Abstract
New compounds which are useful as ultraviolet absorbing agents (UVAs) may be used for improving the sun protection factor (SPF) of textile fibre material.
Description
Compounds having ultra-violet absorption properties
The present invention relates to new compounds which are useful as ultraviolet absorbing agents (UVAs) and to a method of improving the sun protection factor (SPF) of textile fibre material treated with the new compounds.
It is known that light radiation of wavelengths 280-400 nm permits tanning of the epidermis. Also known is that rays of wavelengths 280-320 nm (termed UV-B*radiation), cause erythemas and skin burning which can inhibit skin tanning.
Radiation of wavelengths 320-400 nm (termed UV-A radiation) is known to induce skin tanning but can also cause skin damage, especially to sensitive skin which is exposed to sunlight for long periods. Examples of such damage include loss of skin elasticity and the appearance of wrinkles, promotion of the onset of erythemal reaction and the inducement of photo toxic or photoallergic reactions.
Any effective protection of the skin from the damaging effects of undue exposure to sunlight clearly needs to include means for absorbing both UV-A and UV-B components of sunlight before they reach the skin surface.
Traditionally, protection of exposed human skin against potential damage by the UV components in sunlight has been effected by directly applying to the skin a preparation containing a UV absorber. In areas of the world, e.g. Australia and America, which enjoy especially sunny climates, there has been a great increase in the awareness of the potential hazards of undue exposure to sunlight, compounded by fears of the consequences of alleged damage to the ozone layer. Some of the more distressing embodiments of skin damage caused by excessive, unprotected exposure to sunlight are development of melanomas or carcinomas on the skin.
One aspect of the desire to increase rhe level of skin protection against sunlight has been the consideration of additional measures, over and above the direct protection of the skin.
For example, consideration has been given to the provision of protection to skin covered by clothing and thus not directly exposed to sunlight.
Most natural and synthetic textile materials are at least partially permeable to UV components of sunlight. Accordingly, the mere wearing of clothing does not necessarily provide skin beneath the clothing with adequate protection against damage by UV radiation. Although clothing containing a deeply coloured dye and/or having a tight weave texture may provide a reasonable level of protection to skin beneath it, such clothing is not practical in hot sunny climates, from the standpoint of the personal comfort of the wearer.
There is a need, therefore, to provide protection against UV radiation for skin which lies underneath clothing, including lightweight summer clothing, which is undyed or dyed only in pale shades. Depending on the nature of the dyestuff, even skin beneath clothing dyed in some dark shades may also require protection from UV radiation.
Such lightweight summer clothing normally has a density. of of less than 200 g/m2 and has a sun protection factor rating between 1.5 and 20, depending on the type of fibre from which the clothing is manufactured.
The SPF rating of a sun protectant (sun cream or clothing) may be defined as the multiple of the time taken for the average person wearing the sun protectant to suffer sun burning under average exposure to sun. For example, if an average person would normally suffer sun burn after 30 minutes under standard exposure conditions, a sun protectant having an
SPF rating of 5 would extend the period of protection from 30 minutes to 2 hours and 30 minutes. For people living in especially sunny climates, where mean sun burn times are minimal, e.g. only 15 minutes for an average fair-skinned person at the hottest time of the day, SPF ratings of at least 20 are desired for lightweight clothing.
It is already known, e.g. from WO 94/4515, that the application of specified types of UVA to a light-weighr textile materials in general can effect an increase in the SPF value of the textile so treated. The increase in SPF value achieved thereby, however, is relatively modest.
Certain new compounds have now been found which can be readily produced and which, unexpectedly, impart greatly increased SPF ratings to textile fibre materials treated with the new compounds.
