Abstract: Novel compounds of formula (I):

Abstract: The present invention relates to a novel family of compositions based on alkylpolyglycosides and dimerdiol, which are especially useful for the preparation of vaporisable oil-in-water emulsions.

Abstract: The present invention relates to a novel family of compositions based on alkylpolyglycosides and fatty diols, which are especially useful for the preparation of emulsions which are stable and which possess a good opaque-making effect. According to the invention, these compositions comprise: 5 to 95 parts by weight of a mixture of alkylpolyglycosides which is constituted of the products of a reaction of a saccharide and 1,12-octadecanediol; 95 to 5 parts by weight of 1,12-octadecanediol.

Abstract: A microparticle comprising an active substance which is a central core made of liquid, gaseous or solid particle of regular or irregular shape, and the method for entrapping said active substance in a coating material which is conformationally distributed on said active substance and has a thickness ranging from the thickness of a monomolecular layer to about 100 .mu.m. These compositions are useful for applications that require protection, prolonged release, taste masking, improved stability, altered handling behavior, altered surface properties including particle wettability, and other desirably altered properties.

Abstract: A process for the preparation of an alkylpolyoside containing from 6 to 32 carbon atoms in its alkyl chain, by the steps of:a) reacting, in the presence of an acid catalyst, a saccharide or a source of saccharide with a fatty alcohol having a hydrocarbon chain containing at least 6 carbon atoms, or a lower alcohol of the formula C.sub.n H.sub.2n+1 OH, in which n is an integer between 1 and 5, and a fatty alcohol having a hydrocarbon chain containing at least 6 carbon atoms;b) neutralizing the catalyst used in step a); andc) removing excess fatty alcohol. The neutralizing takes place using a neutralizing agent which is a tertiary amine of the formulae ##STR1## in which: --m is an integer between 0 and 5; andR.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which are identical or different, are independently:an alkyl radical having from 1 to 6 carbon atoms,a hydroxyalkyl or dihydroxyalkyl radical having from 2 to 4 carbon atoms,a phenyl radical, ora radical of the formula (C.sub.n H.sub.2n --O).sub.
