When selecting materials, Glass (Type III or Borosilicate) is the industry standard for the primary container because it is chemically inert, preventing reactions with fragrance oils. For the outer box, prioritize high-density specialty paper (250-400gsm) or rigid cardboard to provide structural protection. Ensure that any plastic components, such as dip tubes or caps, are made of PP (Polypropylene) or Surlyn, as these materials offer superior chemical resistance against alcohol-based formulations.
