    hello,
    does anyone here knows a raw material that can keep melted bar soap liquid after being melted?

    Use KOH vice NaOH in the saponification process.

    @Microformulation, we wanted to make use of our scrap and make it body wash.

    @johnb we melted the soap bar with some water at high temperature but it goes back to its soap characteristic after some time. we wanted to convert it to body wash at least.

    You ought to formulate using synthetic detergents rather than soap for this purpose.
    I doubt that you will get a successful product by using soap.

    Soaps made with sodium hydroxide do not have the solubility needed to make a liquid soap.  Soaps make with Potassium Hydroxide, TEA and some other bases would be much more appropriate for this purpose.  You could combine and press your scraps with machinery to create soap bars with it though!

    It is possible that you could make a bodywash with surfactants, and use your soap scraps to thicken it, instead of using salt, but it seems like a lot of work for minimal reward.

    Why not just make soap powder from your scraps?

    @Bobzchemist @David08848 @johnb thank you all for your thoughts but i have proposed to make powder detergents on our scrap and then dont like the idea because of too many process involved.
