2. The compound or a salt thereof according to claim 1 ,
wherein the compound of Formula (1) is a compound of Formula (1)-3,

(in the formula, R 21 is a linear or branched saturated or unsaturated hydrocarbon group having 10to 17 carbon atoms).

3. The compound or a salt thereof according to claim 1 ,
wherein R 1 and R 2 each independently is a hydrogen atom or a linear or branched acyl group having 14 to 18 carbon atoms.

4. The compound or a salt thereof according to claim 2 ,
wherein R 21 is a linear or branched saturated or unsaturated hydrocarbon group having 15 to 17 carbon atoms.

5. The compound or a salt thereof according to claim 1 ,
wherein the compound of Formula (1) is a compound of Formula (1)-301 or (1)-302

6. The compound or a salt thereof according to claim 1 ,
wherein the salt of the compound is a salt formed by the compound becoming a cation together with an inorganic anion or an organic anion or a salt formed by the compound becoming an anion together with an inorganic cation or an organic cation.

7. The compound or a salt according to claim 1 ,
wherein the salt of the compound is a salt formed by the compound becoming a cation together with one or more anions selected from the group consisting of a hydroxide ion, a nitrate ion, a sulfate ion, a carbonate ion, a bicarbonate ion, a halide ion, a formate ion, an acetate ion, a citrate ion, a tartrate ion, an oxalate ion, a fumarate ion, anions of saturated or unsaturated chain fatty acid having 3 to 20 carbon atoms, anions of carnitine and derivatives thereof, anions of hydroxy citric acid and derivatives thereof, anions of ascorbic acid, and anions of ascorbyl phosphoric acid and derivatives thereof.

8. The compound or a salt thereof according to claim 1 ,
wherein the salt of the compound is a salt formed by the compound becoming an anion together with one or more cations selected from the group consisting of a sodium ion, a potassium ion, a calcium ion, a magnesium ion, a zinc ion, an ammonium ion, carnitine, and cations of carnitine derivatives.

9. An external agent for skin comprising:
the compound or a salt thereof according to claim 1 .

10. A cosmetic comprising:
the external agent for skin according to claim 9 .

11. A food additive comprising:
the compound or a salt thereof according to claim 1 .

12. The compound or a salt thereof according to claim 1 , wherein R 1 and R 2 each independently is a hydrogen atom or a linear or branched acyl group having 11 to 18 carbon atoms, a hydrocarbon group bonded to a carbonyl carbon of the acyl group is a saturated hydrocarbon group, and at least one of R 1 and R 2 is the acyl group.
