Abstract:
The present invention relates to the use as a preserving agent, in particular in cosmetic or dermatological composition, of at least one compound of formula (I): in which : - X represents =O or -OH; - R1 represents a hydrogen atom or a methyl; - R2 represents a hydrogen atom, a methyl or an ethyl; - R3 represents a C1 -C12, saturated or unsaturated, linear hydrocarbon-based radical, optionally substituted with a hydroxyl group (OH); with the exclusion of the compound of formula (I) in which X represents =O, R1 = methyl, R2 = H and R3 = -(CH 2 ) 6 -CH 3 . The invention also relates to certain novel compounds and to the cosmetic or dermatological compositions comprising same.
Abstract:
The element comprises: - a hollow body (19); - a delivery nozzle (32) for delivering a first liquid carried by the hollow body (19); - a dispensing nozzle (50) for dispensing a second liquid carried by the hollow body (19); The dispensing nozzle (50) is suitable for producing droplets having a diameter less than 1 mm, particularly comprised between 1 μm and 1000 μm and the delivery nozzle (32) is suitable for producing droplets having a diameter greater than 1 mm, and particularly comprised between 1 mm and 5 mm.
Abstract:
The element comprises: - a hollow body; - a receptacle (40) for receiving a cosmetic product, housed in the hollow body; - a conduit (42) for supplying water into the receptacle (40); - a nozzle (50) for dispensing the mixture of water and cosmetic product from the dispensing element. The element comprises an inner water dispensing nozzle (44), connected to the water supply conduit (42), the inner nozzle (44) protruding into the receptacle (40) to define a chamber (46) for mixing water and the cosmetic product contained in the receptacle (40).
