Aqueous liquid cleaning agent composition for household or industrial use, containing a self-inverse latex with the acrylamide monomer containing polygycerol esters, and its use as a thickening agent in a washing or cleaning mixture.

Description

[0001] The invention relates to liquid aqueous detergent compositions (F) for household or industrial use comprising self-inverting inverse latexes comprising, as reversing agent, a surfactant composition comprising polyglycerol esters and glycerol and / or glycerol oligomers, the use of said self-inverting inverse latexes as thickeners used to prepare detergent or cleaning formulations for industrial or household use, as well as these formulations.

[0002] These detergent or cleaning formulations for industrial or household use are either alkaline or acidic. Alkaline formulations are generally used to remove grease stains from hard surfaces, while acidic formulations are used not only to remove dirt, but also to descale said surfaces. They are particularly suitable for cleaning and descaling installations in the food industry, or for descaling household appliances, such as dishwashers and coffee machines. They are also used to remove concrete or cement residues, and for cleaning grease present deep on concrete surfaces before any painting operation on said concrete surfaces.Acid detergent formulations must not cause significant foaming during the cleaning operation in the presence of the soiling to be treated, they must have good wetting and detergent properties. Detergent or cleaning formulations for industrial or household use are in the form of powders, concentrates, liquids such as emulsions, and depending on the case, are used directly or after dilution in a suitable solvent. In liquid form, such as emulsions, they include rheology modifiers during their manufacture.

[0003] These rheology modifiers are preferably thickening and / or gelling agents which are intended to thicken the aqueous phase or the emulsion comprising the detergent surfactants, so as to allow the user to control the flow thereof, for example by means of a circulation pump, and also to be able to suspend and / or stabilize solid particles. Among the rheology modifiers which can be used for the preparation of detergent or cleaning formulations for industrial or household use, mention may be made of synthetic polymers such as, for example, anionic, or cationic, or ampholyte polyelectrolytes, linear or branched, crosslinked or non-crosslinked, which are in two physical forms, powder form and liquid form.

[0004] The international application published under number WO 2016 / 020622 A1 describes the use, for the manufacture of a liquid aqueous detergent composition for household or industrial use, of a branched or crosslinked polymer obtained by polymerization of an aqueous solution of one or more monomers in inverse emulsion of the water-in-oil type, with at least one of the monomers used being an acrylic monomer and one or more of the monomers used being a monomer carrying at least one weak acid function, the molar percentage of monomers carrying at least one weak acid function relative to all the monomers used being at least 30%.

[0005] In the processes for preparing self-invertible inverse latexes by implementing radical inverse emulsion polymerization, the oil-in-water surfactants are added at the end of the polymerization step. Their addition is intended to modify and adjust the hydrophilic-lipophilic balance of the water-in-oil emulsion comprising the polymer (also called "inverse latex") so as to obtain a mixture which, once added to a polar phase such as water, will change the direction of emulsion to pass from the water-in-oil form to the oil-in-water form, thus making it possible to bring the previously prepared polymer into contact with the polar phase to be thickened. During such a physical phenomenon, the crosslinked and / or branched polyelectrolyte polymer unfolds in said polar phase and forms a three-dimensional network allowing the polar phase to swell, which is manifested by an increase in the viscosity of this polar phase.

[0006] The mixture comprising the "invert latex" and the oil-in-water surfactant is called a self-inverting inverse latex and said oil-in-water surfactant is called an "inverter" or "inverting agent".