Accordingly, the present invention provides a compound having the formula:
in which m is 1 or 2; A is a residue selected from those having the formulae:
in which R is phenyl, optionally substituted by 1 or 2 C1-C4alkyl groups, preferably tolyl or xylyl, or by I or 2 C1-C18alkoxy groups, or R is a group having the formula:
X is F, Cl or NHCH2OH and X1 is F, Cl. NHCH20H or a group having the formula:
-8 CO2-C1-C4aIkyI -B B --C(=O)-C,-C4alkyl
B is -O-, -NH- or -SO2-, and D is a group having one of the formulae::
CH2-C(=O) -NH( CH2OH), CH2-C(=O)-N(CH2OH)2 or -CH2CH2-OS03M in which M is hydrogen, sodium, potassium, calcium, magnesium, ammonium, mono-, di-, tri- or tetra-Cl-C4alkylammonium or ammonium that is di- or tn-substituted by a mixture of C1-C4alkyl and C1-C4hydroxyalkyl groups, preferably sodium, or, when A is a residue of formula (5) or (6), D may also be a group of formula:
B 3CO2-Cr-C4alkyl
in which B and M have their previous significance and n is 0 or 1, provided that at least one S03M group is present, or the formula:
in which X, X1 and M have their previous significance; provided that the following compounds are excluded: a) those in which A is a residue of formula (2), (3) or (4), B is -0- and D is a group of formula
CH2-C(=O)-NH(CH20H) or CH2-C(=O)-N(CH2OH)2; b) the compound 4-glycidyloxy-2-hydroxy benzophenone; and c) the compound 2-(2-hydroxy-4-glycidyloxy)-4,6-(2,4-dimethylphenyl)-1,3,5-triazine.
Preferred compounds of formula (1) include those having one of the formulae:
in which R has its previous significance and D1 is a group having the formula
CN2-C(=O)-NN(CH2OH) or CH2-C(=O)-N(CH2OH)2;
in which D1 has its previous significance;
in which D1 has its previous significance; ;
SO3M (io > B NYN xlNJJ\ N B CQ.C1-C4a!kyl SO3M (11) B or NN or X1 N)\ B -- CO-C1 -C4aIkyI SO2CH2CH2OSO3M B (12) NN X l N C02-C l-C,alkyl in which X is F or Cl and B and M have their previous significance and in which preferably X is C1, B is NH and M is Na;
in which n has its previous significance, provided that at least one group -SO3M is present,
X is F or C1 and X1 is F, C1 or a group having one of the formulae::
B 9 CO2-CI-C4alkyl C(=O).C1 -C4aikyI
in which B and M have their previous significance;
in which each X is the same and is F or C1 and each X1 is the same and is F, Cl or a group having one of the formulae:
Q < 3 CO2-Cl-C4alkyl C(=Q)-C1 -C4aIkyI
in which B and M have their previous significance, or
in which M has its previous significance but is preferably Na.
The compounds of formula (1) may be produced by reacting, under known reaction conditions, a compound of formula A-(BH)m in which A, B and m have their previous significance, with m moles of a compound L-D, in which D has its previous significance and L is a leaving group or atom, preferably a halogen atom, especially a chlorine atom.
The starting materials A-(BH)m and L-D are known compounds which are readily available.
The present invention also provides a method for the treatment of a textile fibre material, comprising treating the textile fibre material with 0.05 to 3.0% by weight, based on the weight of the textile fibre material, of one or more compounds having the formula (1).
The textile fibres treated according to the method of the present invention may be natural or synthetic fibres or mixtures thereof. Examples of natural fibres include vegetable fibres such as cotton, viscose, flax, rayon or linen, preferably cotton and animal fibres such as wool, mohair, cashmere, angora and silk, preferably wool. Synthetic fibres include polyester, polyamide and polyacrylonitrile fibres.
Preferably, textile fibres treated according to the method of the present invention have a density of less than 200 g/m2 and have not been previously dyed in deep shades.
Some of the compounds of formula (1) used in the method of the present invention may be only sparingly soluble in water and may need to be applied in dispersed form. For this purpose, they may be milled with an appropriate dispersant, conveniently using quartz balls and an impeller, down to a particle size of 1-2 microns.
