  • Publication number: 20100286009
    Abstract: The invention refers to lubricant compositions, said lubricant compositions being particularly preferred for conveyor systems, especially in the foodstuff industry, which are suitable for lubricating, cleaning and disinfecting of the transport chains. More specifically, the invention refers to lubricant compositions for conveyor systems comprising: a) one or more phosphoric acid esters; and b) one or more ether carboxylates; and e) water; and c) one or more C6-C22 fatty acids, optionally ethoxylated with to 20 moles of ethylene oxide; and/or d) one or more C6-C22 fatty alcohols, optionally ethoxylated with 1 to 20 moles of ethylene oxide wherein the weight ratio of component (a) to component (b) is in the range of 9:1 to 1:3. Said lubricant compositions can be used in conveyor systems for glass and/or plastic bottles, such as polyethylen terepthalate (PET) or polycarbonate (PC); cans, glass containers, drums, cardboard containers and similar items.

  • Publication number: 20050262643
    Abstract: The present invention discloses the use of ethercarboxylates for lubricating textile fibres, preferably spinning fibres. These ethercarboxylates have the general formula (I) R—(OCH2CH2)n—O—CH2COOX??(I) where: R represents a C6-C22 aliphatic hydrocarbon chain, saturated or unsaturated, linear or branched, n is a number between 0.3 and 50, X is hydrogen, an alkali metal, an ammonium cation, an alkanolammonium cation or a C6-C22 alkylammonium cation. In addition, the present invention provides a process for lubricating textile fibres that consist of placing in contact these textile fibres with ethercarboxylates of general formula (I).

  • Publication number: 20050235430
    Abstract: New dyeing compositions, containing improved levelling agents, for dyeing of keratinous fibres, especially human hair, making more uniform the colour of the dyed fibres, are provided. The compositions contain one or more compounds of the formulae (I) and/or (II), wherein R is an alkyl group or alkenyl group having 6 to 24 carbon atoms; R?, R? and R?? are independently a hydrogen atom or an alkyl group having 1 to 5 carbon atoms which is optionally hydroxylated; m has a value in the range of 4 to 10; n has a value in the range of 0 to 10; and p has a value in the range of 1 to 10, with the proviso that when p=1, at least one of R?, R? and R?? is not a hydrogen atom.
