Geoguard ultra would be better.Use at 1% .

You can conduct Half Head studies if you have access to a salon for Lather wet/dry comb softness etc versus a commercial blinded benchmark. Don”t forget USP 51 for preservation.

The weight ratio of TEA/NAOH is 3.73: so on a weight basis for 0.5 ounces of NAOH use 1,87 ounces of TEA.

This link will help find the orderone http://ordenone.belle-aire.com/what-is-ordenone.We have used it with DMI with success.

I have had the same experience with polypeptides in cosmetics-good consumer feedback followed by high purchase-re-purchase.

You can adjust Ph to 4-5 and use parabens —phenoxyethanol/ethyl hexyly/glycerine.Benzoic acid will work also. Avoid preservatives containing an amino group/s.
-
DGME used mostly in cleaners if you are using it as a solvent for DHA switch to DMI (low odor Grant Ind) which may give slight odor but easily masked with Oderone.

The best way to support a claim for your finished product (cosmetic) is via a test either in-vitro or in vivo:small panel tests of 30 people will tell you consumer perceived attributes while in-vitro such as Franz cell for skin penetration will support the science.Most often one has to do both.
-
Ammonia is released at Ph 7 and above so at 5 -6 you can use BA—-Phenoxyethanol parabens and so on.
-
You are right as we did this!Contact supplier and request preservative you want in your ALS to be the same as you are using in final product.Ask for designation on drums you buy i.e. TRade Name. JSJ special.

What is in the water in addition to HEC as chemist 77 said it should go in easily.Who is your supplier?
-
I follow the practical cycle as outlined-your number 2
The so called ideal makes me laugh. -
sorry the name is Ernie Brina ebrina@steronpackaging.com

STERON PACKAGING-Ernie Steron cell 908-804-0774. have used many times for small to large runs.

Total hours 24—-12 hours overnight in freezer.Take out and stand w/o shaking at ambient RT.Should come back to normal within 12 hours (if stable usually comes back in 6-8.

Change emulsifier and thickener to Ultrez 10—add to water use 1 percent with .3 xanthan gum—-combine both phases at 70C-cool to 50C and add 1 percent triethanolamine to thicken and form cream.
-
What Carbomer are you using and what neutralizer?
-
@Lainee Yes i would remove particularly cabosil as it has no reason for being and both may be your grit problem.I dont think homogenizer will do it.You need to mix in a ball mill to grind particles similar to paint coatings:using Hegerman grind gauge until smooth.
-
Accelerated stability you can do for two year shelf life: do four weeks at 50C and monitor ph viscosity color odor phase stability.also do 6 cycles of freeze/thaw and hold a sample at ambient temp 21C and monitor after 6-months -1 and 2 years.We do this routinely on all products we market and we have marketed hundreds without a recall.For us it is a verifiable science.All you need is a freezer and oven.You should do preservation USP 51-400USD and when you can do RIPT for safety(as i explained above) or at least run occulsive patch test for primary skin irritation.
-
Good
-
NO Looks like they did not: ask why they didn’t do preservation USP 51 as needed by your company prior to marketing.Also they should do viscosity.Are temperature and Time listed on certificate?
-
could be Cabosil
-
Totally agree!

i think you are saying or want to say heat is inversely proportional to the % strength of H2O2 to provide lightening with minimal damage during use.In other words the higher the temp the less concentrated the H2O2 needed to lighten with minimal damage.You are a salon guy what about time ?
