EN71-7 Standard testing of pigments for finger painting
EN71-7 or EN71Part 7 is part of the European toy testing standards. It is a testing standard specifically for pigments used in finger painting.
The main test items for EN 71 Part 7 finger paints are:
(a)Colorants Colorants
(b)Preservatives
(c)Binding agents, extenders, humectants and surfactants, ingredient review Binding agents, extenders, humectants and surfactants, ingredient review
(d)Limits for the of Transfer certain elements
(e)Limits for primary aromatic amines
(f)Ethanol ethanol
(g)pH value acid-base
(h)Product information & Container Product information and packaging container
The safety standard EN 71-7 for finger paint toys will be revised from time to time. Usually the revised standard will be consistent with the presumption of compliance of the Toy Safety Directive 2009/48/EC .
In April 2014 , CEN published the revised toy safety standard EN 71-7:2014 , which puts forward requirements for finger paints. The standard also applies to finger paints in powder form (e.g., to which water is added before use).
This time EN71-7:2014 has been modified mainly in the following aspects:
1. Some new limits and test methods for impurities are proposed: 1. Finger paints containing chlorine -
containing colorants or colorants produced in chlorinated solvents: polychlorinated biphenyls: 2 mg/kg , hexachlorine Benzene: 5 mg/kg . 2. Finger paints containing carbon black: benzo (a) pyrene: 0.05 mg/kg
3. The bitter agent sucrose octaacetate was deleted, and the bitter agents benzyl ammonium benzoate and naringin were retained.
4. The following modifications have been made to the preservative requirements: benzyl alcohol benzyl alcohol is removed from the list of allowed preservatives.
5. The following preservatives are allowed, but the corresponding limits cannot be exceeded: zinc pyrithione: 0.5% ; chlorobutanol : 0.5% ; methylisothiazolinone: 0.01% ; glutaraldehyde: 0.1% . 6. Maximum concentration limits for mixtures of 5- chloro -2- methyl -1- isothiazolin -3- one and 2- methyl -1- isothiazolin -3- one containing magnesium chloride and magnesium nitrate Reduced from 0.0015% to 0.0008% ( the mixing ratio of 5- chloro -2 - methyl - 1-isothiazolin -3- one and 2- methyl -1- isothiazolin- 3- one is 3:1 ). 7. Limits and limits of nitrosamines and nitrosamine compounds in finger paints
EN71-12 : The same requirements in 2013 , that is, the content of all nitrosamines cannot exceed 0.02mg/kg , and the content of all nitrosamine compounds cannot exceed 1mg/kg .
8. Under certain acidic conditions, if finger paint contains nitrosamine compounds (for example: secondary amines) and nitrosating reagents (for example: nitrite), nitrosamines can be formed. For example, if diethanolamine (DEA, a secondary amine ) or triethanolamine that can produce DEA is combined with an auxiliary that can provide a nitrite group (such as bronopol), diethanolnitrosamine can be produced.
9. Increased purity requirements for many colorants widely used in finger paints.
10. EN71-3: 2013 replaces the migration requirements for specific elements in the original standard.
11. Finger paint will no longer be classified as a hazardous mixture, but will be classified from 3.1 according to the relevant requirements of European Union (EC) No. 1272/2008 " Regulation on Classification, Labeling and Packaging of Substances and Mixtures ( CLP ) " to a hazard level of 3.10 .
12. Taking into account the use of calcium carbonate in finger paints and the use of non-distilled water to dilute finger paints, expand the allowable pH value to 4.0 to 10.0 .
13. Containers of finger paints must not imitate food. The requirements are stricter than the EU Food Imitation Directive 87/357/EEC .
14. Labeling – Powdered finger paints require the following additional warning: “ Warning, please mix with water according to instructions before giving to children. ”
