Description

An amino acid adult laundry liquid

Technical field

The invention relates to an adult laundry liquid, and more particularly to an amino acid adult laundry liquid which is a safe and environmentally friendly amino acid surfactant, and belongs to the field of consumer goods for daily use.

Background technique

With the integration of the world economy and the development of trade globalization, cultural background, technical level and environmental protection regulations have gradually become the three driving forces for the global development of detergents. The global detergent products will tend to be diversified, but energy-saving, water-saving, Products that are efficient, gentle, easy to use, and meet safety and environmental requirements will be the mainstream of current and future laundry product development. Since the laundry liquid overcomes some of the shortcomings of the washing powder, it has developed rapidly. As we all know, the washing powder contains a large amount of filler powder without any washing effect, and its mass fraction is more than 40%, which causes great waste in resources and energy, and also causes dust pollution in production, which is not conducive to environmental protection. . The laundry liquid replaces the Yuanming powder with abundant and inexpensive water, and is made up of a biodegradable surfactant as a main component and supplemented with a phosphorus-free additive. Due to the low investment in equipment, simple production process, mild and non-irritating properties, easy to dissolve and easy to use, it is gradually accepted by people.

However, as an emerging promising liquid product, it also has its shortcomings. The active ingredient of the existing laundry liquid is mainly a surfactant, which is mainly composed of a chemically synthesized surfactant such as sodium lauryl sulfate. However, it is not easily degraded or degraded, causing pollution to the environment. With the gradual enhancement of people's awareness of environmental protection, the future development direction of laundry liquid will be based on environmentally friendly green type. In addition to strong decontamination, harmless to the human body, sterilization, mild and high foaming, it should also be easily degraded and not pollute the environment.

In recent years, with the deepening of amino acid research, amino acids have been increasingly used in various fields. Among them, the application of amino acids in daily chemicals is also a subject worthy of study, and amino acid daily chemicals have been accepted and sought after by more and more people. In the daily chemical industry, amino acid daily chemicals are undoubtedly one of the highlights, which has injected new vitality into the Japanese chemical industry.

Amino acids are a general term for a class of organic compounds containing amino and carboxyl groups. It is the most basic substance that constitutes a biological protein and is related to life activities. It is the basic unit that constitutes a protein molecule in a living body and has a close relationship with the life activities of a living being. It has special physiological functions in antibodies and is one of the indispensable nutrients in the body.

Preferably, the alanine type surfactant comprises at least one of sodium N-lauroyl-L-alaninate and sodium cocamidopropionate in a concentration of 98% or more.

Compared with the prior art, the present invention has at least the following advantages:

The amino acid adult laundry liquid of the invention has the following advantages: 1. The amino acid surfactant is used as the main active ingredient, instead of the traditional laundry liquid surfactant, such as sodium lauryl sulfate; the chemical detergent residue is removed from the human body. Injury and environmental pollution, and no stimulation, no allergies, close-fitting clothing and baby clothes are suitable for use; 2, low foam easy to pass water, less emissions, low energy consumption; 3, efficient stain removal; 4, physical disinfection, safe and reliable; 5, using a mild amino acid surfactant liquid formula, with multiple functions of washing and protecting, not hurting clothes, gorgeous as new, "no classification, cleaning dirt, sterilization and taste, soft clothing"; 6, high environmental protection, Easy to degrade, the laundry liquid uses amino acid surfactant, its biodegradability is above 99.9%, achieving the highest degree of degradation of similar substances, and minimizing the impact on the environment after discharge. The degree is in line with the low carbon environmental protection concept.

detailed description

The invention will now be further described in detail by way of specific examples.

The amino acid adult laundry liquid of the invention comprises an amino acid surfactant; the amino acid surfactant is used as a main active ingredient; the amino acid surfactant is mainly alanine type surfactant, and the alanine type surface The active agent accounts for more than 60% by weight of the total surfactant, wherein the alanine surfactant is more preferably 70% by weight or more of the total surfactant; the alanine surfactant contains at least the concentration. It is one of 98% or more of sodium N-lauroyl-L-alaninate and sodium cocamidopropionate.

The amino acid adult laundry detergent also contains water, glycerin, sodium hydroxide, DOE-120 methyl glucoside polyoxyethylene (120) ether dioleate, CAB-35 cocamidopropyl betaine, AEO-9 fat Alcohol polyoxyethylene ether, carson and flavor.
