  • Publication number: 20200345616
    Abstract: The present invention relates to a composition comprising a polymer, wherein this polymer is water-soluble and has a melting point of at least 145° C. and comprises sulfonic acid groups, and an organic amine having at least two amino groups, and optionally further cosmetic ingredients. Furthermore, the present invention relates to a process for restyling human hair comprising applying to the human hair a composition comprising a polymer, wherein this polymer is water-soluble and has a melting point of at least 145° C. and comprises sulfonic acid groups, and an organic amine, and optionally further cosmetic ingredients, thereafter heat-treating the hair, together with the composition on its surface, thereafter allowing the hair to cool down to a temperature of below 100° C., and thereafter changing the hair style by heat-treating the hair. Furthermore, the present invention relates to the use of the said polymer or of the said composition for restyling human hair.

  • Patent number: 8586063
    Abstract: Disclosed are compounds obtained by reacting (a) epoxides (I) which comprise at least two epoxide groups per molecule, with (b) compounds of the structure (II), having substituents as defined, and (c) optionally, alcohols (III) of the formula R4—OH, wherein R4 is C6-C22 alkyl, with the proviso that the molar ratio of the reactants (I):(II):(III) is in the range from 1:(1 to 3):(0.05 to 1.95). These compounds are useful as thickeners, and may be prepared as thickener concentrates.

  • Publication number: 20120172618
    Abstract: Novel compounds having the structure (I) are provided, where R1 represents hydrogen, an alkyl group containing 1 to 3 C atoms, or a group R3; R2 represents an alkyl group containing 2 to 22 C atoms, wherein said group can be linear, branched, or cyclic and saturated or olefinically mono- or polyunsaturated; R3 represents a saturated alkyl group containing 1 to 3 C atoms, wherein said alkyl group is substituted by a group —O—(CH2—CHZ—O)p—H at one of the C atoms; X, Y, and Z independently represent hydrogen or a methyl group; and n and m independently represent a number ranging from 1 to 45, and p represents a number ranging from 0 to 45, provided that the sum of n+m+p has to range from 2 to 70. The compounds having structure (I) are excellent low-foaming surfactants.
