Camellia Sinensis Leaf Distillate — INCI reference

What it is

Camellia Sinensis Leaf Distillate is the water-based byproduct of steam distillation of green tea (Camellia sinensis) leaves. Unlike concentrated leaf extracts, this distillate captures volatile and water-soluble phytochemicals including polyphenols, catechins (notably EGCG), tannins, flavonoids, amino acids, and mineral salts. It is commonly incorporated into toners, facial mists, essences, and lightweight serums where it provides antioxidant protection against free radicals, gentle astringency to help minimize pore appearance, and soothing effects suitable for sensitive or acne-prone skin. The ingredient also offers mild humectant properties, supporting skin hydration. Its typical pH of 3.8–4.0 makes it compatible with skin's natural acid mantle. Usage levels in formulations typically range from 30–80%.

Safety & warnings

Generally considered well-tolerated. The CIR Expert Panel concluded Camellia sinensis-derived ingredients are safe in cosmetic use when formulated to be non-sensitizing. Individuals with known sensitivity or allergy to Camellia sinensis or related Theaceae plants should patch-test before use. The tannin and catechin content may cause mild astringency. No significant comedogenic, phototoxic, or endocrine-disrupting concerns have been identified for this ingredient class in cosmetic use.

Origin & sourcing

Derived from the leaves of Camellia sinensis, an evergreen shrub native to the borderlands of southwestern China, northeastern India, and Myanmar. The distillate is produced by passing steam through dried or fresh green tea leaves; the condensed vapor forms an aqueous liquid carrying water-soluble and volatile leaf constituents. Organic-certified versions sourced from Europe (including France) are available and carry ECOCERT certification. The CAS number 84650-60-2 applies to the green tea-derived component, with water (CAS 7732-18-5) as the carrier phase.

History

Camellia sinensis has been cultivated for tea production for at least 3,000 years, with documented Japanese tea culture dating to the 9th century. Green tea's cosmetic applications gained momentum in the late 20th century as research confirmed the antioxidant activity of catechins, particularly EGCG. The Cosmetic Ingredient Review (CIR) Expert Panel completed a comprehensive safety assessment of Camellia sinensis-derived cosmetic ingredients, concluding they are safe at present concentrations when formulated to be non-sensitizing (final report 2014/2019). The distillate form entered cosmetic formulations as formulators sought lighter, water-phase delivery of green tea's benefits.

Questions everyone asks

How does Camellia Sinensis Leaf Distillate differ from green tea leaf extract?

The distillate is produced by steam distillation and captures primarily volatile, water-soluble compounds. Green tea leaf extract is typically a concentrated preparation (often in glycol or alcohol solvents) containing higher levels of polyphenols and catechins.

What skin types benefit most from this ingredient?

It is particularly suited to oily, combination, acne-prone, and sensitive skin types. Its astringent properties help reduce excess sebum and pore appearance, while its anti-inflammatory catechins soothe redness and irritation. It is generally considered compatible with most skin types.

Does the distillate retain the antioxidant activity of green tea?

Yes, though typically at lower potency than concentrated extracts. Steam distillation captures water-soluble polyphenols, catechins, and flavonoids that provide measurable antioxidant activity.

Is this ingredient the same as Camellia Sinensis Leaf Water on labels?

These terms are used interchangeably in the industry. Both refer to the aqueous condensate obtained from steam distillation of green tea leaves. INCI terminology may list it as either 'Camellia Sinensis Leaf Water' or 'Camellia Sinensis Leaf Distillate' depending on the supplier's naming convention.
