ActiveRelease™ Oleanolic is a water-based, cyclodextrin-enabled concentrate designed to deliver oleanolic acid (OA) in skin and scalp formulations where raw OA is difficult to disperse.

Oleanolic acid is a pentacyclic triterpenoid found widely in plants (including olive-derived sources) and has been studied for anti-inflammatory and antioxidant activity in skin-relevant models; a key practical limitation is very poor water solubility unless formulated in a delivery system.

Human evidence exists for well-formulated topical OA: in a double-blind split-face study, a polymeric-micelle OA ampoule applied around the eyes for 8 weeks improved wrinkle/roughness measurements versus control; additional cell and animal studies support barrier recovery/differentiation signaling and oxidative-stress modulation (evidence strength varies by endpoint).

Product Description: This SKU contains 11% oleanolic acid pre-complexed with cyclodextrin in purified water (high-active concentrate), giving a water-compatible format intended for leave-on products.

- Anti-aging texture support (human): improved peri-orbital wrinkle appearance in an 8-week split-face study when OA was delivered via micelles (human cosmetic study; delivery system dependent).

- Barrier support (preclinical): topical OA/related triterpenoids increased keratinocyte differentiation markers and supported barrier recovery with increases in epidermal lipids/ceramides via PPAR-α–linked pathways in model systems.

- Oxidative/inflammatory modulation (in vitro): OA reduced oxidative-stress readouts (e.g., ROS) and inflammatory signaling outputs (e.g., iNOS/NO) in keratinocyte models under exogenous stress.

- Sebum/acne claims: there is mechanistic rationale involving androgen/5α-reductase pathways, but robust clinical acne/sebum trials for OA alone are limited; position oily-skin benefits cautiously.

- Scalp/hair biology (preclinical): OA increased hair shaft elongation and proliferation markers in human hair follicle organ culture and promoted pro-growth signaling (e.g., β-catenin/Wnt) in a testosterone-induced alopecia mouse model; human data is mainly from multi-ingredient regimens that include OA.

Usage: Eye-area and face anti-aging products, barrier-support and calming products, and scalp serums/tonics for hair and scalp conditioning (leave-on preferred).

Mixing method:

- Add to the aqueous phase during cool-down (≤ 40°C) and mix until uniform.

- Recommended finished-formula pH: ~3.5–7.0; always confirm clarity and stability in your base.

- For emulsions: post-add during cool-down to the water phase or finished emulsion with moderate shear.

Usage rate: 0.5–5%

This concentrate delivers 11% oleanolic acid: use 0.5–5% to deliver ~0.06–0.55% OA. Typical: ~2% delivers ~0.22% OA.

Product characteristics: Clear to slightly opalescent aqueous solution.

Solubility: Water-compatible (cyclodextrin complex). Note that the solubilization capacity is finite—validate clarity at your intended use level, especially in very low-solvent or high-salt systems.

Storage: Store at 4–8 °C, protect from light, and keep tightly closed for long-term quality.
