Definitions
- the present invention is in the field of cleaning compositions.
- it relates to a concentrated liquid cleaning composition for providing a liquid detergent on dilution in water.
- a cleaning composition in liquid format may contain detersive actives, sequestrants, bleaching agent, anti-foaming agent, enzyme, preservatives etc. Apart from these, it also contains significant amount of water. Preferably, water acts as carrier for said ingredients and helps in forming a homogenous composition. It also helps in providing a rheology suitable for dosing and applying the composition easily on the surfaces to be cleaned. However, high water content makes the product bulky. Thus, packaging of the product requires substantial amount of materials, such as, polyethylene, polyethylene terephthalate etc. The packaging materials are often sourced from non-renewable resources. In this regard there are continuous efforts to reduce such consumptions.
- One of the ways to reduce such consumptions is to have a product in concentrated 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 ‘Do it Yourself’ or abbreviated as ‘DiY’, which implies that a consumer prepare their own detergent from a precursor/concentrate by diluting it in water.
- the consumer doses an aliquot of the liquid detergent into to a bucket/bowl of water or in tub of a washing machine forming a wash liquor and use it for washing.
- same product may be available in three forms, namely, concentrate, liquid detergent and wash liquor depending on extent of dilution. Typically, they vary in detersive content.
- wash liquor typically lowest in detersive active content among the forms has viscosity like water and used immediately after preparation.
- liquid detergent has attributes, such as, efficacy, appearance, sensory, stability etc., and they are supposed to be stored in a container for later use. It is expected that those attributes are such that consumers may relates the liquid detergent to conventional liquid detergents available in market.
- Viscosity of liquid products is one of the key attributes. It can be correlated to pourability of the product. It also often relates to sensory of the product. For example, consumers relate high viscosity to high amount of detersive agent in the product, which drives manufactures to provide liquid detergents in viscous form. Thus, it is desired that the liquid detergent formed on dilution of a ‘DiY’ product has viscosity such that a consumer can relate it with conventional liquid detergents available in market.
