Abstract

The invention relates to a laundry detergent used for washing underwear. The laundry detergent comprises the following components in percentage by weight: 8 to 10 percent of fatty alcohol polyoxyethylene ether sodium sulfate, 1 to 4 percent of propylene glycol, 4 to 10 percent of lauramidopropyl betaine, 0.1 to 1.0 percent of p-chloro-m-xylenol, 1 to 4 percent of cocoanut fatty acid monoethanolamide, 0.1 to 0.5 percent of kathon, 2 to 5 percent of fatty alcohol polyoxyethylene ether, 0.2 to 0.4 percent of essence, 0.0002 to 0.0004 percent of pigment, 0.2 to 0.6 percent of salt and the balance of water; and a proper amount of citric acid is used for adjusting the pH of the laundry detergent to be between 4.0 and 8.5. The phosphorus-free and antibacterial laundry detergent provided by the invention has the advantages of bacteriostasis, decontamination, moderation, fragrance, hard-water resistance, prevention of bacteriological regeneration in cloudy and rainy days and the like, and has the characteristics of simple preparation process, convenient material acquisition, low cost, good economic benefit, suitability for industrial production and wide application prospect.

Background technique [0002] Laundry liquid is a kind of washing product with great market potential. It is characterized by being easily soluble in cold water, saving heat energy, high in surfactant content, and does not have the problem of wet caking. [0003] At present, there are many kinds of liquid detergents, including structural and non-structural types, but most of them contain sodium tripolyphosphate and sodium carbonate, which are relatively alkaline and difficult to wash delicate fabrics. Although some do not contain phosphorus and aluminum, but the formula is simple, the comprehensive washing performance is poor, and the brighteners are mostly derivatives of stilbene triazines, and the fabrics often become dark and yellow after washing.

Problems solved by technology

[0003] At present, there are many kinds of liquid detergents, including structural and non-structural types, but most of them contain sodium tripolyphosphate and sodium carbonate, which are relatively alkaline and difficult to wash delicate fabrics.

Although some do not contain phosphorus and aluminum, but the formula is simple, the comprehensive washing performance is poor, and the brighteners are mostly derivatives of stilbene triazines, and the fabrics often become dark and yellow after washing.

[0004] Therefore, ordinary laundry detergent cannot simultaneously remove a variety of stubborn stains, wash static, and resist hard water.
