How to ... formulate natural, yet sensorial anhydrous balms with Compritol® 888 CG? Is there a specific process of formulation?

There are two important steps:

STEP 1:

it is essential to ensure that the Compritol® 888 CG is perfectly melted in the oil phase.
For this, ensure that the mixture is heated to 80-85°C during at least 5-10 minutes.
Oils that are sensitive to heat can be added later below 75°C.
Use a stirrer or mixer to ensure good dispersion.
Once fully melted, the Compritol® pellets or powder should no longer be visible in the melted oil phase; the oil phase should be transparent or translucent.

STEP 2:

Begin cooling. During this step, it is necessary to maintain a high shear (rotor stator) from the time when the formula becomes hazy (start of crystallization) or starts to thicken.
Mix using rotor-stator at 2500 rpm until cooling is complete.

How to... avoid agglomerates and crystals in anhydrous balms with Compritol® 888 CG, depending on the batch size?

A blend of Compritol® 888 CG / Geleol Hydrogenated Castor Oil in a ratio of a 2/2/1 is recommended between 1à and 15% depending on the consistency desired and the oil types. This should ensure homogeneous recrystallization of the Compritol® 888 CG.

The small particles may also result from insufficient melting of Compritol®  888 CG. Make sure that it is fully melted before cooling.
