Abstract
A two-phase oral care whitening composition including a hydrophobic phase and a hydrophilic phase, and methods for oral care whitening teeth with the same are provided. The hydrophobic phase may include a source of hydrogen peroxide and an acyl donor. The hydrophilic phase may include an enzyme that catalyzes the generation of peracetic acid between the source of hydrogen peroxide and the acyl donor. At least one of the hydrophobic phase and the hydrophilic phase may further include at least one surfactant.
Claims16
A two-phase oral care whitening composition, comprising:
- a hydrophobic phase comprising a source of hydrogen peroxide;
- a nonionic surfactant;
- and an acyl donor;
- and
- a hydrophilic phase comprising an amphoteric surfactant;
- an enzyme that catalyzes the generation of peracetic acid between the source of hydrogen peroxide and the acyl donor, and
- wherein when the hydrophobic phase and the hydrophilic phase are combined the resulting oral care product has a viscosity of from about 75,000 cP to about 200,000 cP.
