Few side effects are associated with PEG 100 stearate when used in beauty and personal care products. However, it is recommended that PEG stearates are not applied to damaged skin; using the ingredient on skin that is cut or inflamed increases the risk of potential side effects, which are usually limited to skin irritation. Discontinuing use of the product featuring PEG 100 stearate is a simple way to eliminate any noted side effects. However, in the vast majority of users, PEG 100 stearate produces no noticeable side effects, simply making the products in which it is used more effective.
