  • Publication number: 20060287516
    Abstract: A process for producing aminoalkyl-containing guar derivative is disclosed. The process entails a) dispersing a member selected from the group consisting of guar and guar derivative in a mixture of a water-miscible aprotic solvent and water and b) alkalyizing the member with a base to obtain a mixture containing an alkalized member and c) etherifying the mixture with an amino-containing reagent to obtained an etherified mixture and d) optionally neutralizing the etherified mixture to obtain a material system containing a reaction product and e) optionally filtering the material system to obtain the reaction product and f) optionally washing the reaction product and g) optionally drying the reaction product referred to in f) and h) optionally grinding the reaction product. The product thus obtained is suitable for producing hair conditioners and flocculation aids.

  • Publication number: 20060117998
    Abstract: An anionic cellulose nitrate derivative is described, which has: (i) a degree of acid group substitution (DS (acid)) in the range of 0.01 to 0.2; and (ii) a nitrogen content of 10.7 wt. % to 12.3 wt. %, based on the weight of cellulose nitrate derivative. The anionic cellulose nitrate derivative is prepared by a process which includes esterifying cellulose nitrate feed material with at least one dicarboxylic acid anhydride (e.g., maleic anhydride). Aqueous dispersions according to the present invention include: (a) at least on anionic cellulose nitrate derivative according to the present invention; and (b) at least one base.
