Delivery system

My research is focusing on developing a delivery system for cosmetics. In every cosmetics product, there should be a carrier or delivery system to deliver the active ingredients into certain parts or layers of the skin for it to take effect. Active ingredients are the ones which responsible for the benefits such as anti aging, antioxidant and others. Apart from basic ingredients, these active ingredients are the main ingredients for a beneficial cosmetics to reach it's target.

The benefits from the active ingredient take effect in different parts of skin or in different ways. It may be in the epidermis or the dermis. That is why we must create a specific system or carrier for a specific active ingredient for it's efficiency. There are different types of delivery system used in cosmetics industry such as emulsion, microparticles and the famous ones, liposomes and nanoparticles. These delivery systems were often used as drug delivery systems in pharmaceutical industry but has grown in the cosmetics industry as well.

For my research, i'm using charged nanoparticles. The purpose is to develop a carrier that retain the active ingredients in a wash-off product. Surfactants in cleansing products normally wash away together all the active ingredients before it could penetrate into skin. Because our skin is naturally negatively charged, that is why positively charged carrier is suggested to be developed so it can be attracted to the skin and not being washed away.

The end product will be a facial cleanser with the beneficial ingredient still retained and penetrated into skin maybe without needing to use a moisturizer after cleansing. Hopefully.
