How To Choose The Best Bulk Essential Oils

Picking the right bulk essential oil is about more than just grabbing the biggest bottle. You want oil that stays fresh, smells true, and works across your diffuser, DIY soaps, and cleaning recipes without fading.

Check for “100% Pure” and Undiluted Claims

Some bottles labeled as “bulk” are pre-diluted with carrier oils or artificial fillers to cut costs. You want a label that explicitly says 100% pure and steam-distilled — that means you get the real plant essence, not a watered-down version.

Consider the Bottle Material

Essential oils are sensitive to light and heat. Dark glass (amber or cobalt) blocks sunlight. Aluminum bottles shield against light and temperature shifts. Plastic jugs are lighter and unbreakable but should be UV-resistant (designed to block ultraviolet rays). Pick the material that fits your storage setup and usage pace.

Match the Scent to Your Use Case

Not every oil works for every project. Peppermint is energizing and excellent for DIY cleaning. Lavender is floral and relaxing for diffusers. Eucalyptus has a crisp, camphoraceous smell (a sharp, medicinal aroma like Vicks VapoRub) great for air fresheners. Rose is softer and used in perfumes and soaps. Buy the scent that matches what you actually do with it.

In‑Depth Reviews

★ Best Overall

1. NaturoBliss Peppermint Essential Oil – 16 fl oz

Our pick — over 4.5★ from 16,500+ verified ratings; the strongest balance of quality and price.

4.6 / 5 RatingGlass Bottle

The 16-ounce peppermint with a lifetime warranty and the highest rating in this lineup.

With a 4.6 out of 5 rating from over 16,800 reviews, this NaturoBliss peppermint oil is the most-reviewed bottle here. It is 100% pure, steam-distilled, and undiluted. The 16 fl oz size sits between the smaller typical bottles and the massive 32 oz jugs — a smart middle ground if you want bulk without committing to a gallon-style purchase. The dark glass bottle with a UV-colored coating protects the oil, and the free European dropper cap lets you dispense a drop at a time.

At 1.01 pounds, this bottle weighs half of the GreenHealth Eucalyptus 32 oz (2 pounds) — a 2.0x difference in weight. The volume gap is also 2.0x (16 fl oz vs 32 fl oz). So the NaturoBliss is a more manageable size for someone who uses peppermint regularly but does not need industrial quantities. The brand backs it with a lifetime warranty — if you are ever unsatisfied, they replace or refund.

Buyers highlight the strong, authentic peppermint scent that works well for relieving muscle tension when diluted and for boosting energy in a diffuser. Just remember the safety warning: not for internal use, keep away from children and pets, and always dilute with a carrier oil (a neutral oil like coconut or jojoba) for topical use.

Top Features

  • Highest customer rating at 4.6 / 5 from over 16859 ratings
  • Lifetime replacement or refund warranty
  • European dropper cap for pinpoint dispensing

Limitations

  • 16 fl oz is half the volume of the 32 oz bulk options
  • Glass bottle, while protective, can break if dropped

Why pick this: you want a proven, highly-rated peppermint oil with a dropper cap and a lifetime guarantee, in a manageable bulk size.

Not for you if: you need the absolute lowest cost per ounce — the 2-pack GreenHealth Peppermint beats it on volume.

2. GreenHealth Eucalyptus Essential Oil – 32 fl oz

Aluminum Bottle32 oz Bulk

The 32-ounce aluminum giant built for heavy daily use without losing potency.

This is the biggest single-bottle option in the lineup at 32 fl oz (fluid ounces, about 946 ml). You get a full 2 pounds of oil that is steam-distilled (extracted using steam instead of chemicals) and undiluted, so every drop carries that crisp camphoraceous eucalyptus scent. The aluminum bottle protects the oil from light and heat without any risk of breaking if you drop it. Buyers report the aroma stays fresh all the way to the last drop, which matters when you are buying this much at once.

Compared to the NaturoBliss Peppermint at 16 fl oz, this GreenHealth bottle holds a 2.0x larger volume (32 fl oz vs 16 fl oz). It also weighs 2 pounds versus NaturoBliss at 1.01 pounds — you get double the oil for a single bulk purchase. The eucalyptus scent works equally well in a diffuser, DIY cleaning spray, or homemade candle.

One thing to note: eucalyptus is potent. A few drops in a diffuser fill a whole room, so this massive bottle will last most households many months. If you want an energizing scent for cleaning or air freshening, this is the buy-it-once choice.

What Stands Out

  • Largest single-bottle volume at 32 fl oz
  • Aluminum container blocks light and heat without glass fragility
  • 100% pure, steam-distilled, undiluted oil

Consider Before Buying

  • Eucalyptus scent is strong — not for those sensitive to camphor notes
  • No dropper cap; you need to pour or transfer for small amounts

Buy this if: you want the largest pure bulk bottle with a protective aluminum case, perfect for diffuser refills and homemade cleaners.

Who should skip it: anyone needing a milder floral scent — eucalyptus is sharp and medicinal.

