Dimethicone: You’ve probably spotted some version of it on skin and hair care labels.

As a brand that’s committed to eco-friendly practices, we wanted to set the record straight about dimethicone in skin care and hair care (and why you’ll never find it in our products).

What Is Dimethicone?

From diaper rash creams to moisturizers, hand lotions to liquid foundations, hundreds of personal care products use dimethicone for easier application. It can be used to keep products from separating.

Is Dimethicone Natural?

Dimethicone is not natural. It is a synthetic, silicone-based ingredient.

Common Dimethicone Uses

In skin care, dimethicone can be used to form a protective layer along skin and to improve water retention. Most makeup primers use some form of this ingredient (like polydimethylsiloxane) because the silicone-based polymer molecules are too large to be absorbed by skin. Instead, they leave behind a silky, slippery residue.

The same is true for dimethicone shampoo and other hair products, which result in coated hair cuticles, improved detangling, and smoothed tresses.

Is Dimethicone Safe for Skin and Hair?

According to the FDA and Cosmetic Ingredient Review (CIR), dimethicone is a safe skincare ingredient that calms irritation, minimizes redness, and protects the skin from further damage. 

Board-certified dermatologist, Dr. Julie Jackson states that dimethicone “does not interact with the stratum corneum (the top layer of the skin). It works by forming a film that prevents the loss of water through the skin that helps keep the skin moisturized. It also works as an emollient, which means that it fills the spaces between cracks in the skin.”

Though it’s an unnatural, man-made substance, dimethicone is a good chemically-inert moisturizer and safe for skin. When asked whether dimethicone is known to clog pores, Dr. Jackson concludes, “There is no evidence that dimethicone causes acne.”

Is Dimethicone Bad for Hair? 

In hair products, dimethicone is known to leave shinier tresses that are easier to detangle. However, waxy buildup can prevent water from making contact with the hair cuticle – and that can lead to dryer and/or damaged locks.

Curly and fine hair may also get weighed down, which is definitely the opposite of what you want.

Dimethicone Toxicity

Dimethicone is widely regarded as chemically and physically inert. It's also not regarded as skin irritant or sensitizer – even when it's applied at a 100% concentration.

But when it comes to dimethicone's impact on environmental issues, there are justifiable reasons to be concerned.

Is Dimethicone Bad for the Environment? 

The short answer: Yes.

Depending on the route your water takes, when dimethicone (a hydrolyzed chemical) is washed down the drain, it can feed into aquatic environments and impact fish and plant life.

The National Center for Biotechnology Information also states that “the use of low molecular weight silicones should be reduced...and the purity of high molecular weight silicones should be monitored.”
