Flavour and fragrance blends

[Mike Dewhirst]

AICIS Guidance

AICIS guidance is absolutely clear that no matter what chemicals are in a low-risk flavour or fragrance blend, they are only interested in individual chemicals being introduced in the blend.

The word blend is synonymous with mixture albeit understood to be a sub-mixture within a mixture - or formulation.

Chemintro current design

Individual chemicals need to be separately introduced. This design should not be changed for low risk flavour or fragrance blends because it satisfies current AICIS rules and guidance.

The saving grace for the current design is that it is simple and the same chemical can be used in multiple products delivering proper information management.

It is vital that this design feature does not change

Chemintro redesign impetus

Data entry in Chemintro becomes, however, quite onerous for formulators who work with multiple blends of chemical mixtures in varying proportions.

There is a Chemintro redesign impetus to ease data entry by using prepared blends of chemicals to formulate products directly instead of, or together with, individual chemicals.

Redesign requirements

• A chemical needs to be selectable to construct a blend

• Different blends may contain the same chemicals in different proportions

• A blend needs to be selectable alongside chemicals in a product

• Different blends may be selected for the same product

• A blend must transform into a set of actual chemicals making up a product

• Any particular chemical can only appear once in a product

Blend user interface

• Main Menu section labelled Blends with Add a new Blend

• Enter a Blend name unique to that company

• In a sub-section Add another chemical

• Select an existing Chemical as the new ingredient

• Enter the Precise proportion in the blend

• Repeat adding chemicals until the blend is complete (<= 100%)

Product user interface

• Add or select a Product

• Enter or update product related data

• Scroll down and Add another Product-chemical proportions

• Select a Chemical or a blend, enter Precise proportion and Max concentration and [Save]

Result of entering a Blend

If a Blend was saved with specific proportion and max concentration, it will add all the constituent chemicals and recalculate all chemical volumes.
