@GabyD I think that when you’re trying to make a soap, the addition of alcohol isn’t necessary, as the surfactants will dissolve the lipid membrane. You can make a pretty effective sanitiser with 70% ethanol, 1.2% Sepimax Zen, 5% propanediol, fill with water to 100%. I wouldn’t sell it though, as it’s probably against the law (sanitiser is an OTC drug in the States).

@Doreen how did you get the easynov?? It’s really hard to get
-
Sepimax zen at 1.2%
-
@ozgirl Thanks so much!! I’m only really making cosmetics for my personal use for now, so if anything happens, only I will be hurt lmao
When I get into it a bit more seriously, I’ll make sure to get a lab to test the product for me
-
Is the smell of the raw ingredients really that off-putting? If not I’d ditch the fragrance. Maybe increase glycerin to 5% (it’s cheap regardless)..
-
Hi! Why would you include 4% NAG? I’ve only seen 2% used in clinical studies, so I would think that it would be enough. Adding more is probably just a waste of money (I think)..

@ngarayeva001 thanks for the tips
-
@Graillotion beautyever.pl (im located in Poland thats why)
-
@Perry Sure!
-
@Perry thank you for your tips!!
So should this work:
Buffer
Gluconolactone (my main Focus here)
sodium pca
carrageenan for thickening
preservatives -
@GabyD Can you tell me more about it?? Im really curious, I wanted to use that mix
-
!!!
Hey! So I changed the formula a bit (your tips + other forms/groups/logs etc)- Buffer
- Glycerin 2% (added)
- Gluconolactone 5%
- Sodium PCA 5%
- Betaine 5% (reduced)
- Green tea extract 0,5% (reduced)
- Green tea leaf powder 1% (reduced) (sensorial/visual appeal)
- Carrageenan 3%
- Allantoin 0,5% (reduced)
- Arginine 5%
- Pentavitin 3,5% (reduced)
- Sodium Benzoate+Potassium Sorbate 0,3%
- Phenoxyethanol+Ethylhexylglycerin 1%
- Disodium EDTA 0,02%
- Sodium Lactate q.s.
STILL included both preservatives, as phenoxyethanol is weak against mould/fungi and sodium benzoate Is weak against gram- bacteria
I think that the Carrageenan will provide enough thickness, but I’ll have to experiment.

Belassi said:In my experience, tea extract is problematic for two reasons.
1. It is an indicator. At pH >7 it is brownish-yellow. At pH <7 it turns pink. With that much it would be very coloured.
2. It is not very stable. In my opinion shelf life = or < 3 months. I couldn’t store the raw material for more than 3 months either, even at 3C.I no longer use it. Our one product that has it, I substituted pine bark extract (another indicator with similar colour response, but a lot more stable)
I have EDTA and Gluconolactone, that’s for chelating so it doesn’t go bad, but maybe adding some antioxidants like BHA or BHT to make it more stable? I totally didn’t know it changes colour tho

Belassi said:Other comments:
Over preserved. The first combination alone should be adequate.
More importantly, I do not see any logical physical result for this formula. Usually I can look at a formula and think, ok, w/o emulsion, or whatever, but this? I’m glad I am not the one spending money on ingredients to make whatever this is.I wanted this to be a hydrating and mildly exfoliating gel serum. I saw on other website, that phenoxyethanol itself isn’t enough for yeast and mold, hence the sodium benzoate. Tbh didn’t know about the betaine (my supplier said up to 10%, so I just maxed that out)
-
I found this paper https://www.in-cosmetics.com/__novadocuments/34292?v=635114705399500000 and when betaine was added to the water it was stable up to 1,4%!! Unfortunately it was 1:1 water to betaine but still I think it should help especially cause I want to heat it to 70c
-
Hey ngarayeva001! I was told that Betaine would reduce the stickiness. Should I add some Propanediol? 5% betaine and 5% propanediol in that case. Also I wanted to dissolve the Allantoin in the betaine (I was told that would help by my friend who’s a chemist and has their skincare brand). I also thought of adding BG for penetration enhancing, what are your thoughts?
