A beaker with clear liquid on a digital scale. We added SIMULGEL™️ EG emulsifier to the beaker. It hasn't been mixed yet.

I just went into this in the shopping list post for the new introduction to cold process emulsifiers series running from October 2025 to March 2026 here every Formulating Friday starting October 3, 2025, that’ll be available to Foundation, Formulation, and Innovation subscribers to the site here, but I thought it so important, it should...
