Using Waterproof Titanium Dioxide in Tone-Up Products

Yes, the Waterproof types of Titanium Dioxide (250nm, 300nm, 400nm) are suitable for use in tone-up lotions and shower creams. These types are specially treated to adhere well to the skin and provide a waterproof effect, which helps the tone-up result last longer, even after rinsing in shower products.

Mixing Method

Simply shaking the powder into an existing lotion or shower cream base is not sufficient. Titanium Dioxide powder needs to be properly dispersed to avoid clumps and ensure an even tone-up effect. For best results, you will need to use a high-shear mixer or a blender to thoroughly blend the powder into the base until it is completely uniform. Adding the powder directly to a finished product and just shaking will likely result in poor dispersion and an uneven appearance.

Ideally, for a stable and well-dispersed product, the Titanium Dioxide should be incorporated during the formulation process, often by dispersing it in an oil phase or using suitable dispersing agents before adding it to the main base.

Skin Adherence

The Waterproof types of Titanium Dioxide, such as Titanium Dioxide 250nm WaterProof™ (Dimethicone Treated) and Titanium Dioxide 300nm WaterProof™ (Triethoxycaprylylsilane Treated), are specifically designed for good adherence to the skin and waterproof properties. This makes them effective for long-lasting tone-up effects, including in rinse-off products like shower creams.

Additional Ingredients

While you can add these Titanium Dioxide powders to a base, achieving a stable and aesthetically pleasing tone-up product often requires more than just the powder and the base. Depending on the specific base formulation, you might need dispersing agents to help the powder mix evenly and stay suspended without settling over time. However, if you are simply adding it to a finished product for personal use, the primary challenge will be achieving proper dispersion, which requires adequate mixing equipment.

For tone-up lotion/cream, Titanium Dioxide 250nm WaterProof™ and Titanium Dioxide 300nm WaterProof™ are good options. Titanium Dioxide 400nm WaterProof™ (Super Coverage) is also waterproof and offers high coverage, often used in makeup powders, but can potentially be used in creams for a stronger effect, provided it is properly dispersed.
