  • Patent number: 5368842
    Abstract: The present invention embraces an aerosol antiperspirant composition which comprises a suspension of about 5 to 15% high efficacy aluminum salt in powder form in about 15 to 35% volatile silicone and about 40 to 80% liquefied hydrocarbon propellant with about 0.7 to 1.5% hydrophobic colloidal silica suspending agent and about 0.15 to 0.35% hydrophilic colloidal silica suspending agent. The composition of the present invention has superior antiperspirant efficacy and avoids the use of materials which have an adverse effect on efficacy, namely oil soluble emollient esters such as isopropyl myristate and polar agents such as ethanol.

  • Patent number: 5356612
    Abstract: Antiperspirant effectiveness of basic aluminum chloride is increased by mixing it with monosilicic acid in aqueous solution. The product can be dried to a solid, and the antiperspirant effectiveness does not decrease in contact with water. The product can also be characterized by size exclusion chromatography of its approximately 10% by weight aqueous solution. Zirconyl hydroxy chloride may also be present.

  • Patent number: 5340571
    Abstract: The present invention comprises a non-aerosol shaving composition in the form of a clear gel comprising in percent by weight, with the balance being water,(a) about 15 to 20% of a mixture of potassium myristate and potassium palmitate wherein the myristic acid to palmitic acid ratio is about 2 to 1;(b) about 2 to 4% Oleth-20;(c) about 1 to 5% sodium lauroyl sarcosinate; and(d) about 1 to 2% hydroxyethylcellulose, about 1 to 3% sorbitol, and about 1 to 2% PEG-150 distearate. This composition provides superior shaving attributes compared to other non-aerosol shaving products.

  • Patent number: 5298640
    Abstract: A composition of zirconyl hydroxy chloride and aluminum chlorhydroxide in stable solid form having improved antiperspirant efficacy when dissolved in water is made by heating a 2-20% by weight aqueous solution containing at least the aluminum chlorhydroxide component of the composition at a temperature of at least 50.degree. C. until the ratio of the height of peak 4 at Kd=0.7 to that of peak 3 at Kd=0.5 as measured by gel permeation chromatography on cross-linked dextran is at least 2:1, then subjecting the solution to rapid drying to solid form.

  • Patent number: 5294230
    Abstract: Hair is waved or straightened by maintaining it in tightly curled or in straightened configuration in contact with an aqueous waving lotion containing sulfite, bisulfite, or hydrosulfite together with a water-soluble mercaptan, at a molar ratio of 5:1 to 1:7.5, rebuilding with an aqueous lotion at pH 7 to 12 free from cross-linking, oxidizing, or reducing agents, and subsequently applying a neutralizer solution. Minimal damage to the hair results from use of the specified molar ratio. When waving hair, an optional additional step between cross-linking and neutralizing comprises maintaining the rebuilt hair in stress-free condition in contact with the ambient atmosphere to permit the curled hair to relax to the desired extent.

  • Patent number: 5279819
    Abstract: An improved instant foaming aerosol shave cream is provided which includes, in percent by weight of the entire composition, (a) about 70--90% water, (b) about 10-20% of a soap component comprising about 8-12% of an alkanolamine C.sub.14 -C.sub.18 fatty acid soap and about 2-4% of a nonionic surfactant having an HLB of at least about 15, (c) about 1-5% of a propellant having a vapor pressure of about 30-60 Psig at 70.degree. F., (d) about 0.1-5% of one or more emollients, and (e) about 0.3-4% of a foam stabilizer component comprising about 0.1-3% of a fatty alcohol, about 0.1-3% of a fatty alkanolamide, and about 0.01-0.6% of a fatty acid diester of polyethylene glycol having a molecular weight of at least about 1000. The compositions are oil-in-water emulsions and exhibit advantages associated with delayed-foaming shaving gels but with the convenience of instant foams.
