Embodiment
The preparation of alkyl ether carboxy acid salt/chitosan emulsion
11.19g Emulsogen Col 100 (oleyl alcohol polyglycol ether (10EO) carboxylic acid for being obtained from Clariant) are molten
Solution protonates in deionized water (500ml) and by molar equivalent HCl.Then chitosan LMW (2.5g) is added, and makes this mixed
Compound stirs 24 hours.Products therefrom is filtered to remove any insoluble reactant by garrha, then oozed out to remove trip
From acid.
So cause to produce the aqueous emulsion comprising chitosan and alkyl ether carboxy acid salt.
Softening performance
Emulsion is tested in itself and in cloth-washing detergent（Preparation A）In in contrast to various testers（Water and its laundry are with washing
Wash agent formulation in itself）Softening performance.
| Preparation A-composition | Wt.% |
| LAS acid (anion surfactant) | 5 |
| SLES (anion surfactant) | 2.5 |
| NEODOL 25-7E (nonionic surfactant) | 7.5 |

| NaOH | To pH 7 |
| Water | To 100 |
Test four kinds of preparations:-
1. water
2. preparation A (to wash 1.25g meterings every time)
3. the emulsion of chitosan/alkyl ether carboxy acid salt (to wash 5g meterings every time)
Preparation A 4. (to wash 1.25g meterings every time)+emulsion (to wash 5g meterings every time).
The experiment, which is related in 1 litre bottle, measures 500ml water and 4 towel cloths.The weight of liquid and cloth ratio is 10:1.Also
A certain amount of preparation is added, stirs the bottle on Stirring device at room temperature 30 minutes to replicate washing machine.Removing is washed
Wash and use liquid, rinse every group of towel cloth twice using 500ml water, continue 10 minutes, again in room temperature on Stirring device
Lower progress.Hang and do the towel cloth.
The towel cloth through processing is evaluated by 10 group members, they are divided into 1-4 etc. by group member according to pliability
Level (4=most soft).The average of total grade is taken to provide pliability fraction.
| Preparation | Average rank |
| Water | 1.1 |
| Preparation A | 1.9 |
| Emulsion | 3.3 |
| Preparation A+emulsion | 3.7 |
The emulsion is apparent from from pliability, and the softening that is greatly improved than water tester is provided.Institute also can be clearly seen
State the softening that laundry detergent composition is also greatly improved in solution.
