Liposhield HEV Melanin

INCI: Melanin
Product Category: AbsorberLiposhield HEV Melanin is a fractionated melanin compound, designed to be used topically as an additional environmental defense against High Energy Visible light (HEV). Liposhield® HEV Melanin is designed to shield the skin from high energy blue/violet visible light. This ingredient may help to prevent premature aging and hyperpigmentation. It is tailored specifically to absorb light in the range of 400-500 nm wagelengths and was made to have a molecular weight that is estimated to be 5,000 to 10,000 Daltons and will not penetrate healthy, intact skin.
Liposhield HEV Melanin is soluble in water. For usage in aqueous application, the pH should be adjusted and held between 5.5 – 6.9. At higher pH levels, the melanin will darken. It should be added to emulsions after emulsification at 45°C with medium propeller mixing. It will impart a yellowing effect to oil-in-water emulsions, which can be mitigated with the addition of dyes, resulting in pale pastel formulations. Incorporation into water-in-oil or water-in-silicone emulsions may partially mask the yellowing effect. The ingredient is UV stable when exposed to light in formulations.
This material is not suitable for gel formulations, as colourless formulations can not be obtained. It is also not compatible with cationic ingredients, resulting in the formation of a precipitate. It is heat sensitive and therefore should not be heated above 50°C. Incorporation into formulations at temperatures below 45°C is recommended.
