Abstract: A composition useful as a tightening agent for decreasing or removing signs of aging, particularly for reducing or removing wrinkles and/or fine lines or to smooth out human skin. This composition comprises at least one grafted silicone polymer which itself comprises a polysiloxane portion and a portion composed of a non-silicone organic chain, one of the two portions constitutes the main chain of the polymer and the other is grafted to said main chain. Processes for the cosmetic treatment of aged skin, in particular wrinkled skin, comprising the application of an effective amount of the composition as defined above to achieve improvement in the appearance of rough, damaged or aged skin, or achieve softening the wrinkle by a tightening effect.

Abstract: The present invention relates to an anti-wrinkle composition containing a dispersion of a polymer system comprising at least one polymer of natural origin, and to the use of this polymer system as a tensioning agent in a cosmetic or dermatological composition. The polymer used must characteristically have a molecular weight of greater than 670,000 daltons and the polymer system obtained must be capable of forming a steam-permeable film, it must have a Young's modulus ranging from 108 to 9×109 N/m2 and it must produce, at a concentration of 7%, a greater than 1.5% retraction of isolated stratum corneum at 30° C. and at a relative humidity of 40%. The composition obtained is used in particular for the immediate treatment of wrinkles and fine lines on the skin.

Abstract: A nail treatment composition comprising hydroxy carboxylic acid.

Abstract: Novel 4,4-dihydroxy-5-pyrazolinones having the structural formula (I): ##STR1## and cosmetic/dermatological formulations comprised thereof are useful for artificially coloring, e.g., tanning/browning, human skin and/or hair, and are well suited for imparting a healthy appearance to facial skin by enhancing the radiance of the complexion, while at the same time retaining transparency.

Abstract: The use of colloidal silicic acid as strengthening agent in a composition comprising at least one film-forming material and at least one solvent, particularly an organic, aqueous or oily solvent.

Abstract: A nail treatment composition comprising hydroxy carboxylic acid.

Abstract: A pressurized container includes a dispenser which releases liquid contents from the container into the atmosphere in the form of an aerosol spray by way of a discharge nozzle. Additional gas is injected into the dispenser under pressure and discharged with the spray to enhance the finely divided nature of the spray particles and to render more uniform the rate of discharge of the liquid contents as emptying of the container takes place. The container for the liquid product may be pressurized by a non-liquefied gas, for example carbon dioxide gas, and the additional gas may be supplied from a container of liquefied additional gas or a container of additional gas dissolved in a solvent medium.
