Question
I would like to inquire about the differences between Hectorite Gel™ (Cyclomethicone Base) (product_id 665) and Hectorite Gel™ (Isononyl Isononanoate Base) (product_id 10745).
- What are the key differences between these two products?
- If I want to formulate a thick foundation, which one would you recommend?
Answer
The main difference between the two Hectorite Gel™ products lies in the carrier base and the concentration of the gelling agent, which affects their compatibility with your formula:
1. Hectorite Gel™ (Cyclomethicone Base)
- Base: Cyclomethicone (Silicone).
- Active Concentration: Contains 20% Disteardimonium Hectorite.
- Best For: Formulations where the main oil phase is Silicone (such as Cyclomethicone or Dimethicone).
- Key Features: It is a "High Viscosity" type, providing excellent thickening and pigment suspension in silicone-based makeup. It gives a light, silky, and non-greasy feel.
2. Hectorite Gel™ (Isononyl Isononanoate Base)
- Base: Isononyl Isononanoate (Ester).
- Active Concentration: Contains 10% Disteardimonium Hectorite.
- Best For: Formulations where the main oil phase consists of Oils or Esters.
- Key Features: Suitable for oil-based makeup or skincare. It helps suspend pigments and pearls in oil systems.
Recommendation for a Thick Foundation:
If you want to create a thick foundation, the choice depends on your formula's base:
- For a Silicone-based Foundation (Most Common): We recommend Hectorite Gel™ (Cyclomethicone Base). Since it has a higher active concentration (20%) and is a high-viscosity grade, it is more effective at thickening silicone systems and keeping pigments perfectly suspended without settling.
- For an Oil-based Foundation: Use Hectorite Gel™ (Isononyl Isononanoate Base) if your formula relies heavily on esters and natural oils rather than silicones.
Usage Tip: Both products are thixotropic, meaning the foundation will become easier to spread when applied (shear force) but will stay thick and stable in the bottle. The typical usage rate is 2.5-10%.
