Topical spray composition to benefit skin

A system comprising:

• a) a package with a headspace of 30 to 55% based on volume of the package and capable of being pressurized to 5.2 to 10.7 bar;
• b) an exit insert, the exit insert having at least one channel, a swirl chamber and an orifice;
• and
• c) a composition comprising:
• i) a liquid emulsifier, the liquid emulsifier having an HLB from 3.0 to 7.0;
• and
• iii) a skin benefit agent, the composition is sprayable from the system at a spray rate of 0.8 to 2 g per second, has a viscosity from 500 to 4200 cps and a surface tension from 22 to 33 mN/m
• wherein the swirl chamber has a diameter, D, from 0.5 mm to 2.0 mm, the orifice has a diameter, d, from 0.15 mm to 0.4 mm, and the at least one channel has a length from 3.0 to 9 times larger than the orifice diameter, and a width from 0.7 to 5 times longer than the orifice diameter and further wherein the ratio of the orifice diameter to the swirl chamber diameter (d/D) is less than 0.45.
