Objective

  • In-depth understanding of Laundry detergents:
    • Landscape today’s existing technologies,
    • Predicting the future landscape/trends,
    • Current global scaling strategies and
    • Product to patent mapping

Introduction to Laundry Detergent

  • Laundry detergent means any substance intended for use in laundry washing, based on surfactants and builders, formulated or manufactured to enhance the cleansing action of water. The term includes soaps, bleach as well as powder and liquid synthetic laundry detergents.Laundry detergents
  • A Laundry detergent composition is a formulated mixture of raw materials that can be classified into different types based on their properties and function in the final product.The different classes of raw materials are surfactants, builders, bleaching agents, enzymes, and minors which remove dirt, stain, and soil from surfaces or textiles gave them pleasant feel and odour.
  • Laundry detergent has traditionally been a powdered or granular solid, but the use of liquid laundry detergents has gradually increased over the years, and these days use of liquid detergent equals or even exceeds use of solid detergent.
  • Nowadays laundry detergents are becoming increasingly popular as they can be metered automatically into the washing machine, impart softness, antistaticness, resiliency to fabrics, mild to eyes and skins and shows good dispersibility in water. Because it is consumed when it is used, the sale of laundry detergent is a rather large business. There are many different kinds or brands of laundry detergent sold, many of them claiming some special qualities as selling points.Laundry detergents: an overview

The following picture demonstrates different laundry detergent mechanisms.

  • Soap decreases surface tension of water, making it a better wetting agent.
  • Soap converts greasy and oily dirt into micelles that become dispersed in water.
  • Soap keeps the greasy micelles in suspension and prevents them from redepositing until they can be washed away. (repulsion of the charges)
