Wetting agent

Are wetting agent ingredients that increase the spreading ability and penetration of formulation?

If yes then what are some good wetting agents?

Spreading and penetration may be a result of wetting but that’s not their main effect. As their name implies, they wet stuff (other ingredients, surfaces etc.) by means of different modes of action. Usually, they are surface active and reduce surface tension and hence reduce contact angle.

Wetting agents: All soaps, all detergents, and most emulsifiers, and many solvents. ‘Good’ depends on the use.

Spreading: everything with a low viscosity and a high spreading value such as light ester oils, low molecular weight hydrocarbons, cyclic silicones, and many solvents.

Good penetration: KY gel :smiley:

KY is like WD-40: if screwing becomes more work than pleasure because the old hole is getting a bit rusty, real men use WD-40… KY is for pussies.
