Moisturizers effective in rinse off products?

I always see moisturizers in rinse off products, which is touted by the manufacturer, but are they really effective? For example, mineral oil sits on top of skin, would it simply rinse off or rub off when you dry yourself? Can a chemist explain. Are there any specific moisturizers effective in rinse off products?  


  • Many don't have any moisturizing benefits as they would get washed-off in wash-off products.

    Some do have some benefits because they do stick to the skin/hair even during rinse-off. 

    You should read on the classifications of moisturizers by googling "classifications of moisturizers" .
  • I have googled and there isn't much information on specifics. I'm trying to keep my skin healthy and was wondering which moisturizers are effective in surfactant solutions (rinsed off). Silicone? Triglycerides? Or should I just use a moisturizer after I shower? Seems no one is interested in giving their perspective besides you, thanks for at least answering. 
  • Well... that's partly because this is a formulatory forum. We're all chemists and product experts here. Not physicians and we can give anyone advice on how to keep anything healthy.You need to consult your physician for that. 

    I've answered your question from a purely formulatory perspective and the specificities of it are information that a chemist can collect from the right sources and understanding the material and the formula. It's not a black and white answer.
    As you asked, this goes for silicones and triglycerides. They CAN stay on the skin and they CAN be washed off. It depends on your surfactant system, type of silicones/triglyceride you use, how you formulate your product, etc.

    As @AuroraBorealis said, we are formulators, not medical professionals. We could get into big trouble doing anything that could be construed as giving medical advice. This is the reason that there is very limited information on the web about this. If you need medical advice, you should always speak with a physician.

    That said, from a formulating perspective, I have always maintained that there is a problem anytime a product is formulated to do more than one thing. Cleaning and moisturizing skin, shampooing and conditioning hair, etc.

    Any time this is a formulating goal, we inevitably have to compromise, giving up some conditioning effect in order to shampoo more effectively, for example. So, in my opinion, two products that do one thing each will always perform better than one product that tries to do two things at once. I think that cleansing products should be focused on cleaning. Moisturizing should be done by a moisturizer. In that way, a consumer can avoid the formulating compromises that degrade the effectiveness of multiple-purpose products.

    Thank you, your answer has clarified my questions. I use a gentle cleansing bar with petrolatum, and my skin is still dry in some places. Time to invest in a good moisturizer.

    Instead of using a synthetic surfactant product, try cold process soap.
