Petrolatum
Petrolatum
Petrolatum (pronunciation: puh-troh-lay-tuhm), also known as petroleum jelly or Vaseline, is a semi-solid mixture of hydrocarbons originally promoted as a topical ointment for its healing properties.
Etymology
The term "petrolatum" is derived from the Latin words "petra" meaning rock and "oleum" meaning oil, referring to its origin from crude oil that is processed and refined.
Usage
Petrolatum is widely used in the cosmetics industry and in pharmaceuticals due to its moisturizing properties. It is a key ingredient in many skin care products, including lotions, creams, and ointments, as it helps to lock in moisture and prevent skin dryness. It is also used in hair care products to add shine and prevent frizz.
In the pharmaceutical industry, petrolatum is used as a base for many ointments and as a lubricant in certain medical procedures. It is also used in the formulation of some lip balms and cold creams.
Safety and Health Effects
While petrolatum is generally considered safe for topical use, there have been concerns about its potential health effects. Some studies suggest that petrolatum may be contaminated with polycyclic aromatic hydrocarbons (PAHs), which are potentially carcinogenic. However, the Food and Drug Administration (FDA) maintains that petrolatum used in cosmetics and personal care products is highly refined and should not pose a health risk.
