What is hydroxyethyl cellulose used for?

Production Process of Hydroxyethyl Cellulose

The production process of hydroxyethyl cellulose is relatively complex, involving multiple steps such as chemical reaction and physical treatment. In brief, the process mainly includes several steps such as raw material preparation, etherification, neutralization, washing, drying and crushing.
Engineers mainly choose cellulose as the starting raw material, and after pretreatment to get suitable cellulose pulp meal for reaction.
Next, through the etherification reaction, the cellulose pulp meal is etherified with ethylene oxide under the action of an alkaline catalyst to generate hydroxyethyl cellulose.
After completing the etherification reaction, the remaining catalyst and unreacted raw materials are removed by neutralization and washing steps.
After drying and crushing, the final hydroxyethyl cellulose product is obtained. The whole process is rigorous and precise to ensure the quality of the product.

What should I pay attention to when buying hydroxyethyl cellulose?

  1. Product specifications: Different product applications require different qualities of hydroxyethyl cellulose. Before purchasing, it is necessary to clarify the viscosity, solid content, application range and other indicators of the required products to ensure that the selected product meets the requirements of use.
  2. Manufacturer&#;s reputation: choosing a manufacturer with a good reputation can ensure the quality of the product and the stability of supply. You can learn about the manufacturer&#;s operation by searching the internet, consulting with industry experts, checking social media, and so on.
  3. Price and cost-effectiveness: The price of hydroxyethyl cellulose varies depending on cost, specification, quality, brand and other factors. When purchasing, you should choose a reasonably priced product while ensuring quality.
  4. After-sales service: Understand the manufacturer&#;s after-sales service policy, such as product return, technical support, etc., to ensure that problems encountered in the process of use can be resolved in a timely manner. If you have questions about the product, be sure to ask the supplier for clarification before you buy.

Hydroxyethyl Cellulose

Hello guys, I need help.

I have failed so many samples now, I think it&#;s time to borrow your brains.
I&#;m having problem with thickening my surfactant system with HEC.

Formula is around this:

Phase A
69.5% Water
12% Sodium Lauroyl Methyl Isethionate 
12% Cocamidopropyl betaine
4% Coco glucoside
1% Euxyl PE

Phase B
1.5% HEC 

Phase C
q.s. Sodium Hydroxide 30% to pH>8

1) I combine phase A under low shear (overhead mixer) until homogenous.
2) I add slowly HEC until fully dispersed and homogenous. Mix under low shear for another minute or two. ( I&#;m making sure pH is<7 )
3) Add phase C to pH > 8 (usually end up around 9)
4) I mix and mix and mix. (I do not lower the pH to get the HEC time)

I come next day and there is this HEC layer floating on the top or sitting on the bottom. 

I tried mixing it for longer, shorted, increasing pH higher. 
Nothing helped. Am I missing something? 

Thanks guys!