[0007] The reversing agents commonly used for the preparation of self-reversing inverse latexes are oil-in-water surfactants that have a sufficiently high HLB (Hydrophilic Lipophilic Balance) value to allow the preparation of stable oil-in-water emulsions, generally greater than 9 and less than 16. They generally comprise a hydrophilic part consisting of a chain of ethylene oxide units and a part consisting of an aliphatic hydrocarbon chain of a hydrophobic nature. Among these reversing agents, there are: Ethoxylated fatty alcohols, whose aliphatic hydrocarbon chain contains 8 to 14 carbon atoms and whose number of ethylene oxide units is between 5 and 40, for example ethoxylated lauryl alcohol with 7 moles of ethylene oxide (INCI name: Laureth-7), or tridecyl alcohol with 6 moles of ethylene oxide (INCI name: trideceth-6); Ethoxylated sorbitan esters, the aliphatic hydrocarbon chain of which has from 12 to 22 carbon atoms and the number of ethylene oxide units of which is between 5 and 40, for example ethoxylated sorbitan oleate containing 20 moles of ethylene oxide sold under the trade name Montanox ™< 80, or ethoxylated sorbitan laurate containing 20 moles of ethylene oxide sold under the trade name Montanox ™< 20; Ethoxylated alkylphenols, for example ethoxylated nonylphenols and ethoxylated octylphenols;or Ethoxylated castor oils, for example, ethoxylated castor oil with 40 moles of ethylene oxide marketed under the brand name SIMULSOL ™ < OL 50. ;

[0008] Changing consumer demands and regulatory requirements are leading cosmetic formulators to reduce the proportion of ingredients containing ethylene oxide units in their formulations. There is therefore a need to prepare self-inverting inverse latexes free from ethoxylated surfactants as inverting agents.

[0009] French patent applications published under numbers 2,794,034, 2,794,124, 2,808,447, 2,808,446 and 2,810,883 describe the use of alkyl polyglycosides, the hydrocarbon alkyl chain of which contains from one to thirty carbon atoms, as inverting agents for preparing self-inverting inverse latexes, such as, for example, mixtures of alkyl polyglucosides the hydrocarbon alkyl chains of which are decyl, dodecyl and tetradecyl chains such as the mixture marketed under the brand name SIMULSOL ™< SL 10, dodecyl, tetradecyl and hexadecyl chains such as the mixture marketed under the brand name SIMULSOL ™< SL 26, octyl and decyl chains such as the mixture marketed under the brand name SIMULSOL ™< SL 8, or the undecylenyl chain such as the mixture marketed under the brand name SIMULSOL ™< SL 11W.

[0010] However, the use of such compounds to prepare self-inverting inverse latexes must be carried out at a temperature above their melting point, generally at 70°C, which poses problems of increasing the viscosity of the inverse latex and leads to a certain destabilization of said prepared self-inverting inverse latex. In certain cases, it is carried out by previously diluting said alkyl polyglycosides in water to have a liquid form that can be handled at room temperature. This sometimes has the consequence of reducing the inversion speed of said self-inverting inverse latexes in the polar phases to be thickened, and therefore of reducing the productivity of the processes for preparing cosmetic formulations comprising such thickening agents.

[0011] The international application published under number WO 2009 / 156691 discloses the use of polyglycerol esters as inverting agents for preparing self-inverting inverse latexes, for example decaglycerol esters such as decaglycerol monolaurate, decaglycerol oleate, decaglycerol monocaprylate or decaglycerol monomyristate. However, their use leads to self-inverting inverse latexes for which the inversion rate in the polar phases to be thickened is too slow and even decreases when the self-inverting inverse latex is stored after its preparation for more than one month of preparation.

[0012] The inventors therefore sought to develop a new oil-in-water type reversing surfactant system, compatible with current environmental standards, in particular by being free of alkylene oxide units which make it possible to prepare self-reversing inverse latexes: which can be easily used and in particular which can be pumped at 25°C, which have a viscosity less than or equal to 8,000 mPa.s, preferably less than or equal to 5,000 mPa.s, viscosity measured at 25°C using a Brookfield RVT viscometer and spindle No. 3 at a speed of 20 revolutions / minute, which have a smooth appearance, free of grains or lumps, and which have good inversion properties in polar phases, i.e. inducing a rapid and reliable inversion speed.

