This is the busiest jar of the four to look at. Three different petals go into it, lavender, rose and calendula, so the salt is shot through with purple, deep red and marigold yellow instead of reading white. The base is the same four salt blend SopranoLabs uses across the line: Dead Sea salt, Mediterranean sea salt, Epsom salt and sea salt.

The scent is sweet orange with ylang-ylang behind it, which lands somewhere between citrus and heavy floral and is the least predictable of the four. About a quarter of the jar makes a bath, roughly four soaks per jar. If you would rather keep the petals out of the drain, tip the salt into a muslin bag first.

SopranoLabs was founded in New York in 2015 by the opera singer Inna Los, who still formulates every product herself. The maker states that everything is handmade from scratch in small batches, vegan and never tested on animals, and made without parabens, SLS, phthalates, fillers, artificial dyes, synthetic preservatives, GMOs, gluten, dimethicone or mineral oil.

Clear glass jar with a screw cap, 8 oz / 227 g. The label reads RENEW, Orange Ylang-Ylang Bath Salt.
