According to the invention there is provided a compound of Formula (I) in which: A is a C.sub.2-8 alkylene group; R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently selected from hydrogen, C.sub.1-4 alkyl, C.sub.2-4 dihydroxyalkyl in which the carbon atom attached to the nitrogen atom does not carry a hydroxyl group and no carbon atom is substituted by two hydroxyl groups, or R.sup.2 and R.sup.3 together form a C.sub.2-6 alkylene group which with the nitrogen atom to which R.sup.2 and R.sup.3 are attached forms a heterocyclic ring; X.sub.1, X.sub.2 and X.sub.3 are independently selected from hydrogen, hydroxyl, NR.sup.1-A-NR.sup.2R.sup.3R.sup.4+(Z.sup.m−).sub.1/m, for halogeno amino, C.sub.1-4 alkoxy or C.sub.2-8 alkanoyloxy; and (Z.sup.m−).sub.1/m is an anion of charge m; or a derivative in which the group NR.sup.1 is quaternarized.

A container for personal health compositions with melatonin. The container has a polyester and a colorant composition with at least two dyes and a pigment. The container can filter out the wavelengths of visible light that contribute to the photodegradation of melatonin during storage in normal factory or home light conditions.
