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.. …
-
Right, Lotionrpo 165 is tried and true, just wondering if there are any potential pro's and con's about it compared to BTMS.
-
I don't see why the other ingredients would hurt, it could even make formulation a bit simpler by e.g. removing need for separate addition of cetyl alcohol - a nice not too waxy thickener/stabilizer.
-
Stability og BTMS + cetyl alcohol generally seems good enough, and sensorials are even better than 165 IMO! And what about adding something like 3% DuraQuench IQ SA, Croda "Cetyl alcohol, Isostearyl Isostearate, Potassium Cetyl Phosphate,Cety…

Thanks! Haven't had luck with Xanthan, Perry, have you used them to make clear low pH formulas?
-
USA, sales $100-500k range :)

(Quote) Using capric/caprylic triglycerides. Experienced it personally!

How about Saccharide Isomerate?
-
Acne is too broad, you'd have to make a product that appeals to women of a certain age group with fungal acne specifically.
-
(Quote) Thanks Perry, Albeit email marketing to works great, the problem is scaling to get the emails in the first place. You could try to rank for long tail stuff if you go for option b and have a niche product, SEO is however its own …
-
The market is completely flooded with brands, it's extremely hard to stand out, even if you're venture backed most still fail. There's huge survivorship bias, Perry mentions "Drunk Elephant", a brand being sued by L'Oreal for patent infr…

Natrosol 250 HHR was also rec, any experiences?
-
In my experience as long as you use a low percentage of acid, low pH is not a problem, like Pharma says, it's buffered away by the skin. Even though the acid is a solution easily loses protons, there isn't that many of them.
-
Sepimax seems like a good suggestion, had some issues with xanthan in low pHs before.
