I read the instructions for ultrapuregel, and it says that for maximal emulsion stability add it to the water phase pre-emulsion, but for maximal viscosity add it after emulsification after cooldown. I guess both ways usually work, but the question…
-
Thanks for the input, yes the factors other than stability can be added with other ingredients, but still choosing and emulsifier that performs well with regards to those factors could be beneficial. My main concern with this formula is penetration…
-
Great, will give it a try :)
-
Interesting, does it have any other beneficial properties or downsides? Where do you buy it?
-
Just a bit foamy at least, most 10% formulas are not foamy whatsoever.
-
It can definitely generate a very smooth product giving your skin a feel similar to conditioned hair, but there are other ways to achieve that.
-
Good tip! Let's see if they ship to the US
-
Or maybe just go for low amounts of essential oils..

It is an antioxidant but that is perhaps not reason enough? The product is already somewhat green from sencha green tea.

Good tip, on paper looks like it should work and it's cheaper than sclerotium gum ($77 vs $55/lb bought online). Any other options?
-
Oh and HEC unfortunately does not give a clear formula, likely due to the low pH / lactic acid.
-
Definitely convinced it's not worth the effort by now..

A reference to a dermatology book in Portuguese that's not available online doesn't convince me topical gluten sensitivity is impossible, I'm not claiming it's common but I don't think that enough to rule it out. Jacques CMC. Ramos-e-Silva M, Castr…

It's the after effect minutes after application I'm interested in, a lot of AHA lotions will make your skin -feel- dry after.

Thanks @emma1985 and @ketchito , here's a reformulation with more triglycerides, cetyl alcohol, btms and dimethicone + added safflower seed oil and lauryl laurate as a slip agent and lastly more glycerin as a solvent for azelaic acid (could make it…
-
Thanks @ketchito - i think the triglycerides can do the job of mineral oil here, but how much and what CPS of dimethicone would you suggest?
-
Thanks Bill, seems like more glycerin might also help then up to say 6%? I've used BHB before but would like to avoid minimum orders for this one. What do you think of the following changes for the next iteration? +3% Safflower seed oil (high lin…
-
Yes certainly, do you think Lotionpro 165 would be better? What about just adding more Cetyl Alcohol instead?
-
(Quote) Around 145C, but it's soluble in other oils and organic solvents so it generally solubilizes without needing high heat.
-
(Quote) Good point I forgot about that, replacing it with sclerotium gum.¨ (Quote) I have a lot of customers with acne, and I still (urgh) am prone to break out on both face and body, so anything with some benefit for acne but also normal skin is …
-
(Quote) Just my 5 cents, but from a marketing POV there's very little to gain by not using them (since it's so common now to be "free of" everything it's not a strong differentiator) and 99.9% of consumers just care about performance. I'd…
-
(Quote) Aka soaping effect? You could add 1% dimethicone to get rid of that. (Quote) Kudos for doing elaborate experiments. Are you making products for yourself or for others btw? (Quote) Why aren't you using it then? ;) Re: Jojoba oil, if I r…

Duraquench should feel different than ISIS again, might be worth trying. (Quote) Floratech propose the hydrolyzed (basically Floraester 20 C42:2 split in half) K20W ester blend traps glycerin on the surface of the skin increasing its humectant pot…
-
(Quote) Why not try both? How much did you use? I've seen one study that supports 8%? CCT reducing TEWL 33% for up to 6 hours https://pubmed.ncbi.nlm.nih.gov/19296892/ but there also also studies showing ISIS reducing TEWL more than the equivalent …

Very interesting, we do sell some to the EU at least but not from the EU (yet), what is the reasoning?
-
According to ingredientstodiefor sclerotium gum works well with cationic ingredients

Cerave used BTMS-25 is all its moisturizers at around 3% - seems to work fairly well for them (so around 0.75% Behentrimonium Methosulfate) - not a lof of research on the methosulfate form, the chloride form does have ocular irritation potential.. …
