Please Note: Due to a substantial increase in the wholesale price of Natragem EW we have had to increase the selling price of this ingredient by a significant amount. We endeavour always to keep our prices as low as possible but when the price to us increases so much we have no option but to cover the increase.
Natragem Ew is a highly efficient and effective 100% natural emulsifier. It can create pourable lotions to high viscosity creams which are non-whitening* on the skin and have great sensory benefits. It is as mild as water on the skin.
* In our trials we actually found the emulsifier to be particularly problematic in regard to micro-foaming (the whitening effect some creams display when rubbed into the skin). However when we combined Natragem EW with a low HLB emulsifier (we used Glyceryl Stearate) whitening was significantly reduced. Although we have not undertaken exhaustive tests to derive the ideal ratio to mitigate soaping completely, a ratio of 3:1 or 4:1 (Natragem EW: Glyceryl Stearate worked well.
Rather than increase the amount of emulsifier(s) to make a cream thicker (which seems to be a common practice) use fatty alcohols such as cetyl alcohol to increase the viscosity of the cream.
Example: for a 15% oil content we would recommend
15% Oils / Esters
3.5% Natragem EW
1% Glyceryl Stearate
1% Cetyl Alcohol (2% for a thicker cream)
INCI Glyceryl Stearate (and) Polyglyceryl-6 Palmitate/ Succinate (and) Cetearyl Alcohol
Appearance: Pale yellow flakes
Formulation: Add to heated oil phase
Recommended usage: 3.5%-5% for 12 -15% oil content.
Tips: Incompatible with Gluconolactone.
