Not to sound preachy, but I would say a marketing stance like ‘natural’ should be secondary to safety/quality of the product. And there is so much misinformation about what ‘natural’ products are- parabens can be found in nature! The synthetic forms are identical and are produced in a controlled manner.
I often wonder if the people who love the ‘natural’ positioning of products ever think about the sustainability of harvesting potentially rare or indigenous plants and the possible effects on the environment long term. Are natural extracts and oils tested as rigorously and consistently as synthetic products? My personal opinion is that is unlikely.

2 H2O2 —UV/heat/time-> 2 H2O + O2
Hydrogen peroxide is a weak acid, that’s why the solution becomes acidic. This is more of a general chemistry question though that you could easily learn more about by googling

Do you have alcohol in your mouthwash and how much

the top post of the forum is where people can promote their businesses/services, I only saw one in UK http://www.jlpcosmetics.com/.
You could also go the route of hiring formulators, buying the formula itself, and then contracting but I think that would be slightly out of your budget for now. There’s also always private labeling, if you want to just test the water and see what kinds of products do well while still putting a brand name out there (that’s definitely the cheapest option but you’ll have the least freedom)

Had a thought last night about looking for instruments that could step up our formulation tech instead (i.e ability to make liposomes easily)
Anyone ever worked with something like this?
https://healthcare.evonik.com/product/health-care/downloads/evonik-lipex-extruder-brochure.pdfMaybe there is something else along these lines I should be considering?

I think it’s going to be a balance of formula and the actuator/packaging.
I used Pemulen TR2 in a sprayable emulsion that has done…okay. Stability has held up but the packaging is not ideal and the product spurts a bit. Glyceryl oleate citrate has never worked for me, I do not know how to tame that beast.
How large is your oil phase and what emulsifiers have you tried?

We are almost entirely skincare, haircare is rare for us. I figure TEWL would be worth something. I think the corporate team has a idea in their mind about ‘R&D equipment’ that will not align well with what I present, and they typically don’t like when people ruin their ideas..
@RDchemist15 oh I’d absolutely love to get HPLC but honestly I wouldn’t want to test any finished goods with it, I imagine the signal would be wild. Also I think they would balk at the price, I’ll be surprised if they even consider anything close to 30k
-
shouldn’t be much different to add, not sure how stability is affected. Unless you are buying ‘water-soluble’ cannabis compounds (which I think are bull), then the oil phase or on cooldown if the amount is small are the best bet
-
I know hydrogen peroxide is better at killing biofilms, but I think day-to-day maintenance with IPA would go a long way.
-
I think you are combining two different ideas. There are some pigments that would be UV sensitive (so color changing in the sun) or thermal. The heat from your body would likely change the product color before the heat from the sun would.
There are also products that change color based on pH like bil says. Those can be used on skin if done carefully, I’m not sure about the others. -
Yep our CBD product claims are pretty much “here’s the product…with CBD” nothing about effect

Here is the ingredient list for Fixodent
Calcium/Zinc PVM/MA, Mineral Oil, Petrolatum, Cellulose Gum, Silica, Red 27 Lake

Off the top of my head:
Phenethyl alcohol (often used with a glycol) - smells slightly like rose
p-anisic acid is marketed as a scent masker but the same concept
-
Are the ingredients you are using from the same lot when you make smaller batches vs large?
-
I wouldn’t think so as long as the microwave and the stove top are heating the water to the same temperature
-
@Aanchal I see. CAPB and SLES are supposed to be a match like peanut butter and jelly so maybe you just need some minor adjustments.
The citric acid is there partially as secondary chelator and to keep the pH ~7. In that specific formula it was <0.1%.
I’m not sure how much chelator is needed, I think it would depend on the other ingredients and the metal burden. The theoretical calculation is probably too involved and might not carry through perfectly to application. my guess is that standard 0.1% is more than enough, without testing for free heavy metals you’re really just looking for the chelators to help formula stability

I don’t make hair products but I imgaine you should do what we do for hot-process skincare: weigh out the final container you mix in and hold onto that number. You should also know the weight of your batch size (ex 300g batch). After mixing a little less than your standard time (say 5 minutes) you should get the weight of the container+batch. If it doesn’t add up to what you expect you add the water needed to get the proper weight. then mix for another minute or two and you should get a more consistent product.
Ex. a 400g container and a 300g batch
if you weigh the batch and container at the end and it doesn’t weigh 700g (say 690g), add 10g of water and mix it in before pouring. Hope that makes sense! -
What is the mixer machine made of?
-
I wouldn’t advise a 50% solution unless you make it pretty slowly. The reaction of NAOH dissolving is very exothermic so if you dump all the required base in at once you’ll get some steaming hot and strongly caustic solution.
We make 20 or 25% typically and it doesn’t contribute much water if the only acid is a carbomer.
-
Aside from every other obvious issue, can’t claim love as an ingredient (fda has explicitly said):
I’m a little in shock this is a real product
-
@Aanchal So it’s like Perry is saying, you are doing the traditional surfactant +salt to thicken and EDTA will contribute to that. You might have to reduce salt (cut down on your ingredient w/ salt) or increase SLES
I’ve made one basic cleanser a while ago, base was something like:
Water qs
Tetrasodium EDTA 0.05
Sodium Methyl Cocoyl Taurate 30% 5
SLES 70% 15
Citric acid qs
Salt 2.5
preservatives/ marketing fluff qsYou can do a salt-curve analysis to find where your formula is thickest
-
Perry has some courses online: https://chemistscorner.com/products/
I’ve heard this blog (https://www.swiftcraftymonkey.blog/) has some decent information
Like @ngarayeva001 the books/resources can only do so much. You can come up with a formula idea, find ingredients and equipment you can afford, and then begin formulating and testing. Hands on experience will give you more information and insight
-
are you saying it doesn’t foam at all?
As far as sticks to surface I wouldn’t expect it to, it’s a shampoo and is meant to wash off easily. Is it too runny?Unless you are using this same day you need a preservative by the way
-
Here are the two I could find on my computer easily, I’ll search around for more. It’s got use as a penetration enhancer, anti-inflammatory, skin lightener, and it’s a terpene which I think are just a wild class of molecules.
-
I count bisabolol as an extract, you can buy natural bisabolol sourced from the Brazilian Candeia tree. (I really like that molecule, there’s tons of interesting reading on it, not just to calm inflammation).
I think Perry and Zink both have good points. From a skeptical point of view, I’d believe most suppliers are selling glycerin and water that once touched a plant leaf for a brief moment. Companies that offer standardized extracts I have a more optimistic view of, but it comes down to how much people are willing to pay.
