Problems solved by technology

[0007] An additional problem arises under stress: the formation of larger ordered aggregates of anionic surfactants such as linear alkylbenzene sulfonates or alkyl sulfates
[0009] Formulation of several currently commercially available polymers that provide outdoor soil cleaning into granular and liquid laundry detergents, hard surface cleaners, dish cleaning compositions, personal care compositions, and oil drilling compositions for detergent formulators remains a challenge

Embodiment 2

[0057] Example 2: Sorbitol EO of Example 1 114 Amination of hexasulfate

[0058] Weigh sorbitol EO into a 200 mL glass liner 114 Hexasulfate (61.3 g of 90% active, 0.0095 mol) and 3-(dimethylamino)propylamine ("DMAPA" 18.5 g, 0.181 mol). The liner was heated in a swinging autoclave under nitrogen at 152 kPa (150 psig) until the temperature reached 165°C and held at 165°C for 2 hours. Cool to room temperature (20°C to 25°C). The material was extracted with 150 mL of dichloromethane and centrifuged until the salts were separated. The supernatant was transferred to a 500 mL round bottom flask and evaporated using a rotary evaporator at 50 °C until most (less than 5 mL) of the solvent was removed. Excess amine was removed by heating with a Kugelrohr apparatus at 120° C. and 133 Pa (1 mmHg) for 30 minutes to give 47.8 g of a brown hard solid. Proton NMR (500MHz or 300MHz; pulse sequence: s2pul, solvent D 2 O; relaxation delay 0.300 s, pulse 45.0; acquisition time 3.744 s) sho...

Embodiment 3

[0059] Embodiment 3: the quaternization of the amine sulfate of embodiment 2

[0060] In a 500 mL round bottom flask equipped with a magnetic stirring bar, aminated sorbitol EO 114 Dissolve in 100 g of dichloromethane and cool with an ice bath until the temperature reaches 10°C. The solution was adjusted to pH 12 with sodium methoxide (25% in methanol). To the solution was added iodomethane (15.0 g, 0.106 mol). The flask was stoppered and the solution was stirred overnight (approximately 14 hours). The solution was evaporated with a Kugelrohr apparatus at 50°C and 133 Pa (1 mmHg) to give 66 g of a sticky brown solid. Proton NMR (500MHz or 300MHz; pulse sequence: s2pul, solvent D 2 O; relaxation delay 1.000 s, pulse 45.0, acquisition time 2.345 s) shows complete quaternization of nitrogen in all amine capping units.

Abstract

A modified polyol compound having alkoxylation and having at least one anionic capping unit, uses of the modified polyol compound having alkoxylation and having at least one anionic capping unit and cleaning compositions comprising the same.

Description

field of invention [0001] The present invention relates to modified alkoxylated polyol compounds, methods of making modified alkoxylated polyol compounds, and cleaning compositions comprising the same. Background of the invention [0002] Polyol compounds such as sugars such as sucrose or maltose are known to be abundant and readily available raw materials. Ethoxylates of maltitol are known, for example, CAS503446-80-8. This material has been widely disclosed as a surfactant for cosmetic and other personal care applications, as discussed in JP 2003-096182. Other known ethoxylated polyols include: ethoxylated mannitol (CAS 53047-01-2), ethoxylated inositol (CAS 503446-79-5), ethoxylated sorbitol ( CAS 53694-15-8). JP 10-081744 discusses the production of polyether polyols by adding alkylene oxides to sugars in the presence of amine catalysts. However, as "catalyst" implies, an amine catalyst is not incorporated into the structure of the polyether polyol. [0003] Known t...
