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,
