Liber has developed our own proprietary nicotine liquid formula which is manufactured with pharmaceutical quality ingredients in a GMP-certified facility. The nicotine liquid in your Q Cartridge is comprised of:

• Propylene glycol (PG) –  an odourless and colourless compound that is less viscous than VG. PG carries flavour more effectively than VG, and also provides the ‘throat hit’ component of the e-liquid. Our PG is manufactured to US or European Pharmacopeia (USP/EP) grade.
• Vegetable glycerin (VG) – a is a colourless, viscous organic compound that acts as a diluent for the nicotine and serves as a base for our flavours. VG is found in many food, cosmetic, and pharmaceutical products where is is classified as a GRAS (Generally Recognised as Safe) ingredient. Our VG is manufactured to US or European Pharmacopeia (USP/EP) grade.
• Flavours – our flavours are manufactured from molecularly defined ingredients (single chemical constituents) that are compounded into flavour concentrates and are subjected to a rigid quality verification process prior to formulation. All of our flavour compounds have undergone a Toxicological Risk Assessment (TRA) and are manufactured in an ISO cleanroom environment.
• Nicotine salt – the active ingredient in our nicotine liquids. Our nicotine is manufactured in Switzerland under full pharmaceutical cGMP. Nicotine is not a carcinogen, and while it is not linked to cancer or cardio-vascular disease, it should be noted that nicotine is an addictive substance.
