Disodium phosphate is a special kind of salt that is made by combining two kinds of smaller particles called sodium and phosphate. These particles are really small and we can't see them with our eyes, but they are really important in making things like food and cleaning products.
Disodium phosphate is mostly used in food to help keep it fresh and to change its texture. It can also be used in some cleaning products to help clean things more effectively.
Think of it like making a cake: you have different ingredients like flour, sugar, and eggs that you mix together to create the cake batter. Disodium phosphate is like one of these ingredients that you may not see, but it helps make the cake taste better and stay fresher for longer.
So overall, disodium phosphate is just a small, important particle that helps make things we eat and clean more effective and better for us.
