Blends contain industrial chemicals of individual interest to AICIS.

A blend in Chemintro is made by linking chemicals via their blend proportions. They are most useful for saving data entry effort when a number of different products have largely the same set of ingredients.

Tagged Flavour/fragrance blend chemicals, however, are categorised under different rules for typically low (<=1%) concentrations in end-use products.

Chemintro handles blends as follows:

All blends:

• A named blend may have its own CAS number and chemical properties
• Any chemical in Chemintro becomes a blend if it has one or more chemicals linked, each with its individual blend proportion
• Any single chemical ingredient may simultaneously be in numerous blends
• Inserting a blend in a product at a particular proportion, inserts its linked chemicals pro rata in their correct proportions
• If a product has an existing chemical ingredient in common with one in the blend, the proportion in the product of that chemical will be automatically increased

Flavour/fragrance blends:

• A blend becomes a Flavour/fragrance blend if one or more of the abovementioned links are tagged accordingly
• Flavour/fragrance categorisation rules apply to chemicals in Flavour/fragrance blends
