⚗️ Chemical Overview

Phenol is both a manufactured chemical and a natural substance. It is a colorless-to-white solid when pure. The commercial product is a liquid. Phenol has a distinct odor that is sickeningly sweet and tarry. You can taste and smell phenol at levels lower than those that are associated with harmful effects. Phenol evaporates more slowly than water, and a moderate amount can form a solution with water. Phenol can catch fire. Phenol is used primarily in the production of phenolic resins and in the manufacture of nylon and other synthetic fibers. It is also used in slimicides (chemicals that kill bacteria and fungi in slimes), as a disinfectant and antiseptic, and in medicinal preparations such as mouthwash and sore throat lozenges. Phenol solution, [aqueous] is a white crystalline mass dissolved in an aqueous solution. Solution may be colorless to slightly pink in color with a distinctive phenol odor; sharp burning taste. Aqueous solution will be acidic and act as such. Toxic by ingestion, inhalation and skin absorption; strong irritant to tissues. Phenol, liquid appears as a colorless liquid when pure, otherwise pink or red. Combustible. Flash point 175 °F. Must be heated before ignition may occur easily. Vapors are heavier than air. Corrosive to skin but because of anesthetic qualities will numb rather than burn. Upon contact skin may turn white. May be lethal by skin absorption. Does not react with water. Stable in normal transportation. Reactive with various chemicals and may be corrosive to lead, aluminum and its alloys, certain plastics, and rubber. Freezing point about 105 °F. Density 8.9 lb / gal. Used to make plastics, adhesives and other chemicals.

📊 Comedogenicity

🛡️ Safety rating

Safety tier is a starting heuristic from regulatory status and comedogenic rating, not a dermatological verdict — see our Terms for the full disclaimer. Research confidence reflects how many real cited studies back this ingredient, not the strength of their findings.

🌍 Regulatory Status

💧 Skin Type Compatibility

Derived from this ingredient’s irritancy potential and comedogenicity rating against the needs of each skin type — e.g. oily and acne-prone skin are marked down for pore-clogging ingredients, sensitive skin for irritants. A starting heuristic, not a dermatological verdict.

📚 Research & Evidence

🔬 The Science

Camellia sinensis leaf extract is a green tea derivative that researchers have been investigating for skincare applications. Here’s what the current evidence shows:

#1: Antioxidant and anti-inflammatory effects (Int J Cosmet Sci, 2025): Laboratory experiments demonstrated that CSLE exhibits “potent antioxidant capacity” and reduces inflammation in skin cells. These are properties that help protect skin from oxidative damage. #2: Immune system interaction with skin bacteria (Int J Cosmet Sci, 2025): In lab settings, CSLE was shown to enhance the ability of dendritic cells (immune cells in the skin) to eliminate harmful microorganisms while preserving commensal microorganisms—the beneficial bacteria naturally present on skin.

This is notable because maintaining healthy skin flora is considered important for skin health. #3: Skin hydration and barrier function (Int J Cosmet Sci, 2025): When applied topically in clinical studies, CSLE improved skin hydration and barrier function (the skin’s ability to retain moisture and protect itself). Both acute (single application) and long-term use showed these benefits. #4: Mood and relaxation effects (Int J Cosmet Sci, 2025): Clinical studies found that topical CSLE application enhanced relaxation and improved mood states, including feelings of self-worth. Researchers measured this via alpha brainwave activity, though the mechanism isn’t fully explained in the abstract.

#5: Acne and redness reduction (Clin Cosmet Investig Dermatol, 2019): In a comparison study, a hydrogel containing CSLE (combined with aloe and mangosteen extract) reduced total acne lesions and skin redness more effectively than 1% clindamycin gel. Skin redness improvements were visible within 3 days. However, this study used a combination product, so CSLE’s individual contribution isn’t isolated. Important limitation: The research shows varied effects depending on manufacturing methods and formulation. One 2025 source notes that “a viable green tea extract exhibiting a diverse functional portfolio…is lacking,” meaning not all green tea extracts perform equally in skincare products.
