Theobroma Grandiflorum Seed Butter

This ingredient is also known as cupuacu butter. It's a soft, creamy plant fat that works as a skin-conditioning agent and often marketed as the plant-based alternative to lanolin.

The composition of this butter is dominated by oleic acid, stearic acid, and smaller amounts of palmitic, linoleic, and arachidic acids. There's also a useful dose of phystosterols.

That fatty-acid-and-sterol combo is why this ingredient behaves like a richer cousin of shea butter: the lipids reinforce the skin's surface and slow water loss while the sterols help support the barrier.

There's some early research too: a mouse study found cupuacu butter emulgels had antioxidant activity and a measurable photoprotective effect against UVB damage.

Overall, this is a well-tolerated ingredient but those prone to congestion might prefer formulations with lower concentrations.

Fungal acne: Cupuacu butter's fatty acids are mostly "locked up" in triglycerides that Malassezia can't easily feed on, but the yeast can slowly break these down to access the free fatty acids. Therefore, ingredient may not be fungal acne safe.
