Description

Technical Field

[0001] The present invention relates to a stable detergent composition containing a biodegradable thickener. Specifically, the present invention relates to a detergent composition containing water, a surfactant, and a biodegradable thickener containing starch and cellulose. Such a composition surprisingly provides excellent foaming and viscosity characteristics, is easy to rinse, clean, and has a non-film feel, has a low amount of surfactant, and is formulated without substantially containing synthetic thickeners such as soap, sulfate, isethionate, and / or ammonium acryloyldimethyltaurate vinyl pyrrolidone copolymer, alkyl acrylate crosspolymer, etc., and has no bleeding, discoloration, and bad odor after storage at high temperature.

Background Art

[0002] Detergent compositions are typically used to clean surfaces such as the skin and are often used to reduce the shine associated with sebum produced by specialized epithelial cells known as sebaceous glands. It is also used to reduce surface bacteria such as on the hands and face, and thus washing is considered the most effective way to prevent the spread of bacteria and germs. In fact, experts believe that regular washing throughout the day can reduce the number of consumers getting colds by about 50%.

[0003] Consumers generally know that it is a good habit to wash their hands regularly and avoid touching their faces, eyes, and mouths in order to minimize the risk of getting sick. According to information provided by the Centers for Disease Control and Prevention, the COVID-19 (coronavirus) pandemic is a direct result of a virus that is more efficient and severe than the flu and spreads rapidly from person to person via respiratory droplets. During such a pandemic, consumers understand and medical experts emphasize that it is best for everyone to always wash their hands and the inanimate surfaces they come into contact with before use.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Consumers have become more frequent in cleaning, so there is a strong desire to develop a detergent composition that is not only good for consumers, enjoyable to use, but also more environmentally friendly. Therefore, the present invention relates to a stable detergent composition containing water, a surfactant, and a biodegradable thickener containing starch and cellulose. Surprisingly, the detergent composition provides excellent foaming and viscosity characteristics, is easy to rinse, gives a clean and film-free feel, contains a small amount of surfactant, and is formulated without substantially containing synthetic thickeners such as soap, sulfate, isethionate, and ammonium acryloyldimethyltaurate vinylpyrrolidone copolymer, alkyl acrylate crosspolymer, and does not show bleeding, discoloration, or bad odor even after storage at high temperature.

[0005] Additional Information An effort for manufacturing a detergent composition is disclosed. US Patent Application No. 2019 / 008738A1 describes a personal care composition containing a cationic surfactant, a nonionic surfactant, and a polyacrylate crosspolymer structuring agent. The detergent composition can contain carrageenan as a thickener.

[0006] Other efforts for manufacturing a detergent composition have been reported. US Patent Application No. 2019 / 0359735A1 describes a water-soluble hybrid polymer suitable for use in body wash.

[0007] Still other efforts regarding the manufacture of a detergent composition are also described. US Patent No. 9,549,885 describes a scalp care composition that can contain a synthetic rheology modifier such as an acrylamide / ammonium acrylate / C10-C30 alkyl acrylate crosslinked polymer or an acrylate / steareth-20 itaconate copolymer.
