The mercerizing of cellulose fibers is improved by using an aqueous alkaline bath composition having as a wetting agent alkali salts of alkene sulfonic acids having 6 to 10 carbon atoms and single or double branched structures in a concentration of about 1 to 5 grams per liter of bath composition.

Alkaline baths containing alkene sulfonates as wetting agents

Method for the preparation of aqueous, finely dispersed, shelf-stable silicone oil emulsions with the use of emulsifiers. Dimethyl polysiloxanes and 0.1-0.3 part by weight of emulsifiers, based on the dimethyl polysiloxanes, of a monoester or diester of orthophosphoric acid or mixtures thereof, are mixed, with agitation at temperatures of between 20.degree. and 150.degree. C. until a clear solution is obtained; thereupon an organic base or alkali is added up to neutralization; and subsequently the neutralized mixture is diluted with water. The monoesters and diesters of orthophosphoric acid and mixtures thereof comprising the emulsifiers are prepared by the reaction of:
