Petrochemicals, Phthalates & Parabens in Candles: The Hidden Truth

Candles are a source of comfort, light, and atmosphere in many homes. But behind the cosy glow, not all candles are as safe as they seem. Many contain synthetic fragrance oils made with petrochemicals, phthalates, and parabens — ingredients rarely listed on the label.

These hidden chemicals can affect not only your indoor air quality but also your health and wellbeing. Let’s explore what they are, why they’re used, and the risks they carry.

Petrochemicals in Candles

What are petrochemicals?
Petrochemicals are substances derived from petroleum (crude oil). In the fragrance industry, they’re used to create synthetic aroma compounds that mimic natural scents — from “fresh linen” to “vanilla cupcake.”

Why are they used?

Cheaper than natural extraction

Stable and long-lasting

Can reproduce scents that don’t exist in nature (e.g., “ocean breeze”)

Why can they be harmful?
When candles made with petrochemical-based fragrance oils are burned, they can release volatile organic compounds (VOCs) into the air. These VOCs are associated with:

Respiratory irritation

Headaches and migraines

Exacerbated asthma symptoms

Potential long-term health risks with repeated exposure

Phthalates in Fragrance Oils

What are phthalates?
Phthalates are a group of chemicals often used in plastics, but also in fragrances as fixatives — making scents last longer and smell stronger.

Why are they used in candles?

To extend the life of the fragrance

To make the scent throw more powerful (both cold and hot throw)

Why can they be harmful?
Phthalates are recognised as endocrine disruptors, which means they can interfere with hormones in the body. Studies have linked phthalate exposure to:

Reproductive health issues

Reduced fertility

Developmental problems in children

Asthma and allergies

While some brands now market their candles as “phthalate-free”, it’s important to remember this doesn’t remove other synthetic or petrochemical ingredients still present in fragrance oils.

 Parabens in Fragrance Formulations

What are parabens?
Parabens are synthetic preservatives commonly used in cosmetics, skincare, and sometimes in fragrances to extend shelf life.

Why are they used in candles?
To prevent bacteria, mold, or yeast from growing in products that contain fragrance oils or liquid bases.

Why can they be harmful?
Parabens can mimic the hormone oestrogen, disrupting the body’s endocrine system. Some studies have suggested links to:

Increased risk of breast cancer

Fertility and reproductive issues

Skin irritation and allergic reactions

Like phthalates, some companies now advertise “paraben-free” candles. But again, this doesn’t mean the candle is natural or free from other harmful synthetics.

 Why These Labels Can Mislead

Many candle brands highlight claims like:

Vegan

Cruelty-free

Phthalate-free

Paraben-free

Soy wax base

While these labels sound reassuring, they often distract from the bigger truth: if the candle contains fragrance oils, it is still synthetic, petrochemical-derived, and potentially harmful.

The wax may be soy, the candle may be vegan, and parabens may be excluded — but the fragrance oils are still artificial. And when burned, those artificial compounds are released into the air you breathe.

 Why Transparency Matters

Candles aren’t just about how they look or smell — they’re about what you’re bringing into your home environment. If a brand isn’t open about their ingredients, it’s worth asking: why not?

Real safety comes from full disclosure, not clever marketing.

The Bryluen Botanicals Difference

At Bryluen Botanicals, we believe trust begins with honesty. That’s why our candles are:

 Made with 100% pure essential oils only

 Free from petrochemicals, phthalates & parabens

 Blended at the correct dilutions, gentle enough for pets, babies, and pregnancy

 Crafted with transparency — every ingredient listed, always

Because when the air in your home is precious, so is the light you burn.

When we say natural, we mean it.

 In Summary

Petrochemicals = petroleum-based synthetics, release VOCs.

Phthalates = fragrance fixatives that disrupt hormones.

Parabens = preservatives linked to hormone disruption and skin irritation.

“Vegan,” “soy wax,” or “paraben-free” doesn’t mean a candle is natural or safe.

True safety comes from essential oils only and full transparency.
