Container for personal health compositions
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.
1. A product comprising:
(a) a container, wherein the container is a bottle that mitigates photodegradation of melatonin by selectively filtering or blocking light at wavelengths selected from about 470 nm to about 540 nm and from about 620 nm to about 640 nm, the container comprising:
(i) from about 98.94% to about 99.61%, by weight of the container, of a polyester;
(ii) a colorant composition comprising:
(1) from about 0.14% to about 0.30%, by weight of the container, of a first anthraquinone dye,
(2) from about 0.05% to about 0.08%, by weight of the container, of a second anthraquinone dye, and
(3) from about 0.20% to about 0.48%, by weight of the container, of titanium dioxide; and
(b) a liquid composition comprising melatonin.
2. The product of claim 1 , wherein the liquid composition is an aqueous composition comprising melatonin.
3. The product of claim 1 , wherein the container absorbs, reflects, and blocks light in the range of about 190 nm to about 750 nm with 1% or less light transmission at a container thickness of 0.5 mm.
4. The product of claim 3 , wherein the container absorbs, reflects, and blocks light in the range of about 450 nm to about 650 nm with 1% or less light transmission at a container thickness of 0.5 mm.
5. The product of claim 1 , wherein the liquid composition has a percent loss of melatonin of about 30% or less, by weight of initialmelatonin, after 100 days of exposure to factory or indoor light levels.
6. The product of claim 1 , wherein the liquid composition has a percent loss of melatonin of about 15% or less, by weight of initial melatonin, after 100 days of exposure to factory or indoor light levels.
7. The product of claim 1 , wherein the container is formed by blow molding.
8. The product of claim 1 , wherein the container has a body wall with a thickness of from about 0.1 mm to about 10 mm.
9. The product of claim 1 , wherein the liquid composition further comprises a botanical blend.
10. The product of claim 1 , wherein the container comprises the colorant composition at a let down ratio (LDR) of about 2% from masterbatch.
