  Formulation pressed powder

  Posted by Hamed on November 22, 2015 at 8:52 pm

  We are trying to formulate a 2-way pressed powder (compact powder) with an acceptable water and oil absorption and sun protection…

  We tried different formulate however we could not find every raw material especially the ones which is so specific or new…

  We mostly use the drug grade materials..

  We tried this formulates.. but there is always some problems.we can’t find out what’s is exactly..

  I change different parameters but every time there is at least one problem…

  (Our customers don’t care what we use or how we formulate… they just care about coverage and good feeling of wearing the powder)

  
  

  Talc

  Magnesium strearate

  zinc stearate

  titanium dioxide

  Zinc oxide

  calcium carbonate

  *lanolin and some fatty esters

  *benzylalcoholI

  *bismuth oxycholride

  *nailon 12

  *Isostearic acid

  Iron oxides

  Personally I think, we could not chose a right binder for the materials but it doesn’t explain not having good absorbent of water 

  ** I use them alone and even a combination of them but still the problem exist?!

  I thought we have to use “emulsion binders” in range of 7% up to 10%

  Esters /Glycerol /….

  So I did not used other binders in the formulation

  2-way pressed powders were only made possible when hydrophobic powder treatments were invented. If you can’t get hydrophobically treated powders, you will have to make them yourself before you can make a 2-way cake. If you can’t get the chemicals (reactive silicones) to make the powders, you will need to find another way to get regular silicone onto your powders evenly.

  Well, for starters, you have 113% of total ingredients in your formula.

  The ITT is a powder treatment patented by KOBO. It will be completely ineffective on it’s own. If you can’t get treated powders, or figure out what to do from published patents, you’re going to need to hire a consultant.
