John Woodruff Page 1 22/11/2012 Title: Nail varnish comprising at least one resin USP Application: USP 20080145325 Serial Code & No 11/898532 Date of filing: September 13, 2007 Inventors: Coffey-Dawe; Lizabeth-Ann; France Claimed is a nail varnish composition comprising an organic solvent, a gelling agent and at least one ketone/aldehyde resin for the non-therapeutic care of the nails and also for obtaining a glossy film after deposition on the nail. The organic solvent may be any typical of nail varnish compositions but short-chain esters comprising 3 to 8 carbon atoms are specifically mentioned. These include ethyl acetate, methyl acetate, propyl acetate, isopropyl acetate, n-butyl acetate, isopentyl acetate, methoxypropyl acetate, butyl lactate, and mixtures thereof. Ketone/aldehyde resins are the products of the polycondensation of mixtures of at least one ketone and of at least one aldehyde. Non-limiting examples of suitable ketones include acetone, acetophenone and methyl ethyl ketone of which acetophenone is preferred. At least one aldehyde used for the synthesis of the ketone/aldehyde resins is chosen from formaldehyde and mixtures of formaldehyde with other aldehydes. The ketone/aldehyde-resins may be hydrogenated in the presence of a suitable catalyst whereby the carbonyl group is converted into a hydroxyl group. They may be further modified by reacting them with isophorone diisocyanate. The composition also includes one or more film-forming polymers and a plasticiser and a suitable gelling agent such as hydrophobic silica or an organophilic clay, benzyldimethylammonium stearate being a preferred example. Suitable pigments and dyestuffs, pearling agents and other additives commonly found in nail varnish compositions are included to improve product stability and aesthetic appeal. Title: Method of applying makeup to a surface by means of a magnetic composition including reflective particles having metallic lustre USP Application: USP 20080127990 Serial Code & No 11/663975 Date of filing: July 8, 2005 Assignee: L'Oreal, Paris Described are cosmetic compositions that contain particles movable under the effect of a magnetic field. The particles are described as having non-zero magnetic susceptibility and constitute at least in part of reflective particles. These include a substrate selected from a group that includes glasses, ceramics, graphite, metal oxides, aluminas, silicas, aluminosilicates and borosilicates, synthetic mica, and mixtures thereof, coated with at least one metallic compound. The magnetic bodies may comprise any metal that is sensitive to a magnetic field but soft iron is preferred. The particles are preferably an elongate shape, so when they are subjected to the magnetic field, they tend to become oriented with their longitudinal axes in alignment with the field lines. A number of suitable materials are commercially available from Merck, BASF, and Eckart and from Engelhard and these are listed. 1 John Woodruff Page 2 22/11/2012 Not all particles cited in the patent are reflective; also described is a magnetic latex containing grains of ferrite that are evenly distributed in a polystyrene matrix. The latex contains 65% iron oxide, the mean diameter of the polystyrene particles being 890 nm, and the dry material mass content being 10%. It is also possible to use colloidal suspensions of nano particles of iron. The composition is preferably in powder form and applied by brush. The magnetic field is preferably generated by an electromagnet, which when switched on and brought to the surface where the composition has been applied; it is capable of orientating the particles into patterns. Liquid compositions are suggested for nail enamel compositions and these generally include a volatile organic solvent and a film-forming polymer. It is suggested that novel makeup effects are possible by applying the magnetic field and that it is also possible to modify the clarity of the composition and thus to model the appearance of the face in the regions exposed to the magnetic field. By way of example, the magnetic field may be applied so as to darken the sides of the face to make it appear thinner than it really is. Title: Botanical butter stick lip balm USP Application: USP 20080089916 Serial Code & No 11/904927 Date of filing: September 28, 2007 Assignee: Wyeth, NJ. Claimed is a stick lip balm that comprises at least 90% botanically derived materials and can be formed into a stick sufficiently robust to substantially retain the stick shape under normal conditions of shipping, storage and usage. The applicants claim that conventional stick lip balms formed using petroleum derived base waxes, while having protective properties, may not replenish natural lip lipids as well as naturally derived lipids and thus may not maintain natural moisture balance and prevent drying, chapping and cracking of lips. The composition described includes carnauba wax, candelilla wax, jojoba esters, botanical butters and at least one additional