Abstract:
Stable, topically applicable cosmetic/dermatological sunscreen compositions, well suited for the UV-photoprotection of human skin/keratinous materials, contain a thus effective amount of at least one novel amine, amide, sulphonamide or carbamate substituted benzalmalonic salt compound.
Abstract:
Cosmetic or pharmaceutical preparations, characterized in that they comprise an effective concentration of hydrophilic starch esterified with one or more n-octenylsuccinate radicals.
Abstract:
A process is provided for the production of glycogens or an extract rich in glycogens from yeast cells, and a cosmetic composition containing them. A given quantity of yeast cells, from a specific culture or recovered as residues of a fermentation process, is subjected to an operation of enrichment in intracellular glycogens by culturing in two phases in the presence of a carbon source. The metabolism of the yeast cells is then stopped. The membranes of the yeast cells are then at least partially disintegrated to free intracellular substances, and the freed intracellular substances are subjected to at least one precipation to precipitate glycogens. A cosmetic composition comprising the glycogens is formulated in admixture with a dermatologically acceptable excipient.
Abstract:
Disclosed herein are a highly purified tocopheryl phosphate and/or a salt thereof (tocopheryl phosphates) wherein a P,P'-bistocopheryl hypophosphate and/or a salt thereof (P,P'-bistocopheryl diphoshates) is contained in a proportion of not higher than 3% by weight; a process for producing a highly purified tocopheryl phosphate and/or a salt thereof, which comprises the steps of reacting a tocopherol with an oxyphosphorus trihalide followed by treating with an acid or basic aqueous solution to thereby form tocopheryl phosphates (i) in which P,P'-bistocopheryl diphoshates (ii) formed as by-products are contained, hydrolyzing the P,P'-bistocopheryl diphoshates (ii) under acid condition, and, optionally, rendering the hydrolyzate neutral or basic under basic condition; and a method of analyzing tocopheryl phosphates, comprising analyzing a sample containing components (i) and (ii) with the use of a high-performance liquid chromatograph column packed with a gel of a polymethacrylate having, bonded thereto, long-chain alkyl groups. None or only an extremely minute amount of P,P'-bistocopheryl diphoshates are contained in the highly purified tocopheryl phosphates, so that the highly purified tocopheryl phosphates exhibit antioxidant and blood circulation promoting effects, have excellent water solubility, are powdery so that the handling thereof is extremely easy, are free from cutaneous irritation and allergenecity and ensure dermal safety. Therefore, the highly purified tocopheryl phosphates are useful as cosmetic ingredients. The amounts of components (i) and (ii) can be simply measured with high accuracy by the above method.
Abstract:
The present invention relates to cosmetic or pharmaceutical compositions comprising a powder containing a water soluble carboxylated gum and a clay crosslinked with metal ions.
Abstract:
A powder for use in products which boast a protective factor against sunbeams or UV rays includes the following ingredients:a) 0.1-99.99% of a powder phase;b) 0.01-10% of a perfluoridated-derivatives phase;c) 0-5% of an agent coupling phases a) and b).The powder is particularly suitable for cosmetic products, particularly for make-up products.
Abstract:
A body powder composition useful for removing sand adhered to a user's body. The composition comprises a major amount of cornstarch. A related method for removing sand off the body is also disclosed comprising the steps of liberally applying a powder composition containing a major amount of cornstarch to an area of the body having sand adhered thereto; rubbing said composition on said area; and wiping said composition and said sand off the area using one's hands or a towel or the like.
Abstract:
A composition for topical application comprising at least one surfactant having a nitrogen atom in the moiety thereof and at least one compound selected from the group consisting of cyclohexane and the derivatives thereof, cyclohexene and the derivatives thereof, and cyclohexanone and the derivatives thereof.
Abstract:
This disclosure introduces the use of an isophorone diisocyanate urethane polymer of naturally occurring castor oil as an active ingredient for skin and personal care compositions and products.
Abstract:
The present invention provides novel cosmetic compositions for artificially tanning the skin utilizing skin tanning agents and cyclodextrins. The compositions are exceptionally stable and reduce the odor associated with the reaction between skin tanning agents such as dihydroxyacetone and the skin.
