Lavender is one of the most trusted and widely used essential oils in the world. From calming bedtime rituals to luxury soaps and perfumes, lavender shows up everywhere. Yet behind the label, not all lavender oils are the same.
Two types often cause confusion: pure lavender oil and lavender 40/42. If you’ve ever wondered about lavender 40/42 vs pure lavender, you’re not alone. Understanding the difference can help you choose the right oil for wellness, skincare, or product formulation — and avoid paying for something that doesn’t match your needs.
This guide breaks it all down clearly and honestly.
What Is Pure Lavender Oil?
Pure lavender oil is considered the gold standard in aromatherapy and natural wellness.
Definition
Pure lavender oil is a 100% natural essential oil steam-distilled from Lavandula angustifolia flowers, without chemical modification or standardization.
How It’s Made
• Harvested from lavender plants grown in specific climates
• Steam-distilled to preserve the plant’s full chemical profile
• Bottled without altering its natural composition
Chemical Makeup
Pure lavender oil contains naturally occurring levels of:
• Linalool
• Linalyl acetate
• Dozens of trace compounds
These levels vary based on:
• Soil quality
• Climate
• Altitude
• Harvest timing
This natural variation is what gives pure lavender its depth and therapeutic complexity.
Aroma Profile
• Soft
• Floral
• Slightly herbal
• Multi-layered
Each batch may smell subtly different — a sign of authenticity, not inconsistency.
Common Uses
• Aromatherapy
• Diffusers
• Skincare and body oils
• Relaxation and sleep rituals
Understanding Lavender 40/42
Lavender 40/42 is a standardized lavender oil, created primarily for fragrance consistency.
Definition
Lavender 40/42 is lavender oil that has been processed or blended to achieve a fixed chemical profile, typically:
• ~40% linalool
• ~42% linalyl acetate
How It’s Made
• Starts with natural lavender oil
• Goes through rectification or blending
• Adjusted to meet a precise aroma standard
It may come from:
• A single lavender species that’s modified
• Multiple lavender oils blended together
Purpose
The goal of lavender 40/42 is consistency, not therapeutic complexity.
Common Uses
• Perfumes
• Soaps and candles
• Bath bombs
• Home fragrance products
For brands, this ensures that every batch smells exactly the same.
Pure Lavender Oil vs 40/42: Key Distinctions
Let’s break down pure lavender oil vs 40/42 in the areas that matter most.
Natural Variation vs Standardization
Pure lavender oil
• Reflects nature
• Contains a full spectrum of plant compounds
• Varies slightly from batch to batch
Lavender 40/42
• Engineered for uniformity
• Focuses on two dominant aroma molecules
• Delivers the same scent every time
This is the core of the lavender 40/42 vs pure lavender debate.
| Feature | Pure Lavender Essential Oil | Lavender 40/42 Essential Oil |
|---|---|---|
| Source | Steam-distilled from Lavandula angustifolia | Derived from natural lavender oils, then standardized |
| Processing | Minimal, unaltered | Rectified / blended for consistency |
| Chemical Profile | Naturally variable | Fixed (~40% linalool, ~42% linalyl acetate) |
| Aroma | Complex, soft, herbaceous | Clean, bright, sweet, uniform |
| Batch Consistency | Varies by harvest | Highly consistent |
| Therapeutic Use | ✅ Ideal | ⚠️ Limited |
| Skin Use | ✅ Preferred (proper dilution) | ⚠️ Less common |
| Fragrance Use | ⚠️ Inconsistent | ✅ Excellent |
| Cost | Higher | Lower |

Aroma and Chemical Profile
Pure lavender oil
• Deeper, richer, more nuanced
• Retains natural therapeutic compounds
• Often softer and less sharp
Lavender 40/42
• Cleaner, brighter, sometimes sharper
• More linear scent profile
• Fewer trace compounds
This difference becomes obvious in diffusers and skin applications.
Cost of Pure Lavender vs 40/42
One of the most common questions is about the cost of pure lavender vs 40/42.
Pure lavender oil costs more because:
• Requires high-quality crops
• Is often single-origin
• Cannot be “corrected” after distillation
Lavender 40/42 is cheaper because:
• Oils can be blended from multiple sources
• Chemical adjustment reduces waste
• Large-scale production is easier
This explains why is lavender 40/42 cheaper than pure lavender oil.
Lower cost doesn’t mean “bad” — it means different priorities.
Cost Comparison: Why Lavender 40/42 Is Cheaper
| Factor | Pure Lavender Oil | Lavender 40/42 |
|---|---|---|
| Raw material sourcing | Single-origin, crop dependent | Multiple sources allowed |
| Yield flexibility | Low | High |
| Post-processing | None | Adjusted for efficiency |
| Waste reduction | Minimal control | Optimized |
| Production scale | Smaller | Large-scale friendly |
| Price point | Premium | Budget-friendly |
Key takeaway:
Lavender 40/42 costs less because it’s optimized for manufacturing, not because it’s “lower quality.”
