Updated usage recommendations

• Typical dosages : 0.5–2% as a base note or according to its role in the formula.
• Suggested mixing :
  heat slightly (up to 35–40 °C) and use suitable vehicles such as DPG or benzyl benzoate to obtain a homogeneous mixture.
  Maceration in ethanol (96–100%) followed by filtration for use in alcohol-based perfumes is also possible.
• Avoid poorly miscible solvents , such as triacetin, which do not guarantee good solubility of dense and resinous absolutes.
• Ideal pairings : bergamot, lavender, patchouli, labdanum, vetiver, white musk.
