- Squalane
- Emollient from plants or synthetic; light texture
- Simmondsia Chinensis Seed Oil
- Common in dry/damaged hair; superior penetration vs mineral oils, low comedogenic risk, poor oxidative stability.
- Prunus Armeniaca Kernel Oil
- Plant oil for emollience and nutrition; contains proteins that may cause sensitivity, use caution in sensitive skin
- Prunus Amygdalus Dulcis Oil
- Sweet almond oil, light emollient; suitable for sensitive skin, caution for nut allergies.
