1963 R. R. A. Higham Handbk. Papermaking ii. 37 Because of the natural affinity of cellulose for water, paper is termed hydrophilic (water-receptive).

1971 Nature 19 Nov. 126/3 Attached to their hydrocarbon tails phospholipid molecules also..have hydrophilic head groups.

b. spec. in Physical Chemistry. [after French hydrophile (J. Perrin 1905, in Jrnl. de Chim. phys. III. 85)] : applied to a hydrosol that does not readily form a precipitate, and to a gel that readily forms a sol on the addition of water or on being warmed.