[0013] The invention, as defined in the claims, therefore relates to a liquid aqueous detergent composition (F) for household or industrial use comprising as thickening agent, for 100% of its total mass between 0.1% and 10% by mass, a self-invertible inverse latex of a crosslinked anionic polyelectrolyte (P) comprising, for 100 mol%: (a 1 ) - of a proportion greater than or equal to 25 mol% and less than or equal to 80 mol%, of monomeric units derived from 2-methyl 2-[(1-oxo 2-propenyl) amino] 1-propanesulfonic acid in free acid form or partially or totally salified; (a 2 ) - of a proportion greater than or equal to 20 mol% and less than or equal to 75 mol%, of monomeric units derived from at least one monomer chosen from the elements of the group consisting of acrylamide, N,N-dimethyl acrylamide; methacrylamide or N-isopropyl acrylamide;(a 3 ) - optionally of a proportion greater than 0 mol% and less than or equal to 10 mol%, of monomeric units derived from at least one monomer chosen from the elements of the group consisting of acrylic acid, methacrylic acid, 2-carboxyethyl acrylic acid, itaconic acid, maleic acid, 3-methyl 3-[(1-oxo 2-propenyl) amino] butanoic acid, the carboxylic function of said monomers being in free acid form, partially salified or totally salified; (a 4 ) - of a proportion greater than 0 mol% and less than or equal to 1 mol% of monomeric units derived from at least one diethylenic or polyethylene crosslinking (AR) monomer; the sum of said molar proportions in monomeric units according to a 1 ), a 2 ) a 3 ) and a 4 ) being equal to 100% mol; ; said self-inverting inverse latex being a water-in-oil type emulsion (E) comprising for 100% of its mass: a)- from 10% by mass to 90% by mass of said crosslinked anionic polyelectrolyte (P); b) - From 5% by mass to 50% by mass, of a fatty phase consisting of at least one oil (H), c) - From 1% by mass to 50% by mass of water, d) - From 0.5% by mass to 10% by mass of a water-in-oil type emulsifying system (S 1 ), and e) - From 2% by mass to 10% by mass of an oil-in-water type emulsifying system (S 2 ); the sum of the mass proportions of compounds according to a), b), c), d) and e) being equal to 100% by mass; said oil-in-water type emulsifying system (S 2 ) of the self-invertible inverse latex comprising for 100% of its mass: f) - A proportion greater than or equal to 50% by mass and less than or equal to 100% of a composition (Ce) which comprises for 100% of its mass: e 1 )- From 10% by mass to 60% by mass of at least one compound of formula (I): HO-[CH 2 -CH(OH)-CH 2 -O] n -H (I) in which n represents an integer greater than or equal to one and less than or equal to fifteen; e 2 ) - From 40% by mass to 90% by mass of at least one compound of formula (II): R 1 -(C=O)-[O-CH 2 -CH(OH)-CH 2 ] p -OH (II), in which p, different or identical to n, represents an integer greater than or equal to one and less than or equal to fifteen; and in which the group R 1 -(C=O)- represents a saturated or unsaturated, linear or branched aliphatic radical, comprising from six to twenty-two carbon atoms, and optionally e 3 )- Up to 30% by mass of at least one composition (C 11 ) represented by the formula (III): HO-[CH 2 -CHOH-CH 2 -O-] q -(G) r -H (III), in which q, different from or identical to n, represents an integer greater than or equal to one and less than or equal to 3, G represents the remainder of a reducing sugar and r represents a decimal number greater than or equal to 1.05 and less than or equal to 5.00, said composition (C 11 ) consisting of a mixture of the compounds of formulae (III 1 ), (III 2 ), (III 3 ), (III 4 ) and (III 5 ): HO-[CH 2 -CHOH-CH 2 -O-] q -O-(G) 1 -H (III 1 ), HO-[CH 2 -CHOH-CH 2 -O-] q -O-(G) 2 -H (III 2 ), HO-[CH 2 -CHOH-CH 2 -O-] q -O-(G) 3 -H (III 3 ), HO-[CH 2 -CHOH-CH 2 -O-] q -O-(G) 4 -H (III 4 ), HO-[CH 2 -CHOH-CH 2 -O-] q -O-(G) 5 -H (III 5 ), in molar proportions of said compounds of formulae (III 1 ), (III 2 ), (III 3 ), (III 4 ) and (III 5 ) respectively equal to a 1 , a 2 , a 3 , a 4 and a 5 ,such that the sum (a 1 + a 2 + a 3 + a 4 + a 5 ) is equal to one, and that the sum (a 1 + 2a 2 + 3a 3 + 4a 4 + 5a 5 ) is equal to r; the sum of the mass proportions in compounds according to e 1 ), e 2 ) and e 3 ) being equal to 100% by mass.

