Cosmetics vs Drugs. By definition, the first group should only clean, refresh, and temporary change appearance, not produce lasting changes. And when it comes to drugs, even with the most “well-researched” if you look closer, you often see bias in how the clinical trial was conducted.

Thanks, @Pharma! Well, it is a moisturizer and it does give a bit of a viscosity boost IMHO, but then I haven’t seen how it feels without it, perhaps the difference is negligible.

Haha @ngarayeva001 ) Tears of virgins couldn’t be ethically sourced, though.

The website also mentions that they source herbal extracts without preservatives and then pack products aseptically. But how can a rose extract be aseptic unless you distill/boil it? Or is it how it’s extracted in the first place?

Mostly thinking to approach it similar how commercial kitchens are set up: no materials but basic tools are provided.

Also, henna works best in acidic pH. But it can stain the skin

February 15, 2019 at 11:44 pm in reply to: Shampoo without surfactants? What do you think of this formula:

@”Dr Catherine Pratt” I tried this one: https://www.hyperbiotics.com/products/activated-charcoal-probiotic-toothpaste
It has no surfactants, but the problem wasn’t the lack of foam, it just has no density to it, so it ends up falling through the bristles instead of transferring onto the teeth.

@Vnnil It’s interesting you mentioned this since some users who buy this product mention that they just use conditioner instead of shampoo.

haha ) right, a shower is better. Thanks for comments, folks. Users seem to be very pleased with the product but then again, could be false reviews.

@Microformulation and @MarkBroussard used Naticide at 0.7 and it passed the challenge test by an independent lab in the UK. Water 93%
Just FYI.
It has a pretty strong smell but customers find it pleasant so no additional fragrance was used. It is very expensive. INC: fragrance.
The formula is: water+withc hazel, carbomer +ta+naticide+prEbiotic blend
