HYDROFLUOROCARBON 134A

Description

Hydrofluorocarbon 134a (HFC-134a), also known as 1,1,1,2-tetrafluoroethane, is a synthetic compound widely used in various industries, including cosmetics and skincare. In dermatological applications, it primarily functions as a propellant in aerosol formulations. This colorless, non-flammable gas has a low boiling point of -26.3°C, making it ideal for creating fine, consistent sprays.

HFC-134a is valued for its stability, non-reactivity with other ingredients, and low toxicity profile. It has replaced chlorofluorocarbons (CFCs) in many applications due to its significantly lower ozone depletion potential. In skincare products, it enables the even distribution of active ingredients and helps maintain product integrity.

While generally considered safe for topical use, HFC-134a may cause mild skin irritation or cooling sensations in some individuals due to its rapid evaporation. It's important to note that this ingredient is not absorbed by the skin and does not contribute to the therapeutic effects of skincare formulations. Environmental concerns have led to efforts to reduce HFC-134a usage, with some companies exploring alternative propellants. When formulating or selecting products containing HFC-134a, consider both its functional benefits and potential environmental impact.
