Astrocaryum Tucuma Seed Butter

Astrocaryum tucuma seed butter is extracted from the seeds of the tucuma palm, native to South America. It is a solid-to-semi-solid fat rich in fatty acids, particularly oleic and linoleic acid, which are structural components of healthy skin.In skincare formulations, it functions primarily as an emollient and skin conditioner. It softens and smooths the skin surface, helping to reduce moisture loss and create a protective barrier on the skin.

The butter's fatty acids penetrate or sit on the skin surface, reducing transepidermal water loss (TEWL) and creating a conditioning film. The oleic and linoleic acid content helps reinforce the skin's natural lipid matrix, which is important for barrier function and overall skin resilience.

Tucuma seed butter works well in moisturisers, balms, and body products. In formulations, it is typically used at lower concentrations (under 5%) to avoid an overly occlusive feel. It can be combined with lighter emollients to modulate texture and absorption on different skin types.

Generally well-tolerated by most skin types. Those prone to fungal acne may wish to exercise caution, as plant butters can occasionally feed malassezia; patch testing is advisable if you have a history of fungal sensitivity.
