WHY DO SOME E-LIQUIDS HAVE A DIFFERENT COLOR?
The different aromas used when designing your e-liquid can first be more or less coloured. Thus, a fruit aroma will very often be lighter than a classic brown or caramel aroma. This is also the case for certain additives used such as vanillin, furaneol or ethyl vanillin. The latter brings, for example, an additional touch of “vanilla” to your liquid and enhances the taste of certain aromas. It can give a dark yellow or even brown colour to your e-liquid.
NICOTINE STRONGLY COLORS YOUR E-LIQUIDS
By highlighting certain colours, the nicotine that may be present in your e-liquid also contributes to darkening it. The higher your e-liquid will be dosed in nicotine, the more chances there will be for it to be dark. You will almost always notice differences in the same flavour between a liquid without nicotine and the same nicotine. Liquids without nicotine are mostly transparent, unlike those with high doses (16 or 18mg for example), which are often very dark.
OXIDATION, UV AND HEAT
The change in colour of an e-liquid can also be explained by exposure to UV rays, prolonged contact with air (oxidation) or a rise in the temperature of the liquid. The colour variations are moreover more consequent on the liquids whose rate of nicotine is important. However, it is essential to emphasize that this colour change in no way alters the taste and organoleptic properties of the aromas.
DIFFERENT COLOR BETWEEN MY BOTTLE AND MY CLEAROMISER?
Finally, if the colour of your liquid included in your tank differs from that present in its original bottle, this means that your resistance is at the end of its life and degrades the liquid introduced into your clearomiser. Change the resistance or your clearomiser as soon as possible if the latter is not removable.
