Green Tea Extract Powder (10:1) Canada

Green Tea Extract Powder (10:1) — Camellia sinensis

Professional cosmetic ingredient — not a finished product. Standardized 10:1 botanical extract in water-soluble powder form.

Green tea extract is one of the most extensively researched botanical actives in cosmetic science. At a 10:1 concentration ratio, 1g of this extract is equivalent to 10g of raw green tea leaf — meaning you achieve full efficacy at a fraction of the usage rate of a standard extract.

Understanding the 10:1 Extract Ratio & How to Calculate Usage

A 10:1 extract ratio means 10kg of raw Camellia sinensis leaf was used to produce 1kg of finished extract powder. The actives are concentrated tenfold.

Formula: 10:1 Extract Rate = Standard Rate ÷ 10

Example: A formula calling for 2% standard green tea extract requires only 0.2% of this 10:1 extract.

⚠️ Do not use at standard extract rates. Using 1–5% of this 10:1 extract equals 10–50% standard extract — far exceeding safe cosmetic use levels.

Key Specs

Key Benefits

• Antioxidant protection — EGCG neutralizes ROS, superoxide radicals, and singlet oxygen from UV and pollution
• Anti-inflammatory — inhibits NF-κB; reduces IL-1β, TNF-α, IL-6; calms redness and reactive skin
• Anti-acne & sebum regulation — inhibits 5α-reductase; reduces DHT-driven sebum and C. acnes proliferation
• Photoprotection — absorbs UV; enhances SPF efficacy alongside sunscreen actives
• Anti-aging — inhibits MMPs that degrade collagen and elastin
• Brightening support — mild tyrosinase inhibition; synergizes with dedicated brightening actives
• Hair & scalp — EGCG stimulates dermal papilla cells; inhibits DHT-mediated follicle miniaturization

Formulation Tips

1. Use at 0.1–0.5% only — 10:1 concentrate; see table above
2. Add at cool-down (<40°C) — catechins are heat-sensitive
3. Chelate: 0.1% Sodium Phytate prevents metal-ion-catalyzed oxidation
4. pH 4.5–5.5 — optimal catechin stability; higher pH causes darkening
5. Pair with Ferulic Acid (0.1–0.5%) for synergistic antioxidant protection
6. Preserve with Euxyl PE 9010 or equivalent

Pairings

• Ferulic Acid Powder — stabilizes catechins; adds UV absorption
• Niacinamide Vitamin B3 Powder — anti-acne + brightening + barrier repair
• Sodium Phytate — essential chelator; always include at 0.1%
• Azelaic Acid Powder — anti-acne + anti-rosacea combination
• 3-O-Ethyl Ascorbic Acid — antioxidant + brightening serum

Example: 0.2% Green Tea Extract (10:1) + 0.5% Ferulic Acid + 3% Niacinamide + 0.1% Sodium Phytate, pH 5.0–5.5, 0.8% Euxyl PE 9010. Equivalent to a 2% standard green tea formula.

Storage & Safety

Store sealed at 10–25°C away from light and moisture. Hygroscopic — will clump if exposed to humidity. Shelf life: 24 months. For external use in finished cosmetic formulations only. Consult SDS before use.
