The answer is – yes!

According to the Cosmetic Ingredient Review (CIR) expert panel, isoparaffins are safe to use in cosmetic formulations. The concentration of isoparaffins used in beauty products ranges from 0.0001% (C13-14 Isoparaffin) to 90% (Isodedocane). The expert panel did not find any evidence of carcinogenic potential from exposure to isoparaffins in cosmetics (1).

What if you inhale it when you use hair sprays and deodorants? Well, the average particle diameter in aerosol sprays has a mean of  ~38 µm, and 99% of the isoparaffin particle diameter range between 10–110 µm. Hence, anything less than 10 µm is respirable. This means isoparaffins in aerosols are non-respirable (1).

In animal studies, isoparaffins caused skin sensitization and ocular irritation. However, in human studies, these chemicals, whether used alone or in formulations, were found tolerable and not classified as irritants, sensitizers, phototoxici  Any specific chemical or substance that causes toxic effects on the skin when exposed to excess sunlight. , or photosensitizersi  A class of chemicals that increase sensitivity to light and make the skin irritable or inflamed. (2).

Only isohexadecane (undiluted) induced mild skin irritation in patients. However, it did not induce irritation when used in 10% concentration (in petrolatum).

Other than this,

  • The FDA permits using a synthetic form of isoparaffin hydrocarbons to coat fruits and vegetables (3).
  • On a scale of 1 to 10 (10 being the most harmful), the Environmental Working Group (EWG) rates C13-14 isoparaffin as 1 in terms of safety (4).

However, according to dermatology, there are some safety concerns regarding the possible contamination of isoparaffins.

Side Effects And Risks Associated With Isoparaffin

Since isoparaffin is derived from petroleum, there are chances of 1,4-dioxane contamination, which may cause skin irritation and allergies, and the FDA considers it as a potential human carcinogen. However, an evaluation of products to trace the presence of 1,4-dioxane  by the International Cooperation on Cosmetics Regulations (ICCR) reported that the chemical levels are within the acceptable margin. Therefore, the expert panel concluded that trace levels of 1,4-dioxane (less than 10 ppm) in cosmetic products are safe (5), (6).