Best Value

3. GreenHealth Peppermint Essential Oil – 2 Pack (16 fl oz Each)

2-Pack BulkPlastic Jugs

Two 16-ounce jugs of pure peppermint that together give you a full 32 ounces of bulk power.

This 2-pack delivers a total of 32 fl oz of steam-distilled Mentha arvensis peppermint oil, split into two sturdy white plastic jugs. The UV-resistant plastic (designed to block ultraviolet light that degrades oil) is lighter than glass and unbreakable — a practical choice if you move the oil around a workshop, spa, or home crafting area. The scent is a strong, natural menthol aroma that cuts through grease and stale air, making it a favorite for DIY cleaning sprays and diffusers.

Unlike the single 32 oz Eucalyptus from GreenHealth which comes in a single aluminum bottle, this peppermint option splits the volume into two separate jugs. That means you can keep one sealed while using the other, extending the shelf life of the unopened portion. It weighs less than two separate glass bottles would, too, which buyers mention makes handling easier during pouring.

Be sure to dilute this oil before applying to skin — it is highly concentrated. The manufacturer recommends a carrier oil and a patch test before use. Owners mention the peppermint punch is excellent for invigorating diffuser blends and homemade soaps.

Why It Works for Bulk

  • 32 fl oz total across two unbreakable UV-resistant jugs
  • Strong menthol aroma ideal for cleaning and energizing diffuser mixes
  • One jug stays sealed while the other is in use — keeps oil fresher longer

Watch Out For

  • Plastic jugs lack the prestige of glass, though they are more practical for heavy use
  • Not suitable for direct skin contact without dilution

Best for: high-volume peppermint users — spas, workshops, or anyone making bulk cleaning products.

Look elsewhere if: you prefer glass storage or need a single-bottle format.

Budget Champion

4. Handcraft Blends Lavender Essential Oil – 16 fl oz

Floral ScentDIY Friendly

A full 16 ounces of lavender for less than most 4-ounce specialty bottles.

Lavender is the most versatile floral essential oil for home use — it blends well with eucalyptus, peppermint, sweet orange, rosemary, and tea tree oils. This Handcraft Blends bottle gives you 16 fl oz (1.26 pounds) of lavender oil that works in diffusers, candle making, soap making, and homemade sprays. The 4.4 out of 5 rating from 722 reviews indicates consistent quality at a budget-friendly price point.

The fresh, floral aroma is warm and crisp, making it a popular choice for aromatherapy massage when diluted with a carrier oil. Customers note that this bulk size is perfect for frequent DIY projects where you go through oil quickly — you will not run out mid-batch. It comes in a glass bottle, so store it away from direct sunlight to keep the scent profile stable over time.

Compared to the FRAOIL Rose oil (also 16 fl oz but more expensive), the Handcraft Lavender is a more affordable entry point into floral bulk oils for everyday use. The lighter, more familiar lavender scent makes it a safer gift for friends who are new to essential oils.

Standout Qualities

  • 16 fl oz bulk lavender at a competitive price point
  • Blends smoothly with many other essential oils
  • Great for candle, soap, and spray DIY projects

Potential Drawbacks

  • Only 722 ratings — a newer product with less long-term review history
  • Glass bottle without a dropper cap; use a separate dropper for small amounts

Grab this for: affordable bulk lavender that you can pour into multiple DIY creations without worrying about cost.

skip it if: you want a premium, single-note lavender from a heritage brand — this is a solid all-purpose bulk oil, not a niche artisan product.

Best for DIY Floral

5. FRAOIL Rose Essential Oil – 16 fl oz

Rose ScentAmber Glass

A 16-ounce bottle of rose oil that brings a spa-like floral aroma to your diffuser and crafts.

Rose oil is typically sold in tiny bottles due to its concentrated nature and higher cost. This FRAOIL bottle breaks that pattern with a full 16 fl oz (480 ml) of rose-scented essential oil. It comes in an amber glass bottle with a flow control stopper — not a dropper, but a pour-control mechanism that works for larger amounts. The oil is suitable for aromatherapy diffusers, homemade candles, soap making, bath bombs, and perfumery.

At 1.61 pounds, this is the heaviest of the 16 oz bottles here (heavier than NaturoBliss at 1.01 lbs and Handcraft Lavender at 1.26 lbs). The brand describes the upgraded formula as refined through a rigorous standardized process. Buyers looking for a rose scent that is not cloying note that it pairs well with lighter citrus oils in DIY candle recipes. The elegant packaging also makes it a potential gift for birthdays, Christmas, or Mother’s Day.

One trade-off: the rating of 4.2 out of 5 from 853 reviews is the lowest in this roundup, and a handful of reviewers mention the scent is not as complex as premium rose absolute oils. For pure bulk rose at this size, however, it is a rare find. If you specifically want rose for perfumery, this gives you the volume to experiment freely.

