Compatibility of PE-1 Aqua with Silicone and Fragrance

Regarding your question about using PE-1 Aqua in a water-soluble formula containing silicone and fragrance:

• Silicone: PE-1 Aqua has no effect on silicone.
• Fragrance: This is a significant consideration. While most fragrance components are oil-soluble, PE-1 Aqua can unpredictably affect the absorption of oil-soluble substances, potentially increasing the absorption of harmful components present in some fragrances. It is recommended to check the fragrance's IFRA Conformity document to identify any potentially irritating or dangerous substances that should not be absorbed into the skin. If such substances are present, it might be best to avoid using that fragrance or using it with PE-1 Aqua.
