Product introduction

Specification

1. Method and Application: Paraffin oil or liquid paraffin from the fractionation products are mineral oil. High purity products can be used for medicine and cosmetics, low-level impurities in the product contained high, if mixed with food, harmful. Aging meters of the surface dull, adding paraffin, liquid paraffin or other mineral oils can make the surface smooth and beautiful mixed, but it masks the aging meters mycotoxins that may exist.

2. Operation: Take half cup of rice on the sample size, adding more than 70 ℃ hot water to nearly full at the sample cup, stir gently with a clean toothpick than 30 seconds, put it aside for a moment the solution temperature decreased to below 50 ℃ (melting point of paraffin wax is 50 ℃ ~ 65 ℃).

3. Results judgment: If the sample mixed with paraffin, on the surface due to minute oil droplets, as the temperature decreases and the extension of time liquid paraffin oil beads together to increase the solid paraffin oil beads will form white flakes floating in the liquid surface.

4. Introduction: Speed ​​measured in a liquid paraffin box control solution, necessary to do controlled experiments. Found positive samples can be sent to the laboratory for further verification.
