[0080] E) Preparation of detergent composition

[0081] The detergent compositions of the present invention may be in liquid, paste or granular form. Such compositions may be prepared by admixing the essential and optional ingredients in the desired concentrations, in any suitable order and by any conventional method.

[0082] Granular compositions are typically prepared, for example, by mixing the basic granular components such as surfactants, builders, water, etc. into a slurry and spray drying the resulting slurry to a low level of residual moisture (5-12%). , the remaining dry ingredients, such as the necessary cyclic amine-based fabric treatment material granules, can be mixed in the form of a granulated powder with the spray-dried granules in a rotating mixing drum. Solutions of liquid components, such as the necessary cyclic amine-based fabric treatment materials, enzymes, binders and perfumes, can be sprayed onto the prepared granules to form the final detergent compo...

Embodiment 1

[0105] A solution of 92.6 g (1.36 mol) of imidazole in 140.5 g of water was heated to 50° C. and mixed within 10 minutes with an aqueous solution of 8.2 g (0.07 mol) of 2-chloroacetic acid sodium salt in 50 g of water. The solution was then heated at 65°C until all of the 2-chloroacetic acid sodium salt had reacted, as determined by analysis of the chloride ion content of the solution. Add 5.6 g (0.07 mol) of 50% (weight) concentration of sodium hydroxide aqueous solution and add 89.7 g (0.97 mol) of epichlorohydrin within 30 minutes while stirring so that the temperature of the reaction mixture can be maintained at 55-65 ℃. After the addition of epichlorohydrin, the reaction mixture was heated to 80° C. and stirred at this temperature for 4 hours. Afterwards, no alkylating agent was detectable. 377.7 g of a yellowish aqueous solution of an amphoteric amine-based polymer having a net cationic charge of 4.2 meq / g polymer was obtained. The solution had a pH of 6.97 and contai...

Embodiment 2

[0107] According to the step given in Example 1, 92.6g (1.36 moles) of imidazole, 16.3g (0.14 moles) of sodium chloroacetate, 11.2g (0.14 moles) of 50% (weight) concentration of sodium hydroxide aqueous solution and 86.1 g (0.93 moles) of epichlorohydrin was reacted. 386.3 g of a yellowish aqueous solution of an amphoteric amine-based polymer having a net cationic charge of 3.4 meq / g polymer was obtained. The solution had a pH of 7.10 and contained 49.6% water, 0.1% glycolic acid and less than 0.05% 2-chloroacetic acid. The molecular weight of the polymer is Mn=650, Mw=1320, and Mw / Mn=2.0.

Abstract

Detergent compositions and fabric conditioning compositions which utilize certain oxidized cyclic amine based polymer, oligomer or copolymer materials of general formula (I), wherein W comprises at least one cyclic constituent selected from the group consisting of (a), (b) and (c). In addition to the at least one cyclic constituent, W may also comprise an aliphatic or substituted aliphatic moiety of general structure C5-C20alkyl, C5-C7cycloalkyl, C7-C20alkylaryl, C7-C20. In these general structures at least about 10 mole %, of the R3 groups are O, provided that O is only present on a tertiary N. These oxidized cyclic amine based polymer, oligomer or copolymer materials serve as fabric treatment agents that can impart fabric appearance and integrity benefits to fabrics and textiles laundered in washing solutions which contain such materials.

Description

field of invention [0001] The present invention relates to compositions for use in laundry applications in liquid or granular form, wherein the compositions comprise certain anionically modified cyclic amine based polymeric, oligomeric or copolymeric materials which are given in the form of such Fabrics and textiles laundered in wash solutions formed from the compositions impart appearance and integrity. Background of the invention [0002] Of course, it is well known that the cycle of use and laundering of fabrics and textiles, such as used clothes and clothing items, inevitably has a detrimental effect on the appearance and integrity of the used and laundered fabrics and textiles. Fabrics and textiles simply wear out over time and use. Fabrics and textiles need to be laundered to remove soil and stains that have accumulated in and on them during ordinary use. However, the laundering operation itself over many cycles can aggravate and contribute to...
