What is dimethicone, exactly? You might spot it on skin and hair care labels, but chemical names like “polydimethylsiloxane” can be difficult to decipher when you’re pressed for time.

As an eco-friendly brand, Puracy wants to set the record straight about dimethicone in skincare and hair care – and you’ll never find it in our products.   

What Is Dimethicone?

If you've ever used a makeup primer, it probably had some form of dimethicone (ie. polydimethylsiloxane) in it. Since the molecules of silicone-based polymers are too large for the skin and hair to absorb, these products leave behind a silky/slippery layer.

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, thus keeping the skin moisturized. It also works as an emollient, filling the spaces between cracks in the skin.”

The result? Shinier-looking and smoother-feeling skin and hair.

What Is Dimethicone Used for?

Hundreds of personal care products use dimethicone for a more seamless application, including diaper rash creams, moisturizers, hand lotions, and liquid foundations. Most hair care companies use silicones and dimethicone to coat the hair cuticle and make detangling easier.

Is Dimethicone Bad for Skin?

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.

We consulted with Dr. Jackson on this topic, and she agreed that – even 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 concluded, “There is no evidence that dimethicone causes acne.”

How to Avoid Dimethicone in Shampoo & Conditioner

Historically, there have beenvery few eco-friendly hair products which provided the same results as their synthetic counterparts.

After years of R&D with expert chemists and testers, Puracy Natural Shampoo and Conditioner are rare examples of dimethicone-free hair products that leave all hair types moisturized, bouncy, and shiny.

Introducing LexFeel N5

While reformulating our shampoo and conditioner, the biggest change came from the inclusion of Lexfeel N5. This 100% sustainable and biodegradable emollient seamlessly replicates the effects of both dimethicone and silicone. We’re proud to be one of the first companies to use this plant-sourced ingredient in our unbelievably effective hair care line.

Pro tip: Like any natural hair care regimen, it may take between 2 and 4 weeks for follicle build-up to disappear. 

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.”

Because it isn’t biodegradable – and the current environmental research isn’t ideal – Puracy focuses on providing natural alternatives. From our biodegradable plant extracts to organic essential oils, we know that the right balance of natural skincare ingredients can perform just as well as synthetic counterparts.
