Paraffin Wax - Fully Refined (Candle Making)

Not necessarily. Many waxy or fatty ingredients mainly add body, slip or structure; use a proper emulsifier when the formula contains both oil and water unless the exact material is designed to emulsify.

It can increase structure or body in many systems, but final viscosity also depends on the emulsifier, oil phase, water phase and cooling profile.

Excess structurant can raise drag, heaviness or a waxy after-feel. Reduce it and rebalance the oil phase rather than judging thickness alone.

Often yes when compatible with the other oils and waxes. Test hardness, payoff, sweating and temperature stability in the final packaging.

Solid waxy grades generally need controlled melting in a compatible heated phase. Avoid unnecessary overheating and follow the supplier's processing guidance.

Not reliably. Melting point, crystal structure and sensory feel vary, so substitutions should be trialled rather than made only by weight.

Graininess can come from crystallization, cooling rate or interactions among waxes and butters. Adjust the heat/cool process and composition, then retest.

Yes. A firmer or more crystalline matrix can change how quickly fragrance is released, so evaluate scent in the finished product.

Check melt behaviour, cooling, texture, sweating, shrinkage, stability and package compatibility in a pilot batch.
