Mixing MSH White Absorb™ and Licorice Extract in Formulations

Subject: Regarding mixing MSH White Absorb™

Based on the conversation, here is a summary of the key points regarding mixing MSH White Absorb™ and Licorice Extract:

• MSH White Absorb™ and Grape Seed Oil:

  • Your calculation for a 4% mixture by weight (4g MSH White Absorb™ + 96g Grape Seed Oil for 100g total) is correct.
  • Measuring by volume (ml) is generally not equivalent to measuring by weight (g) because different substances have different densities. Oils are typically less dense than water, meaning 1ml of oil weighs less than 1g.
  • While weighing is the most accurate method, if you must use volume measurement, using a concentration slightly below the maximum recommended (like 4% when the maximum is 6%) can help mitigate potential errors, especially for ingredients like MSH White Absorb™ in oil where slight inaccuracies are less critical.
  • For ingredients where precise concentration is crucial for safety or efficacy (e.g., preservatives), weighing is strongly recommended.

• Licorice Extract (Licochalcone A):

  • The recommended usage percentage (0.1-1%) refers to the product itself, not the pure extract substance within the product.
  • Therefore, to achieve a 1% concentration in your final formulation, you should mix 1g of the Licorice Extract product with 99g of your base (e.g., water or cream base).

We hope this clarifies the mixing process.
