  • Publication number: 20110028766
    Abstract: The present invention relates to a process for converting at least one multihydroxylated-aliphatic hydrocarbon and/or an ester thereof to at least one chlorohydrin and/or an ester thereof, comprising at least one reaction step in which the multihydroxylated-aliphatic hydrocarbon and/or ester thereof is contacted with hydrogen chloride under reaction conditions to produce the chlorohydrin and/or ester thereof, followed by at least one downstream processing step in which the effluents of the reaction step are processed, wherein the downstream processing step is performed in such conditions that the effluents containing the chlorohydrin and/or ester thereof are kept at a temperature of less than 120° C. The invention allows to minimize the liberation of hydrogen chloride from the products of the hydrochlorination reaction, hence reducing the corrosion of the downstream equipment and reducing the need to use costly corrosion resistant materials.
    Type: Application

  • Patent number: 6537533
    Abstract: The invention relates to hair conditioner compositions that are non-irritating to the eye and which comprise: a) a C20-C24 quaternary ammonium compound, which has ethosulfate or methosulfate as an anion; b) a second C20-C24 quaternary ammonium compound, which has chloride or bromide as an anion; c) a compound which is solid at room temperature and which is selected from the group consisting of a fatty alcohol, an ester, an amine, an amide, an acid, and a water-soluble polymer; d) optionally a compound, which is liquid at room temperature, selected from the group consisting of a water insoluble emollient, a water insoluble lubricating agent, and a water insoluble conditioning compound; and wherein a) and b) are present in a weight ratio of about 1:10 to about 10:1; are described.
