Citric Acid (Anhydrous) is a natural occurring fruit acid that can be used in DIY home cleaning, cosmetics and personal care products. Citric acid is fully biodegradable and is the most widely used organic acid and pH-control agent. It’s safe for the planet’s water system, and contains no harsh toxins that would pose a threat to your family’s health.
Citric acid exists in two forms as anhydrous form and monohydrated form. The difference between anhydrous and monohydrate citric acid is that the anhydrous citric acid has no water of crystallisation whereas the monohydrate citric acid has a water molecule associated with one citric acid molecule.
Keep out of reach of children.
Don't add too much citric acid to hair products like shampoos, it can change your hair colour.
