What Clean Formulations Mean in Personal Care Products

The term “clean beauty” is everywhere—but what does it actually mean in cosmetic formulation? As a chemist, I view clean beauty not as a rigid rulebook, but as an ingredient philosophy that prioritises safety, transparency, and sustainability.

Defining Clean Beauty in Formulation Terms

At its core, clean beauty means avoiding ingredients that are linked to health or environmental concerns, even if they are legally permitted in cosmetics. However, it does not necessarily mean all-natural, preservative-free, or toxin-free, since toxins are dose-dependent, and even water can be toxic in excess!

Hallmarks of Clean Formulations:

Exclusion of Controversial Ingredients – Many clean beauty brands avoid parabens, harmful fragrances, formaldehyde donors, and mineral oils, though the actual risks vary based on scientific consensus.

Non-Toxicity & Biocompatibility – Ingredients should be safe for long-term use and should not disrupt skin health, with a focus on non-irritating, non-sensitising options.

Transparency & Ingredient Disclosure – Full ingredient lists, sourcing details, and functional explanations are a staple of clean beauty brands.

Sustainable & Ethical Sourcing – Many clean beauty companies emphasise responsibly sourced ingredients, cruelty-free testing, and eco-conscious packaging.

Does “Clean” Mean Better?

Not necessarily. The clean beauty movement has pushed the industry towards more responsible formulation, but it is not always grounded in science. Some clean beauty brands exclude perfectly safe and effective ingredients (such as water-soluble silicones) due to misinformation.

A well-balanced clean formulation prioritises safety without compromising efficacy, ensuring that consumers receive products that are both safe and effective.
