Abstract: A system and method for balancing flows of renal replacement fluid is disclosed. The method uses pressure controls and pressure sensing devices to more precisely meter and balance the flow of fresh dialysate and spent dialysate. The balancing system may use one or two balancing devices, such as a balance tube, a tortuous path, or a balance chamber.

Abstract: A process for imparting curl retention onto hair involving (a) forming a hair fixative, said hair fixative containing: (i) an alkyl polyglycoside having general formula I: R1O(R2O)b(Z)a  I wherein R1 is a monovalent organic radical having from about 6 to about 30 carbon atoms; R2 is divalent alkylene radical having from 2 to 4 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; b is a number having a value from 0 to about 12; a is a number having a value from 1 to about 6; and (ii) a solvent; and (b) applying said hair fixative onto said hair.

Abstract: A pearlizing agent for such products as shampoos and hand soaps contains a glycol distearate, an alkyl polyglycoside, a betaine of the formula II ##STR1## wherein R.sup.5 is an alkyl or alkenyl group having from 7 to 21 carbon atoms and R.sup.6 is alkylene group having from 2 or 3 carbon atoms; each of R.sup.3 and R.sup.4 is independently an alkyl group having from 1 to 4 carbon atoms, a glycol, and water.

Abstract: Foaming shampoo compositions which contain no anionic surfactant and are mild to the skin and eyes are comprised of alkyl polyglycosides, betaines, and polymeric slip agents.
