1. Food & Healthcare Ingredients

• Nutritional Supplement: Dicalcium phosphate dihydrate is a good source of calcium and phosphorus, which are essential for bone and teeth health. It's often added to foods like cereals, flour, and dairy products to increase their nutritional value. 
• Anti-caking Agent: In powdered products like milk, spices, and baking powder, it helps prevent clumping, making them easier to use and extending their shelf life. 
• Dough Conditioner: In baking, it improves the texture and rise of dough, resulting in better baked goods like bread, cakes, and cookies.

2. Pharmaceuticals

• Tablet Excipient: Dicalcium phosphate dihydrate acts as a binder and filler in tablets, improving their structure and ensuring they hold together well. It also aids in the flow of ingredients during tablet manufacturing. 
• Calcium and Phosphorus Source: It's a common ingredient in dietary supplements and multivitamin formulations, providing essential calcium and phosphorus for maintaining healthy bones and teeth. 
• Buffering Agent: In antacid formulations, DCPD help neutralize stomach acid, providing relief from heartburn and indigestion.

3. Animal Healthcare

• Feed additive: Dicalcium phosphate dihydrate (DCPd) is a mineral supplement commonly added to animal feed to provide essential calcium and phosphorus for growth, bone development, and overall health, particularly in livestock like cattle and poultry.

4. Agrochemicals

• Fertilizer: Dicalcium phosphate dihydrate is a key ingredient in fertilizers, providing readily available calcium and phosphorus to plants.
• Soil Amendment: It improves soil fertility by supplying essential nutrients that plants need for healthy growth.
• Crop Specificity: Dicalcium phosphate dihydrate is especially beneficial for crops like fruits, vegetables, and legumes that have high calcium and phosphorus demands.
• Starter Fertilizers: It's often included in starter fertilizer blends to promote early root development and rapid plant growth.

5. Personal Care

• Bulking Agent: It adds volume and structure to cosmetic formulations, particularly in powdered products like face powders and blushers. 
• Opacifying Agent: It helps to make products less transparent, contributing to the desired opacity and color of cosmetic items. 
• Abrasive: In oral care products like toothpaste, it acts as a mild abrasive to help remove plaque and stains from teeth.

6. Performance Chemicals

• Preparation of other Calcium Phosphates: Dicalcium phosphate dihydrate is a common precursor for other calcium phosphate compounds, including hydroxyapatite (HAp). It can be converted to other forms through controlled heating or by reacting with different ions in solution.
