Chemicals to Avoid in Skincare Products

Phthalates

Phthalates are commonly used in fragrances and can also be found in other skincare products. They are often used to help fragrances adhere to the skin and to soften plastics. However, phthalates have been linked to a variety of health issues, including reproductive harm and developmental issues. They are also believed to be endocrine disruptors, which can affect hormone levels in the body.

To avoid phthalates, it’s important to look for products that are labelled “phthalate-free.” Choose products with natural fragrances or essential oils, and consider making your own skincare products using natural ingredients.

Sodium lauryl sulfate (SLS) and Sodium laureth sulfate (SLES)

SLS and SLES are harsh surfactants commonly found in skincare products such as soaps, shampoos, and body washes. They are effective at removing dirt and oil from the skin, but they can also strip the skin of its natural oils, leading to irritation and dryness. SLS and SLES can also be contaminated with other harmful chemicals, such as 1,4-dioxane, which is a potential carcinogen.

To avoid SLS and SLES, look for products that are labelled “SLS-free” or “SLES-free.” Consider switching to natural soap alternatives such as castile soap or glycerin soap, which are gentler on the skin.

Formaldehyde

Formaldehyde is a common preservative used in skincare products, especially in nail polishes and hair straightening treatments. It is a known carcinogen and can cause skin irritation and allergic reactions. Formaldehyde can also be released by other preservatives, such as quaternium-15, which can be found in many personal care products.

To avoid formaldehyde, look for products that are labelled “formaldehyde-free.” Consider using natural preservatives such as grapefruit seed extract or vitamin E.

Triclosan

Triclosan is an antimicrobial agent commonly used in hand sanitisers, soaps, and other personal care products. It has been linked to hormone disruption and bacterial resistance. Triclosan can also react with chlorine in tap water to form chloroform, a potential carcinogen.

To avoid triclosan, look for products that are labelled “triclosan-free.” Consider using natural alternatives such as tea tree oil, which has natural antibacterial properties.

Polyethylene glycol (PEGs)

Polyethylene glycol, also known as PEG, is a synthetic compound derived from petroleum. It is commonly used in skincare products as an emulsifier, to help mix oil and water-based ingredients together. However, PEGs can be contaminated with harmful chemicals, such as ethylene oxide and 1,4-dioxane, which are potential carcinogens.

PEGs can also strip the skin of its natural oils, leading to dryness and irritation. In some cases, PEGs have been linked to skin allergies and dermatitis.

To avoid PEGs, look for products that are labelled “PEG-free” or “petroleum-free.” Consider using natural emulsifiers such as beeswax or lecithin, or choose products that use natural alternatives such as plant-based glycerin.

Mineral oil

Mineral oil is a common ingredient in many skincare products, including moisturisers and baby oil. It is derived from petroleum and can clog pores, leading to breakouts and other skin issues. Mineral oil has also been linked to skin irritation and can interfere with the skin’s natural ability to eliminate toxins.

To avoid mineral oil, look for products that are labelled “mineral oil-free.” Consider using natural alternatives such as coconut oil or jojoba oil, which are non-comedogenic and provide similar moisturising benefits.
