Science
Mechanism of Action
Acting primarily through its major constituents, thymol and carvacrol, Thymus Zygis Oil disrupts microbial cell membranes, leading to structural damage and disintegration of various bacteria and fungi. Its antioxidant action involves inhibiting lipid peroxidation and neutralizing free radicals. Furthermore, it demonstrates anti-inflammatory effects and inhibits biofilm formation, contributing to comprehensive skin defense.

Dusting Analysis
As an essential oil, Thymus Zygis Oil is not typically associated with dusting concerns relevant to powdered ingredients.
The Formula
Formulation
Stability
The stability of key active components, such as thymol, can decrease over time. Optimal preservation of thymol, γ-terpinene, and carvacrol is achieved by freezing and storage at -20 °C.
Conflicts
- High, undiluted concentrations can cause skin irritation.
- It is not water-soluble; direct contact of undiluted oil with water may cause skin irritation.
- Contraindicated for individuals with allergies to thyme or other plants from the Lamiaceae family due to potential cross-reactivity.
Safety
Safety Profile
Thyme Oil (Thymus zygis) is Generally Recognized As Safe (GRAS) by the FDA (21CFR182.20) for use as a flavoring agent. It is considered suitable for cosmetic application under EU Regulation (EC) No 1223/2009, with natural Methyl Eugenol content limited to 0.03%. Hypersensitivity reactions have been reported. Due to its potent nature, topical application requires dilution, typically up to a maximum of 10% in cream or 20% in vegetable oil. It is not recommended during pregnancy, breastfeeding, or for children under 6 years of age.
