Cloudiness Issue with Oil Thickener in Fractionated Coconut Oil for Dropper
คำถาม
I am formulating a product using 100% Fractionated Coconut Oil as the base oil. I tried mixing Oil Thick transparent at 0.2%.
- I heated the mixture to 70-80°C until the ingredient completely dissolved.
- While still hot, the mixture was clear as expected.
- However, after letting it cool down naturally to room temperature (without accelerated cooling), the color became translucent/cloudy, not clear.
The packaging is a transparent dropper bottle, so the product needs to be clear.
How can I resolve this issue to achieve a clear texture? Or, if there is another Oil thickener that results in a clear texture, could you please recommend it? I also need the texture to be slightly thicker because the current formulation tends to leak from the dropper, but it must still be thin enough to be drawn up by the dropper.
Thank you very much.

Regarding the issue you encountered where Oil Thick™ Transparent used at 0.2% in Fractionated Coconut Oil becomes cloudy upon cooling, despite needing clarity for dropper packaging:
Based on the information for Oil Thick™ Transparent (Dextrin Palmitate), it is stated that it can create a clear oil gel texture, and the recommended mixing method involves heating to 90°C until the powder is completely dissolved.
Potential Solutions for the Current Oil Thick™ Transparent:
- Increase Heating Temperature: Try increasing the heating temperature to 90°C as recommended for the product, and stir until you are absolutely sure the Oil Thick™ Transparent powder is completely dissolved before letting it cool. Incomplete dissolution might be one reason for the cloudiness upon cooling.
- Slightly Increase Concentration: If increasing the temperature doesn't help, you might try slightly increasing the concentration of Oil Thick™ Transparent, for example, to 0.3-0.5% (still within the recommended range of 0.1-10%) to see if it helps the gel maintain clarity better, while also observing if the viscosity remains suitable for using a dropper.
Alternative Clear Oil Gelling Agents:
If adjusting the use of Oil Thick™ Transparent does not yield the desired result, there are other oil gelling agents that are specified to provide a clear texture which you can consider as alternatives:
- Oil Thick™ Clear S: This is an oil gelling agent that provides a clear texture, suitable for almost all types of oils.
- Oil-Fix™ S: This is a gelling agent for Silicones and non-polar oils. Fractionated Coconut Oil falls into the non-polar category, so this should be compatible and provide clarity.
- Oil-Fix™ W: This is a gelling agent for all types of oils, both polar and non-polar.
You can experiment with these alternative gelling agents, starting with their recommended usage rates and testing their compatibility with Fractionated Coconut Oil, as well as the resulting clarity and viscosity to ensure it is suitable for use in a dropper.