As dispersing agents for such sparingly-soluble compounds of formula (1) there may be mentioned: - acid esters or their salts of alkylene oxide adducts, e.g., acid esters or their salts of a
polyadduct of 4 to 40 moles of ethylene oxide with 1 mole of a phenol, or phosphoric
acid esters of the adduct of 6 to 30 moles of ethylene oxide with 1 mole of
4-nonylphenol, 1 mole of dinonylphenol or, especially, with 1 mole of compounds
which have been produced by the addition of 1 to 3 moles of styrenes on to 1 mole of
phenol; - polystyrene sulphonates; - fatty acid taurides; - alkylated diphenyloxide-mono- or -di-sulphonates; - sulphonates of polycarboxylic acid esters;; - addition products of 1 to 60, preferably 2 to 30 moles of ethylene oxide and/or
propylene oxide on to fatty amines, fatty amides, fatty acids or fatty alcohols, each
having 8 to 22 carbon atoms, or on to tri- to hexavalent C3-C6alkanols,
the addition products having been converted into an acid ester with an organic
dicarboxylic acid or with an inorganic polybasic acid; - lignin sulphonates; and, in particular formaldehyde condensation products, e.g., condensation products of lignin sulphonates
and/or phenol and formaldehyde; condensation products of formaldehyde with
aromatic sulphonic acids, e.g., condensation products of ditolylethersuiphonates and
formaldehyde; condensation products of naphthalenesulphonic acid and/or naphthol- or
naphthylaminesulphonic acids and formaldehyde; condensation products of
phenolsulphonic acids and/or sulphonated dihydroxydiphenylsulphone and
phenols or cresols with formaldehyde and/or urea; or condensation
products of diphenyloxide-disulphonic acid derivatives with formaldehyde.
Depending on the type of compound of formula (1) used, it may be beneficial toNc'arIy out the treatment in a neutral, alkaline or acidic bath. The method is usually conducted in the temperature range of from 20 to 140"C.,for example at or near to the boiling point of the aqueous bath, e.g. at about 90"C.
Solutions of the compound of formula (1), or its emulsions inorganic solvents may also be used in the method of the present invention. For example, the so-called solvent dyeing (pad thermofix application) or exhaust dyeing methods in dyeing machines may be used.
If the method of the present invention is combined with a textile treatment or finishing method, such combined treatment may be advantageously carried out using appropriate stable preparations which contain the compound of formula (1) in a concentration such that the desired SPF improvement is achieved.
In certain cases, the compound of formula (1) is made fully effective by an after-treatment. This may comprise a chemical treatment such as treatment with an acid, a thermal treatment or a combined thermal/chemical treatment.
It is often advantageous to use the compound of formula (1) in admixture with an assistant or extender such as anhydrous sodium sulfate, sodium sulfate decahydrate, sodium chloride, sodium carbonate, an alkali metal phosphate such as sodium or potassium orthophosphate, sodium or potassium pyrophosphate or sodium or potassium tripolyphosphate, or an alkali metal silicate such as sodium silicate.
In addition to the compounds of formula (1), a minor proportion of one or more adjuvants may also be employed in the method of the present invention. Examples of adjuvants include emulsifiers, perfumes, colouring dyes, opacifiers, optical whitening agents, bactericides, nonionic surfactants, fabric care ingredients, especially fabric softeners, stain release or stain repellant ingredients or water-proofing agents, anti-gelling agents such as nitrites or nitrates of alkali metals, especially sodium nitrate, and corrosion inhibitors such as sodium silicate.
The amount of each of these optional adjuvants should not exceed 1% by weight on the treated fibre.
The method of the present invention, in addition to providing protection tQ the skin, also increases the useful life of a textile article treated according to the present invention. In particular, the tear resistance and/or lightfastness of the treated textile fibre material may be improved.
Accordingly, the present invention still further provides a method of increasing the SPF rating of textile fibre material, comprising treating the textile fibre material with 0.05 to 3.0% by weight, based on the weight of the textile fibre material, of one or more compounds having the formula (1).
The present invention also provides a textile fabric produced from a fibre treated according to the method of the present invention as well as an article of clothing produced from the said fabric.
Such textile fabrics and articles of clothing produced from the said fabrics typically have an SPF rating of 20 and above whereas untreated cotton, for example, generally has an
SPF rating of from 2 to 4.
The following Examples further illustrate the present invention.
