Valuable CAS 92201-55-3 / 8000-27-9 / FRAGRANCE, PERFUMING, SKIN CONDITIONING

Cedrus Atlantica Bark Oil is a multi-functional essential oil revered for its potent anti-inflammatory, antimicrobial, and skin-conditioning properties, effectively supporting diverse skin health concerns from acne to compromised barrier function.

Summary

Antimicrobial/Antibacterial Anti-inflammatory Perfuming

Science

Mechanism of Action

This bark oil operates through several pathways to enhance dermal health. It exhibits robust antiseptic and antimicrobial actions, actively reducing bacterial proliferation and inflammation, rendering it particularly beneficial for acne-prone complexions. Its anti-inflammatory prowess stems from inhibiting enzymes like 5-lipoxygenase and the primary constituent, cedrol, which reduces nitric oxide production in macrophages. Beyond calming irritation, it influences sebum production by regulating sebaceous gland activity and possesses lipolytic effects that aid in breaking down fatty substances. The oil also contributes to improved skin elasticity and softness through moisturizing and nourishing effects, while simultaneously reinforcing the skin barrier by minimizing transepidermal water loss (TEWL). Furthermore, astringent qualities help refine pores, and components like cedrol and atlantone may stimulate local blood flow and fibroblast activity, promoting regeneration and potentially softening scars. Antioxidant properties additionally protect the skin from oxidative stress.

Research

Clinical Evidence

Medium confidence
Effective range 0.5%–2%%
Optimal

Optimal topical percentages are not explicitly defined across all benefits; however, in vitro studies show antifungal activity between 0.5-1% and antibacterial activity between 1-2%.

Key findings

  1. 01 A rat study demonstrated significant, dose-dependent anti-inflammatory effects, with 50 mg/kg reducing carrageenan-induced edema by 98.36%, comparable to pharmaceutical controls.
  2. 02 In vitro studies report antifungal activity against various species (e.g., Aspergillus niger) with minimum inhibitory concentrations (MICs) between 0.5-1%.
  3. 03 In vitro studies show antibacterial activity against tested bacteria with MICs ranging from 1-2%.
  4. 04 Cedrol, a primary constituent, inhibited nitric oxide production in macrophages, indicating strong anti-inflammatory activity.
  5. 05 Cedarwood extracts exhibited significant antimicrobial effects against Staphylococcus aureus and Candida albicans.
  6. 06 Clinical trials using aromatherapy blends indicated measurable reductions in transepidermal water loss (TEWL), suggesting improved skin barrier function.

Safe with restrictions
Pregnancy
Caution
Sensitization risk Moderate

This ingredient is approved but restricted by the SCCS of the EU Commission. It is generally safe for cosmetic use but must always be diluted with a carrier oil before topical application; high concentrations may induce skin sensitivity, irritation, or allergic reactions. Patch testing is recommended prior to use. It is not recommended for use by pregnant or breastfeeding women, or children. Repeated or prolonged contact can lead to redness, irritation, and scaling (dermatitis). IFRA standards recommend that essential oils from the Pinaceae family, including Cedrus atlantica, maintain peroxide levels below 10 millimoles peroxide per liter. A significant sustainability concern exists as Cedrus Atlantica Wood Oil is listed as an endangered species by the IUCN Red List due to overharvesting.
