The Truth About Reactive Ingredients

Reactive Ingredients in Nail Polish


Today, more consumers than ever are taking a closer look at the ingredients in their favorite cosmetic products. That’s because many commonly used ingredients can actually have adverse effects on your health and overall appearance. Reactive ingredients, for example, can become sensitizers, over time causing a person to develop contact allergies or dermatitis.

What are 'Reactive Ingredients'?

Can’, of course, is the operative word here as not all reactive ingredients are skin sensitizers and vice versa. To put it technically, reactive ingredients are substances that are unstable and react with other substances, thus causing them to form yet another substance. This means a reactive ingredient is more likely to be an allergen than one that is unreactive, so a product that is free of reactive ingredients is likely to be your safest bet.

What are 'Skin Sensitizers'?

A skin sensitizer, incidentally, is any chemical that causes a substantial portion of people or animals to develop an allergic reaction in normal skin tissue after repeated exposure. This condition is also called chemical hypersensitivity and can lead to long term damage. See, when humans are sufficiently exposed to a skin sensitizer, they can develop what’s known as a contact allergy. Once in that sensitized state, further exposure can lead to a disease called allergic contact dermatitis. At that point, chemicals that are not sensitizers but still irritants may further cause or aggravate allergic reactions in sensitized individuals.

Common Skin Sensitizers

Most known skin sensitizers commonly found in nail care products are monomeric and oligomeric acrylates and methacrylates; this includes the cyano acrylates and methacrylates used as nail glues in nail enhancement products. They can cause irritation when coming into contact with the skin and, after prolonged or repeated contact, the immune system can become compromised, causing an allergic reaction. Once sensitized, only a trace amount of the chemical is needed for the allergic response to flare back up.

Allergen-Causing Chemicals

The EU regulation known as REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) offers a list of these allergen-causing chemicals, including acrylates, methacrylates, formaldehyde, isocyanates, anhydrides, amines, thiocarbamates, lactones, peroxy compounds, hydrazines, and aldehydes.
