What is your preservative? my suspect is conservation problem or perfume or both.

Actually it is full formula and it is not my formulation just i want to correct it. So by searching D-Panthenol is already not liposoluble.

To find the cause of separation I added ingredients one by one so what I found out there it seems no issue

@Cafe33 @Dirtnap1 @chemicalmatt @Paprik @ketchito any comments please?

[Fekher]

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

[Fekher]

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.

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?

@ketchito any share about free sulfate shampoo (best thickener, best surfactant? … according to you)

@Cafe33 can you please tell me if ultrez 20 can give lovely sensory effect for free sulfate shampoo near to the one made with carbopol edt 2020?

@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

[Fekher]

I guess almost cosmetic is.

[Fekher]

Yes it is full formula not developed by me just I found out that Panthenol is not soluble in the product as first mistake then the orange solution has very near viscosity to Vit E.

Note : we are making formula by adding ingredients one by one to identify the cause so paraffin oil + grape seed oil +fragrance +Ethylhexyl methoxycinnamate seems mixcible without any issue with parrafin oil +fragrance +grape seed oil +Ethylhexyl methoxycinnamate

Note :viscosity of orange phase seems too near to Vit E

[Fekher]

Is there any benifet to fix pH lower then 4 for deodorant?

In other way will be more efficient as deodorant then deo with 4 range ph?

[Fekher]

I’am Just joking by 10,000 experts, about cream I meant even it is not hydro-liposoluble actif as zinc oxide it will be not problem by suspension with adequate viscosity.

[Fekher]

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 😉

[Fekher]

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

[Fekher]

Thanks a lot @Perry44 very useful, for the first point I meant when you make new formulation by first formulation.

[Fekher]

Agree with @Cafe33

[Fekher]

Thanks a lot for your precious informations.

[Fekher]

For my formulation even at 0.15% c12-15 decrease the transparency of hair wax.

[Fekher]

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.

[Fekher]

Actually it is cream wax then it needs heat.

[Fekher]

Thanks a lot for this share @Cafe33

[Fekher]

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?

[Fekher]

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?

[Fekher]

If really it is for sure don’t need a preservative this will be good news,however all industrial products use preservative.

[Fekher]

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.
