    For sure it can be solution mixing with clear gel, the question is what is the level for each one?

    Nice answer from @Paprik then even sles is 70% the level of A.S still quite low. Then why using 2%sodium cocoyl glutamate and 1.5% decyl glucoside in no free sulfate shampoo I can’t find any benifet from that, the level of guar seems low then the level of amodimethicone seems high and almost will can stability problem.

    April 24, 2024 at 11:22 am in reply to: EDTA , viscocity

    I’am working for making balsam with<div>

    <div>

    Water qsp

    Citric acid : to ph 4.5 or lower

    Cetearyl alcohol 5%

    CATC 5%

    Perfume 0.3%

    Preservative 0.1%

    Edta: 0.1%

    I see lot of formulation with lower level of Cetearyl alcohol and CATC and thicker all formulation seen without edta so my suspect that EDTA is the main reason to not get thick balsam.

    So is my guess right? Then any explanation for that phenomenon?

    @PhilGeis for hair wax which need 80 degree C will better using parabens with Phenoxyethanol (I read that phenoxyethanol is descativated with high ethoxylated) or parabens with kathon cg (I guess kathon cg can’t added in 80 degree C)? Have you better suggestions if no one is good system of preservation for hair wax with 30% ceteareth

    Your formulation didn’t reach the 100%, then it lacks just water?

    For soap effect may changing emulsifier can be solution or make combination with other one. In general the ratio between emulsifier/oil seems not good (low) even with the presence of xanthan gum.

    June 2, 2024 at 4:58 pm in reply to: What is, the best alternative for Aluminium chlorhydrate for dedorant?

    I see professional formulation that contains zinc pca, zinc oxide and zinc ricin oleate.

    Castor oil seems for can have some effective job because zinc ricin oleate is already a drevative from him.

    I’am working for cream product so solubility is not a problem. And blogger for me as professional are not a reference however I can find some professionals formulation wich contains baking soda, corn strach, titanium oxide and coconut oil

    For the proverb, that’s why i’am here to hear from 10000 experts 😉

    The definition seems more correct that antitranspirant is product wich block transpirtation from skin in practice aluminium chlorohydrate doesn’t.

    Because all other ingredients are water phase just I have 5% liquid vegetable oil and because it is liquid there is no need to heat only if it is stability’s need.

    Even in process all I watched use hot process however no one of toothpaste paste need hot process, I guess hot process give better reaction then better viscosity and cohesion?

    Thanks a lot @ketchito actually in general the used gelifiant is sodium carboxymethylcellulose not as I wrote, then I see some formulation use combination between sodium cmc and xanthan gum.

    I used hpmc adding food grade of sodium bicarbonate the viscosity decrease dramatically going to water viscosity starting with higher viscosity then gel toothpaste.

    So any specific carateristic of Carrageenan which make it good choice for toothpaste?

    I was working with your preservative untill i discovered that it is not fungicide effective, however oxide zinc in sush level will help a lot in preservation so your preservation system is not sure.

    Then may just increasing the level of Peg-8-Hydrogenetad Castor Oil will do the job without any additional ingredient so may you have 3 samples or more to do.

    I find convincing costumer that it is the best choice better then following costumer in bad choice unless don’t convince him and don’t say that it contains silicone just when he try it he will like the texture (professional formulator should make the best choice follow the costumers you will make the worst hhh)

    Then may you will try C12-15 alkyl benzoate or peg7 glyceryl cocoate but dimethicone almost too better.

    With which language q. s? I’am always searching about q.s ????

    Then for spreadability and other needs I guess dimethicone will gives you all.

    @ketchito Why not using slat vs sodium citrate for increasing the viscosity?

    You are welcome @Abdullah what I shared says that it is softener for water, then I did not understand your last question.
