According to studies, hovewer, even 10% petrolatum can achieve almost the same mosturizing effect. The occlusive properties of petrolatum are at least twice as superior as other occlusive ingredients. This is why, in order to match the moisturizing efficacy of 10% petrolatum, a product needs to contain at least 20% of other occlusives. Our benchmark for maximum Occlusivity is 20 (and the petrolatum score is always doubled). The most occlusive product possible is 100% petrolatum (hello Vaseline Jelly).
