Vaseline, in its pure form, is generally not considered sticky. It's better described as greasy or oily.
While "sticky" implies an adhesive quality, where things tend to cling to the surface, Vaseline primarily acts as a lubricant and occlusive barrier. This means it creates a barrier that prevents moisture loss, which can feel somewhat tacky depending on the amount applied and environmental conditions.
Here's a breakdown:
- Composition: Vaseline, or petroleum jelly, is a semi-solid mixture of hydrocarbons. These hydrocarbons create a smooth, lubricating barrier.
- Lubrication: Because of its oily nature, Vaseline reduces friction. Sticky substances, on the other hand, increase friction.
- Occlusive Properties: Vaseline creates a barrier that prevents moisture from escaping the skin. This can lead to a slightly tacky or heavy feel, especially in humid environments or if too much is applied. However, this is different from actual stickiness where objects adhere to the surface.
- Drying Out: According to the provided reference, Vaseline doesn't dry out. This further distinguishes it from sticky substances, which often become sticky as they dry.
Therefore, while Vaseline might leave a slightly heavy or oily feeling, particularly if overapplied, it doesn't exhibit the adhesive properties associated with true stickiness.
