Whether you’re blending for skincare, aromatherapy, or diffuser use, measuring by “drops” can feel imprecise—until you understand the science behind it.

One drop of essential oil equals approximately 0.05 mL, though viscosity and dropper type can slightly affect this.

That means every time you blend, formulate, or dose, each drop carries weight—literally. At PauPack, we help beauty and wellness brands calibrate this tiny measurement for big product consistency. Let’s break down how drops translate to mL and grams, and why it matters in your product development.

How Much Oil Is 1 Drop?

A drop isn’t always just a drop—unless you’re using the right tools.

On average, one drop of essential oil measures 0.05 milliliters when dispensed from a standard Euro dropper.

Why This Can Vary:

• Oil Thickness: Thicker oils (like vetiver or sandalwood) may produce smaller drops than lighter oils (like lemon or tea tree).

• Dropper Style: Euro droppers produce smaller, more consistent drops compared to pipettes or orifice reducers.

• Temperature: Warmer environments thin the oil, which may result in larger drops.

Oil Type	Drop Size (Approx.)	Drop Count per 1mL
Light Oils (Lemon, Tea Tree)	0.05 mL	~20
Medium Oils (Lavender, Frankincense)	0.045–0.05 mL	~20–22
Heavy Oils (Myrrh, Sandalwood)	0.04 mL	~25

This is why at PauPack, we recommend using precision droppers with calibrated flow restrictors—especially for brands formulating at scale or aiming for regulatory consistency in EU or FDA markets.

What Is the 30/50/20 Rule for Essential Oils?

Scent layering starts with a formula—not a free-for-all.

The 30/50/20 rule means using 30% top notes, 50% middle notes, and 20% base notes in a blend to create balanced aroma and longevity.

Practical Breakdown:

• Top Notes (30%): First to hit the nose, quick to fade. (e.g., Lemon, Peppermint)

• Middle Notes (50%): Heart of the blend, moderate longevity. (e.g., Lavender, Rose)

• Base Notes (20%): Last the longest, anchor the scent. (e.g., Patchouli, Vetiver)

Let’s say you're making a 2ml blend (40 drops total):

• 12 drops Top

• 20 drops Middle

• 8 drops Base

By using this rule, you're not just making it smell good—you’re making it last. PauPack clients often ask us for packaging that matches the pace of aroma development. Our droppers and roller bottles are designed to control flow and reduce flash evaporation, preserving the scent profile longer.

How Much Is 25 Drops of Essential Oil?

Tiny quantity, but mighty impact.

25 drops of essential oil is approximately 1.25 mL when using a standard drop size of 0.05 mL.

This amount is ideal for:

• A 5% blend in a 25mL carrier (strong therapeutic massage oils)

• A single-use diffuser refill

• A DIY perfume roller (10ml bottle at 25% dilution)

Drop Count	Total Volume (mL)
10 drops	0.5 mL
20 drops	1.0 mL
25 drops	1.25 mL
30 drops	1.5 mL
40 drops	2.0 mL

When creating small-batch blends, especially for testing or samplers, accuracy matters. That’s why PauPack offers 5ml and 10ml dropper bottles with built-in reducers—ensuring that your 25 drops are consistent from bottle to bottle.

How Many Drops of Essential Oil Are in 1g?

Weight and volume don't always match up—especially with oils.

There are approximately 20–25 drops of essential oil in 1 gram, depending on the oil’s density.

Why It’s Not Exact:

• Different oils = different densities
  For example:

  • Water = 1g/mL

  • Essential oils = 0.85–0.95g/mL typically

So:

• 1g of lavender oil (density ≈ 0.88 g/mL) = ~23 drops

• 1g of sandalwood oil (denser) = ~20 drops

Oil Type	Density (g/mL)	Drops per Gram
Lavender	0.88	~23
Lemon	0.84	~24
Sandalwood	0.96	~20

At PauPack, we work with brands that label products by both volume and weight, depending on their export markets. That’s why our glass bottles are tested not just for volume tolerance, but also for compatibility with viscosity and density variation in essential oils.

Conclusion

One drop may seem small—but getting it right ensures safety, scent quality, and formulation accuracy. At PauPack, we bottle every drop with precision so your brand delivers consistency with confidence.
