Definitions
- the present invention is in the field of cleaning compositions. More particularly, the present invention relates to a concentrated liquid composition premix for providing a liquid detergent on dilution in water.
- Laundry detergent, dishwash detergents, hard surface cleaners are examples of such cleaning compositions.
- Often detergents are available in various formats, such as, powder, bar, liquid, pods etc. Liquid format is one of the formats preferred by consumers.
- a liquid detergent may contain detersive actives, sequestrants, bleaching agents, soil release polymers, enzyme, antifoaming agent etc.
- such detergent contains significant amount of water.
- water acts as carrier for said ingredients and helps in forming a homogenous composition.
- high water content makes the product bulky.
- packaging of the product requires substantial amount of materials, such as, polyethylene, polyethylene terephthalate etc., which are often sourced from non-renewable resources. In this regard there is continuous effort to reduce such consumptions.
- One of the ways to reduce such consumptions is to have a product in liquid concentrated premix or dilutable format.
- a consumer is expected to dilute such product in water to form a liquid detergent and store it in a container.
- Such products are often termed as ‘dilutable’ or ‘dilute at home’ or ‘Do it Yourself’ (abbreviated as ‘DiY’), which implies that consumers prepare their own detergent from a concentrated premix by adding water into in. This differs from in-use dilution, where the consumer doses an aliquot of the detergent into to a bucket of water or in tub of a washing machine forming a ‘wash liquor’ and use it for washing.
- ‘Wash liquor’ is typically low in detersive active content, has viscosity comparable to water and used immediately after preparation.
- ‘dilutable’ or ‘dilute at home’ or ‘DiY’ liquid detergents preferably contain higher amount of detersive actives and has certain product attributes. Viscosity is one of such attributes, which can be correlated to factors, such as, pourability of the product, ease of dissolution of the product when added in water and sensory of the product.
- liquid products in detergent context have certain viscosity significantly higher than water.
- liquid detergent formed on dilution of a ‘dilutable’ or ‘dilute at home’ or ‘DiY’ product or concentrated premix provides a cleaning benefit comparable with conventional liquid detergents available in the market.
- conventional liquid detergents may contain ingredients such as soil release polymer, antifoaming agent, enzyme and preservatives for enhanced cleaning benefits. Often such ingredients are solubilized or disperse homogenously in presence of water providing a stable product.
- a ‘dilutable’ or ‘dilute at home’ or ‘DiY’ or concentrated premix contain significantly low amount or no water. Thus, it is challenging to formulate a stable liquid concentrated premix product with such ingredients.
- liquid detergent formed on dilution of a ‘DiY’ or ‘dilute at home’ product or concentrated premix has viscosity such that a consumer can relate it with conventional liquid detergents available in market, i.e. , viscosity of the liquid detergent should be comparable with conventional liquid detergent available in market,
- compositions comprising oxylakoylated polyglycerol esters, one or more organic solvents and water.

Since the composition premix is a viscous liquid as compared to water, it may take few minutes to from a homogenous liquid. It may be possible to accelerate the dilution process, by stirring the water with an implement, such as, glass rod or by hand. Faster the dilution is better, since consumer may not prefer to wait for long.

- Ex-1 is within the scope of the invention, wherein Ex- A is a comparative example and fall outside the scope of the invention. Ex-1 was a stable formulation, whereas Ex-A did not form a stable formulation.
- stable herein refers to a formulation forming an isotropic, homogenized liquid product. Evaluation of viscosity
- Viscosity of Ex-1 was evaluated in two forms viz. neat and diluted.
- the term ‘neat’ herein refers to the composition used as it is without dilution.
- Ex-1 was diluted with water in 1 :5 ratio by weight.
- Ex-A was not evaluated, since it did not form a stable formulation.
- Viscosity of each sample were measured using Rheocompass (Anton Paar GmbH), at 21S' 1 shear rate and (25 ⁇ 2) °C with CP50 geometry and are summarized below:
- Ex 1 shows viscosity build-up i.e., having higher viscosity on dilution.
