Interesting, because i normally do 1-1 EO and Polysorbate20. I mix it together and than pour it in to liquid soap. I will try to make it again and will add more p20. Or i can add more p20 in to soap and mix again?

Thank you

I think i remember few years ago about sodium / disodium you were talking and i think it was mention there are different ph. 

Will deff try it and let you know here. Thx

[Rencelj]

Anyone ? I have SCG and recipe calling for Disodium. What is difference ? 

Thnx for help

[Rencelj]

I see Natragem 140 will work. Now need to test in water before adding it to product. 

[Rencelj]

I left our ghtc and replace with sodium pca,lactate and adding sucrose cocoate, but when i add sucrose cocoate it thich whole formula, quite a lot. Do i need to disperse it in soluble surfactant eg.coco glucoside ? 

[Rencelj]

Citric acit did not help/work. Will try tomorrow with lactic acid. With 0.2 and 30 min mix at 70 celsius. Lets see.  

[Rencelj]

I add citric acit in water befor i put in vortex so it swell better. But check ph. 
Trying for shower gel, but wondering if i am better with sodium PCA and sodium lactate.

Thx

[Rencelj]

Can Sodium PCA substitute Guar Hydroxypropyltrimonium Chloride? 

[Rencelj]

I did try in glycerine and than in water but is same. Also today, after 24h is still with dots/small particles. No orher ingredients, rather water and ghtc. 

[Rencelj]

And slo i have question, how do you thick formulation with sodium cocoyl glutamate ? I have problem with using it and carbopol ultrez 20 polymer. I rather dont use xantan gum (sticky gel and specific odour).

[Rencelj]

Thank you. I have OE in storage. Will try it. Thank you. Yes, they sugessted me already, but wanted to see also other options, since i have quite a lot of ingredients and wana test others before i order sample from BASF.

There are toons of silicones, sure. But dirrect replacement of it ?

[Rencelj]

If i buy chamber for stability test, can i give than stability test to myself/products after 8 or + weeks of controling? 

Because for CPSR , we need PET testing and stability testing. PET testing i will give to outsourcing lab, but stability testing i was thinking to do it in my lab/cosmetic production with chamber that has :

0-60’celsius with -+0.1 accuracy, fluctation 1%+-

humidity 50-90 %

timing range 0-999min

So on end i dont need other labs or outsourcing to make stability test of produucts that will be relesed on market? 

Regards

[Rencelj]

atleast this is what i found on net. But like i said, my question is if i can make also with centrifugation stability tests ?

Calculations: 

Relative Amount (%) = [Volume Instability Phenomena] x 100 

                                                 [Volume Total] 

Ex). Total Volume = 10 mL 

Volume of Settled Material = 1.0 mL 

Relative Amount = (1.0 / 10) x 100 = 10% Settling

[Rencelj]

So 3,5h at 3000 rpm is equal to 1 year stability?

[Rencelj]

But i see some companies have not done on temperature but on centrifuge. Do you think i can buy cenftrifuge equipment and do it that way ? 

Regards

[Rencelj]

Thank you all for help, 

i think my knowledge is to bad for this and best would be to find someone and pay it to make formulation.

I mix EO after cool down phase, when all surfactants are already mixed.

 Now i tried to add 2% polysorbate 80 and 0.5% EO. It got a lot better just a little bit cloudy. Adding any silicone will make it cloudy more right ? Was thinking to add polyquaternium 7 or something to make hair soft and smooth after washing

How do you mean by surfactants are not strong enought? 

Sodium Cocoamphoacetate (25%)  32%

Sodium Lauryl Glucose Carboxylate & Lauryl Glucoside (25%) 10%

Disodium Cocoyl Glutamate (25%)  6.4%

totall active = 12,1

Cocomide DEA:

” The International Agency for Research on Cancer (IARC) lists coconut oil diethanolamine condensate (cocamide DEA) as an IARC Group 2B carcinogen, which identifies this chemical as possibly carcinogenic to humans.^[3]

In June 2012, the California Office of Environmental Health Hazard Assessment added cocamide DEA to the California Proposition 65 (1986) list of chemicals known to cause cancer.^[4]

Cocamide DEA has a high irritation potential.^{[5][non-primary source needed] “}

[Rencelj]

Totally forgot. Mayby you could help me with shampoo reacting with essential oils? From Perry’s natural formula i get from nice texture and nice thicken form in to cloudy shampoo. No perservative yet added or any other feature ingredient. I tried to add EO and asap as i add, it get cloudy. I tried to use polysorbates, peg 40 castor oil and mix with eo and than add, but just wouldnt work. 

[Rencelj]

I totally agree with you. At the moment i dont have Cocamide MEA, but i have only DEA and that one is carcinogen. I cant find suppliers to even order it and test it from web page in UK. 

Mayby can i replace CAPB with Sodium C14/C16 Olefin Sulphonate ? 

I can also use this 2 if need:

coco glucoside glyceryl oleate 

Sodium Lauryl Glucose Carboxylate (and) Lauryl Glucoside (Plantapon LGC)

[Rencelj]

Thank you for leting me know, Hope this will be better to see.:

50,5% water

30% - Cocamidopropyl Betaine (30% active)

4% - disodium lauryl sulfosuccinate (powder) (30% active)

10% - Sodium Cocoyl Glutamate (25% active)

 sodium chloride 2%

 phenoxyethanol (and) ethylhexylglycerin 0,7

 polyquaternium 7  0.5%

 cyclomethicone   0,5 %

 provitamin b5       0,5%

guar hydroxypropyltrimonium chloride 0,3%

[Rencelj]

Hmm, honeyquad is nice for skin, but can be replaced with any other natural ingredient or will not make diference if i pull it out (for skin) ? Also will it make formula unstable or just less thicker ? if i leave it in formula ? 

[Rencelj]

What i found interesting is, i did as told and i must say i was really happy. But as soon as i add last ingredient-Hydroxypropyltrimonium Honey at 1% it brakes down thicknes. Probably react with carbomer. Can i avoid this somehow (not replacing carbomer/hoey quad)?

Greg

[Rencelj]

Thank you belassi for guides, will try it asap and let you know how will turn out. Bob, yes will try to use NaOH (10% solution) to thick carbomer. So best thing just to add to carbomer to achive ph of 5 - 5.5 right ? And than add oils in to it?
