Cleaning compositions containing hydroxy mixed ethers, methods of preparing the same, and uses therefor

   
   

Cleaning compositions containing hydroxy mixed ethers of the general formula (I) are described: R.sup.1 O[CH.sub.2 CHR.sup.4 O].sub.x [CH.sub.2 CHR.sup.3 O].sub.y CH.sub.2 CH(OH)R.sup.2 (I) wherein R.sup.1 represents an alk(en)yl radical having from 4 to 22 carbon atoms; R.sup.2 represents an alk(en)yl radical having from 2 to 22 carbon atoms; R.sup.3 represents a hydrogen or a methyl radical; R.sup.4 represents a hydrogen or a methyl radical; x is from 1 to 40; y is from 1 to 40; and x+y>=1; and wherein the alkylene units --CH.sub.2 CHR.sup.3 O-- and --CH.sub.2 CHR.sup.4 O-- are in randomized form, preferably in an ethylene oxide to propylene oxide ratio of from 40:1 to 40:5. Methods of preparing and using the hydroxy mixed ethers are also described.

Las composiciones de la limpieza que contienen los éteres mezclados hydroxy del fórmula general (i) se describen: R.sup.1 O[CH.sub.2 CHR.sup.4 O].sub.x [ CH.sub.2 CHR.sup.3 O].sub.y CH.sub.2 CH(OH)R.sup.2 (i) en donde R.sup.1 representa un alk(en)yl radical teniendo a partir 4 a 22 átomos de carbón; R.sup.2 representa un alk(en)yl radical teniendo a partir 2 a 22 átomos de carbón; R.sup.3 representa un hidrógeno o un radical metílico; R.sup.4 representa un hidrógeno o un radical metílico; x es a partir la 1 a 40; y es a partir la 1 a 40; y x+y = 1; y en donde las unidades del alkylene -- CH.sub.2 CHR.sup.3 O -- y -- CH.sub.2 CHR.sup.4 O -- están en forma seleccionada al azar, preferiblemente en un óxido del etileno al cociente del óxido del propylene de a partir la 40:1 a 40:5. Los métodos de preparar y de usar los éteres mezclados hydroxy también se describen.
