Acacia Catechu Wood Extract

Acacia catechu wood extract is derived from the heartwood of the acacia catechu tree, a species native to Asia. The extract contains tannins and polyphenolic compounds, which are naturally occurring plant molecules known for their antioxidant properties. In skincare formulations, it functions primarily as an antioxidant ingredient.

The tannins present in this extract are the same compounds responsible for the astringent and colour-stabilising effects observed in wine production, where acacia wood has been studied as an alternative to oak. When incorporated into skincare products, these tannins may help protect skin from environmental stressors.

Acacia catechu wood extract works through its polyphenolic and tannin compounds, which act as antioxidants. These molecules are electron donors that can stabilise and neutralise free radicals—unstable molecules that form when skin is exposed to environmental stressors like UV radiation and pollution. By preventing free radical damage, the extract may help protect skin cells from oxidative stress.

The tannin content may also contribute mild astringent activity, which refers to a tightening or toning sensation on the skin surface. This property is thought to derive from the tannins' ability to interact with proteins in the skin.

Acacia catechu wood extract is typically used as part of a broader formulation rather than as a single-ingredient product. It is most effective when combined with other proven antioxidants and sun protection, as no single ingredient can fully replace the importance of daily sunscreen in defending against environmental stressors. Use as directed by the product instructions.
