Constructeur
composant complémentaire de savon habituellement inorganique, qui, en référence à l'action de lavage, ajoute ses propriétés caractéristiques à celles des constituants essentiels.
Note 1:
Les constructeurs sont ajoutés à un savon pour améliorer son efficacité dans les conditions d'utilisation.
L'action des constructeurs est principalement physico-chimique et comprend une série d'effets qui se traduisent par une utilisation plus économique et une meilleure action de nettoyage du savon, en particulier dans les zones d'eau dure.
Les substances couramment utilisées comme constructeurs sont la soda, le silicate de sodium, le phosphate de sodium, le borax et les dérivés de cellulose

Explanation:
"The effects of "hard" water calcium or magnesium ions decrease with the addition of **"builders"**. The most common "builder" is sodium trimetaphosphate. The phosphates react with the calcium or magnesium ions thus keeping them in solution but away from the soap molecule. The soap molecule can then do its job without interference from calcium or magnesium ions. Other "builders" include sodium carbonate, borax, and sodium silicate, which are currently in detergents."
