Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
124 words
Emulsifier for preparing dyeing accelerators (carriers) based on alkylnaphthalenes, consisting of a multi-component system of the following composition (weight percent): (a) 57.0 to 51.0% of a mixture of sulfonated and oxethylated alkylaryl compounds having in the alkyl radical from 9 to 12 carbon atoms, sulfonates to oxethylates 1.1 to 3:1, (b) 15.0 to 17.0% of aliphatic alcohols having from 3 to 5 carbon atoms, (c) 2.0 to 6.0% of sodium alkylsulfonamide acetic acid, (d) 2.0 6.06.0 % of partially chlorinated paraffin hydrocarbons having from 12 to 14 carbon atoms and 1.5% of chlorine, (e) 2.0 to 6.0% of olein and (f) 18.0 to 20.0% of water, whereby the individual quantities of the different components have to form a total of 100% in each case.
