Phillips produced milk of magnesia and other pharmaceuticals at his Glenbrook firm, which incorporated in 1885 as the
Charles H. Phillips Company. After Phillips' death of
apoplexy in New York on 29 October 1888, his four sons ran the corporation until 1923, when it was acquired by
Sterling Drug, Inc. ''Phillips' Milk of Magnesia
is still manufactured today. The final blue bottle was filled in 1976, when production at the Glenbrook plant was phased out. Sterling, and its Phillips' Milk of Magnesia'', was purchased by
Bayer in 1994. ==References==
