Description

A PREMIX OF CONCENTRATED LIQUID COMPOSITION Field of the invention The present invention relates to cleaning compositions. More particularly, the present invention relates to a premix of concentrated liquid composition for providing a liquid detergent when diluted in water. Background of the invention Consumers prefer to use a variety of cleaning compositions for their household tasks. Laundry detergent, dishwashing detergent, and hard surface cleaners are examples of such cleaning compositions. Detergents are often available in various formats, such as powder, bar, liquid, tablets, etc. The liquid format is one of the most preferred formats by consumers. A liquid detergent may contain detersive active ingredients, sequestrants, bleaching agents, soil-releasing polymers, enzymes, antifoaming agents, etc. In addition, such a detergent contains a significant amount of water. Preferably, water acts as a carrier for these ingredients and helps form a homogeneous composition. However, the high water content makes the product bulky. Therefore, product packaging requires a substantial amount of materials, such as polyethylene, polyethylene terephthalate, etc., which often come from non-renewable resources. In this regard, ongoing efforts are being made to reduce this consumption. 2161476 of 36 One way to reduce this consumption is to offer a product in the form of a concentrated or dilutable liquid premix. The consumer must dilute this product in water to form a liquid detergent and store it in a container. These products are often referred to as dilutable, "home diluted," or "do-it-yourself" (DIY), which implies that consumers prepare their own detergent from a concentrated premix by adding water. This differs from dilution in use, in which the consumer doses an aliquot of the detergent into a bucket of water or a washing machine tub, forming a wash liquor, and uses it for washing. Wash liquor typically has a low active detergent content, a viscosity comparable to that of water, and is used immediately after preparation.On the other hand, dilutable or DIY liquid detergents preferably contain a higher amount of detergent active ingredients and have certain product attributes. Viscosity is one of these attributes, which can be correlated with factors such as the product's pourability, ease of dissolving when added to water, and the product's sensoriality. Typically, liquid products in the context of detergents have a viscosity significantly higher than that of water. The liquid detergent formed by diluting a dilutable or diluted product at home or DIY or a concentrated premix is ​​desired to provide a cleaning benefit comparable to that of conventional commercially available liquid detergents. As mentioned above, conventional liquid detergents may contain ingredients such as soil-releasing polymers, antifoaming agents, enzymes, and 2 2161476 of 36 preservatives to enhance cleaning benefits. These ingredients are often solubilized or homogeneously dispersed in the presence of water, providing a stable product. However, a dilutable or "home-diluted" or "DIY" premix or concentrate contains significantly little or no water. Therefore, it is difficult to formulate a stable concentrated liquid premix product with such ingredients. Furthermore, it is desired that the liquid detergent formed by diluting a DIY or home-diluted product or a concentrated premix, have a viscosity such that a consumer can relate it to conventional liquid detergents available on the market, i.e., the viscosity of the liquid detergent should be comparable to that of conventional liquid detergents available on the market. In this regard, US 2005 / 0112081 (Clariant GmbH, 2005) discloses compositions comprising oxyalkoxylated polyglycerol esters, one or more organic solvents and water. EP 3 714 945 A1 (Applechem Inc., 2018) discloses a liquid thickener composition comprising a polyalkoxylated polyol polyester having Guerbet molecules. The compounds contained therein relate to a polyalkoxylated polyol polyester having a pourable viscosity. WO 2017 / 075681 (Oxiteno SA, 2017) discloses a thickening composition comprising a mixture of one or more alkoxylated polyol esters, one or more ethoxylated sorbitan esters and glycerol, used to increase the viscosity of cosmetic skin cleansing products and 3 2161476 of 36 hair and surface and fabric cleaners, as well as to facilitate the formulation of these products. The thickening composition described is compatible with a wide variety of cosmetic product formulations for skin and hair cleansing and surface and fabric cleaners comprising one or more surfactants, co-surfactants, solvents, fragrances, emulsifiers, preservatives, salts, pigments and / or coloring agents, in addition to other compounds inert with respect to the final performance, this composition being capable of increasing their viscosity in a stable and measurable manner. WO2012 / 082097 A1 (Colgate-Palmolive Co, 2012) discloses a self-preserving, acidic, aqueous liquid cleaning composition, typically a dishwashing liquid, having a pH for the composition within the range of 2.5 to 5 initially and upon dilution, which composition comprises a plurality of surfactants, wherein the surfactants include surface active components comprising from greater than 39% up to 55% by weight, based on the weight of the composition, wherein the composition has a viscosity of 80 to 3000 mPa.s measured at 25°C, and the composition is dilutable with water to form a diluted, non-gelling composition having up to five times the volume of the undiluted composition and a viscosity within the range of 80 to 3000 mPa.s measured at 25°C at any dilution up to a five-fold dilution. Despite the prior art documents, there remains a need for an improved concentrated liquid composition premix that provides a liquid detergent upon dilution in water, wherein the liquid detergent 2161476 of 36 has one or more attributes similar to conventional liquid detergents available on the market. The present inventors surprisingly discovered that an alkoxylated polyol polyester-based associative polymer and an anionic surfactant with an ammonia counterion provide a premix with a stable and isotropic composition. The premix provides a liquid detergent when diluted in water, which has a viscosity comparable to or greater than the premix and is similar to conventional liquid detergents.

Examples The formulations were prepared following the recipe provided in Table 1: Table 1: Materials (% w / w) Ex-A Ex-1 Linear alkyl benzenesulfonic acid — 29.6 Monoethanolamine — 6.1 2161476 of 36 Sodium linear alkyl benzenesulfonate 35.7 - Lauryl ether sulfate with monoisopropanolamine - 19.0 Sodium laureth sulfate 19.0 Ethoxylated alcohol (EO7) 23.6 23.6 Monopropylene glycol Up to 100 Up to 100 Heptanol 5.0 5.0 Sorbithix L-100 5.0 5.0 Sequestrant 6.2 6.2 Perfume 1.5 1.5 Unstable Stable Ex-1 is within the scope of the invention, while Ex-A is a comparative example and falls outside the scope of the invention. Ex-1 was a stable formulation, while Ex-A did not form a stable formulation. The term "stable" refers here to a formulation that forms an isotropic, homogenized liquid product. Viscosity evaluation The viscosity of Ex-1 was evaluated in two forms: neat and diluted. The term neat refers here to the composition used as is, undiluted. In the diluted form, Ex-1 was diluted with water in a 1:5 weight ratio. Ex-A was not evaluated because it did not form a stable formulation. 2161476 of 36 The viscosity of each sample was measured using Rheocompass (Anton Paar GmbH), at a shear rate of 21S-1y (25 ± 2) °C with CP50 geometry and is summarized below: Table 2: Ex-1 Viscosity and purity 380 Viscosity 1:5 dilution to 21 S-1 850 According to Table 2, Ex-1 shows an increase in viscosity, that is, it has higher viscosity in the dilution.