Table 1 Emulsifying composition (EM 1) (EM 2) (EM 3) Proportions of constituents (% by mass) Decaglycerol monolaurate 100% 71,5% 71,5% Mass proportion of hexaglycerol 0% 28,5 0% Mass proportion of decaglycerol 0% 0% 28,5 II- Preparation and evaluation of self-inverting inverse latexes of a crosslinked terpolymer of the sodium salt of 2-methyl-[(1-oxo-2-propenyl)amino] 1-propanesulfonic acid of acrylamide and partially salified acrylic acid and of a self-inverting inverse latex of a crosslinked copolymer of the sodium salt of 2-methyl-[(1-oxo-2-propenyl)amino] 1-propanesulfonic acid and acrylamide.

[0097] II-a) - An aqueous phase is prepared by successively pouring into a beaker and with stirring 277 grams of a commercial solution at 50% by mass of acrylamide, 375 grams of a 55% aqueous solution of sodium salt of 2-methyl-[(1-oxo-2-propenyl)amino] 1-propanesulfonic acid, 10.8 grams of glacial acrylic acid, 0.058 grams of methylene bis(acrylamide), 0.45 grams of a commercial aqueous solution at 40% by mass of sodium diethylenetriamine pentaacetate, and 5.3 grams of a 48% by mass aqueous solution of sodium hydroxide to adjust the pH of this aqueous phase to 5.3.

[0098] An organic phase is prepared independently by mixing 130 grams of polyisobutene, 90 grams of Isopar ™< H, 30 grams of Marcol ™< 52, 17.0 grams of Montane ™< 70, 5 grams of Simaline ™< IE 200 and 0.2 grams of azo bis(isobutyronitryl) (AIBN).

[0099] The prepared aqueous phase is then gradually added to the oily phase and then dispersed using an Ultra Turrax type rotor stator marketed by the company Ika.

[0100] The resulting emulsion is transferred to a reactor to be subjected to nitrogen bubbling to eliminate oxygen and cooled to approximately 5-6 °C. 5 cm 3 of a 0.42% by mass solution of cumene hydroperoxide in ISOPAR ™ H is added to the emulsion while stirring, then a 0.1% by mass aqueous solution of sodium metabisulfite is gradually introduced at a flow rate of 0.5 cm 3 per minute to initiate the polymerization reaction. The temperature of the medium increases until it reaches a plateau.

[0101] After maintaining at 80°C for one hour, the Isopar ™< H is removed from the reaction medium by distillation under partial vacuum, as well as a major part of the water. The reaction medium is then cooled to approximately 35°C to obtain the mixture noted (M 1 ).

[0102] The mixture (M 1 ) previously obtained is divided into different portions to which are added the different surfactant compositions (EM 1 ), (EM 2 ) and (EM 3 ), as described above, previously heated to 60°C, in mass proportions as indicated in table 2 below.

[0103] The self-inverting inverse latexes resulting from these mixtures are respectively noted (LI 1 ), (LI 2 ), and (LI 3 ) are evaluated by observing their appearance at 25°C, by the inversion speed during the preparation of an aqueous gel at 2% by mass of self-inverting inverse latex (the method of which is described below), by the viscosity of this aqueous gel at 2% by mass of a self-inverting inverse latex.

[0104] The method for evaluating the inversion time of self-inverting inverse latexes consists of introducing into a 2-liter beaker the quantity of water necessary for the preparation of an 800-gram aqueous gel. A mechanical stirrer propeller of the Turbotest ™ type, version 2004, marketed by the company VMI, connected to a motor, is placed towards the bottom of the beaker. Stirring is started at a speed of 900 rpm and the necessary quantity of self-inverting inverse latex to be evaluated is introduced into the beaker while stirring. Stirring creates a vortex which disappears when the polymer inverts and the gel forms. The inversion time, measured in seconds, of self-inverting inverse latexes corresponds to the time elapsed between the start of the addition of the self-inverting inverse latex tested and the disappearance of the vortex, leading to the production of a smooth, lump-free gel.This evaluation is carried out at the end of the manufacturing of the tested inverse latexes (t = 0), then after a storage period of 2 months at 25°C (t = 2 months). The results obtained are recorded in Table 2 below. The viscosity of an aqueous gel at 2% by mass of self-inverting inverse latex (µ), is measured at t = 0 then at t = 2 months, using a Brookfield RVT viscometer (Mobile 6 Speed ​​5). Similarly, the appearance of the self-inverting inverse latex is visually evaluated at t = 0.

