Definitions

  • the present invention consists in a sunscreen composition including one or more insect repellents and one or more UV sunscreening agents characterised in that the composition includes 3-9% by weight in total of at least two emulsifiers, based on the total weight of the composition.
  • the sunscreen agent in combination with insect repellent give a composition that is stable and effective with respect to SPF.
  • One or more inorganic compounds are incorporated in the composition of the invention as a sunscreening agent.
  • the preferred inorganic compounds are titanium oxide and zinc oxide.
  • the particle size can be selected to scatter light in the UV range whilst transmitting light in the visible range thereby remaining transparent on the skin. This is highly desirable from a cosmetic point of view.
  • Suitable repellents include N,N-diethyl-m-toluamide (DEET), dipropyl pyridine-2,5- dicarboxylate, pyrethrins, dimethyl phthalate, 2,3:4,5-bis(2-butylene)tetrahydrofurfural, citronella, geraniol, lemon grass oil, eugenol, p-menthane-3,8-diol, ethylbutyl acetylamino propionate, 1-piperidinecarboxylic acid and 2-(2-hydroxyethyl)- ester 1 -methylpropyl-ester.
  • DEET N,N-diethyl-m-toluamide
  • DEET dipropyl pyridine-2,5- dicarboxylate
  • pyrethrins dimethyl phthalate
  • 2,3:4,5-bis(2-butylene)tetrahydrofurfural citronella
  • geraniol lemon grass
  • the total amount of insect repellent in the composition may be 4-20% by weight based on the total weight of the composition, preferably 4-15% by weight and more preferably 5-10% by weight.
  • the composition may include one or more other UV sunscreening agents. These are generally organic compounds which absorb a specific range of UV radiation. Suitable sunscreening agents include octyl methoxycinnamate, oxybenzone, amino benzoic acid, Cinoxate, DEA-methoxycinnamate, Digalloyl, Dioxybenzene, Padimate O, Ethyl dihydroxypropyl p-aminobenzoate, octyl salicylate, glyceryl aminobenzoate, Homosalate, Urocanic acid, isopropylbenzyl salicylate, menthyl anthranilate, octocrylene, Sulisbenzone and its sodium salt and triethanolamine salicylate.
  • sunscreening agents include octyl methoxycinnamate, oxybenzone, amino benzoic acid, Cinoxate, DEA-methoxycinnamate, Digalloyl, Dioxybenzene, Padimate O, Ethy
  • a combination of octylmethoxycinnamate and oxybenzone is most preferred.
  • Each sunscreening agent is preferably incorporated in the composition in an amount of 3-10% by weight based on the total weight of the composition.
  • Dispersions may be formed temporarily through agitation of the two immiscible liquids, however, resolution of the emulsion is usually rapid and complete unless a stabilising additive or emulsifier is used.
  • Emulsions usually consist of water or an aqueous solution as one immiscible phase and some organic liquid, or "oil", as the other phase.
  • oil When the oil is dispersed in the aqueous phase the emulsion is called oil in water (o/w ) or alternatively, if the aqueous phase is dispersed in the oily phase the emulsion is described as water in oil ( w/o ).
  • An emulsifying agent is usually required to stabilise the emulsion.
  • Such agents are ordinarily large molecules of which the greatest part of the molecule is non-polar (for solubility in the oil phase ) and a smaller part is polar ( for orientation and solubility into the water phase ).
  • compositions of the invention are preferably in the form of an oil in water emulsion.
  • An example of a suitable emulsifying system includes fatty acid ethoxylates such as glycerol monostearate, fatty alcohol ethoxylates such as ethoxy (20 ) stearyl alcohol, fatty alcohols such as C ⁇ 6 - ⁇ 8 fatty alcohols, and blends of fatty alcohol ethoxylates with alkyl phenol ethoxylates such as a blend of cetostearyl alcohol and PEG stearate. A wide range of other emulsifiers also appear useful for this purpose.
  • the composition optionally includes a film former. The preferred film former is
  • the composition may include thickeners, chelating agents and pH adjusting agents as required. These are readily known to the person skilled in the art. Suitable thickeners include acidic acrylates such as carboxyl polymethylene, and cellulose based thickeners such as methyl cellulose, guar gum, sodium alginate and sodium carboxymethyl cellulose. A suitable chelating agent is disodium EDTA. Triethanolamine may be used as a neutraliser as if required.
  • the inventors have found that in preparing an emulsion, the order of addition of ingredients affects the SPF of the final composition.
  • a third aspect of the invention consists in a method of manufacturing a sunscreen composition including one or more insect repellents and one or more UV sunscreening agents, the composition being in the form of an emulsion having a water phase and an oil phase characterised in that the water phase and oil phase are prepared and combined to form an emulsion prior to the addition of at least one inorganic compound which is used as a sunscreening agent.
  • the invention consists in a method of manufacturing a sunscreen composition including the steps of:
  • the invention consists in a sunscreening composition manufactured according to the methods described above. The invention will now be further described with reference to a number of examples.
  • a zinc oxide inorganic sunscreen agent is used, a different thickening system would be appropriate.
  • a cellulose-based thickener such as methyl cellulose, guar gum, sodium alginate and sodium carboxymethyl cellulose could be used, in which case a neutraliser would not be required.
  • Formulae 1 and 3 were tested in two ways: A. Determination of sun protection factor (SPF) and B. Broad spectrum test.
  • SPF sun protection factor
  • B Broad spectrum test.
  • the individual sun protection factor, SPF, of a sunscreen product is determined from the minimum erthemal dose (MED) of the skin that has been protected with the sunscreen product and from the MED of an adjacent area of unprotected skin, under specific conditions by means of the following relationship, where the UV source has constant intensity:
  • the MED is determined more precisely by a set of exposures which span a dose range of approximately 0.6 to 1.5 of the MED.
  • these doses are administered the day before the product is tested but they may be administered at the same time.
  • the result when read not only provides the denominator for calculating the protection factor but, when multiplied by the expected or likely value of the product's protection factor, provides an estimate for the longer exposure needed to assess the product.
  • the product is assessed by exposing a set of small subsite areas adjacent to the untreated areas, after application of the product. Times of exposure are selected to bracket the above estimate, when read 16h to 24h later, the MED for the treated skin is divided by the MED for untreated skin to give the protection factor.
  • compositions of formulae 1 and 3 did not transmit more than 10% of UV radiation at any wavelength between 320 nm and 360 nm inclusive.
