Thanks for the info

Belassi-why not use 3A alcohol denatured with brucine-touted as most bitter denaturant known? Dont know tox so would check it out .
-
The only place i used 3 roll mills (304 or 316 stainless steel) is for bar soaps etc—do not understand why you need for lipsticks/deodorants???
-
K-sorbate is active at 5-5.5 PH the Pka of sorbic acid and it discolors (violet/blue) in storage at 50C after two weeks equivalent to one year at ambient RT.I would choose another preservative for your system.
-
Yes as far as I know
-
What about when you do it as there is no obvious reaction
-
Sorbitol esters is not an INCI name and as written in formula does not define HLB for emulsion:which is also low in listing.Needs a nonionic polymer emusifier because (as above Bill Toge comment) ammonium salt could mean cationic emulsifier.Respectfully the formula is not well described or designed.But if you have to fix it use combination of Xanthan gum and Slerotium gum as stabilizer.
-
Have not used it, but Looks like you need an emulsion stabilizer—xanthan gum or a polymer -I think they say that in Data Sheet.
-
Thixin R should work
-
why do a dilution to lower viscosity particularly with C-SF-2.Just lower the polymer level to decrease viscosity.
-
In reality, it all comes down to the claims whether FDA considers product drug or cosmetic.
-
Would not mix up situation with makeup removal particularly around eyes.But we have made cleansing shower gels with superfatting oils which work fine depending upon your market audience.So do it and try a panel test.
-
great answer and how true
-
You can use Willow Bark but strictly as a cosmetic:the drug part comes into play when you make a drug claim.
-
got it —good luck —guess as Bob suggested you could try D4 or D5
-
problem with silicones is they do mt dry very fast,Why don’t you make an aerosol spray?
-
WHY not use a mixture of ZnO and TiO2 which are approved.Critical wavelength for UVA (370nm) is easily achieved using relatively low levels of the combination?
-
We have made similar systems using combination of Ultrez 10 and xanthan gum in a 70:30 ratio and omitted eo adducts such as polysorbate 20.
-
Why don’t you try an aerosol for drying if you are happy with formula the way it is.if it runs add a small amount of rheology modifier for pseudoplasticiity?
-
We have had several people over the last twenty or so years with similar problems with contract packagers.many go out of business and the marketed formula for the product goes with them.Too bad but it happens.
-
i don’t think 5% etoh will passs USP 51 even at low PH.Suggest geoguard Ultra which should pass at 1-2% and buffer PH.
-
There are no legal rights until a provisional (at the least is filed with USPTO.) .This must be prior to public disclosure:this is the crux of custom formulation ie to provide a contract to the effect the client owns the formula and process upon completion.The client can file as per the foregoing if he/she wishes prior to contacting a Packager or make some agreement with the latter.

see claim 1 part 3 -
talc in bars makes soap short (similar to excess salt) adding to drying effect-too much causes cracking—maltodextrin plasticizes -balance needed
-
TRUE—The sysneresis is likely coming from high glycerin.You can replace some with/ or all with talc or maltdextrin
