  Which

  This is a cationic emulsion.

  2% BTMS 25

  10% glycerin

  4% petrolatum

  3% mineral oil

  0.05% FO

  0.1% cationic guar (may or may not be used)

  pH 4-4.5

  Package: 500ml flip top cap bottle

  1. What microorganisms are most likely to contaminate this?

  2. Which preservative would be stronger for this? Specially for yeast and mold.

  1.5ppm CMI MI+ 0.02% formalin or just 1% phenoxy ethanol or just 0.6% benzoyl alcohol?

  A patent from L’Oreal had used only 1% phenoxy ethanol as preservative for a cationic emulsion.

  Another patent had used only 0.6% benzoyl alcohol for an almost similar cationic emulsion?
