People often wonder, is petroleum jelly and vaseline the same thing? Well actually, the answer to this question is yes and no. The term Vaseline refers to the brand that has patented the product. Petroleum jelly is the actual substance that is the main, and only, ingredient in Vaseline lotion.
The reason why this is confusing for people is that the two terms are used interchangeably. If one is to say ‘do you have any petroleum jelly?’, the person would probably reply, ‘do you mean Vaseline?’. That is because the household name is Vaseline and Vaseline has a monopoly on products with petroleum jelly. That is not to say that petroleum jelly is not sold by other brands, but they are mainly no name brands. These generic knock offs do the same thing as Vaseline, but no one goes around saying ‘can I have some No Name Brand Petroleum Jelly for my lips?”.
