proportion

Type 1 : Perfume 30 % + 70% base type 1

Type 2 perfume 35 % + 65 % base type 1

Is a good smell, but the radius of diffusion is not very wide. We try to add more perfume, but the smell is quite dense. We want a light, airy scent.

1. Can alcohol help? Is it necessary to add alcohol to mix in order to spread the smell well?

(We tried adding alcohol to the perfume and base, and the layers separated and the perfume ran out very quickly.)

2. But the formula doesn't require alcohol, is there any other formula that can help? for wide distribution of scents

thank you
