What are the best bottles for essential oils?

The best bottles protect essential oils from degradation and ensure chemical compatibility. While dark glass is traditionally favored for UV protection, opaque PET plastic bottles, including our 35% and 50% PCR options, also effectively shield oils from light. We offer these in common sizes like 5ml, 10ml, 15ml, and 30ml, with standard 18-400 or 20-410 neck finishes, available with no minimum order quantity.

Can you put essential oils in plastic bottles?

Yes, many essential oils can be safely stored in specific types of plastic bottles, particularly PET. Our PET bottles, including those with 35% or 50% PCR content, are suitable for most essential oils, especially when diluted or for short to medium term storage. It is important to avoid plastics like PVC or PS, which are not compatible.

Why are essential oil bottles dark?

Essential oil bottles are dark to protect the oils from harmful UV light exposure, which can degrade their therapeutic properties. Opaque PET plastic options, such as our 35% and 50% PCR bottles, effectively block these light waves, preserving the oil's integrity. This ensures your product maintains its potency and aromatic compounds.

What size essential oil bottles should I buy?

The ideal size depends on your product line and intended use. For essential oils, common sizes include 5ml, 10ml, 15ml, and 30ml, while 60ml and 120ml are popular for carrier oils or larger volume products. Our PET bottles, available with 35% or 50% PCR content and standard 18-400 or 20-410 neck finishes, can be purchased with no minimum order quantity.

§Buying Guide

Choosing a Size

1 oz works for retail, therapeutic blends, and DTC singles. 2 oz suits value sizes, professional aromatherapists, and spa retail. Both sizes come in boston round and cosmo shapes.

Caps and Closures

Essential oil bottles need tight sealing to prevent evaporation. A smooth lid or euro dropper insert gives drop by drop dispensing. A disc top cap works for blends that the customer pours rather than drops. Both the 20-410 and 24-410 neck finishes are available.

Formula Compatibility

This is the most important section for essential oils. PET tolerates diluted essential oil blends (carrier oil base with 2 to 10% essential oils). Pure, undiluted essential oils, especially citrus oils (lemon, orange, grapefruit) and tea tree, can interact with PET at full concentration over time. If your product is pure essential oil, test a filled bottle for 90 days before committing to production quantities. Amber PET is strongly recommended because it helps reduce light degradation.
