The amino acid-terminated methoxypolyethylene glycol-polylactide segmented copolymer is taken as a main surfactant for the ecological laundry detergent, the ecological laundry detergent has the advantages of strong decontamination force and low foaming; the ecological laundry detergent has the advantages of good environment compatibility, no biological toxicity, biodegradability, and environmental pollution.
Description
Technical field
The invention belongs to textiles clean-out system technical field, be specifically related to a kind of ecology laundry liquid.
Background technology
Along with the raising of people's living standard, washing liquid has become the daily necessities of each family.The demand of people to articles for washing is also more and more higher, except the detersive power required, also requires other function, and such as gentleness does not hinder hand, easily rinsing, environmental protection etc.
Washing liquid is in the market be main nonionogenic tenside with fatty alcohol-polyoxyethylene ether or isomery alcohol ether mostly, composite with polyoxyethylenated alcohol sodium sulfate, Sodium dodecylbenzene sulfonate.
The features such as it is good that the washing liquid wherein based on fatty alcohol-polyoxyethylene ether has detersive power, the easy thickening of system, but defoaming is not so good as based on the washing liquid of isomery alcohol ether.Relative, good based on the washing liquid defoaming of isomery alcohol ether, easy rinsing, but detersive power is slightly inferior to the washing liquid based on fatty alcohol-polyoxyethylene ether.
Aliphatic alcohol polyethenoxy simultaneously in nonionogenic tenside and isomery alcohol ether cause the concern that variability also causes people, such as cause unreacted oxygen ethene and low polyoxyethylene during ethyleneoxide addition because it is excessive, and two polyoxyethylene ring structure be dioxan (Isosorbide-5-Nitrae).
To strengthen gradually along with environmental consciousness and the requirement of biological safety improves constantly, develop low skin irritability, lifeless matter toxicity, environmental protection washing liquid be the task of top priority.
Summary of the invention
The object of the present invention is to provide a kind of laundry liquid being principal surfactant with the methoxypolyethylene glycol-polylactide block copolymer of end group of amino acid, its strong detergency, foam are low; There is good Environmental compatibility, lifeless matter toxicity and biodegradable, environmentally friendly simultaneously.
A kind of ecology laundry liquid provided by the invention, by weight percentage, composed of the following components:
All the other are water, and its gross weight meets 100%.
In the present invention, amino acid based methoxypolyethylene glycol-polylactide block copolymer structure is as follows:
Wherein R is amino acid based, a numerical range in 30-150, b numerical range at 8-30.
In the present invention, the molecular-weight average 1800-18000 of methoxypolyethylene glycol-polylactide block copolymer;
The structure of described amino acid based R is for shown in following formula (II):
In formula (II), R
