Okay kiddo, let me explain what alginic acid is in simple terms.
Imagine you love making sandcastles on the beach, and you need something to help keep your castle together. Alginic acid can do that for you!
Alginic acid is a natural chemical that comes from something called “brown seaweed”. It’s like a glue that helps the seaweed stay together in the water. Scientists found out that alginic acid can also help keep other things together, like when you mix it with some other ingredients in food, medicine or even in cosmetics.
So, when you play with sand, you might need water to make it stick together, right? It's the same with alginic acid. It mixes with other ingredients and helps them stick together!
I hope that helps you understand what alginic acid is all about.
