What expiration date have you set for your opened bottles of water?
It just feels like a waste to throw around 4 liters away from every bottle, but just like you, I'm also afraid of contamination. I don't boil it though.
You really don't need sterile water for cosmetics. You're not going to inject it I hope? ;) (Plus boiling won't sterilize it)
I am really curious what else was in that facewash? I've never had any visible growth so far in any of my f…
These are a few types of vegetable oils that I don't see very often in products:
* Cacay Seed Oil (INCI: Caryodendron Orinocense Seed Oil)
* Prickly Pear Seed Oil (INCI: Opuntia Ficus-Indica Seed Oil) => this oil is very expensive
* Kukui Nut Oil…
I've seen this brought up many times, that you gain final viscosity only after a day or 2 if you use fatty acids/alcohols, but I've never experienced it myself. Viscosity right after cooling down has always been the same as a few da…
One more tip for understanding emulsions: this is a link to a former discussion here on CC, it's a gem! (written by @Bill_Toge )
In addition on my reply above:
I also totally agree with @Belassi on the resveratrol.I would recommend to experiment with ferulic acid and resveratrol later on, when you are more experienced making stable emulsions, they're difficult to solubilize a…
Practically every herbal extract contains more or less electrolytes.
Are you aware that Emulsan (methyl glucose sesquistearate) is a W/O emulsifier instead of O/W? W/O emulsions need a whole different approach than O/W's, for stability …
That's also the biggest reason why I use medium/high molecular weight hyaluronic acid in serums.
It's funny that in private I use it for its viscosity and work-related I only deal with an enzyme that breaks it down (a hyaluronidase…
I don't know much about whitening ingredients, so I also haven't read about scientific studies, but I wonder are there even studies that confirm that vitamin C is a whitening ingredient at all?
They also say that about licorice, but…
Do those really make a significant difference?
Shampoos, to me, are only for cleaning and I don't mind if they contain sulfates like SLES as long as it smells good, that's about my only demand.
Expensive ingredients like panthenol …
@Dtdang , @chemicalmatt , @smok
You are all welcome! If I find something interesting, first thing I do is share it here. It's always nice if it can help more people than just myself.
Sounds great! I think it's a real talent if you can make a…
So the whole whitening hype has even made a jump to pet owners who are insecure about the colour of their pet's fur?
Personally I would already be more than happy to have a happy and healthy pet, but ok.
You already mention that dogs have a 'more fr…
Regarding synonyms. Cetyl palmitate used to be derived from the waxy substance in the head of sperm whales. A few suppliers here use names like 'synthetic cetaceum', or 'cetyl esters', like @chemicalmatt mentioned.
Microbial growth on the surface isn't uncommon, same for other anhydrous products that come in contact with water. Better be safe than sorry. I agree with @marytsiang .
I myself use 0.1% propyl paraben in lipbalms. And lipsticks, but I har…
I think she did, they even travel the world with it
Kidding aside, you're right, I hope so too. Point with people like her is they can't be reasoned with. They stubbornly believe fake internet 'doctors' and all kinds of bullsh*t site…
Not to sound cliché, but she's also anti-vaxx.
Glad I got rid of my Facebook account. With that one click there go all the 'out-of-courtesy-accepted-friendship requests-from-far away-relatives'. (in this case far away gene…
I think the figure on that price tag is only caused by that stupid brandname. What is it with you and these insanely expensive brands? :lol:
Good that you mention the danger of 'colloidal silver' ingestion, @Perry.
I know someone who drinks…
Aliacura and Alexmo Cosmetics from Germany sell a lot of Evonik/Dr. Straetmans products. Aliacura ships nearly worldwide, Alexmo only to European countries.
Good luck, I hope you'll find what you're looking for.
Erratum (my previous reply ^ )
SymSitive is not a patented ingredient by the brand Eucerin, it's the main ingredient in their Rosacea, Ultra Sensitive line (along with licorice). It's even sold by repackers like MakingCosmetics (only in bulk though,…
