Is it safe to use more then the recommended usage for fragrance oils to make a perfume roll on? Most of the fragrance oils I purchased have a maximum ifra usage of 5%. Problem is I can't smell the end product mixed with the other 95% coconut oil. Is it dangerous adding more fragrance oil? I contacted someone that uses fragrance oils from the same company I bought and she uses 50% fragrance oil to the other 50% carrier oil. Is that dangerous? I have looked all over the web and I am very confused. Please help. Thank you!
