A non-irritating cosmetic composition comprising:
- one or more sunscreen agents, wherein said one or more sunscreen agents is present in an amount of 1 wt % to 40 wt %, based on the total weight of said cosmetic composition;
- and
- a base composition present in an amount of 1 wt % to 6 wt %, based on a total weight of said cosmetic composition, said base composition comprising:
- 30 wt. % to 40 wt. %, based on the total weight of the base composition, of an electrolyte selected from the group consisting of sodium chloride, potassium chloride, magnesium chloride, disodium EDTA, and any combinations thereof;
- 3 wt. % to 10 wt. %, based on the total weight of the base composition, of a buffer selected from the group consisting of sodium acetate, sodium citrate, trisodium citrate, citric acid, sodium bicarbonate, sodium lactate, trisodium phosphate, disodium phosphate, sodium borate, boric acid, calcium fumarate, sodium succinate, tris-maleate, and any combinations thereof;
- 15 wt. % to 28 wt. %, based on the total weight of the base composition, of a mild preservative selected from the group consisting of esters, phenols, phenoxyethanol, paraben, methyl paraben, butyl paraben, ethyl paraben, propyl paraben, isobutyl paraben, isopropyl paraben, polyquaternium-1, benzalkonium chloride, sorbic acid, potassium sorbate, polyaminopropyl biguanidine, diazolidinyl urea, and any combinations thereof;
- 35 wt. % to 50 wt. %, based on the total weight of the base composition, of a lubricant selected form the group consisting of is selected from the group consisting of polyols, glycerin, propylene glycol, polypropylene glycol, PEG-400, PEG-8, and any combinations thereof wherein said cosmetic composition when compared to a sterile water control does not cause lacrimation and causes at most a mild stinging sensation, mild bulbar conjunctiva irritation, and mild palpebral conjunctiva irritation 30 seconds after instillation of said cosmetic composition to mammalian eyes.