[0105] The self-inverting inverse latexes (LI 2 ) and (LI 3 ) according to the invention, and free from alkoxylated derivatives, make it possible to obtain smooth gels, with an inversion time much lower than that observed for the self-inverting inverse latex (LI 1 ), comprising only decaglycerol monolaurate as a constituent of the inverting surfactant system, while retaining excellent thickening properties. In addition, they are characterized by better reproducibility of the inversion speed and thickening properties after two months of storage than for the comparative self-inverting inverse latex (LI 1 ). III- Preparation and evaluation of self-invertible inverse latexes of a crosslinked copolymer of the sodium salt of 2-methyl-[(1-oxo-2-propenyl)amino] 1-propanesulfonic acid and acrylamide.

[0106] An aqueous phase is prepared by successively pouring into a beaker and with stirring 255 grams of a commercial solution at 50% by mass of acrylamide, 272 grams of a 55% aqueous solution of sodium salt of 2-methyl-[(1-oxo-2-propenyl)amino] 1-propanesulfonic acid, 0.107 grams of methylene bis(acrylamide), 0.45 grams of a commercial aqueous solution at 40% by mass of sodium diethylenetriamine pentaacetate, and 45 grams of a 48% by mass aqueous solution of sodium hydroxide to adjust the pH of this aqueous phase to 6.0.

[0107] An organic phase is prepared independently by mixing 220 grams of Emogreen ™< L15 and 25 grams of Simaline ™< IE.

[0108] The prepared aqueous phase is then gradually added to the oily phase and then dispersed using an Ultra Turrax type rotor stator marketed by the company Ika.

[0109] The resulting emulsion is transferred to a reactor to be subjected to nitrogen bubbling to eliminate oxygen and cooled to approximately 5-6 °C. 0.69 grams of sodium persulfate previously dissolved in 2 grams of water is added to the emulsion, which is kept stirring, then a 2.25% aqueous solution by mass of sodium metabisulfite is gradually introduced to initiate the polymerization reaction. The temperature of the medium increases until it reaches a plateau.

[0110] After maintaining it at 80°C for three hours, the reaction medium is then cooled to approximately 35°C to obtain the mixture noted (M 2 ).

[0111] The mixture (M 2 ) previously obtained is divided into different portions to which the different surfactant compositions (EM 1 ), (EM 2 ) and (EM 3 ) are added, as described above, previously heated to 60°C, in mass proportions as indicated in table 3 below.

[0112] The self-inverting inverse latexes resulting from these mixtures are respectively noted (LI 4 ), (LI 5 ) and (LI 6 ) are evaluated by observing their appearance at 25°C, by the speed of inversion during the preparation of an aqueous gel at 2% by mass of self-inverting inverse latex (the method of which is described below), by the viscosity of this aqueous gel at 2% by mass of a self-inverting inverse latex.

[0113] The method for evaluating the inversion time of self-inverting inverse latexes consists of introducing into a 2-liter beaker the quantity of water necessary for the preparation of an 800-gram aqueous gel. A mechanical stirrer propeller of the Turbotest ™ type, version 2004, marketed by the company VMI, connected to a motor, is placed towards the bottom of the beaker.

This evaluation is carried out after the manufacture of the tested inverse latexes (t = 0).The results obtained are recorded in Table 3 below. The viscosity of a 2% by mass aqueous gel of self-inverting inverse latex (µ), is measured at t = 0 using a Brookfield RVT viscometer (Mobile 6 Speed ​​5). Similarly, the appearance of the self-inverting inverse latex is visually evaluated at t = 0.

[0114] The self-inverting inverse latexes (LI 5 ) and (LI 6 ) according to the invention, and free from alkoxylated derivatives, make it possible to obtain at t = 0, smooth gels, with an inversion time shorter than that observed for the self-inverting inverse latex (LI 1 ), comprising only decaglycerol monolaurate as a constituent of the inverting surfactant system, while retaining excellent thickening properties.
