@zwapp,Thanks for your extensive answer.I agree
on the pH testing, I prefer meters aswell. Point is, I’m only making stuff for
myself, so I’m not ready (yet) to invest in the highly accurate professional
precision equipment, like what I’m working with professionally.
Because of that, I keep using strips next to the meter to have a kind of double check.
Also my scale will not be as accurate as the ones I work with, but it does the
job for my own concoctions.
I can weigh a minimum of 10 milligrams on my scale, the accuracy is good enough
for my homemade stuff. This type is used for weighing gold/diamonds etc. It also
has a calibration function.
Thanks for your compliment, I also do indeed believe in rigorous science only.
And I sure am very eager to learn.
It’s interesting to read the mechanism behind the niacin flushing. Inflammatory
reactions are indeed not harmful per se to an extent. It’s a natural and
helpful reaction of the body, which is the main reason I don’t easily take for
example NSAID’s for this purpose. Personally, I also like the feel of blushing
flushing. Not necessarily because of the increase of O2 to tissue, but it’s
just an overall nice warm feeling. Maybe I’ll change my opinion when I once
will be menopausal.
I do like to add anti-inflammatory and
soothing ingredients because of the benefits for eczema and rosacea.
Personally, I don’t care much for all the supposed anti-aging, anti-wrinkle
stuff. Maybe because I don’t have wrinkles at all, though I’m almost 40. And apart from tretinoin, I don’t believe
the supposed effects of all those ingredients.
My 3 sisters (I prepare stuff for them aswell) do have wrinkles more or less,
but unlike them, I never sunbathe or smoke and I kind of have a strict skincare
regimen just because the skin is an important organ and I like to care for all
of my organs. Sadly I can’t convince them to give their whole skincare routine
a thorough look, as the cleaning part is essential aswell. So is perseverance.
Only apply a moisturizer once a week or something won’t do much either.
But back to the niacin topic. I was wondering if niacin had any other bad
effects on the skin. I can’t find much about niacin on the skin. Do you mind
telling me for what reason exactly you put it in the scalp treatment?
About your spreadsheet, I do it the same way. Like what I’m used to professionally.
Indeed, a space where you can place notes. If something went wrong for example,
it’s good to know the exact amount you’ve used since there always is a
slight deviation within the perimeters you work with.
As a very general rule, I would give it 24 hours to see the fully thickening effects of any emulsion. I have actually noticed a difference within the first 4 to 6 hours, 12 hours, 24 hours, 36, and even up to 48 hours, after that it seems to finish stabilizing and remains the same no matter what it's made up of (as a generality, so don't jump all over that statement).
As a side note, because Cetyl Alcohol is a C16 (and the fatty alcohol equivalent to palmitic fatty acid), it will be a bit lighter and stiffer than the next step up, which is Stearyl Alcohol (C18 - the fatty alcohol equivalent to stearic acid), and is a bit denser, smoother... even though they are both common/good thickeners.
Of course no matter what qualities they have on their own, all that matters is what you're combining it with, because the conglomerate is the outcome.
Just let it sit for a couple of days before drawing any major conclusions.
Has anyone ever studied the effect of combining natural thickeners to emulsions that also contain Cetyl Alcohol? I am making some hard to thicken emulsions and I've tried a couple of natural thickeners but if they are very high in Molecular weight they thicken the emulsion too much. Has anyone tried HEC, CMC or other natural thickeners? My instinct tells me to try lower molecular weight natural thickeners but I don't know if these will do the trick or not. Also, if using natural thickeners, should I lower the amount of Cetyl and Stearyl Alcohol?
Thanks for any help or insight that anyone can give me on this.
