❓ Frequently Asked Questions

❓ Is Polysorbate 20 natural?

It's derived from sorbitol (sugar alcohol) and fatty acids, but the ethoxylation process makes it semi-synthetic.

❓ Why is my product cloudy?

Likely insufficient Polysorbate 20 or inadequate mixing. Increase concentration or mix more vigorously.

❓ Can I replace it with something natural?

For solubilizing, options are limited. Caprylic/Capric Triglyceride can help but isn't a direct replacement.
