## Questions & Answers

**Q: What percentage to you recommend to use this at? is it aldo suitable in preserving diy’s like flaxeed gel etc?**
A: Preservative Eco is used at up to 1% unless the product it is added to includes herbal decoctions in which case it is necessary to use 1.1% as herbal decoctions make a product more difficult to fully preserve.

It can be used to preserve homemade gels like Flaxseed gel but we suggest using the preservative at 1.1% just to be sure the gel is fully preserved.

**Q: Can i use this in a room spray please?**
A: Thank you for your enquiry. 

Yes it can. 

Kind Regards

The Aromantic Team

**Q: What is the shelf life of this product?**
A: The current batch has a best before date of 30/03/2022.  However, if used in your formulation before it has passed it's best before date, it will preserve your finished product for 12-18 months.
