TL;DR. This ingredient is primarily an emollient botanical oil, used to soften skin, reduce transepidermal water loss, and add cushion to balms, oils, creams, and salves.
What does Tamanu do in a cosmetic formula?
This ingredient is primarily an emollient botanical oil, used to soften skin, reduce transepidermal water loss, and add cushion to balms, oils, creams, and salves.
Is Tamanu clean?
From a clean-beauty perspective, it is generally well accepted because it is a minimally processed plant oil with no common restricted-list issue. Like many seed oils, it can be a concern for very reactive skin if oxidized, so freshness and antioxidant support matter.
Is Tamanu sustainable?
This material is plant-derived and readily biodegradable, with a lighter end-of-life profile than persistent synthetic film-formers. Sustainability depends on responsible seed sourcing, local harvesting practices, and whether mechanical pressing is used instead of solvent-heavy extraction.
Is Tamanu COSMOS-approved?
It is generally compatible with COSMOS-natural and COSMOS-organic when sourced from an approved botanical supply chain and processed by permitted physical methods. It fits Green Chemistry principles well when cold-pressed or mechanically extracted, since it uses renewable feedstock, simple processing, and biodegradable chemistry.
How does Tamanu work chemically?
This compound is a triglyceride-rich lipid mixture with high levels of oleic and linoleic fatty acids plus resinous minor constituents that influence color, odor, and skin feel. It is often used around 1 to 10% in emulsions or higher in anhydrous products, and its unsaturated profile benefits from antioxidants, low heat processing, and opaque or air-limited packaging.
