Solubilizing agents/solvents for organic UV filters

A method of preparing a cosmetic formulation comprising:

• contacting an organic UV filter with at least one compound of the following formula
• wherein
• R, R′ are the same or different and are H, a C1-5-hydrocarbon radical, or a —O—C1-5-oxyhydrocarbon radical,
• R1, R2, R3 are the same or different and are H, or a C1-5-hydrocarbon radical,
• X, Y are the same or different and are —O—;
• —O—C(O)—;
• or —(O)C—O—,
• A is Aα which is —O—C(O)—O—;
• Aβ which is R4—CH2C(CH2—)3, or Aγ which is —C(H)-isopropyl, where R4=R4ε=—[CH2—CH(R1)]e—(Y)d—(CH2)c-Ph(R)a,
• a, b are the same or different and are 1 to 5,
• c, k are the same or different and are 0 to 5,
• d, h are 1,
• e, g are the same or different and are 0 or 1,
• f is 0 or 1,
• m is 1 to 3, and
• n is 1.
