Cosmetic Ingredients to Avoid | The Complete 2026 Guide

Introduction

Choosing the right skincare products can be challenging especially when cosmetic labels are full of complicated chemical names. In this guide we present a list of ingredients worth avoiding and explain why natural alternatives are a better choice for your skin and health.

1. Parabens (Methylparaben, Propylparaben, Butylparaben)

Why to avoid them: Parabens are preservatives used in cosmetics that can disrupt the hormonal balance of your body. Studies have shown their presence in breast cancer tissue. Where they are found: Creams, lotions, shampoos, and liquid soaps. Natural alternative: Products preserved with vitamin E or plant extracts like our organic liquid soap.

2. SLS and SLES (Sodium Lauryl Sulfate, Sodium Laureth Sulfate)

Why to avoid them: These aggressive cleansers can dry out the skin and cause irritation and damage the protective barrier. SLES can be contaminated with 1,4 dioxane which is a potentially carcinogenic substance. Where they are found: Shower gels, shampoos, liquid soaps, and toothpaste. Natural alternative: Soaps based on vegetable oils with natural foaming agents.

3. Phthalates (DBP, DEP, DEHP)

Why to avoid them: Phthalates are endocrine disruptors that can affect fertility and fetal development. They are often hidden under the general term perfume or fragrance. Where they are found: Perfumes, nail polish, and scented products. Natural alternative: Products scented with natural essential oils or completely fragrance free products.

4. Formaldehyde and Formaldehyde Releasers

Why to avoid them: Formaldehyde is a carcinogenic substance that can cause allergic reactions and skin irritation as well as respiratory problems. Where they are found: Nail polish, hair straighteners, and certain antibacterial soaps. Ingredients that release formaldehyde: DMDM Hydantoin, Diazolidinyl Urea, and Quaternium 15.

5. Triclosan and Triclocarban

Why to avoid them: These antibacterial agents can contribute to the development of antibiotic resistant bacteria and disrupt hormone functions while harming the environment. Where they are found: Antibacterial soaps, toothpaste, and deodorants. Natural alternative: Plain soap and water is just as effective at removing bacteria.

6. Synthetic Dyes (CI plus number)

Why to avoid them: Many synthetic dyes are derived from petroleum and can cause skin irritation and allergic reactions. Some are potentially carcinogenic. Where they are found: Colored soaps, shampoos, and makeup.

7. PEG (Polyethylene Glycol)

Why to avoid them: PEG compounds can be contaminated with ethylene oxide and 1,4 dioxane which are carcinogenic substances. They also weaken the natural protective barrier of your skin. Where they are found: Creams, lotions, and facial cleansers.

8. Mineral Oil and Petroleum Jelly

Why to avoid them: These petrochemical products clog pores and can be contaminated with carcinogenic substances known as PAHs. They do not nourish the skin but merely create an occlusive layer. Where they are found: Creams, lip balms, and baby products. Natural alternative: Vegetable oils like olive oil or coconut oil and shea butter.
