Abstract: A new method of forming agglomerates of fine powdered solids comprises dispersing the powder in a chemically inert carrier liquid that also contains a dissolved binder precursor polymer with cyclic dicarboxylic acid anhydride groups on the polymer chain. The dispersion is shaped and then brought into contact with a second carrier liquid that contains polyamines. The polyamines react with the anhydride groups on the other polymer to form an insoluble binder polymer that hardens the shaped dispersion. The hardened shape can then be separated from the liquids and/or further reacted if desired to produce amide bonds in the final agglomerates. The method is useful for forming mechanically and thermally stable agglomerates of such materials as activated carbon, metals dispersed on catalyst carriers, etc.

Abstract: Cosmetic emulsions of the oil-in-water type which are pourable at 20.degree. C. contain as an oil component dialkyl ethers corresponding to the formula R.sup.1 --O--R.sup.2, in which R.sup.1 and R.sup.2 independently of one another represent a linear or single-branch C.sub.6-22 alkyl. Even a content of only 0.5 to 5% by weight of dialkyl ethers can considerably reduce the viscosity of the emulsions. Preferred emulsions contain from 1 to 30% by weight of discontinuous lipophilic phase and from 70 to 99% by weight of continuous aqueous phase.

Abstract: An improvement in the process of extraction of amino acids from aqueous solutions in which the amino acids are extracted with quaternary ammonium extractants. A pretreatment of the amino acid containing aqueous solution with a tertiary amine prior to extraction of the amino acids with the quaternary ammonium extractant, removes some impurities or poisons present therein, leaving the amino acids in the aqueous solution for subsequent extraction with a water insoluble quaternary ammonium extractant. After extraction with the quaternary extractant, the organic phase is stripped of amino acid and the stripped organic is subjected to an acidic scrub before returning to the quaternary extraction stage.
