The invention describes a process for the preparation of novel surfactant alcohols and surfactant alcohol ethers by derivatization of olefins having from about 10 to 20 carbon atoms or of mixtures of such olefins to give alkanols, and optional subsequent alkoxylation, which comprises subjecting a C-olefin mixture to metathesis, dimerizing the resulting olefins, and then derivatizing them to give surfactant alcohols, and optionally alkoxylating said alcohols. The olefin mixture obtained in the dimerization has a high proportion of branched components and less than 10% by weight of compounds which contain a vinylidene group. invention further describes the use of the surfactant alcohols and surfactant alcohol ethers to give surfactants by glycosylation or polyglycosylation, sulfation or phosphation.

Polyacetals containing acetaldehyde acetal units, preparation thereof

Polyacetals useful as reduced-phosphate or phosphate-free detergent and cleaner additives are obtainable by cationically initiated polyaddition of

Polyacetals based on divinyl ethers, dihydroxy compounds and monohydroxy

A stable liquid detergent composition having improved clay soil detergency, clay soil anti-redeposition, oily soil anti-redeposition and soil release properties is disclosed. The detergent composition is comprised of an anionic surfactant, a nonionic surfactant, a hydrotrope, a graft copolymer of polyalkylene oxide and an ester monomer, and a nonionic cellulosic anti-redeposition agent. The graft copolymer is comprised of (a) a polyalkylene oxide based upon an alkylene oxide having from 2 to 4 carbon atoms having a molecular weight of 300 to 100,000 and, (b) at least one vinyl ester derived from a saturated monocarboxylic acid containing 1 to 6 carbon atoms, and/or methyl or ethyl ester of acrylic or meth-acrylic acid in a weight ratio of (a):(b) of from 1:0.2 to 1:10. The nonionic cellulosic anti-redeposition agent is preferably hydroxypropyl methylcellulose. There is a synergism between the nonionic anti-redeposition agent and the graft polyol which imparts improved clay soil detergency, clay anti-deposition and oily soil anti-redeposition properties to the detergent composition.

Stable liquid detergent compositions with enchanced clay soil detergency

Pulverulent or water-free liquid detergents each essentially contain surfactants, builders, bleaching agents and effective amounts of compounds of the formula ##STR1## where R.sup.1 is for example C.sub.1 -C.sub.8 -alkyl, substituted or unsubstituted alkyl or C.sub.3 -C.sub.8 -alkenyl, and R.sup.2 and R.sup.3 are each for example H or C.sub.1 -C.sub.16 -alkyl, as bleach activators for peroxides.

Detergents that contain acyl derivatives of dihydroxydioxane as bleach

Long-chain alkylglucosides are purified by extraction with water from reaction mixtures obtainable by reacting monosaccharides and alcohols of 8 or more carbon atoms or by transacetalating short-chain alkylglucosides with alcohols of 8 or more carbon atoms, adjusted to a pH above 6 in either case.
