    @rishabhsoti
    I agree with @afatoh , you may use xanthan gum.
    You could also try adding carboxymethyl cellulose (CMC) as thickening agent.

    You need a thickening agent in your formulation.
    But if you are using SLES, salt (sodium chloride) would serve as the thickener.

    You cannot make deionized water at home without any equipment. Distilled water on the other hand can be easily made by boiling tap water, then condesing the water vapor/steam.
    Depending on your country, you can buy deionized water from local hardware stores or chemical retailers/suppliers. It is quite cheap, around Php 25 (roughly $0.50) for 5 gallons. You can buy distilled water in any grocery stores for a dollar or two.

    Thank you sir @mikethair. I am making liquid soap based from SLES and LABS. I guess I’ll be adding preservative now

    I’ll give you an update @Pattsi if my preservative-free dishwashing liquid formulation becomes resilient to any microorganisms (I highly doubt that it would last for years, but if it does, I’ll share my formulation). Cheers mate!

    Awesome reference you got there sir @Perry . I guess I’ll now be adding preservatives. I hope tardigrades won’t be living in my soap anytime soon.  
    Thank you sir @Perry

    Thank you @chemicalmatt. I’ll check my local suppliers if they sell Isothiazolinones.

    @yash42440, don’t remove the CAPB, because it makes your product more foamy. You could lower it to 1% then add 1% to 2% CDEA. If this does not address the issue of soapiness even after rinsing a couple of times, try removing the glycerine. 
    Still, if it doesn’t solve the problem, try this formula
    94g LABSA
    26g CDEA
    862mL Water
    1g EDTA
    1g Methyl Paraben
    1g Perfume/Scent
    2g Salt
    12.5g NaOH
    0.5mL colorant
    (Total yield of 1Liter)

    @Abdullah, try to do a salt curve analysis. Sir Perry, the Admin of this forum, posted an detailed instructions on how to do it. Here is the link

    https://chemistscorner.com/salt-curve-analysis-how-to-control-cleansing-cosmetics/

    I followed it and was able to determine the desired amount of salt that I need. 

    Cheers Mate!

    June 24, 2020 at 5:19 pm in reply to: What is the difference between LABSA and LAS

    Thank you @chemicalmatt. I recently had a chat with my supplier. They said that it is acidic. This made me think that they screwed-up in labeling their products. 
    Soon after, I tested it by adding a solution of NaOH . It became light brownish (nearly white) color. Also, the solution heated up a little. So I think that the LAS that they’ve sold to me was not LAS at all rather LABSA.

    Hi there @luiscuevasii, thank you also for commenting. I haven’t check the pH level because the pH testing paper that I ordered is not delivered yet. Looking forward to test its pH before mass production.
    I also plan to sell a high quality and high priced variant of my dishwash liquid, what do you think I should add or increase in my new formulation?
    Thank you so much!

    Hello @Chirag, thank you commenting. I’ve  adjusted everything and already converted it to percentage. The LABSA is colour brown, and I did not neutralized it. Realizing my mistake, I started all over again.

    After neutralizing the LABSA and doing a salt curve, I was able to achieve a clear product, and no precipitation.
    So here is the percentage of all my raw materials
    8%SLES
    1.5% LABSA (Neutralized in NaOH)
    1% Coco DEA (or CDEA)
    0.5% Coco Betaine
    89% Tap Water
    I also added some preservatives and 1 gram of EDTA Tetrasodium for every liter of my dishwashing liquid

    The results were good however I’m not that satisfied with the foaming. What should I add or increase in order to improve foaming?
    What do you think of this new formula of mine? 
    Thank you so much

    I had that same problem before. The culprit in my opinion is the coco betaine. I added CDEA and a little bit of Coco Betaine (around 1% to 2%) in my formulation. Everything went well so far.

    Hi Everyone!
    I’m Billy, an electrical engineering student from the Philippines. I’ve been trying to perfect my dishwashing liquid formulation for more than a year now. I’m looking forward to learn more and share my experience in this forum.
