SUMMARY:
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 are required to 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”.
