@Pharma thanks

@Pharma i wanted to add ethyl Lauroyl Arginate HCl and EDTA in lotion both for preserving the product. They also formed salt as photo.
Does it mean they dont help the preservative system anymore?
-
Also SLES
-
Increase Glutamate to at least %40 and decrease glucoside to max %4 the problem will be solved.
Do you have preservative?
-
@Pharma does it mean it is not compatible with cationics?
-
@Pharma thanks
-
@”Dr Catherine Pratt” have a look at this
-
@RedCoast thanks ????

ozgirl said:I haven’t tried cetyl esters so I can’t really comment on that.Polyquaternium 10 might add some additional benefits that BTMS doesn’t but you should just try it with and without Polyquaternium-10 and see if there is a perceivable difference.
May I ask what additional benefits pg10 has over BTMS?
-
They already told you. %0.1 EHG with % 0.9 phenoxyethanol
-
@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
-
@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?
-
@Perry thanks.
-
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. PetrolatumThe one with least side effect is petrolatum according to my knowledge and experience.

@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.

@Pharma thanks a lot
-
@Perry @Pharma in this list Glyceryl stearate is mentioned after phenoxyethanol. Does it mean the amount of GMS is less or equal to phenoxyethanol?
-
@ngarayeva001 pH is around 5.5
At what pH range GMS se would be stable? Evonik says 6.8-8.2
-
@RDchemist15 thanks
Very informative -
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. -
What about other commercial hand washs? Do they foam too or not?
-
@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? -
@ngarayeva001 i saw water separation on 3rd day. The cream is not stable.
-
@Pattsi thanks a lot
-
@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?
