Abstract
A paprika emulsified dye preparation exhibiting a red color is provided. Specifically, a paprika emulsified dye preparation, which contains a paprika dye, an oil-based solvent, water, and an emulsifier, and has the following characteristics: a color density per mass percent of an oil phase is 1500 CV or more; a volume-based median diameter (D50) of emulsified particles is 1 to 3 μm; and a hue is 25 to 34 is provided.
Claims8
A paprika emulsified dye preparation, comprising a paprika dye, an oil-based solvent, water, and an emulsifier, and having the following characteristics:
- a color density per mass percent of an oil phase is 1500 CV or more;
- a volume-based median diameter (D50) of emulsified particles is 1 to 3 μm;
- and
- a hue is 25 to 34.
A method for producing a paprika emulsified dye preparation, comprising:
- a step of mixing a paprika dye and an oil-based solvent, thereby preparing an oil phase having a color density per mass percent of the oil phase of 1500 CV or more;
- and
- a step of mixing the oil phase and an aqueous phase containing water and an emulsifier, thereby preparing emulsified particles having a volume-based median diameter (D50) of 1 to 3 μm.
