How do I dissolve 70 of AES in water?

Answer your questions one by one.

1) AES is easily soluble in water, AES aqueous solution is easy to form rod-shaped, insect-like or reticulated micelles, and under the action of electrolytes, micelles are more easily formed (AES salt thickening is this principle).

AES content below 28% is a colorless transparent liquid without electrolytes, and above 70% content is a paste-like translucent viscous liquid. Between 30% and 60%, it will become a very viscous gel. Therefore, the national standard stipulates that the commodity AES has two content specifications: 28% and 70%.

2) 70% content of AES dissolution, if the preparation of dish soap and other products, diluted concentration is less than 28%, be sure to pour AES slowly into the water when adding, and constantly stir, adjust the water flow and stirring speed, minimize the production of bubbles, the water temperature of 30-40 degrees dissolves faster, but generally takes half an hour or even longer.

Note that water should not be poured into AES, as it will gel quickly when the AES is diluted to 30%-60% during this period, and it will continue to dissolve very slowly. (But it will definitely dissolve in the end anyway).

3) AES is very resistant to hard water, which means that the detergency and foaming ability of AES are almost not affected by hard water. During dissolution, hard water can be insignificant when diluted into a low concentration AES solution because it contains more electrolytes than distilled or purified water. However, when diluted into a highly concentrated product, trace amounts of electrolyte can also increase the concentration and strength of micelles, and its effect on the dissolution rate can be fatal.

4) If the landlord needs about 30% AES solution, you may wish to contact the manufacturer to buy the product with 28% content directly. But shipping and packaging costs are an issue.

Another killer feature for you: dissolve some ethanol, propylene glycol or urea (mixed or single component) in water in advance when diluting, they can change the polarity of the solution and reduce the strength of micelle formation, and the effect is obvious.

But this killer feature is double-edged, once these ingredients are dissolved into the AES solution, this AES solution will no longer thicken as easily as before, at least slightly worse. Of course, the landlord doesn't need to thicken, then it's OK.

Isn't the water you use distilled?

The solubility in water of 25 AES is greater than 15 (sodium dodecyl sulfate 25 solubility in water is about 15, but the solubility in water is inferior to AES).

So AES should be blind and starvation is completely dissolved.

The content of AES = (65 masking 565) * 100 = grinding solubility) concentration = 115g L

Soak 70% AES in cold water overnight, it can basically dissolve all of it (effective in winter), and stirring regularly will accelerate the dissolution.

The solubility in water of 25 AES is greater than 15 (sodium dodecyl sulfate 25 solubility in water is about 15, but the solubility in water is inferior to AES).

So AES should be completely dissolved.

The content of AES = (65 565) * 100 = solubility) concentration is = 115 g L

Neutralize the sulfonic acid and base with about half of the water first, and then add AES while it is hot, and it dissolves quickly.

Add perchloric acid to smoke or add hydrogen peroxide.
