There is a probably a residual solvent used in the manufacturing process that is causing the prop 65 concern.
@Newtoformulating I don’t have much experience in that type of product, so not sure, sorry!
-
@Paprik correct I guess I was just focused on the glyceryl stearate part, not self emulsifying. but nonetheless I would still consider gms and gms se emulsifiers
-
What would you consider it?
You even classified it as an emulsifier
-
@ngarayeva001 GMS (glyceryl monostearate) is an emulsifier
-
I would request a prop 65 statement from the supplier. If the chemical in it that has the prop 65 warning has any safe harbor limits, you may be able to use it without having to include a warning on your label.

We buy from prinova

FDA needing tighter regulations on cosmetics vs. the regulations being sufficient as they are now
How many times do you hear people say, like the good old EWG, that cosmetics aren’t regulated and that the FDA needs to do more to ensure cosmetic safety?
For example (copied from safecosmetics.org) -
The United States has much to learn from the EU example. The EU Cosmetics Directive (76/768/EEC) was adopted in January 2003 and most recently revised in 2013. The EU law bans 1,328 chemicals from cosmetics that are known or suspected to cause cancer, genetic mutation, reproductive harm or birth defects. In comparison, the U.S. FDA has only banned or restricted 11 chemicals from cosmetics. Unlike the United States, EU law requires pre-market safety assessments of cosmetics, mandatory registration of cosmetic products, government authorization for the use of nanomaterials and prohibits animal testing for cosmetic purposes

what pH are you aiming for?

Try avalure flex 6 from lubrizol. I’ve formulated bb/cc creams and mineral based suncreens with it

silicones can help with the glossiness and maybe try glycol distearate if you want something more pearlescent - I know that can be used for rinse out conditioners but I’m not sure if that is suitable for leave-in products
-
I was researching for something else and came across dowsil 9701 cosmetic powder (Dimethicone/Vinyl Dimethicone
Crosspolymer (and) Silica) and remembered reading your post earlier. I haven’t used it before and not sure if there is a more favorable silicone, but the picture on the marketing sell sheet looks promising for filling lines (and yes, I know its not best practice to go off suppliers marketing data alone) but maybe you’ll see some benefit in using that product or something similar -
I’m not familiar with that but purell has a foaming alcohol hand sanitizer with peg-12 dimethicone so that may work
-
@andraous Awhile back I used bis-peg-10 dimethicone in a foaming 70% alcohol based hand sanitizer, although it did leave a slightly tacky feeling on the hands but if I remember right it foamed pretty well.
-
@Pharma and @Bill_Toge thanks for the recommendations, I will test those out.
@Graillotion right now I am just using samples from the supplier, although they only send such a small sample size because it is an expensive material, maybe 30 g at most. I have all of those ingredients that you mentioned so I think I’m going to try something similar. I have only been able to make a few formula variations because I’m so limited with the L22

One of our customers has asked us to duplicate K5 diabetic skin care nerve pain formula, not real familiar with it but apparently its a hot seller? I included the formula below if your curious what’s in it - seems to be a lot of vitamins and may just be for marketing. Anyways, the active in it is zinc acetate but it also seems it may contain a fair amount of Palmitoylethanolamide and when I searched that ingredient I found some literature regarding the treatment of pain. I haven’t really read through them yet but might be something to look into.

also, I don’t think triclosan is allowed to be claimed any more as an anti-bacterial in the US
-
benzalkonium chloride, 0.10-0.15% is the level allowed per the otc monograph

@chickenskin I’ve used either Ultrez 30, Ultrez 20 or Pemulen TR-2 NF with the lidocaine HCL. Also paired with simugel NS or simugel FL. I used salonpas lidocaine products as a reference

@MarkBroussard it was mentioned in the webinar that an oil soluble preservative will not be effective if water was somehow introduced to the product, unless I misunderstood what they were saying
-
@PhilGeis These products are for use on babies and kids for chapped, irritated skin. The stick formulation could likely be used around the nose/mouth area so I think it would be likely for contamination to occur from snot or saliva. Personally I would dry the area before applying, but that doesn’t mean everyone will do it that way so I would think that would introduce a possibility for microorganisms to grow?
The jar products could just be contamination from repeatedly dipping in fingers that may potentially be dirty but I’m not sure what potential for growth there is. We just sent these out for challenge testing this week - which also was mentioned in the video that challenge testing is not necessary for anhydrous powders so would that hold true for an anhydrous balm? Is there a better type of testing to do to ensure micro safety?
-
@Zara yes, adjust pH first and then viscosity
-
@naturalchemist you can add propylene glycol to help with freeze thaw stability. I was having this issue with a conditioner I was working on awhile back. Your water could be freezing and causing the polymer to agglomerate, so adding the propylene glycol will help suppress the water from freezing
-
I would say your thickener is not so much a thickener as it is a stabilizer. In my experience using it, I haven’t seen a huge increase in viscosity when adding it to my formulas but maybe it is just formula dependent?
-
They also have Hydramol™ PGPD ester which they say is supposed to make it easier to rinse off oil-based systems with water

Lubrizol has oilkemia 5s
