Mixture of ionic polyethers of formula: <IMAGE> (I) where R denotes C1-C20 alkyl or alkenyl or C614 C20 aryl or aralkyl; z=1 or 2; y=3-20; T=0 or S; u=0 or 1; m=3-11; n=0-11; n NOTEQUAL 0 when u=1 and m+n>/=4; B=OH or A; A is an ionic group -COOM; -(CH2)u-S-(W)COOH (with W=-CH2-, -CH2-CH2- or -CH(CH3)- and u'=u); -CH2-O-S)3M, (M being an alkali metal or an ammonium ion optionally substituted by methyl, ethyl, hydroxyethyl, hydroxypropyol, methylhydroxypropyl or methyldihydroxypropyl); <IMAGE> +TR <IMAGE> (where R1, R2 and R3 denotes methyl, ethyl, hydroxyethyl or dihydroxypropyl, R1 and R2 being capable of forming with N an amino or ammonio heterocyclic ring, HV is an inorganic or organic acid and Q- is an anion); <IMAGE> HV (with R4=methyl or ethyl and x=2 or 3) <IMAGE> <IMAGE> with the provision that when T=0 and u=0, A denotes only (b); and process for preparing them. The new polyethers can be employed in cosmetics, pharmacy and the textile industry as a result of their good solubilising and stabilising capacity. |
