Aloe barbadensis leaf juice
Good morning!
What are the incompatibilities of aloe gel with other cosmetic ingredients? Are they visible, or are they over time?

Have never had a problem and I use plenty of aloe vera.
-
Not even with polymers?
-
In emulsion?
-
Problems with all types of polymers: Aristoflex AVC, Sepinov EMT, all kind of carbomers (even ultrez 30, if you add more than 10% of aloe), acrylates, GelMaker EMU, even Sepiplus 400 that is supposed to be electrolytes resistant. Aloe Won’t cause lose of viscosity of products based on conventional thickeners (fatty acids, gums etc). I avoid aloe in creams and gels.
-
In emulsion? No. And I use 100% aloe vera in one emulsion.
-
But did you use aloe vera gel only with traditional gums and emulsifiers or even polymers?
-
@Belassi, I did many experiments with aloe including the one in the recent discussion about ultrez. I find aloe a very problematic material. I will really appreciate if you can post a formula of the emulsion you mentioned (emulsifiers, thickners and oils, I understand you might not want to post the entire formula)

I realized organic certified face cream with 7-8% of Organic Aloe vera gel and result is good.in.this case there aren’ t polymers or carbomers because they aren’ allowed by standard
-

Traditional emulsifiers or that plus carbomer. I don’t use polymers.

This is a 40% aloe vera gel made with Ultrez-20 just to show you that it is no problem to use Ultrez with aloe etc.
water 80%
aloe x10 conc. 4% C6040C
Ultrez-20 0.8%
NaOH 0.25%
Glucam E20 1%
Actives (d-Panthenol, licorice acid, plant extracts) 14.2%
- completely stable product -
The formula for a 20% aloe vera cream uses 2% of x10 concentrate = 20% aloe vera. Completely stable, we have examples 3 years old.
Stabilised with 0.3% carbomer (940) and 0.1% xanthan gum.
Water 70%.
The emulsifiers are 3% glyceryl monostearate and 1% polysorbate-20.
Oils, 6%.
Active ingredients, 12%.
Cetyl alcohol and stearic acid, 5%. -
Thank you very much Belassi.
I realized some formulation similar to yours but I have used polymer instead of carbomer.the sample are 7 months old -
You’re welcome. I get excellent sensorials without needing to use expensive polymers.
-
Thank you @Belassi. I have not tried this combination of emulsifiers and I am curious to try now. Do cetyl alcohol and stearic absorb fast(white foaming) without silicones? made one formula for my friend with honey powder, aloe x200 (20%) oatsilk and other ‘natural goodness’ that I usually don’t use. I had to make it with fatty acids and xantham. It’s a matter of preferences. Some people don’t like polymers and find them sticky. I prefer either polymers alone or a combination of polymers and fatty acids.

Do cetyl alcohol and stearic absorb fast(white foaming) without silicones?
Yes, providing the oils / esters are balanced and well chosen. -
@Belassi this is a true art
I heard that it’s possible but never could get to this point. I just add silicones and polymers and never ever use stearic acid in lotions. -
Slightly tangent question: but when putting together the LOI, do you list the aloe as if it is 20%, or by the amount of concentrate that you added?
-
I list the aloe as if it were 20%.
-
In creams with high % of Aloe but whitout polymers, do you insert always a buffer system?
-

Not really, no. There is a small amount of EDTA but only as part of the preservative system. -
I use naOH solution 30% to pH 5.5 but I don’t use a buffer system.Perhaps aloe vera gel ( acidic pH) can decrease final pH?
