We have tested using a rinseless methodology, but using a variant of a traditional shampoo. Honestly... It was very hard to see a difference between this and using a 'rinseless' product.
There is a lot of variation in shampoos. There are very few 'soaps' these days, this is basically archaic and I'd be horrified to hear of any detailing brand selling g such a product. Generally we will be working with synthetic surfactants and misc other odds and ends. As it happens, many of these will be classified as 'polymers'. I have never been able to discover exactly what optimum are meaning with their use of the polymer terminology. I'll have to dig into this to see if the patents divulge what optimum is actually using, but I'd doubt it. That being the case, optimum would really struggle to argue technical superiority and it is potentially plausible that the tech used by some others is comparable.
