Definitions
- the present invention relates to powder cosmetic compositions.
- it relates to powder cosmetic compositions for purposes of make-up and the like which provide improved adhesion to the skin, increased wear, coverage and reduced rub-off.
- Make-up compositions are generally available in the form of liquid or cream suspensions, emulsions, gels, anhydrous oil and wax compositions or pressed and loose powders.
- Make-up is normally applied to the face in two stages. In a first stage, a liquid or cream foundation is applied. This is followed by application of a powder composition, the function of which is to impart a smooth finish to facial skin, masking minor visible imperfections and shine.
- W088/00039 discloses a pressed facial cosmetic powder comprising a blend of moisturising and oil absorbing clays, filler, dry binder and liquid binder.
- US Patent No. 4,804,532 recites a facial cosmetic powder which utilises crystalline silica in much lower concentration than that employed in the then prior art compositions.
- This powder used as a blush or a facial coating, is said to be effective in hiding skin wrinkles, lines and pores.
- the composition is a mixture of a colour phase and a diluent phase.
- the colour phase is formed by blending crystalline silica with colourants.
- the resultant colour phase is mixed with the diluent phase, essentially formed from nacreous materials such as talc and mica, to form the composition.
- Pressed and loose cosmetic powder compositions for application to the face are well-known and help to provide good skin coverage and appearance with reduced shine, especially when used with foundations. It would however be desirable to improve the substantivity characteristics such as improved skin adhesion, wear and coverage of cosmetic powder compositions. It would also be desirable to provide a powder composition having prolonged topical anti-acne and/or anti-bacterial activity.
- a powder composition having prolonged topical anti-acne and/or anti-bacterial activity There are many compounds which are known to exhibit anti-acne and/or anti ⁇ bacterial properties when applied topically to the skin.
- a commonly used keratolytic agent having anti-acne activity is salicylic acid. Zinc oxide is also known for use in anti-acne compositions.

It is an ultralight free-flowing white powder and the particles are capable of absorbing high levels of lipophilic liquids and some hydrophilic liquids while at the same time maintaining a free-flowing powder character.
- the powder structure consists of a lattice of unit particles less than one micron that are fused into agglomerates of 20 to 100 microns and the agglomerates are loosely clustered into macro-particles or aggregates of about 200 to about 1200 micron size.
- the polymer powder is capable of containing as much as four times its weight of fluids, emulsions, dispersions or melted solids.
- Adso ⁇ tion of actives onto the polymer powder can be accomplished using a stainless steel mixing bowl and a spoon, wherein the active is added to the powder and the spoon is used to gently fold the active into the polymer powder.

- powder cosmetic compositions of the above examples provide improved skin adhesion, wear, coverage and reduced rub-off characteristics.
- compositions can be prepared as follows. The dry ingredients are weighed into a ribbon blender and mixed for about 15 minutes until homogeneous. Next the dry mixture is pulverised through an 020 herringbone screen. The liquid ingredients are then sprayed into the dry mixture with stirring. The batch is pulverised and sieved before being ready for packaging.
