The invention provides a dispersion of precursor titanium dioxide particles having an intensity mean peak value particle size, measured by DLS, or a number mean peak value particle size, measured by DLS, in the range from 0.2 to 2.0 μm within a dispersing medium, wherein the particle size distribution of the titanium dioxide particles in dispersion is narrower than the particle size distribution of the precursor titanium dioxide particles. There is also provided the use of the dispersion of titanium dioxide particles to attenuate infrared radiation, particularly in a cosmetic composition, more particularly a cosmetic composition to provide protection against IR radiation, more particularly IRA radiation. There is also provided a personal care composition comprising the titanium dioxide dispersion.

The present invention relates to a controlled release device for oral cavity, which is attached on a hard dental surface of a tooth. The attachment is done using any adhesive layer that can attach on enamel surface of a tooth or using a holder attached to the hard dental surface, to which holder the device can be attached, clipped or fastened. The device comprises of two or more polymeric materials forming a polymer matrix or matrices. The polymer matrices incorporate one or more agent(s), which release rate in the oral cavity can be con-trolled with the polymeric materials in the matrices. The invention also relates to a method producing a controlled re-lease device for delivering an agent to the oral cavity.

Disclosed is a cosmetic composition that contains at least one polyhydroxyalkanoate (PHA) in the form of particles having an average diameter (d50) from 0.1 nm to 50 μm. The PHA may comprise between 0.1% w/w and 30% w/w of the total cosmetic composition, and some embodiments may utilize between 1% w/w and 8% w/w. The composition may include a silicone external phase or may be in the form of a loose or packed powder. Various PHAs may be utilized, although advantageously, the PHA may have a chain length 1 and 8 carbons. In some embodiments, the PHA may be selected to have an oil absorption of between 60 to 150 grams of a desired oil per 100 grams of PHA, where the desired oil may be, e.g., sebum. Further, the composition may optionally include one or more pigments. In use, the composition may be applied to a user's skin or hair.