moisturising agent. At least three different botanical butters selected from an extensive group of these are present in the formulation. The total amount of butter is typically about 2% to about 20%.The moisturising agent is one or more botanical oils and a mixture of coconut oil with sunflower oil is preferred. The amount of beeswax, carnauba and candelilla is preferably less than 20% of the total composition with the amount of beeswax preferably less than 5% of the total composition. Conventional waxes, particularly beeswax while useful for imparting structural support, also impart a rigidity that does not favourably contribute to a rich, soft, smooth lip feel, claim the applicants. To obtain both the emollient properties and desired structure a mixture of jojoba esters is used. A mixed jojoba ester with a melting point range of 47-51° C is used in combination with a mixed jojoba ester having a melting point range of 56-61°C and the total amount of jojoba ester is about 5% to about 50% of the total composition. The claimed ranges for constituents are very wide throughout the patent. The composition also includes tocopherol as an antioxidant, a natural flavour and may contain colour and other ingredients to improve its aesthetics and stability. An example formulation is given as follows: 2 John Woodruff Page 3 22/11/2012 Amount Ingredient % wt/wt Yellow Beeswax 3.50 Shea butter 0.75 Coconut oil 10.75 Carnuauba wax 1.25 Candelilla wax 13.00 Flavouring 4 .00 Mango butter 0.75 Tocopheryl acetate 1.00 Tocopherol 0.20 Avocado butter 0.75 Jojoba esters (mpt 56-61°C) 8..00 Jojoba esters (mpt 47-51°C) 11.00 Olive butter 0.75 Raspberry butter 0.75 Sunflower seed oil 43.55 3 John Woodruff Page 4 22/11/2012 Hair straightening is a common requirement in hairdressing, which generally requires the application of thioglycollates or strong alkalies. Both methods can be irritating to the scalp and cause significant damage to the hair. The three patent abstracts that follow suggest alternative methods; the first is based on the use of adenine as the active ingredient; the second uses a sugar compound and the third method utilises urea in combination with a mixture of plant extracts. Title: Method of treating hair US Patent: 8,182,798 Appl. No. 12/598,039 Date Granted: 22-05-12 Assignee: Conopco, Inc. Claimed is a method of hair styling or straightening comprising: an active ingredient selected from adenine, guanine or derivatives thereof. In the preamble the applicants state that a problem with straightened hair is that once the straightening process has taken place hair tends to increase in volume causing it to appear fluffy, this is especially troublesome in humid conditions. The patent claims that compositions containing adenine or guanine can be used to impart humidity resistance to straightened hair and thus retain its style. The preferred active is adenine, most preferably comprising from 0.1 wt % to 5 wt % of the total composition. An organic acid is required to act as a solvent for the adenine and either tartaric or citric acid is preferred and this is present at from 1 – 10% in a ratio of 1:1 to 1:1:5 adenine to organic acid. Tests show that the ideal pH is approximately 6 so the organic acid requires partial neutralisation with triethanolamine. The patent claims that the presence of styling aids is advantageous and materials such as vinyl polymers are preferred, in particular block copolymers, preferably comprising 0.75 to 6% by weight based on total weight of the composition. However virtually all known styling polymers are mentioned as being suitable and the preferred product form is a leave-in hair conditioner. In an example formulation the conditioner contains a 50% anionic emulsion of dimethiconol and TEA-dodecylbenzenesulfonate and the conditioning aid is cetrimonium chloride with cetearyl alcohol. After application of the preferred composition the hair is straightened by the use of heat and ceramic tongs. 4 John Woodruff Page 5 22/11/2012 Decorative cosmetics are the theme for these 3 patent abstracts; two suggest improvements to non-transfer lipsticks and the third describes encapsulated fluorescent compounds. Title: Composition containing a semi-crystalline polymer and a volatile oil US Patent: 8,142,765 Application No. 10/502,447 Date Granted: March 27, 2012 Assignee: L'Oreal S.A Non-transfer lipsticks are available in the market place but users often complain of the lack of comfort and gloss of these types of product. The inventors claim to have improved the application of such products using the combinations described in the patent. Claimed is a makeup composition comprising at least one liquid fatty phase structured with at least one semi-crystalline polymer having an organic structure, a colorant and a volatile oil. The composition is in the form of a stick which on keratin materials, particularly the lips, lays down a glossy film that does not undergo transfer to objects with which the keratin materials come into contact.
