There are cosmetic beads that will release color when pressure breaks them open, several suppliers offer them (Givaudan, Sanddream, Salvona)
ex.
MicroBead™ ColorFx (White to Yellow)We used them in a product where a customer wanted a ‘shade matching’ cream, ie you stop rubbing when you hit the desired color

Yeah legal or not that’s a definite Yikes. It’s sad because I know there are charities that try to use the same concept to provide women in shelters access to cosmetics, but really the sterilization /safety is too difficult I think. Next best thing is just returning the packaging and getting it refilled
-
I have very weak knowledge of microbio, but the fact they only show up at the edges is interesting, I don’t think growth would occur that way (unless the edges are holding more moisture?)
-
That’s more of a financial/legal question. I can say we typically sell our formulas anywhere from $6,000-15,000, but there are plenty of ways to handle it.
Our price is for a fully finished, tested formula that has shown no issues in safety or stability. Make sure you outline what you are selling carefully.

The main two tests you could start with are Total plate count (USP or AOAC methods are well known and trusted), and heavy metal content. Most analytical labs will be able to do these test no problem and tests themselves don’t take more than 2-5 days. A google search for those tests + ‘cosmetic testing lab’ should give you plenty of options
Here’s a lab I’ve used https://www.npal.com/services ( just check that the whatever lab you choose has some accreditation such as ISO)

Sodium Benzoate and Potassium sorbate are both used in food, but the pH has to be low (5.5 or lower is the typical recommendation). They have a maximum safe use limit set by CIR, and I would take extra precaution formulating to avoid any potential issues with infants. No customer will be more dangerous than a mom who thinks your product has harmed their child

@Pharma slight tangent but what do you think of the Skin Chakra site/the formulations?Just found her last week and I didn’t see any immediate red flags

you say tincture- are you drinking this? for cream or lotion you can add a masking agent, i don’t know what is available in turkey but something like :
DeoPlex® Natural Deodorant

I’m sure you could do it with just extra propanediol and avoid alcohol

MemberMarch 5, 2020 at 3:40 pm in reply to: Using an innovative ingredient not listed on CIRIs this a new material never used in any other products (skin care or otherwise) that you could pull some data from? You could also try to partner with an ingredient supplier and have them do some of the heavy lifting.
CPTC labs will do custom experiments, and they have already established tests including Ames Mutagenicity Testing, in vitro toxicology, skin sensitization.But like Perry said I’d imagine the cost to be pretty high

We use book-page numbers for lab use, and then 6 digit codes (three letters three numbers) for full production. It’s whatever system will work best for your needs. If you’re inputting any of this into some software, leaving spaces is generally a bad idea for naming things, so do underscores, dashes, zeroes,etc.

You can make a minimum risk repellent that doesn’t require registration, would that not be a good fit?Essential oils have to be listed individually in cosmetics as far as I know, Fragrance usually relates to having a laundry list of individually selected molecules to create a smell
Determining product classification depends on your claims, but if you read warning letters you’ll see that website reviews/customer testimonials are also often considered, or even singular ingredients that have a well-known purpose.
I am not a fan of following rules just because they are rules, but these exist to let consumers make informed choices about what they buy, and the more ‘active’ you want something to be, the greater risk you run of endangering someone- registration/testing guidelines can mitigate harm

1,3 is used. “Butylene glycol is prepared by catalytic hydrogenation of aldol in the presence of hydrogen and a hydrogenation catalyst.”
1,4 is for industrial purposes or for recreational drug abuse…I won’t ask why you are asking

MemberMarch 3, 2020 at 5:11 pm in reply to: 1st Post - Shampoo solid-to-liquid Recipe Feedbackhttps://www.wetnwildbeauty.com/personal-best-exfoliating-cleansing-balls.html here’s one version
This formula is from Univar for a loose flowing cleansing powder. The second formula is a moisturizer that looks like wet sand but could also be a source of inspiration (i recognize the materials here are not all exactly green but that might be one of your issues).I’m sharing these but I do agree with some of the other posters this is not a very easy starting point

Solvay also has it ANTAROX® F 127 NF
Haven’t bought this specific material before but these suppliers are up to snuff.

Sodium bicarb is a much weaker base, it will likely not perform the same. TEA is also weaker than NaOH but not as bad as bicarb so maybe that is your middle ground
-
I’ve seen that mentioned before but never seen an article cited. Could try contacting the company or Schulke to ask for more information- maybe their studies could give extra insight.
Any of us can guess but I think you won’t be able to tell without challenge testing your specific system. Surfactants (surface-active-agents) affect surface tension which could help mitigate some contamination issues even if the preservative isn’t performing as well. -

I think Aerosil 200 would not be your best choice
1) I imagine it would take a decent amount and you could find other thickeners cheaper
2) the particle size is so small you would need to wear a respirator when dealing with large quantity (unless you have some nice equipment for incorporating)Thickener options include:
-gums (if your shampoo is not anionic you could use cationic guar)
definitely cheap but some of the sensory profiles can be unpleasant
-Ritathix DOE (PEG-120 Methyl Glucose Dioleate, Methyl Gluceth-10)
-Acrylates Copolymer and other acrylates are usually cheap, but can have issues in certain high salt systems -
1) looks like the bubbling is just coming from surfactants- so Potassium Cocoyl Glycinate, Coco-Betaine, Capryl/Capramidopropyl Betaine (think that is it in this formula)
2) yes all those glycols are multipurpose- solvents, penetration enhancers, preservatives or preservative boosters (they reduce the water activity)The oils are held in with the combination of surfactants, and the viscosity enhancers ( the clays, the gums, the polymeric thickener)- I don’t know if the glycols contribute much on top of that, there was one article cited on the forum suggesting including glycols could actually destabilize emulsions.

What makes you think lotions could damage the face?
There is no standard difference. For body lotion you usually lessen ‘actives’ because you have to provide a larger size and you want to keep cost down

If it came in a shelf-ready display case, sometimes the ingredients are listed on there instead (I think they cover it at the very bottom of that guide). However I have been in CVS and seen no case, no ingredient label anywhere so it’s not unheard of.
