellant.

  • Patent number: 6375938
    Abstract: The present invention embraces an anhydrous topical antiperspirant or deodorant composition comprising an antiperspirant or deodorant active, a dermatologically acceptable volatile silicone liquid carrier vehicle and a polyethylene homopolymer dissolved in the vehicle to serve as a thickening or solidifying agent, wherein the polyethylene homopolymer has a molecular weight of about 200 to about 800 daltons, preferably about 300 to about 600 daltons, most preferably about 400 to about 500 daltons. The composition should be substantially free of any other organic or natural waxes. The present invention also embraces a method of inhibiting or reducing perspiration or a method of inhibiting or reducing malodor by topically applying an effective amount of such an antiperspirant composition or deodorant composition to the skin.

  • Patent number: 6051216
    Abstract: An invention is disclosed which comprises siloxane-based polyamides as gelling agents for cosmetic products, methods for making such agents, formulations therof and cosmetic formulations therewith. These polyamides contain siloxane groups in the main chain and act to thicken compositions containing volatile and/or non-volatile silicone fluids. Cosmetic compositions may be made by adding at least one active ingredient such as an antiperspirant.

  • Patent number: 5017302
    Abstract: A bar soap prepared from a tallow-coco soap chip base containing minor amounts of filler, dye and water and from 1 to 5 percent straight chain primary alcohol elected from the group consisting of stearyl alcohol, cetyl alcohol (1 hexadecanol) and myristyl alcohol, to reduce or eliminate wet cracking of the bar during use.

  • Patent number: 4466342
    Abstract: An improvement in a pressurizable container used to prepare a carbonated beverage from a water-based liquid and carbon dioxide generating chemical reactants comprises the use of a carbonation chamber having an upper compartment for holding the chemical couple and a lower compartment with a bottom sparger surface for releasing, as uniformly small bubbles, the generated carbon dioxide into a beverage to be carbonated. The bottom sparger surface permits the rapid carbonation of a beverage without agitation and also minimizes the transfer of the resultant products of the chemical reaction to the beverage.

  • Patent number: 4458584
    Abstract: A substantially salt-free carbonated beverage is produced using a pressurizable container comprising a carbonation chamber having an upper compartment for holding the chemical reactants, a means for separating gaseous carbon dioxide and solid or liquid reaction by-products and a lower compartment having a bottom sparger surface for releasing, as uniformly small bubbles, the generated carbon dioxide into a liquid to be carbonated. The separation means and sparger surface function to retain the chemical by-products of the reaction from the carbonated beverage.
