Good day! I just want to ask if large companies ( P&G, L'OREAL, UNILEVR etc. ) create their own non-ionic emulsifier blend such as MONTANOV, COSMOWAX ( for creams or lotion ) or do they buy it from other companies? Do they prefer to buy the single components in the blend and mix the individual components or they buy the blended versions? I am asking since the emulsifier blends sold to my country is way higher as compared to buying the individual components of the non-ionic emulsifier blend. I don't understand why the blended emulsifier is way too expensive as compared to buying the individual components in the blend and mix on your own.
