  • Publication number: 20110009676
    Abstract: A process for the preparation of a 1-alkyl glycerol ether of the formula (I) in which: (a) an alkyl glycidyl ether of the formula (II) in which R is an unbranched or branched C1- to C24-alkyl group, where the alkyl group may be substituted with one or more hydroxy and/or C1- to C4-alkoxy group(s) and/or the alkyl chain may be interrupted by up to four oxygen atoms, is added to: (x) a carboxylic acid having 1-10 carbon atoms; (y) an ester of a carboxylic acid having 1-10 carbon atoms; and/or (z) an anhydride of a carboxylic acid having 1-10 carbon atoms. The low-water reaction mixture containing a catalytic amount of a strong acid is reacted at a temperature of more than 40° C. to give an acylated alkyl glycerol ether; and (b) the acylated alkyl glycerol ether is reacted in order to obtain the alkyl glycerol ether of the formula (I).

  • Publication number: 20110003857
    Abstract: An aqueous-based composition which includes a) at least one bispyridinium alkane (for example octenidine) and b) at least one stabilizer selected from antioxidants, complexing agents, reducing agents, UV filters and photoprotective agents, in particular ?-tocopherol, and BHT. The composition can also include c) one or more auxiliaries selected from, for example, nonionic surfactants, ethers, solvents and polymers, in particular fatty alcohol alkoxylates and alkoxylated fatty acid monoglycerides. The presence of the stabilizer reduces or prevents the appearance of decomposition products of bispyridinium alkanes and, in the case of the presence of auxiliaries, of decomposition products of the auxiliaries, such as ethers and peroxides.
