Regulations :

This clearcoat for foodstuffs is qualified as “direct contact" and meets the requirements of Regulation 10/2011 concerning plastic materials and articles intended to come into contact with foodstuffs according to OM3* tests carried out by an external laboratory with reports (test 2021).

The standards and tests ensure that the substances contained in the materials of its products do not migrate into the food in quantities that could present a hazard to the consumer, or alter the chemical composition of the food or its organoleptic properties.

Hardness and adhesion properties are achieved after 48-72 hours at 20°C.

TESTS AND APPLIED METHODOLOGY FOR TESTING FOOD-SAFE CLEARCOAT VA1005

The methodology was derived from Regulation 10/2011 and its subsequent amendments. Overall migration under OM3 conditions (2 hours, 70 ºC).

Simulants : For all types of food, Simulants A (10% ethanol), B (3% acetic acid), and D2 (isooctane and 95% ethanol) are used.

DESCRIPTION OF THE METHOD FOR DIRECT FOOD-SAFE CONTACT CLEARCOAT

Overall migration is performed using simulants (A, B) under standard OM3 conditions, which include food-safe contact conditions involving hot filling (contact) and/or heating up to a temperature T where 70 ºC ≤ T ≤ 100°C for a maximum time t = 120/2 ^ [(T-70) / 10] minutes.

Repeated use:

In the case of products intended for repeated contact with foodstuffs, the migration test(s) must be carried out three times on the same sample, using a different portion of food simulant each time.

Certification of Compliance

Certifying the food-safe compliance of the clearcoat and certifying that a clearcoat is suitable for food-safe contact solely based on overall migration requires preliminary study and evaluation.

As the clearcoat manufacturer, along with our specialized and independent partner laboratory, we provide guidance and conduct this study. We can cover all or part of the costs associated with migration testing and certification.

In accordance with European Regulation 10/2011 and its subsequent amendments, there are different testing options and conditions (OM0 to OM7) that correspond to specific migrations. Standard test conditions for determining overall migration vary.

The direct food-safe contact clearcoat from Stardust is tested under OM3 conditions.

Overall migration of a coating under standard OM3 conditions for all types of food (simulants A, B, and D2): The simulants used for studying all types of food are defined as A, B, and D2. E (dry simulant) is not used, as it is assumed that a greater amount migrates in aqueous or fatty environments than in dry contact. The compliance report refers to overall migration (<10 mg/dm2) according to the standard. The test does not focus on specific migration but rather on overall migration.

Preliminary Study and Compliance

Before conducting migration tests, it is necessary to determine the appropriate test conditions. Depending on the intended use, packaging, and temperature, different test conditions are specified. Examples include :

• Packaging for fruits and vegetables : 40 ºC for 10 days of contact.

• Plastic cup : 70 °C to 100 °C for a duration of 15 to 30 minutes.

Therefore, to determine the applicable test conditions (duration and temperature), we rely on the intended use of the product being studied, as specified in Regulation 10/2011 (Annex 3, Table 2 of 10/2011, (Specific assignment of simulants to food categories), which helps in choosing the appropriate test for the food product and its use.)

In this context, as in the example of the plastic cup, the worst-case conditions are used, meaning the cup may be used for drinking a liquid at either room temperature or boiling hot. In each case, one must select a planned use with the criteria deemed appropriate.

To be provided by the company placing the product on the market :

> Test conditions (according to the intended use defined by the company)

> Simulants (according to the foods it will come into contact with)

The choice of simulant is also determined based on the specific foods with which the product is likely to come into contact. While it is true that simulants A, B, and D2 are chosen for all types of foods (simulant E for dry contact), it should be specified by the company in each case.

Migration testing for paints and clearcoats in contact with foodstuffs :

Migration testing is a tool used to determine if certain substances migrate and in what quantities.

The Declaration of Compliance is a legislated document that must accompany each material or object intended to come into contact with food. It should provide all information related to food contact so that anyone using the product or material knows :

• If it is suitable for its intended use.

• If the Declaration of Compliance does not specify the specific intended use, which substances should be studied in migration tests appropriate for other intended uses.

• If it is part of a final product (in the case of clearcoat), which substances it contains that should be studied in subsequent migration tests based on the intended use.

Certification (usually by a third party) certifies all products under that certification. For example, our specialized partner laboratory certifies that all products under the brand "X" are suitable for food contact according to the declared intended use in the respective Declaration of Compliance.

In Europe, all materials in contact with food (including clearcoats) must comply with Regulation 1935/04. The regulation defines several material families (including clearcoats and coatings) in its Annex I.

Our specialized partner laboratory participates in drafting the Declaration of Compliance for the product to be marketed, particularly by collaborating with companies to verify that the product is suitable for food contact, to ensure that the substances used in its manufacturing are not restricted or, if they are, do not migrate into the food in quantities exceeding the limits.
