Any UV lamp recommendations? We have a similar system but our plate counts are still too high

I would say there are other things you can do first that are lest costly/ good indicators of stability. Are you already monitoring samples in stability chambers over time? Do you use freeze/thaw testing?
The centrifuge might be able to tell you about the emulsion strength, but the ovens/fridge are nice so you can see how your product will fare in some real-life temperatures over time.

We’re going off our suppliers statement of 30% CBD added to MCT oil, and calculating the mg per the whole container. It’s very pricey, like @Gene mentioned.
-
Haha I appreciate the responses! To me this all makes sense, the cruelty-free is just one example. I am trying to cut down the amount of repeat requests we get in R&D when the questions should be handled by regulatory/legal team so I was wondering if there was anywhere I could point them other than FDA website and 21 CFR

Not the exact same, but I’ve used lipogard (INCI Squalane, Tocopheryl Acetate, Ubiquinone) and have also seen the orange precipitate straight in the supplier’s bottle. Their tech sheet has this to say
-
Also use sepiplus 400, it’s not my favorite but that polyisobutene is supposed to give that rich silicone feel. I recently used it as my only emulsifier with ~7% oil and added in oil phase and the end result looks a little greasy/gluey, but it does feel relatively nice and absorb quickly.

Not sure where you’re looking, but nobody is interested in buying d-ascorbic acidb(as far as I know). So the general ‘ascorbic acid’ refers to LAA.

I would take a look at some sites where you can find cosmetic formulas and see what procedures they follow to get started. It’s also going to be easier if you have a goal product in mind- do you want to make lotions, serums, pomades, cleansers??
Perry has links to where you can find cosmetic formulas to start, you can also look around on the forum and see what’s been posted here.
Answers to your questions are going to depend on the ingredients you have/ want to work with -
Where are you located/ trying to sell?
-
It might work, I just feel I should point out in the US this is not a cosmetic, it’s a medical device
-
oh a pomade!
try carnauba closer to 3% first
cut beeswax down to 10%, replace that with petrolatum
I would say try those two things, or just one at a time, and compare to your previous attempts -
Is it bad I don’t know what briolin is?.. The wax percents seem really high for ceresin, beeswax, and even carnauba. Honestly try cutting them each down by almost half and see what consistency you get then
-
I don’t know about color cosmetic formulating, you can search if you have a specific INCI in mind 🙂
http://www.ecocert.com/en/approved-raw-materials/index.htmlIf you don’t need the Ecocert approval just something along those lines, plenty of starches will work as film formers. I’ve used this one https://www.grainprocessing.com/starches/facial-masks-cleansers.html
but beware of the MOQ.. -
@CarbopolUltrez, if I were you I would make documenting my best friend. Start tracking how much overnighting materials costs if you’re given only a week to source, write down when you find alternatives that could have been more cost effective. If you hear about product complaints write them down too and how long it took to be noticed. Because I’m at a small company I’ve been given a fair amount of voice despite being new. If you can show the issues you currently face and how resolutions would save company money, maybe that will help buy you time? I like the ‘as is’ contract idea, but it’s hard at first to convince higher ups that you want to change processes outside of R&D

Was there any water loss for the product that was in the 45?
-
You can get sodium phytate, haven’t seen a calcium version.
-
@CarbopolUltrez …. are you me? In a very similar situation and yes the pace is fast. There are times where I appreciate it, especially being in a smaller company- lets me see and do much more than I would as a tech in a big pond. I’m getting exposed to all kinds of ingredients/formula challenges and constraints that come from ‘real world’ issues like MOQ and production capability. I would appreciate being able to spend more time on the science, but for a starting experience I think exposure is really valuable and I have less fear about screwing up. Message me anytime and we can rant about impossible deadlines!

If you’re just looking for new marketing angles, we often use Pentavitin which has Saccharide Isomerate or Prodew 600 which has natural moisturizing factor amino acids and betaine.
-
haha no they would definitely not spare the money. I think I misused the terminology, it’s not an exact reverse engineer, they just want something similar so I’m going by LOI and knowledge of the ingredients.
-
Maybe they are using the dimethicone crosspolymer and the hydrogenated polyisobutene to suspend and physically separate the phases? I don’t have experience in color cosmetics so that’s just my guess
-
Yeah that’s true, on the product I have though it does actually list the numbers in the ingredients list:
-
What’s your source here?
Also what do you think surfactants are? (you should look up surfactants vs emulsifiers)
Is your full formula just those two materials? because I would be a little cautious with that homemade lotion if you’re not adding any preservatives. -
Is this just for your personal use? I don’t really know if hair growth falls under cosmetic or drug category, and I wouldn’t expect very substantial results with extracts and oils that are probably not standardized.
That said, a couple products that are used for these types of requests:
Pisum Sativum (Pea) Sprout Extract
Vitis Vinifera Fruit Meristem Cell Culture (and) Hydrolyzed Eruca Sativa Leaf (and) Hydrolyzed Walnut Extract
Humulus Lupulus (Hops) Extract
Capsicum Frutescens Fruit Extract
Larix Europaea Wood Extractall I did was search “hair growth” on UL prospector.

I think Hemp has a very specific definition in the farm bill as containing less than 0.3% THC content. (Industrial Hemp is the term) see here
https://www.colorado.gov/pacific/agplants/industrial-hempAlso attached more legalese if people are interested.
it’s still pretty unclear to me at least the direction of hemp-based products in general, but people are making products anyway.
