Background and Prior Art
As consumers are moving to lower wash temperatures and seeking products with improved environmental credentials, there is a continuing need to improve the cleaning performance of laundry detergents. One approach to improving the environmental profile of liquid laundry detergents is to add highly weight efficient or multifunctional materials to replace traditional materials such as surfactants, resulting in less overall chemical usage.
One such ingredient is Ethoxylated Polyethyleneimine (EPEI), which is known to improve particulate soil removal from fabrics. However, inclusion of EPEI may reduce the viscosity of the resulting liquid, leading to reduced consumer acceptance, and thus the need to include additional viscosifying techniques.
The present invention solves this problem.

Detailed description and preferred embodiments
Ethoxylated Polyethyleneimine (EPEI)
The Ethoxylated Polyethyleneimine (EPEI) used in the present invention includes in particular a polyethyleneimine formed from recurring- [ (CH)2CH2)N]-a polyethyleneimine backbone consisting of subunits. The backbone is derived from a polyethyleneimine starting material (as defined above) which is ethoxylated to produce EPEI.
More preferably, the average molecular weight (M) of the polyethyleneimine starting material (prior to ethoxylation)w) In the range of 1800 to 2400g/mol, most preferably 1800 to 2200g/mol, such as 1900 to 2100g/mol, by Gel Permeation Chromatography (GPC) with a 1.5% by weight aqueous solution of formic acid as a washThe solution was drained and the determination was carried out using crosslinked polyhydroxyethyl methacrylate as stationary phase (TSKgel GMPWXL column) and by using RI detector and amylopectin standard (PSS GmbH, Mainz, Germany) for calibration.
In the context of the present invention, suitable polyethyleneimine starting materials may be, for example, those conforming to the (empirical) formula- (CH)2-CH2-NH)n-homopolymers of ethyleneimine; wherein n ranges from about 40 to about 120. Preferably, n is from about 40 to about 60.
The shape of the polyethyleneimine starting material may vary, including for example linear, branched, dendritic (hyperbranched) or comb-like structures, depending on the preparation method. The process for preparing such materials is typically an acid catalyzed reaction to open the ring of the ethyleneimine, also known as aziridine.
Examples of suitable polyethyleneimine starting materials for use in the present invention have a branched structure comprising three types of subunits, which may be randomly distributed. The subunits making up the polymer are primary amine units having the formula:
[H2N-CH2CH2]-and-NH2
Which terminates the polymer backbone and any branching chains;
a secondary amine unit having the formula:
-[N(H)CH2CH2]-；
and a tertiary amine unit having the formula:
-[N(B)CH2CH2]-
it is a branch point of the polymer, and B represents a continuation of the chain structure by branching.
The branch may be an ethyleneamino group, e.g. -CH2CH2-NH2A group; or longer radicals, e.g. - (CH)2CH2)-N(CH2CH2NH2)2Or- (CH)2CH2)-N(H)CH2CH2NH2A group. The mixture of primary, secondary and tertiary amine units can each be in any molar ratio, including, for example, a molar ratio of about 1:1:1 to about 1:2: 1. Primary and secondary aminesAnd the molar ratio of tertiary amine units, respectively, may be determined, for example, by13C-NMR or15Determination of N-NMR spectra, preferably at D2And (4) measuring in O. The degree of branching can be defined as follows: DB ═ D + T/D + T + L, where D (dendritic) corresponds to the fraction of tertiary amine units, L (linear) corresponds to the fraction of secondary amine units, and T (terminal) corresponds to the fraction of primary amine units. DB of 0.25-0.95, preferably 0.30-0.80, more preferably 0.5-0.8 is suitable.
In the above-described polyethyleneimine starting materials, each primary or secondary amine hydrogen atom represents a reactive site for subsequent ethoxylation.

The polyethyleneimine starting material may be pretreated (e.g., with a combination of water removal and degassing) prior to the start of the ethoxylation stage.
The standard method for the ethoxylation stage involves reacting the polyethyleneimine starting material with at least sufficient ethylene oxide to provide 2-hydroxyethyl groups per reactive site (i.e., 1 Ethylene Oxide (EO) group per primary or secondary amine hydrogen atom in the polyethyleneimine molecule). The reaction product thus obtained is then condensed with the remaining amount of ethylene oxide, usually in the presence of a basic catalyst.

In a second step (2), the reaction product obtained from step (1), i.e. the partially ethoxylated polyethyleneimine, is reacted with the remaining amount of ethylene oxide in the presence of a basic catalyst. The second step (2) is preferably carried out at a temperature of from 100 ℃ to 250 ℃, more preferably from 120 ℃ to 180 ℃.

Potassium hydroxide is preferred.
The final product obtained is an Ethoxylated Polyethyleneimine (EPEI). The total degree of ethoxylation for each reactive site can be determined according to the following formula: E/(AR), where E is the total moles of ethylene oxide condensed (including hydroxyethylation), a is the moles of polyethyleneimine starting material, and R is the number of reactive sites of polyethyleneimine starting material.

Preferably (w + x + y) ranges from about 40 to about 60. The subunits making up the polymer of formula (I) may be randomly distributed. Typically, w: x: y ranges from about 1:1:1 to about 1:2: 1.

Each of these ingredients will be present in an amount effective to achieve its intended purpose. Typically, these optional ingredients are individually included in amounts up to 5% (by weight based on the total weight of the composition).
Packaging and dosing
The compositions of the present invention may be packaged in unit dose in a polymeric film that is soluble in wash water. Alternatively, the compositions of the present invention may be provided in multi-dose plastic packages having a top or bottom seal. The dosing metering may be provided as part of the lid or as an integrated system with the package.
A method of laundering fabrics using the compositions of the present invention generally comprises diluting a dose of the detergent composition to obtain a wash liquor and laundering the fabrics with the wash liquor so formed. The method of washing fabrics may suitably be carried out in a top-loading or front-loading automatic washing machine, or may be carried out manually.
In automatic washing machines, a dose of detergent composition is typically placed in a dispenser and is flushed from the dispenser into the washing machine by water flowing into the washing machine, thereby forming a wash liquor. The dosage for a typical front loading washing machine (using 10 to 15 litres of water to form wash liquor) may be in the range of about 10ml to about 100ml, preferably about 15 to 75 ml. The dosage for a typical top loading washing machine (using 40 to 60 litres of water to form the wash liquor) may be higher, for example 100ml or more. Lower doses of detergent (e.g. 50ml or less) can be used in the hand wash process (about 1 to 10 litres of water is used to form the wash liquor).
A subsequent water rinsing step and laundry drying are preferred.
The invention will now be further described with reference to the following non-limiting examples.
Examples
All weight percents are by weight based on the total weight of the formulation, unless otherwise specified. Embodiments according to the present invention are indicated by numerals; however, the comparative examples (not according to the invention) are indicated by letters.
