Description: PERSONAL CARE COMPOSITIONS The present invention relates to personal care compositions containing sunscreening compounds to counteract the deleterious effects of UV radiation. In one aspect of the present invention the personal care compositions are sunscreen compositions in which a sunscreening compound is used to protect the user's skin or hair from UV radiation. The term "sunscreen composition" is used herein to encompass sunscreening compositions such as moisturisers, day creams, tanning lotions and sunblockers which are intended for topical application to provide protection for the skin or hair against the sun's rays or other sources of ultraviolet (UV) radiation. Such sunscreen compositions may contain additional inorganic or organic sunscreening agents. In a further aspect of the present invention the personal care compositions are cosmetic/toiletries compositions containing a sunscreening compound to protect the compositions from the deleterious effects of exposure of the compositions to UV radiation. The term "cosmetic/toiletries composition" is used herein to encompass compositions intended for application to the skin or hair in which the sunscreen compounds are present to protect the compositions from the deleterious effects of exposure of the composition to UV radiation. Examples of cosmetic/toiletries composition include gels such as bath gels or shower gels, shampoos optionally containing conditioning agents and/or antidandruff agents, hair conditioners, liquid soaps, creams and lotions. Such compositions may be emulsions (oil-in-water emulsions or water-in-oil emulsions). Most UV absorbing molecules that are permitted for use in the cosmetics, toiletries or healthcare field are oil soluble. There are very few water soluble UV absorbing molecules and there are no high efficiency (Extinction coefficient > 15000) water soluble molecules that absorb in the UVA region between 320 nm and 400 nm. Protection of the skin from these wavelengths is essential as these wavelengths are implicated in both direct UV mediated damage and indirect free radical damage. The deleterious effects of this on the skin include premature ageing, polymorphic light eruptions, skin cancer etc. The deleterious effects of UV radiation on cosmetic/toiletries compositions include colour fading, polymer breakdown leading to product structural instability, actives (eg vitamins) being destroyed etc. One class of water soluble UV absorbing molecules has been disclosed, which are Mycosporine-like amino acids (MAAs). These compounds, which are derived from marine organisms, have been suggested for use as sunscreens. However, the present inventors have discovered that MAAs are not suitable to be the sole suncreening agent in sunscreen compositions, but do offer benefits when used in conjunction with a conventional sunscreening agent, for example those listed in Council Directive 76/768/EEC of 27 July 1976 on the approximation of the laws of the Member States relating to cosmetic products, as last amended by Commission Directive 200/41/EC of 19 June 2000. In particular, the MAA and conventional sunscreen protect each other from degradation, whilst offering improved UV protection over that achieved with a conventional sunscreening agent alone. The present invention provides personal care compositions comprising sunscreening compounds which are mycosprorine-like amino acids (MAAs) of formula I in which Ri is: (a) H; or (b) a group of formula II -CH(R 2 )CH 2 OH (II) in which R 2 is H or Me; or (c) a group of formula III -CH(R 3 )COOH (III) in which R 3 is H or a straight or branched alkyl group containing 1 to 3 carbon atoms optionally substituted by hydroxy or an ester thereof; or (d) a group of formula IV -C(R 4 )=CHMe (IV) in which R 4 is H or -COOH; and R 5 is -CH 3 or a group of formula III as defined above or an ester thereof; and an additional inorganic or organic sunscreening agent. The compounds of formula I can exist as different tautomers. The present invention embraces all such tautomers and mixtures thereof. The compounds of formula I have an asymmetric carbon atom and can therefore exist as different enantiomers. The present invention embraces all such enantiomers and mixtures thereof. Compounds of formula I in which the group of formula II or III contains a chiral centre can exist as different stereoisomers. The present invention embraces all such stereoisomers and mixtures thereof. In preferred compounds of formula I in which Ri is a group of formula III, R 3 is H, -CH 2 OH, -CH(OH)Me or -CHMe 2 . In preferred compounds of formula I in which R 5 is a group of formula III, R 3 is H or -CH 2 OH. Examples of particularly preferred compounds of formula I are=given in Table 1 below. Table 1 The mycosporine-like amino acids can be chemically synthesised or can be extracted from marine micro algae. For chemical synthesis: Compounds of formula I may be prepared by dihydroxylating a compound of formula V with osmium tetraoxide catalysis or by epoxidation with sodium hypochlorite followed by hydrolysis. Compounds of formula V may be prepared by the condensation of an amine of formula H 2 NR 1 with a carbonylcyclohexenyl compound of formula VIA or by the condensation of an amine of formula H 2 NR 5 with a carbonylcyclohexenyl compound of formula VIB Compounds of formula V may alternatively be prepared from carbonylcyclohexenyl compounds of formula VIA or VIB by reacting the compound of formula VIA or VIB with a chlorinating agent such as Vilsmeier's Reagent to give a compound of formula VILA or VIIB respectively CL which is then reacted with an amine of formula H 2 NR 1 or H 2 NR 5 respectively. Compounds of formula VIA or VIB may be prepared by reacting a compound of formula VIII Vn\ with an amine of formula NH2R 5 or NH 2 Rι respectively. The compound of formula VIII may be prepared by the methylation of a compound of formula IX ^ The compound of formula IX may be prepared from a compound of formula X X by reaction with aqueous cupric chloride. The compound of formula X may be prepared from 4-methoxybenzylchloride by a process involving the steps of silylation, Birch reduction and protodesilylation. Compounds of formula I may be prepared by similar reactions to those described above in which the 1 ,2-diol substituent is introduced at an earlier stage. It may then be necessary to protect this diol substituent during subsequent stages of the synthesis by methods which are well known to those skilled in the art. For extraction from marine micro-algae: Axenic (bacteria free) micro-algae known to be rich in compounds of formula I (e.g. the dinoflagellate Gymnodinium catenatum) are grown using aseptic techniques in sterilised medium with appropriate trace metal, metal chelating compound and vitamin addition (e.g. f/2 medium or Plymouth Erdschreiber Medium). Photosynthetically active radiation is provided by Philip's daylight fluorescent tubes at a light intensity of 80 or 100μm "2 s "1 with supplementary UVR on 12:12 or a 18:6 h light: dark cycle. Temperature is kept at 15-20°C depending on species and optimum conditions of pH and turbulence are chosen. Cells are harvested during logarithmic growth phase using centrifugation or filtration. The compounds of formula I can then be solvent extracted (e.g. cold tetrahydrofuran.methanol 20:80, v/v), concentrated and chromatographically purified from the cells to produce defined pure compounds. Alternatively cells can be digested and filtered to remove cell debris thus producing an extract containing the compound(s) The personal care compositions of the present invention may contain 0.05 to 10% of the mycosporine-like amino acid by weight of the total composition. In compositions intended to be applied to the skin or hair to protect the skin or hair from the deleterious effects of exposure to UV radiation, the amount of mycosporine-like amino acid that may be present is preferably in the range 0.5 to 10%, more preferably 1 to 6%. ln compositions in which the mycosporine-like amino acid is present to protect the compositions from the deleterious effects of exposure to UV radiation, the amount of mycosporine-like amino acid present that may be present is preferably less than 1% by weight of the total composition, more preferably 0.05 to 0.6%, most preferably 0.3 to 0.5%.
