Melaleuca Alternifolia (Tea Tree) Leaf Extract (10,000Ppm)
Melaleuca Alternifolia (Tea Tree) Leaf Extract is derived from the leaves of the tea tree, native to Australia, where it has been used for nearly 100 years for its antiseptic and anti-inflammatory properties. It is a complex chemical mixture of approximately 100 components, with the major ones being terpinen-4-ol (~40%), γ-Terpinene (~23%), and α-Terpinene (~10%). Terpinen-4-ol is considered the primary active component, though most constituents contribute to the oil's overall antibacterial, antiviral, and antifungal effects. Note: the source page describes the oil form (Melaleuca Alternifolia Leaf Oil); this profile is for the extract form at 10,000 ppm concentration.
Tea tree extract is a well-established anti-acne ingredient, with multiple studies confirming efficacy against P. acnes; a 5% TTO gel has been shown comparable in effectiveness to 5% Benzoyl Peroxide lotion, though with slower onset and fewer side effects. It also exhibits broad-spectrum antimicrobial (antibacterial, antiviral, antifungal) and anti-inflammatory actions supported by clinical and microbiological research.
Should never be applied undiluted to skin. Irritant and allergic reactions can occur, particularly from oxidation products that form in older or improperly stored oil. Sensitive skin types should use with caution. Proper storage (cool, dry, dark place) is important to minimize oxidation and allergen formation.
