I use this preservative im a number of formulas. The quality is very good. Haven’t had any spoilage. I would like to see the expiry date on the bottle or at least on the website though.

Description
Bearberry Clear Liquid Extract — Natural Brightening Active for Cosmetic Formulations
Bearberry (Arctostaphylos uva-ursi) extract is one of nature's most studied brightening actives, prized for its naturally high arbutin content — a tyrosinase inhibitor that interrupts melanin synthesis at the source. The result: a clearer, more even complexion without the harshness of synthetic alternatives. This clear liquid form offers easy incorporation into a wide range of water-based formulations, from lightweight serums to rich moisturizers.
Whether you're formulating your first brightening serum or building a clinical-grade hyperpigmentation protocol, Bearberry Clear Liquid Extract delivers consistent, skin-compatible performance.
Key Benefits
- Brightens & evens skin tone — naturally derived arbutin inhibits tyrosinase activity, reducing the appearance of dark spots, post-inflammatory hyperpigmentation (PIH), and uneven tone
- Antioxidant protection — rich in hydroquinone glycosides and polyphenols that neutralize free radicals and support skin resilience
- Gentle & skin-compatible — well-tolerated across skin types, including sensitive skin; suitable for daily-use formulations
- Clear liquid format — easy to incorporate without affecting the colour or clarity of finished formulations
- Versatile application — effective in serums, toners, moisturizers, eye creams, and targeted spot treatments
How to Use
- Incorporation: Add to the water phase or cool-down phase (below 40°C / 104°F) to preserve bioactive integrity
- Recommended Usage Rate: 1–5% in finished formulations
- pH Compatibility: Performs best at pH 4.5–6.5; avoid highly alkaline systems
- Solubility: Water-soluble; miscible in hydro-alcoholic systems
