Can I use a penetration enhancer in a formulation that contains a UV protectant formulation?

hello

If I use Phenylethyl Resorcinol , which should include a UV protectant such as ActiveProtec™ UV or BEMT ( Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) but with a penetration enhancer such as DMI, will those sunscreens penetrate the skin more easily? Is it dangerous?

or if put in an opaque bottle No UV protection is required.

thank you

Is Pure-Phytosterols™ classified as Natural Origin?

hello

Pure-Phytosterols ™ is classified as Natural Origin? I see in HALAL sent to Origin it says Synthesis but in the description says it is extracted from plants (Soy).

thank you

Hydroxypinacolone Retinoate crystallized when added to formulations.

hello

Tried Perfect-A in both liquid and powder form (dissolved in DMI until clear).
But when put in emulsion in the last step crystallization. It's a yellow streak.
Perfect-A 10™ liquid is also used, so I dropped Perfect-A 10™ in water and it crystallized into a yellow streaky powder as well.

I don't know how to fix it.

thank you
