Cleansing Oil Formulation Questions

Regarding your questions about your cleansing oil formulation:

Thickening the Oil to Prevent Expansion

You asked if TaraGel can be used to increase viscosity and prevent the oil from expanding in heat. While "TaraGel" was not specifically found, Hemisqualane (C13-15 Alkane) Gel is an ingredient that can be used to increase the viscosity of oil-based formulas. It is designed to create a viscous oil appearance and is soluble in oil. Increasing the viscosity of your cleansing oil with a suitable gelling agent like Hemisqualane (C13-15 Alkane) Gel may help to improve its stability and reduce the issue of expansion and leakage when exposed to higher temperatures.

Masking Rancidity

You also asked about using an oil instead of fragrance to mask the rancidity odor. Using a non-fragrant oil is not an effective way to mask rancidity. Rancidity is a chemical process (oxidation) that causes oils to develop unpleasant odors. The most effective way to deal with rancidity is to prevent it by adding antioxidants to your formulation.

Consider adding an oil-soluble antioxidant to your cleansing oil blend. Some suitable options include:

• Hydroxyacetophenone (anti-oxidant)
• ActiveProtec™ OX
• Protec™ OX (Pentaerythrityl tetra-di-t-butyl hydroxyhydrocinnamate)
• Dimethylmethoxy Chromanol (1%, Oil Based)

These ingredients help to slow down the oxidation process, which is the root cause of rancidity, thus preserving the quality and odor of your oils.
