As a weekend detailer/hobbyist and engineer by day job I have some interest in the science behind these products. So, I did some searches and looked up Dr. Ghodoussi's patents, filed under the name Vahid Ghodoussi. They are quite interesting but the verbiage is a bit heavy on chemistry lingo.

Example:

"The anionic film-forming polymers are polymers having anionic groups, in particular carboxylic and/or sulfonic groups. The preferred anionic polymers employed in the compositions of this invention are selected principally from among: (1) the homo- or copolymers of acrylic or methacrylic acids or their salts and their esters and in particular the products sold under the trade names “VERSICOL F™” or “VERSICOL K™” by Allied Colloid, “ULTRAHOLD 8™” by Ciba-Geigy, the copolymers of acrylic acid and acrylamide sold under the form of their sodium salt under the designation “RETEN TM™” by Hercules, sodium polymethacrylate sold under the designation “DARVAN No 7™” by Vanderbilt, the sodium salts of polyhydroxycarboxylic acids, sold under the trade name “HYDAGEN F™” by Henkel; (2) copolymers derived from crotonic acid and their esters; (3) polymers or copolymers derived from maleic, fumaric or itaconic acids or anhydrides with vinylic or phenylvinylic or acrylic derivatives, these polymers being able to be esterified. Among these polymers, mention can be made of the polymers sold under the designations “GANTREZ™” by the GAF Corporation or “EMA ™” by Monsanto."

No links allowed here (I think) so if you search "US 6685765 B1" you can see details of one of his patents.

One thing that jumps out at me is that in a practical sense these patents are unenforceable from the perspective of someone cloning "secret sauce" because the expense of analysis would be prohibitive. The value is being able to describe from an authoritative perspective to your customer base that you are credible and not selling snake oil. As someone who has taken some upper division chemistry courses I find this entire science applied to real world automotive paint absolutely fascinating. I'm glad there is some science behind all of these products.

I have also standardized my detailing toolkit with two Optimum products now, Optimum No Rinse Wash and Wax (diluted as a quick detailer) and Optimum Car Wax (to top my toppers) for UV protection of roof/hood/trunk.

I was at SEMA one year and had a great chat with Dr G. Truly a nice guy. His knowledge is off the charts. Bright guy all around.

I read through some of those some time ago. Indeed, was a bit too much above my chemistry knowledge, but it's nice to know they did some homework.

I would definitely be interested in a "Chemistry for Detailers" online class.

Let me just say that the above appears
(to me) to be Perturbative-Theory friendly;
[not that it's nonperturbatively hostile].
