Description: PROCESS FOR PREPARING ETHER-CAPPED POL Y(OXY ALKYLATED) ALCOHOL SURFACTANTS Technical Field The present invention relates to a process for preparing low-foaming nonionic surfactants and more particularly to a process for preparing ether-capped poly(oxyalkylated) alcohol surfactants which have superior spotting and filming benefits in dishwashing and hard surface cleaning applications, as well as suds suppression in detergent compositions. Background of the Invention Due to the varied nature of different cleaning compositions, different surfactants are better suited for some applications while being less suited or totally unsuitable for other applications. Nonionic surfactants, such as alcohol ethoxylates, and alkyl glucose amides are of considerable importance in detergent products. For example, under some conditions, nonionic surfactants aid cleaning of greasy soils and inhibit the formation of calcium soap. However, conventional nonionic surfactants designed for effective cleaning in laundry products form liquid crystalline phases on mixing with water. These phases can hinder the rate of mixing with water and lead to undesirable optical properties of thin films on solution drying. For example, conventional nonionics sprayed on the surface of granules to achieve target density can give rise to poor granule dissolution and residue in horizontal axis machine dispensers. Conventional nonionics formulated at high levels in liquid products can lead to poor rates of mixing with water and consumer concern. Conventional nonionics in window and floor cleaners can form visible liquid crystalline films on drying that increase the effort required by the consumer to achieve good results. Similarly, a nonionic surfactant for use in an automatic dishwashing machine would need to minimize foam production and not leave undesirable spots and films on the cleaned surfaces. On account of the foregoing technical constraints as well as consumer needs and demands, product compositions are undergoing continual change and improvement. Moreover environmental factors such as the need for biodegradable materials, the restriction of phosphate, the desirability of providing ever-better cleaning results with less product, providing less thermal energy demand, and less water to assist the washing process, have all driven the need for improved compositions. Accordingly, the need remains for new surfactants which are suitable for use in a variety of compositions which can provide improve dissolution of solid products (like bars and tablets) and granular products, improved rates of mixing with water as with liquid products, improved streaking and filming performance as in hard surface cleaners and automatic dishwashing, good cleaning, suds control and good biodegradability while avoiding incompatibility with other cleaning surfactants and/or bleach.

The surfactant has the formula: wherein, R is selected from the group consisting of linear or branched, saturated or unsaturated, substituted or unsubstituted, aliphatic or aromatic hydrocarbon radicals having from about 1 to about 30 carbon atoms; R 1 may be the same or different, and is independently selected from the group consisting of branched or linear C 2 to C alkylene in any given molecule; x is a number from 1 to about 30; and R 2 is selected from the group consisting of: (i) a 4 to 8 membered substituted, or unsubstituted heterocyclic ring containing from 1 to 3 hetero atoms; and (ii) linear or branched, saturated or unsaturated, substituted or unsubstituted, cyclic or acyclic, aliphatic or aromatic hydrocarbon radicals having from about 1 to about 30 carbon atoms; provided that when R 2 is (ii) then either at least one of R 1 is other than C to C alkylene or R has from 6 to 30 carbon atoms.

Preparation of LAS Powder for Use as a Structurant Sodium C12 linear alkyl benzene sulfonate (NaLAS) is processed into a powder containing two phases. One of these phases is soluble in the non-aqueous liquid detergent compositions herein and the other phase is insoluble. It is the insoluble fraction which serves to add structure and particle suspending capability to the non-aqueous phase of the compositions herein. NaLAS powder is produced by taking a slurry of NaLAS in water (approximately 40-50% active) combined with dissolved sodium sulfate (3-15%) and hydrotrope, sodium sulfosuccinate (1-3%). The hydrotrope and sulfate are used to improve the characteristics of the dry powder. A drum dryer is used to dry the slurry into a flake. When the NaLAS is dried with the sodium sulfate, two distinct phases are created within the flake. The insoluble phase creates a network structure of aggregate small particles (0.4-2 um) which allows the finished non-aqueous detergent product to stably suspend solids. The NaLAS powder prepared according to this example has the following makeup shown in Table I. TABLE I LAS Powder Non-aqueous based heavy duty liquid laundry detergent compositions which comprise the capped nonionic surfactants of the present invention are presented below. The resulting compositions are stable, anhydrous heavy-duty liquid laundry detergents which provide excellent rates of mixing with water as well as good stain and soil removal performance when used in normal fabric laundering operations.
