  • Patent number: 11065191
    Abstract: Process for thickening a composition, through the use of a direct emulsion in water, which is alkali-swellable, of a polymer of the ASE or HASE type, which is both rich in acrylic acid and which has a certain quantity of AMPS. The use of such emulsions simultaneously allows there to be no obligation to use surfactants and organic solvents other than water, and allows the thickening phenomenon to be activated for pHs of less than 7: this latter characteristic is particularly advantageous for formulations intended to be used in contact with skin.

  • Patent number: 10517292
    Abstract: The invention relates to paintball-pellet-type projectiles containing insect pheromones encapsulated in an aqueous oil-in-water-type formulation. Said formulations can release said pheromones in a sustained manner. Said projectiles are characterised in that they contain the aqueous formulation of encapsulated pheromone compatible with the envelope of the projectile composed of oxo-degradable polymer. The aim of the invention is to use said projectiles to treat trees against insect pests by spraying and bursting said projectiles on the trunks of said trees.

  • Patent number: 9790171
    Abstract: The subject matter of the present invention is the novel molecules of formulae E, E? and F. These molecules prove to be synthesis intermediates that are very advantageous for the manufacture of derivatives of sphingosine or of ceramides functionalized in position 1, with good yields, in which R1 and R2 are fatty chains, R3 is an alkyl group and R4 is a protective group for alcohol functions. Another subject of the invention is the use of the intermediates of type F for converting same into intermediates of type G, by means of reduction in the presence of lithium borohydride. The G molecules are precursors that are known to make it possible to obtain sphingolipids or sphingomyelin.
