There is no common definition of, or test method for, nanomaterials. Croda’s Solaveils are designed with a range of particle sizes, whether they are described as nanoparticles or not depends on the country/region, the definition that is used and the test method that is applied. An indication of the relative sizes of the particles in our Solaveil ranges is indicated within this tool on the range pages. The SEM images on the range pages are also provided for you to visualise the particle structure and shapes, however they are not our recommended way of accurately measuring particle size. If you need more detailed information, or a statement about the nanomaterial status of any of our Solaveils, please contact your sales representative.
It should be noted that there are major differences in oil absorbency seen between different TiO2 powders in the Solaveil range. Oil absorbency correlates primarily with particle size: the greater the particle size, the lower the oil absorption. However, the coating also plays a role. Therefore, some TiO2 powders will require more oil to be wetted than others. You can quickly test the oil absorbance and amount of oil required for wetting by combining the desired oil dropwise, with a known quantity of metal oxide powder. More information can be found about oil absorbency in our Working with Powders Emollient Compatibility presentation which you can access here and this article here.
You can watch one of our formulators using a Solaveil dispersion to make a sun care emulsion in the video here.
The O/W emulsion format can provide a lighter sensory and tends to be less whitening than W/O systems, which is usually preferred by the consumer. Alternatively, W/O systems can offer higher efficacy and water resistance but typically have a heavier sensory. The emulsifier system selected can have a significant impact on both sensory and efficacy. It should be noted that cationic and anionic emulsifiers can be difficult to formulate with inorganic dispersions, and non-ionic or, as a minimum, combined ionic and non-ionic systems are recommended.
