9,820,920 B2; L'Oreal, Paris, has patented a process for making a sunscreen composition that is comprised of an aqueous phase; an oil phase comprising at least one cosmetically acceptable oil; at least one sunscreen active; an emulsifier system comprising at least one ionic surfactant, at least one non ionic surfactant having an HLB of greater than or equal to about 14; and at least one nonionic surfactant
having an HLB of less than or equal to about 10; and combining those ingredients.

The surfactant used in this experiment was a nonionic surfactant
comprising 10% alkyl polyglycoside, 7% EO/PO block copolymer and 83% water that was applied at a constant rate of 1000 ml per ha per irrigation.
Nanoemulsions, containing 10% oil and 10% surfactant, were formed using a spontaneous emulsification method with a 10% oil phase (grape seed oil and orange oil) and 10% surfactant --a commercial polysorbate 80, which is a nonionic surfactant
and emulsifier often used in foods.
5) In this study, two different surfactants were studied: one nonionic surfactant
, an alkyl phenol ethoxylate (Surfactant A), and an anionic surfactant, an amine salt of an alkyl benzene sulfonate (Surfactant B).
The following figures show the level of ADBAC exhausted as a function of the concentration of the co-formulated nonionic surfactant
, polyethylene-oxide 12 (Figure 4) and small quat, tetramethyl ammonium chloride (Figure 5).
The nonionic surfactant
polyethylene glycol tert-octylphenyl ether (Triton X-114) was used as an extracting agent.
NIS-EA, the first product to launch in the Eco Advantage platform, is a premier nonionic surfactant
that has shown up to a 20% improvement in herbicide efficacy in extensive testing.
For comparison, a partially fluorinated nonionic surfactant
(ATA-I074) based on poly(fluorooxetane-block-polyethylene oxide-block-fluorooxetane) was donated by Omnova Solutions.
For example, Qiao and Easteal (6) studied the interaction between nonionic surfactant
and poly (ethylene glycol), Fishman and Eirich (7) and Murata and Arai (8) studied the interaction between SDS and poly (vinyl pyrrolidone).
Instead it is made with essential oils, a coconut-based cleaning agent (the nonionic surfactant
alkyl polyglucoside), filtered water and citric acid.
