The viscosity (consistency) of some oils are just naturally thicker while most are thinner and watery-like. For example, citrus oils are very thin but root oils are thicker. From a chemistry perspective, the lighter/smaller molecules (such as those that make up citrus oils) are thinner, and heavier/larger molecules (such as those that make up root oils) are thicker.
Benzoin Liquid Resin is extremely viscous, and therefore more difficult to use. With time it may solidify. Gently warming the oil in the hands before use may help (takes patience!), or you may need to warm in a water bath.
