Valuable CAS 90045-98-0 / ABRASIVE, HAIR CONDITIONING, SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

SIMMONDSIA CHINENSIS SEED EXTRACT, commonly known as Jojoba oil, is a unique liquid wax that closely resembles the skin's natural sebum. This characteristic enables it to balance skin oils, provide deep hydration, and deliver comprehensive protective benefits across a wide range of skin conditions.

Emollient Skin-identical ingredient Antioxidant Humectant Sebum regulator Anti-inflammatory Antibacterial Wound healing Barrier strengthening

Science

Mechanism of Action

This extract functions by mimicking the skin's physiological sebum, ensuring non-greasy application and minimal comedogenicity. Its rich composition of monounsaturated fatty acids acts as a humectant, drawing moisture into the stratum corneum, while its anti-inflammatory, antibacterial, and antioxidant properties, attributed to vitamin E and other vital compounds, support overall skin health. It actively reinforces the hydrolipidic film, effectively regulating sebum production and fortifying the epidermal barrier to prevent trans-epidermal water loss. Furthermore, Jojoba oil stimulates collagen synthesis, expediting wound healing processes, and neutralizes detrimental free radicals. Its distinctive wax ester structure forms a fine, semi-occlusive layer on the skin, simultaneously absorbing into the intercellular matrix via pores and hair follicles to enhance suppleness and softness.

Key findings

  1. 01 A jojoba oil-based regimen reduced sebum content by 25% and enhanced skin radiance by 24% within two weeks, outperforming caprylic/capric triglyceride.
  2. 02 Significantly reduces trans-epidermal water loss (TEWL) by up to 25%, contributing to increased skin suppleness.
  3. 03 Demonstrated efficacy in reducing pimple count in individuals with acne when incorporated into a clay mask used 2-3 times weekly over six weeks.
  4. 04 Accelerates wound closure through stimulation of collagen synthesis in fibroblast cells.
  5. 05 Proven to enhance the moisturizing properties of cream formulations with increasing concentrations.
