Science
Mechanism of Action
This ingredient functions primarily by creating a biomimetic, water-resistant film on the skin's surface, which actively minimizes transepidermal water loss (TEWL) and seals in moisture. Its close structural resemblance to human sebum facilitates seamless integration, thereby reinforcing the skin's intrinsic barrier function. Beyond its emollient properties that impart skin softness, it stimulates the endogenous synthesis of pro-collagen III and hyaluronic acid, contributing to enhanced skin structure and repair. Furthermore, it exhibits anti-inflammatory and antioxidant activities, providing a soothing effect and protection against environmental stressors, while also acting as a valuable fragrance retainer in formulations.

Key findings
- 01 A pilot study demonstrated that a topical formulation containing 1.25% Hydrolyzed Jojoba Esters, when combined with 3.75% glycerol, significantly reduced transepidermal water loss (TEWL) and enhanced skin hydration for 8 to 24 hours post-application.
- 02 Clinical evaluations confirmed that Hydrolyzed Jojoba Esters, when incorporated into various cosmetic products such as makeup and lotions, consistently improved skin hydration for a minimum duration of 8 hours after application.

Stability
Hydrolyzed Jojoba Esters are recognized for their robust stability, generally not requiring specialized storage conditions. They demonstrate solubility in water within specific pH ranges, typically above 10, as well as in most alcohols and glycols. This ingredient can notably enhance the oxidative stability of sensitive antioxidants in formulations. Its inherent high pH also makes it suitable for use as a gel neutralizer, particularly in carbomer-based thickening systems.
Synergies
- Glycerol (enhances hydration and TEWL reduction)
- Antioxidants (improves oxidative stability)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed that Jojoba Oil and its derivatives, including Hydrolyzed Jojoba Esters, are safe for use in cosmetic applications. The CIR panel specifically noted that components of jojoba oil are not anticipated to penetrate the skin due to their considerable molecular weight. Further assessments on related jojoba ingredients, such as undiluted Jojoba Seed Oil and Jojoba Alcohol, have shown them to be non-irritating, non-sensitizing, and non-mutagenic. Its usage is also permitted under the general provisions of the Cosmetics Regulation in the European Union.
