Oil Soap Formulation: Stability, UV Protection, and Thickening

Question

Based on an Oil Soap formula using Fractionated Coconut Oil and Jojoba Oil: Since the packaging is clear plastic and may be exposed to sunlight, is it necessary to add a UV protector like Protec™ UV? If so, what percentage should be used and at what step? If I want to increase the viscosity of the oil, I plan to add Oil Thick™ Clear at 5%. The instructions for Oil Thick™ Clear mention using high temperatures (90-100°C), but when warming Oil Soap, I usually use 70°C. Will using a higher temperature affect the quality of the oil?

Based on the staff's responses:

Regarding the shelf life of the Oil Soap formula:

The staff stated that the formula, using Fractionated Coconut Oil and Jojoba Oil as main components, is highly stable and has a shelf life of at least 2-3 years if not exposed to direct sunlight.
Vitamin E Acetate at 0.1% is sufficient for slowing down degradation; using more does not significantly increase effectiveness.
The formula does not contain components that degrade easily.

Regarding UV protection in clear packaging:

The staff believes adding a UV protector like Protec™ UV is unnecessary because Fractionated Coconut Oil, the primary oil, is very resistant to light and air and does not easily degrade, change color, or develop an off-odor.

Regarding adding Oil Thick™ Clear for viscosity:

Heating the mixture up to 100°C to incorporate Oil Thick™ Clear is acceptable for most ingredients in the formula as they are highly stable.
However, Vitamin E (referring to Vitamin E Acetate) and Jojoba Oil should be added after the mixture has formed a gel and cooled down to preserve their quality.
