How do I use suitability constraints to limit or ban ingredients based on their hazard or property?
'Regulatory Item Property Limit' allows you to target a property of an item, often a hazard, and limit it to a level or ban it altogether. These kinds of restrictions are typically customer requests.
People often use this type of constraint to ban or limit raw materials with any CMR hazards, or to limit skin sensitisers. You can also limit based on other properties, e.g. Prop 65 or food allergens. Some examples follow:
To create a constraint which 'bans' ingredients which are Carcinogen's, first consider which properties you want to target. You need to apply the constraint to the properties which you want to limit / ban, for example CAR 1A, CAR 1B, CAR 2. To ban these:
Regulatory item Property Limit with a value of zero
Apply the constraints to properties CAR 1A, CAR 1B, CAR 2 (not the = variants)
To create a constraint which to limit the amount of skin sensitsers to below 0.1% it's a similar constraint, but with a non-zero limit:
Regulatory item Property Limit with a value of 0.099
Apply the constraints to properties SS1, SS 1A and SS 1B (not the = variants)
Note that 'Regulatory Item Property Limit' targets the properties of items based on the regulatory composition (exploded/flattened to regulatory composition). There is a 'Physical Item Property Limit' which targets the properties of physical items (exploded/flattened to physical composition)
