Science
Mechanism of Action
This ingredient leverages biomimicry due to its molecular structure closely resembling the wax esters naturally found in human sebum, which constitutes approximately 30% of skin's oils. This similarity enables deeper skin penetration and recognition as a natural component. It operates as an emollient, delivering profound hydration and skin softening while effectively locking in moisture and significantly reducing transepidermal water loss (TEWL). Furthermore, it contributes to increased skin elasticity and provides protection against moisture depletion. The presence of Provitamin A and Vitamin E imparts an antioxidative effect, and its fatty acid composition fosters a smooth, cared-for skin sensation. It exhibits moisture-binding capabilities and actively helps normalize the skin's natural oil production by signaling adequate sebum levels, thereby mitigating overproduction, greasiness, and pore congestion. The ingredient also possesses anti-inflammatory, antimicrobial, and antifungal properties, enhancing skin barrier function, elasticity, and suppleness for a firmer, more toned appearance, while improving product texture and spreadability.

Key findings
- 01 Demonstrated improved transepidermal water loss (TEWL) within 30 minutes following SLS-induced irritation and barrier disruption, with effects sustained for at least 2 hours. It also effectively reduced erythema.
- 02 Evaluated for its impact on skin sensory properties in 10 volunteers, resulting in positive subjective responses.

Stability
Jojoba Oil/Wax Polyglyceryl-3 Esters exhibit solubility in oils and limited water solubility, making them suitable for both oil-in-water (O/W) and water-in-oil (W/O) emulsions, where they enhance stability and contribute to a rich, non-greasy texture. The foundational jojoba wax is known for its heat stability and high resistance to oxidation, which can extend cosmetic product shelf life and prevent rancidity. It effectively functions as an emulsifier and stabilizer, promoting thorough blending and stability of disparate ingredients. While a precise optimal pH range for this specific INCI was not identified, Jojoba Esters generally maintain stability at a neutral pH.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed the safety of polyglyceryl fatty acid esters, a broad category encompassing Polyglyceryl-3 Esters, concluding they are safe for cosmetic use under current practices and concentrations when formulated to be non-irritating. A CIR report specifically on Jojoba Esters indicated they are non-irritating during induction and non-sensitizing during challenge in repeat insult patch tests. Jojoba Esters are generally classified as non-comedogenic to slightly comedogenic.
