  • Patent number: 6395301
    Abstract: An anhydrous hydrophobic cosmetic composition in the form of a compact powder which can be taken up in dry form or with water, comprising a particulate phase comprising hydrophilic pulverulent compounds, wherein the hydrophilic pulverulent compounds represent 20 to 35% by weight relative to the total weight of the particulate phase. The invention also relates to a make-up process using such a composition, as well as to a device comprising such a composition and a sponge which can be moistened.

  • Patent number: 6358493
    Abstract: Gasified particles for cosmetic treatments, particularly hair treatments, are described. The gasified particles contain at least one gas enclosed in a solid enveloping material. The enveloping material is selected so that the gas is released on contact of the enveloping material with water or moisture. The release of the gas can be accompanied by a detectable acoustic effect (pop effect). The hair treatment composition also can provide a hair fixing effect. Furthermore an instant gel preparation is described substantially comprising a mixture of dry substances, which contains at least one gel former and at least one solid substance producing a detectable acoustic effect on contact with moisture, especially gasified particles. The gasified particles are used as acoustic indicators for the readiness of the instant preparation after liquid addition.

  • Patent number: 6352704
    Abstract: A sterile or non-sterile flavored monomeric adhesive composition includes a flavoring additive and a monomer. The composition can be applied, for example, to skin or the inside of the mouth. A method of making a sterile, flavored adhesive composition includes placing a mixture of a polymerizable adhesive monomer and a flavoring additive in a container, sealing the container, and sterilizing the mixture and the container. The flavored adhesive composition is particularly useful as a medical adhesive and can include 1,1 -disubstituted ethylene monomers, such as &agr;-cyanoacrylates.

  • Patent number: 6335022
    Abstract: The present invention relates to a nanoemulsion, the oil globules of which have an average size of less than 100 nm, comprising (1) a surfactant which is solid at a temperature of less than or equal to 45° C., which surfactant is chosen from sorbitan fatty esters and oxyethylenated sorbitan fatty esters, (2) at least one oil having a molecular weight of greater than 400 and (3) at least one ionic amphiphilic lipid chosen from the group formed by the alkaline salts of dicetyl and dimyristyl phosphate, the alkaline salts of cholesterol sulphate, the alkaline salts of cholesterol phosphate, lipoamino acids, the sodium salts of phosphatidic acid, cationic amphiphilic lipids and alkylsulfonic derivatives, the ratio by weight of the amount of oily phase to the amount of surfactant ranging from 2 to 10. The surfactant used is, for example, chosen from sorbitan monostearate, sorbitan monopalmitate and sorbitan 20 EO tristearate. The emulsion obtained is transparent and stable on storage.

  • Patent number: 6328950
    Abstract: The pigment-containing foamable gel for temporarily coloring the hair contains from 35 to 98 percent by weight water; one or more gel-forming thickener that imparts a yield point to the composition; at least one pigment; at least one film-forming, hair-fixing polymer; at least one foam-producing surfactant and at least one propellant, in combination with a suitable aerosol package and a foam-forming device for foaming the gel. The concentration of the thickener or thickeners in the gel is selected so that, on the one hand, the viscosity of the gel is sufficiently reduced so that foaming of the gel is possible and, on the other hand, the yield point is at least large enough so that settling of the pigment is prevented. The easily foamable composition has a hair-fixing effect and temporarily colors the hair, providing a high color brilliance and lustrous appearance. The composition is washable from the hair at will and the color of the hair provided by it has good fastness to rubbing.

  • Patent number: 6328951
    Abstract: Described is a water-soluble solid-phase ironing aid-freshening composition for use in forming controllably dimensioned tablets, which have controlled weights and densities and which are conveniently added to the water-containing steam chamber of a steam iron. The use of the tablets produced from the composition enables textiles which are ironed to be freshened and de-wrinkled. The composition includes (i) a support substance; (ii) a tablet binder substance; and (iii) a fragrance composition and, optionally, a silicone resin, a chelating agent and/or a surfactant.

  • Patent number: 6303662
    Abstract: A microemulsion containing (A) a highly polar and fat-soluble oil drug, a highly polar oil and a lowly polar oil, (B) a polyglycerol mono-fatty acid ester and (C) a water-soluble polyhydric alcohol, wherein the amount of (B) is 0.3 to 3 parts by weight based on one part by weight of (A) and the amount of (C) is 0.1 to 3 parts by weight based on one part by weight of the total amount of (A) and (B). The present invention makes it possible to make a microemulsion containing a highly polar and fat-soluble drug which is highly stable.
