3.1. Chemical compatibility and material science

Essential oils are complex mixtures of volatile organic compounds, including monoterpanoids, seesquiterpeneoids, and phenolics, many of which are thermolabiles and are susceptible to fall under heat. Oxidation, reducing potency. For example, the deteriorating oxidative of ester-based oils produces acid and water, which is probably leading to the erosion of closed components. The C-O ester bond is particularly prone to oxidative attacks, such as 2-Athylhexanol.Noxidants, such as 4,4′-methyline-busl-bists, against oxidation, but decreases after their effectiveness.

Given these weaknesses, the physics of closure is important. Common chemical storage rules emphasize tightly closed cap to prevent evaporation and dating chemicals on receipt and open shelf to track life. To open the oils. Centered oil, focused extracts, can interact unfavorable with some plastic, which is leading for erolate or leaching of undesirable compounds in oil. For their non-reactionary nature.

3.2. Seal integrity and gasket material

The integrity of seal is paramount to prevent leakage, evaporation and oxidation. Lower viscosity oil, such as citrus strands, demand strict seals and seek more strong closed design than high viscoser oils such as weightworks. The upheaval -rich volatile oils, such as peppermints, evaporation and oxidation require to reduce air risk, often requires specific lines or sealing mechanics.

The gasket material plays an important role in obtaining a safe seal. The volatile compounds of essential oils can be cheerful, rigid or cracking the rubber over time, causing brittleness and loss of elasticity. In addition, it is important to select chemically resistant elastomers:

FFKM (Perfluoroelastomer) o-rings provide high chemical resistance and are recommended for essential oils, with temperature resistance up to 625 ° F.
Nitrail (NBR) is suitable for rubber fuel and oils, providing good resistance and sealing even with temperature ups and downs.
EPDM provides good resistance to nitrogen, potassium and sodium, which is often used in water-based environment.
Silicon (VMQ) rubber is ideal for broader temperature limitations, but performs poorly with fuel, aromatic mineral oil or steam.
Viton® (FKM) is known for high chemical and fuel resistance, suitable for mineral oil, alphabetic, aromatic and chlorinated hydrocarbons.
Teflon® (PTFE) provides resistance to many chemicals and a wide temperature range, but can be difficult to seal due to its high durometer.

It is important to conduct the product/container compatibility test due to the different properties and strength of essential oils. Kol-cormers’ chemical compatibility guides can help in this selection.

3.3.Photosensitivity and UV Protection

Some essential oils, particularly expressed citrus oils, are components such as Furocormin, Koumarin and Linolul, which can cause photosensity. This means that they can induce skin damage such as redness, itching, and permanent permanent representation when exposed to permanent UV lights. The severity depends on the total percentage of phototoxic oils in the application. To reduce this, photosensitive oils must be used in small amounts (below 0.5%) in leisure-per-products for Sun-desired areas, and direct sunlight for at least 12 hours after use should be avoided.

To protect the essential oils from light-inspired decline, the packaging design is important. Amber and cobalt blue glass bottles are traditional options that effectively protect essential oils from harmful UV rays, protecting their medical properties and expands the shelf life.
