DO YOU HAVE TO USE GLYCERINE IN THE FORMULA?
Yes, it is important to use Glycerine in Micromulse® LB formulations because it helps with stability and transparency. If glycerine is left out or replaced with either water or glycols, there is a risk instability will occur and the product will be cloudy.
HOW DO I LOWER THE VISCOSITY OF THE MICELLAR OIL I HAVE MADE AND STILL MAINTAIN CLARITY?
The choice of oil determines the amount of water that needs to be added to the formulation and in general, the more water in the product the lower the viscosity. If vegetable oils are being used and the viscosity is too high, replace a portion of the vegetable oil with an emollient of lower refractive index such as CCT or an ester.
MY PRODUCT LOOKS VERY CLOUDY, HOW CAN I FIX IT?
Firstly, ensure the cloudiness is not due to trapped air, by centrifuging or by smearing on a glass surface to check. Then see if the amount of water in the formula is correct by comparing framework formulations. If too much water has been added this is difficult to correct but if it is lower than recommended, then add small measured portions to the formulation until the product appears transparent.
CAN I MAKE A SOLID GEL PRODUCT WITH MICROMULSE® LB?
It may be possible, but it was designed with liquid products in mind.
CAN I CLASS MY MICELLAR OIL AS A MICROEMULSION?
No, we do not consider these systems to be microemulsions. This is because true stable microemulsions are a balance of surfactant, water and oil with a relatively high % of surfactant. The amount of surfactant in Micromulse® LB is lower than you would expect in a thermodynamically stable microemulsion.
CAN I USE ANY TYPE OF OIL IN MY FORMULATION?
There are a few types of oil that are not compatible with Micromulse® LB – please see our formulating guide from Alchemy Ingredients for more information.
CAN I HOMOGENISE THE OIL IN?
Yes, but this might be difficult for thicker formulations with no water. Instead, we recommend adding the oil using an overhead stirrer, then homogenising for a few minutes after all the oil is added. The homogenisation step is only needed for systems with high amounts of water (>2%), an overhead stirrer is sufficient for low/no water systems.
