Abstract
The light stabilizer emulsion composition of the present invention includes: water; an emulsifier; and a light stabilizer and/or a UV absorber, in which components constituting the light stabilizer emulsion composition has an average particle size of 150 nm or less.
Claims11
A light stabilizer emulsion composition comprising:
- water;
- at least one of a light stabilizer and a UV absorber;
- and
- an emulsifier comprising a nonionic surfactant (A) and a nonionic surfactant (B), wherein the nonionic surfactant (B) comprises a sorbitan ester-based compound, wherein the content of the emulsifier is within a range of 40 parts by mass (weight) (exclusive) to 100 parts by mass (weight) (inclusive) with respect to 100 parts by mass (weight) of the light stabilizer and/or UV absorber, and wherein the amount of the nonionic surfactant (A) accounts for 50 to 100 weight % of the total amount of the emulsifier;
- wherein components constituting the light stabilizer emulsion composition have an average particle size of 150 nm or less.
