Description

The present invention relates to a liquid detergent composition. More particularly, the present invention relates to a liquid detergent composition having excellent dispersion stability against particles, bubbles, and the like, and excellent in removing water and oil from oil, and removing odor from clothes and tableware.

In general, in order to differentiate the formulation of the liquid detergent and to enhance cleaning power, skin moisturizing power, and the like, granules impregnated with abrasive particles or active ingredients or microbubbles are often dispersed. In this case, in order to maintain the dispersion stability of the product for a long time, a thickener such as an acrylic acid-based synthetic polymer, or a colloidal silica, gum or cellulose natural thickeners have been used.

In general, however, acrylic polymer thickeners have a disadvantage in that the cost of liquid detergents increases, and when a polymer that is difficult to dissolve in water is applied, a premixer step is required to be solubilized in water using a homomixer. There is a disadvantage. Xanthan gum and cellulose are more economical than acrylic polymer thickeners, but require a heating process to solubilize in water, and have weaknesses in phase stability under acid, alkali, low temperature, and high temperature conditions. Some raw materials have greatly improved water solubility by supplementing these shortcomings of acrylic acid, gum and cellulose thickeners recently. However, they are economically expensive when applying products, and even if the viscosity is increased by the addition of thickeners, these raw materials have a positive effect on the cleaning power. It has a disadvantage of not slippery or easy to dissolve in water.