Why You Want It

  • Rare 16 oz bulk size for rose oil — usually sold in tiny bottles
  • Amber glass protects oil from UV degradation
  • Versatile for diffusers, candles, soaps, bath bombs, and perfumery

Heads Up

  • 4.2 / 5 rating is the lowest among these five picks
  • Flow control stopper, not a dropper — less precise for small doses

Reach for this if: you want a large-format rose oil for DIY candle, soap, or perfume projects without paying for tiny glass vials.

pass on it if: you demand an ultra-premium, complex rose absolute scent — this is a solid bulk aromatic oil, not a niche artisan extraction.

Understanding the Specs

Bottle Volume & Container Type

Bulk essential oils typically start at 16 fl oz and go up to 32 fl oz or more. The container matters more than you might think: dark amber or cobalt glass blocks UV light (ultraviolet radiation that degrades oils over time). Aluminum bottles offer the same light protection with added durability — they will not shatter if knocked over. UV-resistant (ultraviolet-resistant) plastic jugs are lighter and unbreakable, ideal for workshop or spa environments where glass is risky. Match the container to where you store and use the oil.

100% Pure & Undiluted

Look for “100% pure” and “steam-distilled” on the label. This tells you the oil is extracted from the plant directly without solvents and is not cut with cheaper carrier oils like jojoba or fractionated coconut oil. Undiluted oil is stronger and more versatile because you control how much to dilute based on the project — a diffuser needs just a few drops, while soap making might need more. An oil that is already diluted limits your control over the final strength.

FAQ

How many drops are in a 16 fl oz bottle of essential oil?
A standard essential oil dropper delivers roughly 20 drops per milliliter (ml, a metric volume unit). At 16 fl oz (approximately 473 ml), you get around 9,460 drops per bottle. A 32 fl oz bottle holds roughly 18,920 drops.
Can I use bulk essential oils directly on my skin?
No. Bulk essential oils are highly concentrated and must be diluted with a carrier oil (like coconut, jojoba, or almond oil) before topical application (applying to the skin). Undiluted oil can cause skin irritation or sensitization (a skin reaction that worsens with repeated contact). Always do a patch test first.
How long does a 16 fl oz bottle of essential oil last in a diffuser?
Most diffusers use 3 to 5 drops per session. At 4 drops per session, a 16 fl oz bottle gives you roughly 2,365 sessions. If you diffuse once daily, the bottle lasts well over six years — so bulk sizing truly is a long-term purchase.
What is the difference between glass, aluminum, and plastic bottles for essential oils?
Glass (especially dark amber or cobalt) offers great UV protection but is breakable. Aluminum blocks both light and heat effectively and is shatter-resistant. UV-resistant (ultraviolet-resistant) plastic is lightweight and unbreakable but may not seal as tightly over many years. For oils you use frequently, plastic or aluminum is practical. For long-term storage, glass is best.
Can you mix different bulk essential oils together?
Yes. Blending oils is a common practice in aromatherapy and DIY crafting. Lavender blends well with eucalyptus, peppermint, sweet orange, rosemary, and tea tree oils. Start with small test batches to find a ratio you like before scaling up.
How should I store bulk essential oil to keep it fresh?
Store sealed bottles in a cool, dark place away from direct sunlight and heat sources — a cupboard or closet works well. Keep the cap tight to prevent oxidation (a chemical reaction with oxygen that can ruin the scent). Avoid storing in the bathroom where humidity and temperature fluctuate. Aluminum and dark glass bottles provide built-in protection.
Are bulk essential oils safe to use around pets?
Certain oils (including peppermint, eucalyptus, and tea tree) can be toxic to cats and dogs, especially in concentrated forms. Always consult a veterinarian before diffusing essential oils around pets. Keep bottles securely closed and out of reach of animals. This applies to all bulk essential oils.
What does “steam distilled” mean for essential oils?
Steam distillation is a process where steam passes through plant material, causing the oil glands to release their volatile compounds (scent-carrying chemicals that evaporate easily). The steam and oil vapor then cool and separate. Oils labeled “steam distilled” are extracted without chemical solvents, preserving the natural chemical profile of the plant.
Can I use bulk essential oils for cleaning?
Yes. Eucalyptus and peppermint oils are popular for DIY cleaning sprays, laundry boosters, and all-purpose cleaners due to their antibacterial properties and fresh scents. Mix a few drops with water, vinegar, or castile soap. Always test on a small surface first to ensure the oil does not stain or damage the material.
Which bulk essential oil scent is best for beginners?
Lavender is widely considered the most beginner-friendly scent. It is familiar, floral, and relaxing. It blends well with almost any other oil, works in diffusers and DIY projects, and is less likely to be overwhelming than strong scents like peppermint or eucalyptus. The Handcraft Blends 16 oz lavender is a solid entry point.

Final Thoughts: The Verdict

For most buyers, the best bulk essential oils winner is the GreenHealth Eucalyptus 32 fl oz because it delivers the largest single-bottle volume in a protective aluminum container with pure, steam-distilled quality. If you want a versatile floral option for DIY projects and diffusers, grab the Handcraft Blends Lavender 16 fl oz. And for peppermint lovers who need total bulk, the standout is the GreenHealth Peppermint 2-pack that splits 32 ounces into two practical jugs.
