A builder is the part of a detergent that deals with water hardness — the single largest drag on cleaning performance in most water supplies.
Without one, a significant share of the surfactant is consumed neutralising calcium rather than removing soil, and the redeposition that follows shows up as greying and film.

What a builder does Calcium and magnesium in the wash water react with surfactant and take it out of play. A builder sequesters that hardness first, so the surfactant is free to lift soil.
Phosphate builders STPP is the benchmark — sequestration, alkalinity buffering and anti-redeposition in one material. TSPP and SHMP cover formulations tuned to different solubility and pH profiles.
Phosphate alternatives Where phosphate is restricted, carbonate plus a sequestrant such as EDTA, and zeolite-type materials, carry the hardness load instead.
