  • Best “second skin” product
  • Offers tremendous play time
Background Information

There are many active ingredients used in cosmetics which deliver consumer perceivable benefits. However, there is an increasingly greater need to improve product feel and aesthetics as well as provide some level of activity. One way to make a formulation feel better and be perceived as offering longer wear properties is to use a higher molecular weight material, which will remain on the skin’s surface without being absorbed or worn off. Lonza Personal Care has identified certain polymers that form uniform films on the surface of the skin with an excellent after-feel. We call this our “Second Skin” technology, where a polymeric protective film, which is capable of entrapping pigments and actives, resisting wear and feeling good, is left on the skin’s surface. Conventional cleansers (soaps, etc.) can remove these polymeric films, but they are water-resistant and demonstrate good durability lending a persistent, soft, emollient feel. Our Gel Base technologies have gone through a number of evolutions over time. Each product has a distinct set of characteristics, which can be utilized by the formulator to give their products unique qualities.
