Startup Idea : Immuno-surpression personal care line

It would be a great idea for someone to start a personal care brand designed for people with suppressed immune systems. It could include extra parabens (the most effective preservative). It should not have plant extracts because some people may be sensitive and take every consideration as to the needs of people with suppressed immune function. This could be a major hit as many people experience this from common chemo treatment and anti-inflammatories. Some companies use special bottle caps to minimize bacteria, air and dirt getting into the product as well. There are some containers which do not allow air into the product at all.
