What is the Dirty Dozen in Cosmetics?

The term Dirty Dozen refers to a list of twelve common chemical ingredients in cosmetics that can cause serious harm to human health and the environment. Many of them are:

• Hormone disruptors
• Potentially carcinogenic
• Toxic to the nervous system
• Hazardous water pollutants

Getting to know them is the first step towards a cleaner, safer, and more conscious routine.

1. VHA or BHT: Preservatives with Hidden Risks

These compounds are used as preservatives to prevent oxidation and extend the product's shelf life. They are found in creams, lipsticks, and makeup.

The problem? They are known endocrine disruptors that can affect the hormonal system, causing severe imbalances and even tumors.

Furthermore, they pollute the water and damage marine ecosystems.

Why avoid them?

• They disrupt the hormonal system and can cause illnesses.
• They are persistent pollutants in the environment.
• There are natural alternatives without these risks.
  
  

2. Dyes Derived from Coal Tar

Ingredients such as paraphenylenediamine are used in hair dyes and products with intense color.

Although visually appealing, these dyes are linked to neurotoxicity and cancer , as well as being highly polluting to water and marine life.

Main negative impacts :

• They can damage the central nervous system.
• Studies link them to chronic diseases and cancer.
• Its use irreversibly contaminates aquatic ecosystems.
  
  

She prefers natural dyes or those certified as safe.

3. Kokamida DEA or Cocamide DEA: Deceptive foam

It is found in many shampoos, soaps and gels , as it provides lather and a creamy texture.

But this ingredient can form nitrosamines , highly carcinogenic substances , during its manufacture or when it reacts with other chemicals.

Associated risks :

• It generates carcinogenic compounds during its decomposition.
• It contaminates bodies of water and affects aquatic species.
• It is present in everyday products, increasing exposure.
  
  

Avoid products with DEA ​​in their ingredient list.

4. Dibutyl Phthalate: A danger in your nail polish

Used to give flexibility to enamels, this plasticizer is an endocrine disruptor that can affect fertility and increase the risk of hormone-related tumors.

Furthermore, like many ingredients in the Dirty Dozen , it also poses an environmental threat by entering the water and harming marine life.

Reasons to eliminate it from your routine :

• It affects the female reproductive system.
• Associated with risk of tumors.
• It contributes to the pollution of the aquatic ecosystem.
  
  

Opt for 3-free, 5-free or toxic-free polishes.

Why should we worry about these ingredients?

These ingredients not only affect your health, they also pollute rivers and oceans , and accumulate in your body through daily use.

Constant exposure can lead to chronic illnesses, hormonal imbalances, and skin problems.

Being mindful of what we use is an act of self-care, but also an environmental decision.

How to avoid the Dirty Dozen?

You don't need to be a chemist to identify these ingredients. Here are some simple recommendations:

1. Read product labels: Avoid names you just learned.
2. Research and support clean beauty brands: Look for those that work with safe and sustainable formulas.
3. Choose natural or certified products: Organic, vegan, toxin-free.
4. Get your information from reliable sources: Blogs, communities, hair and skin health specialists.
