NEW ZEALAND LAW

The New Zealand Governments Environmental Risk Management Authority known as the Environmental Protection Authority [EPA] has established clear rules around teeth whiteners containing hydrogen peroxide and their use (EPA July 2011)

TEETH WHITENING PRACTITIONERS

Non Dentist Cosmetic Teeth Whitening Practitioners may USE products containing up to 12 percent hydrogen peroxide for in-chair treatments

Products containing more than 12 percent hydrogen peroxide can be used by a Registered Dentist or a person under the supervision of a Dentist

OTC Teeth Whitening Products


New Zealand Law also includes specific requirements for labelling of over-the-counter OTC tooth whitening products such as you would find in a Chemist, Supermarket, Beauty Salon, Spa, Gym,
and the like, OR Sold in the Internet

'Over the counter' [OTC] Teeth whitening products must contain less than 7 percent hydrogen peroxide [HP] or Cabamide Peroxide (CP) equivalent being 19.355%* CP

*The HP to CP formula conversion is; 1% hydrogen peroxide is equivalent to 2.765% carbamide peroxide:
1% H2O2 = 2.765% carbamide peroxide or % carbamide peroxide = % H2O2 x 2.765 and the reverse:
1% carbamide peroxide = 0.361% H2O2 or % H2O2 = % carbamide peroxide /2.765

PLUS - Such OTC products must also comply with these Labelling rules

Clause 3.4 Accordingly, in order to manage the risks of tooth-whitening products sold to the general public, OTC tooth-whitening products containing or releasing less than 7% hydrogen peroxide must have on the label, information that is equivalent to the following precautionary statements:

"If irritation develops, discontinue use. If irritation continues, consult a dentist‟;
"Use for longer than 14 days is not recommended except under the supervision of a dentist‟;
"Not recommended for use on children under 16 years of age‟;
"Avoid swallowing‟; and
"Avoid direct contact of the product with gums or eyes‟.


In New Zealand, the NZ Governments Environmental Protection Authority (EPA) (formerly ERMA) has established these Public Safety Standards for the Cosmetic Teeth Whitening products suppliers and practitioners of our industry
