How does detergent break surface tension

WebSurface tension is at the origin of the overpressure existing in the interior of drops and bubbles. Δ p = p inside - p outside = γ (1/ R + 1/R') = γ C. The increase in hydrostatic pressure Δ p that occurs upon traversing the boundary between two fluids is equal to the product of the surface tension γ and the curvature of the surface C = (1 ... WebOct 26, 2016 · Detergent breaks surface tension by disrupting the bond between water molecules. This is because detergent has a polar and non-polar heads on its molecules. The hydrogen and oxygen molecules in water form hydrogen bonds, which form a type of skin on the surface of the water. This skin is strong enough to support the weight of very light …
