They already told you. %0.1 EHG with % 0.9 phenoxyethanol

[Abdullah]

@ozgirl the pH was between 4-5 for both before mixing and i didn’t note what it was after mixing but it wasn’t very high or low

[Abdullah]

@Pharma that is cool ????.

So is biodegradability the only problem with EDTA or it has any negative effect for consumer too like irritation or when absorbed from leave on product, when used at %0.1-0.2?

[Abdullah]

@Perry thanks. 

[Abdullah]

For your formula, i would suggest remove the soap, reduce eo to %0.3, CAPB to %5 and increase the Sulfoacetate to make the total active surfactant around%10. 

For eczema, i have it too. And there are 3 treatments for it that i know and have used.

1. Steroids

2. Suppressor of your immune system
3. Petrolatum

The one with least side effect is petrolatum according to my knowledge and experience.

[Abdullah]

@Pharma that was a wonderful explanation ????. I will not think of citrate as an alternative to EDTA anymore.

Another question:
If Cu, Fe and Mn are the metals of concern in cosmetic, according to the chart above EDTA is a lot more stronger than GLDA but the chart below shows GLDA functions better than EDTA at same quantity. Any thoughts on this?
The chart below is from supplier. 

[Abdullah]

@Pharma thanks a lot

[Abdullah]

@Perry @Pharma in this list Glyceryl stearate is mentioned after phenoxyethanol. Does it mean the amount of GMS is less or equal to phenoxyethanol? 

[Abdullah]

@ngarayeva001 pH is around 5.5

At what pH range GMS se would be stable? Evonik says 6.8-8.2

[Abdullah]

@RDchemist15 thanks 
Very informative

[Abdullah]

 

how are companies like Tom’s of Maine able to make mild, minimalist shampoos with
decyl glucoside+glycerin+salt+xanthan gum…yet my minimalist copy cat versions is just harmful to my skin? 

They lie about there ingredients. At least on there website.

This is there ingredient list:
Water, Caprylyl/Capryl Glucoside, glycerin, sunflower oil, decyl Glucoside, inulin, xanthan gum, fragrance, lactic acid, citric acid, carrageenan, vitamin e, soybean oil.

[Abdullah]

What about other commercial hand washs? Do they foam too or not? 

[Abdullah]

@Microformulation the some water was separated from cream on 3rd day.
they also said the CAS # is 31566-31-1. So does it mean it is GMS?

[Abdullah]

@ngarayeva001 i saw water separation on 3rd day. The cream is not stable. 

[Abdullah]

@Pattsi thanks a lot

[Abdullah]

@Microformulation they said the CAS # is 31566-31-1. 

If the HLB of GMS se is 5.8, does it make o/w emulsion or w/o emulsion if used alone? 

[Abdullah]

I did add t table spoon of this cream in room temperature water and mixed. This is the result

[Abdullah]

@Zink what are the other ways to achieve such felling in a non-ionic emulsion? 

[Abdullah]

@Microformulation in most of  eastern countries they don’t do a lot of documentations for these small purchases especially if it is from a reseller. The cas no is not mentioned on it. I did email the seller after you mentioned it and am waiting for his answer if he knows. 

[Abdullah]

@Aziz that has confused me too. 
It doesn’t have se

Is has o/w written instead of w/o

I have purchased it from a trader and he doesn’t know this technical parts of it. 
I don’t think that it may be a printing mistake

[Abdullah]

@”Dr Catherine Pratt” @Paprik 

I made some samples from it to find out what it is. 

First I made a sample with Stearamidopropyl Dimethylamine and it didn’t even make a lotion.
SPDMA    %2
This emulsifier  %3

Second sample made a good looking cream and is completely stable since yesterday. No other thickner or stabilizer used.

Petrolatum   %5
Vegetable oil  %1
This emulsifier  %6

Does this mean it GMS se?

[Abdullah]

@ngarayeva001 thanks 
For stability if i use a bit more cetyl it would be equal to stearyl. They are not expensive

[Abdullah]

Thanks @jemolian

[Abdullah]

I think if you are doing business from selling it, the most important part would be how to cut the costs. Tubes are at least half the price of bottle with pump. 

I  use pump but now i am changing it to tube because of the price. So it may be worth considering.

[Abdullah]

Why don’t you use tubes? 

They are better preserved from contamination by customer

They are less expensive

You can write everything on it and  dont use extra box for it. (Extra cost saving)

Customer can carry it every where and use it more often.(more money for you).

It looks better than jar unless your jar is so luxury and costs 10 times more than what the product itself cost.

In business

You can not make profit when selling.
You can make profit when purchasing.
So %70 of your focus should be on reducing the costs if you want to do business.
