@Pharma company called Biosil Technologies sells it in relatively small MOQ (~5kg)
-
Something like this?
-
@Gunther I think it’s because of production method of polysorbates (using ethylene oxide which is on the list and could be residual). I still don’t understand how in-depth products need to be investigated to be prop-65 compliant
-
Good luck - I’ve been struggling with water-thin emulsions with similar constraints (set by customer not by me).
You could try using the Tego Solve 90 as well- that one looks like it’s better for fragrance solubilizing anyway. Your emulsifier total is probably nowhere near high enough- to solubilize 15% oils you should try maybe 45% solubilizer. The alcohol was in there for a reason, you could try a crap ton of propylene glycol.You could also try pemulen tr 2 (Acrylates/C10-30 Alkyl Acrylate Crosspolymer)

@ngarayeva001 I hope so! I’m being a little cheeky (the list says no polyamide-8 so I’m using polyamide-3 for my oil gel)
-
I used the isoamyl laurate that’s not bad I just don’t have a ton of it
I do have the coco-caprylate just not sure if it’s polar enough, but best way to find out is to try it! Thanks -
I am still learning in this field but PET is about seeing a logarithmic reduction over time- not necessarily about killing everything. A USP monograph would probably contain all the details on this. Are you only testing your system against mold?
These results are presented a little differently than what I’ve seen, here’s an example of results we’ve gotten in the past.

This is something I have questions about as well (Prop 65 has a whole section about ways to interpret their rules) but here is my current understanding:
-none of the components of these preservatives are listed on Prop 65, but the issue with prop 65 is it doesn’t seem clear at what level you have to evaluate your products. For both these products formaldehyde would never appear on the label, but maybe the regulatory team has decided to play it safe and put a warning for the product knowing it releases a prop65 listed ingredient. I’ve always wondered how to handle things like Polyacrylamide (not on prop 65) that contain residual acrylamides (are on prop 65)
-there are ‘safe harbor levels‘ that give allowable concentrations (again not clear to me if this means you can skip the statement) but the concentrations they set are per day! Not really useful for a cosmetic unless you can either give a ‘recommended dose’ or prove an entire unit falls within the safe harbor level
I think it comes down to legal nonsense and how in-depth a company wants to go.

Amazon was a big outlet for our private labeling business a few years ago- what you’re seeing might not be people ripping off others but just one private label brand doing a poor job of differentiating their products for their clients.
As far as recourse for an actual design copycat I have no idea, you’d have to ask a lawyer.
-
Price range will vary depending on size you want to produce, ingredient cost, packaging you choose, if you have them do design services, label review, fulfillment of orders.
Our policy is when someone brings us a formula we don’t use it with anyone else for fear of being caught but you would be smart to have some kind of clause/agreement that outlines that they cannot distribute or use the information you provide about the formula. I’m not a lawyer so obviously best to get some legal advice here but it just seems to make sense to have a written agreement about this.
-
@Perry, thanks for clarifying!
-
If you’re using SLES why not use salt to thicken?
-
be very careful with methyl nicotinate it will absolutely redden the skin and I would say its less of a warm feeling than tingling.
I’ve heard of using zeolite or a glycerin based mask for warming but not sur how effective these are
-
The Rose water makes me think phenethyl alcohol, maybe they mislabeled it intentionally? Once I know I can’t trust the LOI my willingness to buy the product drops so fast
-
If you want to know if your formula is stable, then you need to test stability. Even if someone had made this formula before they won’t have made it with your processing so the best test is to take a sample of your own and find some conditions to test it in.
-
@lopamudra it depends on how thick you are trying to go. @Nubian is suggesting a grade of xanthan that should meet your needs:
BASF’s Rheocare XGN is a new vegan, non-GMO xanthan gum stabiliser, thickener and hair styling polymer for emulsions and surfactant-based products including oral care. This Cosmos-compliant polymer is based on 100% renewable feedstock. It combines suspending and stabilising properties with high yield value and creates elastic properties in formulations. Formulations in water are crystal-clear. Its electrolyte and ethanol tolerance is high
-
you can search for raw materials that are ecocert approvec through their website http://ap.ecocert.com/glorganic/ecocert.php?l=en.
my first thought would be some grade of xanthan gum
-
are you looking for a manufacturer to fill products or are you just looking for a packaging supplier? Glass seems like a viable option for everything other than the lip balm. They will need to know ingredients to let you know if there could be potential incompatibilities (unless you stick with glass in which case just watch out for light instability)
Things like this (https://www.sks-bottle.com/EcoCosmeticTubes.html) are another option but make sure your preservative systems are robust and monitor the filled packaging over time to watch for issues

Silver nitrate in higher concentrations leaves a lovely grey-brown stain on the skin, so even though it’s soluble I would be careful leaving it on the body too long.
-
@chickenskin grapeseed is a much drier feeling oil, it feels like it soaks into the skin whereas castor is viscous and feels like it is sitting on top of your skin
-
@Nubian- https://www.upichem.com/products/palmitamidopropyltrimonium-chloride/ https://www.upichem.com/products/isostearamide-mipa-glyceryl-laurate/
they look like they offer smaller sizes (1lb or less). hope this helps

Oilkemia 5S (Caprylic/Capric Triglyceride (and) Polyurethane-79) has been working well for me, I’ve tried playing with the Oleocraft line (Polyamide-8 or Polyamide-3 usually) but I haven’t had the same success
-
I’m not a color cosmetic formulator, but try lowering castor and increasing grapeseed? Try using just enough castor oil to disperse the oxides
