Japan – Proposed Amendment to Acts Regulating Harmful Substances in Household Products

Vol. 812 | January 27, 2015

The Japan Ministry of Health, Labour and Welfare (MHLW) recently proposed to amend the existing “Act on Control of Household Products Containing Harmful Substances” and “the Ordinance for Enforcement of the Act on Control of Household Products Containing Harmful Substances."

MHLW has proposed to (I) designate azo compounds as harmful substances, (II) stipulate the scope of household products containing the azo compounds, and (III) determine the criteria and test methods. Also, MHLW proposes to (IV) revise the test methods for household products containing triphenyltin compounds, tributyltin compounds and (V) formaldehyde. Following are highlights of the proposed Act and Ordinance:

    I) MHLW designates the following 24 aromatic amines as “harmful substances”:

    1. 4-aminoazobenzene
    2. 2-amino-4-nitrotoluene
    3. 4-aminobiphenyl
    4. 4,4’-oxydianiline
    5. o-anisidine
    6. o-aminoazotoluene
    7. o-toluidine
    8. 2,4- xylidine
    9. 2,6-xylidine
    10. 4-chloro-o-toluidine
    11. 2,4-diaminoanisole
    12. 4,4’-diaminodiphenylmethane
    13. 3,3’-dichlorobenzidine
    14. 3,3’-dimethyl-4,4’-diaminodiphenylmethane
    15. 3,3’-dimethylbenzidine
    16. 3,3’-dimethoxybenzidine
    17. 4,4’-thiodianiline
    18. 2,4,5-Trimethylaniline
    19. 2,4-toluylendiamine
    20. 2-naphtylamine
    21. p-cresidine
    22. p-chloroaniline
    23. benzidine
    24. 4,4’-methylene-bis-(2-chloro-aniline)

    II) The scope of “household products containing the azo compounds” that are subject to the regulation will be stipulated as follows:

    • Textile products with azo dyes: diapers, diaper covers, underwear, sleepwear, gloves, socks, intermediate garments, outer garments, caps, hats, bedding, floor coverings, tablecloths, collar ornaments, handkerchiefs, and towels, bath mats and related products
    • Leather and/or fur products with azo dyes: undergarments, gloves, intermediate garments, outer garments, caps, hats and floor coverings

    III) The criteria and test methods for the household products containing the azo compounds will be stipulated as follows:

      Any of the specified 24 aromatic amines must be less than 30mg/kg when tested with a gas chromatograph mass spectrometer.

The test method for the household products containing triphenyltin compounds and tributyltin compounds will be revised as follows:

      The test method using a gas chromatograph mass spectrometer will be used instead of flameless atomic absorption spectrometry and two-dimensional thin layer chromatography.

    IV) The test method for the household products containing formaldehyde will be revised as follows:

      In some operations, the test method for acetic acid and aqueous solution of ammonium acetate will be used instead of those using purified water.

Proposed date of adoption : March 2015
Proposed date of entry into force : April 1, 2016
