Uncovering the Truth About Dimethicone: Misconceptions and Benefits

First off, have you ever wondered where silicones actually come from?

Silicones can be found in nature, but they don’t exist in isolation. They are typically combined with other elements, such as in SiO2 (silica). This molecule, which contains SiO2, is present in materials like sand, rocks, and crystals.

To isolate silicon (Si), the SiO2 molecule undergoes a process involving carbon and high heat, known as a (carbothermic reaction).Once isolated, silicon is combined with other molecules to create ingredients that offer various benefits for the cosmetic industry.

In this article , we’re focusing on Dimethicone, also referred to as PDMS, which is the most commonly used silicone in cosmetics.There’s a good reason for its popularity in the industry: it provides numerous advantages in formulations and is often the secret behind what consumers seek in their products, from sensory experiences to visual appeal.

Now, let’s address some of the misconceptions!

Some people believe that Dimethicone penetrates the skin, is harmful, causes cancer, or is an allergen.

These claims are unfounded because the molecule is too large to penetrate our skin or hair, and it doesn’t interact with our skin’s mechanisms. This is why it’s known for creating a barrier on the skin and hair, similar to how petroleum works as an occlusive agent.

Does Dimethicone suffocate the skin?

This can be a bit confusing since terms like “film,” “occlusive,” and “non-water soluble” are often used to describe silicones, making it easy to imagine a buildup on our hair. However, let me clarify why this isn’t a problem. While Dimethicone is indeed non-water soluble and forms a film, it is also vapor permeable. This means that your skin can still breathe; you can sweat, and your hair follicles won’t get clogged. Think of it like Gore-Tex fabric: it blocks liquid water from getting through but allows water vapor (sweat) to escape, preventing discomfort. So, in essence.Consider Gore-Tex material; it effectively blocks liquid water from getting through while allowing sweat (water vapor) to escape, thanks to the fabric (dimethicone). This creates a comfortable experience. So, it’s essentially a perfect balance, right?

Now, let’s talk about build-up.

The only downside to dimethicone might be the build-up it can cause. But don’t worry, I have a simple solution! Using a good clarifying shampoo with surfactants like sulfates (which I’ll cover in another blog) can help remove the dimethicone. As for your skin, there’s no need to stress since we wash our skin much more frequently than our hair, so build-up isn’t an issue. Plus, the formulations for skincare and haircare are different, leading to varying benefits.

In general, silicones are beneficial in skincare due to their sensory advantages, providing a smooth feel, glossiness, and enhancing the skin barrier. They also make products easier to spread. For both hair and skin, silicones act as protectants against UV rays and repel water.

When it comes to hair, opinions on silicones can differ based on hair types. They are particularly favoured by those with curly hair, coils, or tend to have frizz. Many people appreciate the results they get from using silicones, although build-up can be a concern. It’s all about establishing a good hair care routine.

I hope this eases any worries you might have had about using silicones in your hair or skincare products! There’s no need to be concerned unless you have an allergy, which is quite rare.
