I'm interested in your Lavender Essential Oil and its compatibility with melted paraffin wax used in treatments for hands and feet. Can you confirm whether it can be safely added to paraffin wax during the heating process? Additionally, are there any specific handling instructions I should be aware of when using it with a wax machine? Your insights on this would be greatly appreciated, as I'm looking to enhance the treatment experience. Thank you!
