Provided in various embodiments are compositions for topical application to the skin of a mammal, methods for their preparation, and their uses in skin care compositions to reduce adhesion of unwanted particles to the skin. When a hydrophobic non-volatile solvent and a hydrophobic non-volatile high melting point material with a melting point in the range of 60&#xb0; C. and 100&#xb0; C. are combined with a hydrophobic volatile solvent which compatibilizes the hydrophobic non-volatile solvent and the hydrophobic non-volatile high melting point material and the hydrophobic non-volatile high melting point material is selected to be at least partially incompatible with the hydrophobic non-volatile solvent in the absence of the hydrophobic volatile solvent, the resulting composition may be applied to skin to reduce adhesion of unwanted particles to the skin.

Compositions for application to the skin for reducing adhesion of pollution particles on skin and methods of preparing same

The invention relates to silicone containing compositions able to form adhesive films on substrates, which typically comprises a curable silicone composition comprising components (a), (d) and at least one of (b) or (c): a. a polyorganosiloxane resin, composed of M and Q units having at least 3 alkenyl groups per molecule, herein after called 'SiVi' groups, b. a polyorganosiloxane compound having at least 2 Si-bonded hydrogen groups on the polysiloxane chain, hereinafter called 'SiH' groups, c. a telechelic polyorganosiloxane compound having terminal Si&#x2014;H groups, and d. a hydrosilylation catalyst for the reaction of SiH groups with SiVi groups, e. a liquid diluent in an amount of from 0% to maximum 40% by weight of composition said components reacting together by hydrosilylation at a temperature below 400 C when they are brought into contact on a substrate and cure to form a continuous film on the substrate. Such formulation can cure quickly at room temperature and can provide good balance between adhesion and tack.
