Tea Tree Brown Liquid Extract — Melaleuca alternifolia — Cosmetic Grade
Tea Tree (Melaleuca alternifolia) is one of the most clinically validated antimicrobial botanicals in modern cosmetic science. Its primary bioactive compounds — terpinen-4-ol, γ-terpinene, and α-terpineol — have been extensively studied for their broad-spectrum antimicrobial, anti-inflammatory, and wound-healing properties, making Tea Tree a cornerstone active in acne, scalp, and sensitive skin formulations.
This brown liquid extract delivers the key bioactive compounds of Melaleuca alternifolia in a ready-to-use, water-soluble form for direct incorporation into the water phase of serums, toners, cleansers, acne treatments, and scalp formulations.
Professional cosmetic ingredient — not a finished product.
Key Benefits
-
Broad-spectrum antimicrobial — terpinen-4-ol is clinically validated against C. acnes and other skin-relevant microorganisms; a gold-standard active for acne-prone skin formulations
-
Anti-inflammatory & soothing — inhibits pro-inflammatory cytokines and reduces redness, swelling, and irritation associated with acne and reactive skin
-
Acne & blemish support — reduces acne lesion count and severity; comparable to benzoyl peroxide in some clinical studies with a superior tolerability profile
-
Scalp & dandruff support — antimicrobial and anti-inflammatory activity targets Malassezia and scalp irritation; clinically studied for dandruff reduction
-
Wound healing support — supports skin repair and reduces the risk of secondary infection in compromised skin
-
Antioxidant activity — flavonoids and polyphenols contribute to free radical neutralization and oxidative stress reduction
How to Use
-
Incorporation: Add directly to the water phase or at cool-down (below 40°C) to preserve heat-sensitive terpinen-4-ol and flavonoids
-
Recommended Usage Rate: 1–10% in finished formulations (2–5% most common for serums and toners)
-
Solubility: Water-soluble; incorporate in the water phase
-
Processing temperature: Add at cool-down (below 40°C) preferred; avoid prolonged high heat
-
pH & shelf life: Refer to your supplier's Certificate of Analysis (CoA) or Technical Data Sheet (TDS) for confirmed values
