Why do we use it in formulations? In watery concoctions like room sprays, body sprays, and hand washes Olivem 300 will self-disperse so you can easily include a bit of oil, making surfactant products gentler and mists more moisturizing. It can also help solubilize essential oils and fragrance oils.

In oil-based products like cleansing oils and cleansing balms Olivem 300 adds cleansing power and boosts rinse-off. I’ll often include it in body oils or after-bath oils because it means the body oil will self-emulsify with any water on the skin during application, but unlike a polysorbate it isn’t sticky and still has a lovely skin feel.

Do you need it? It isn’t essential, but I enjoy having it around and using it.
Strengths It’s an easy way to incorporate a bit of oil into otherwise watery concoctions.
Weaknesses It can be hard to find in some parts of the world.
Alternatives & Substitutions Check out this page to learn more about making solubilizer substitutions. Water soluble shea butter (PEG-50 Shea Butter) would be a fairly simple alternative.
