摘要： The present invention relates to sulfate-free aqueous personal care composition comprising a surfactant system comprising at least one methyl oleoyl taurate, one isethionate and one alkoxylated sulfosuccinate, and from about 0.2 pbw to about 15 pbw of a conditioning agent. It is also directed toward the use of such a composition for washing keratin substrates, in particular the hair or the scalp.

摘要： A method for the selective cleavage of a compound comprising an aromatic ring and a C—O—C linkage in the presence of a heterogeneous catalyst is provided. The heterogenous catalyst may be a supported noble metal catalyst doped with a halogen selected from the group consisting of chlorine and bromine. By using this method, it is possible to increase the selectivity and/or yield (preferably both) of aromatic compounds.

摘要： The present invention pertains to a process for the cross-ketonization (Piria reaction) between an aryl carboxylic acid and an aliphatic carboxylic acid using a metal-based compound and a slight or a moderate excess of aryl carboxylic acid. A good selectivity, up to 99 mol %, can be achieved. The aryl aliphatic ketone can be used for the preparation of surfactants and other downstream products.
