P&G scientist on Two-in-1 conditioner
I just want to ask on why scientist of other <wbr>company at that time have not thought of suspending silicones in shampoo to make two in one shampoo (1980s). How did P&G scientist thought of it while Unilever’s, Alberto Culver’s, and L’oreal’s scientist did not thought about it? These companies spend much on R&D budget and on hiring PhDs. Yet, they let P&G thought of such novel idea at that time while they did not.

It was not simple technology - early versions left hair pretty ugly. P&G worked on it for years.

I believe you are mixing some things. Silicones have been used in suspension for decades now. If you pick up for instance an UL shampoo, you’ll see that they have silicone oils along with a carbomer as a suspending agent. That technology is old and very common. What’s unique to P&G’s shampoos is the use of a LGN to both conditiong and stabilize silicone oils (that’s why you don’t find a polymeric suspending agent in their shampoos). To be fair, L’oreal had tried to mimic this approach, but for what I remember from its patent, I believe they couldn’t replicate the same manufacturing process (P&G use a very specific colloid mill to make the LGN while L’oreal mix the ingredients altogether without the premix).
