Science
Mechanism of Action
This extract is rich in potent bioactive compounds, including terpinen-4-ol precursors, polyphenols, and flavonoids. These components impart significant antiseptic, antimicrobial, and anti-inflammatory benefits, which enable the extract to combat acne-causing bacteria, reduce inflammation, and calm irritated skin. It also aids in regulating sebum production and maintaining a healthy skin microflora while reducing excess oil.

Dusting Analysis
With an effective and safe concentration range of 0.1% to 5%, this extract is typically incorporated at functional levels within cosmetic formulations, rather than being present in negligible, 'dusted' amounts.
The Formula
Formulation
Stability
Optimal stability is observed within a pH range of 4.0 to 7.0. To mitigate potential sensitization risks, formulators must employ methods to minimize the oxidation of the oil components naturally present within the extract during product development and storage.
Safety
Safety Profile
The CIR Expert Panel deems Melaleuca Alternifolia (Tea Tree)-Derived Ingredients, including this extract, safe for cosmetic use under conditions where formulations are non-sensitizing. A critical restriction involves minimizing the oxidation of tea tree oil components within the final product, as oxidized forms can act as sensitizers. While specific maximum concentrations for this extract are not individually defined by CIR, related Tea Tree Leaf Oil has reported maximum leave-on concentrations (e.g., 0.63% in cuticle softeners, 0.5% in aerosol deodorants). Minimal concerns for irritation or sensitization are noted within the 0.1-5% range, though rare allergic reactions can occur, particularly with high concentrations or in individuals sensitive to tea tree. Patch testing is recommended for sensitive individuals.
