Description

Sunscreen compositions with heavily reduced textile staining as a result of Bis-Ethylhexyloxyphenol Methoxyphenyl Tnazine

The present invention relates to a cosmetic preparation comprising 2,4-bis-{[4-(2-ethy!hexyioxy)-2--hydroxy]phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INC!: Bis-Ethylhexyloxyphenol Methoxyphenyl Tnazine) and at least two additives selected from the group of compounds cellulose gum, iminodisuccinate, 1-hydroxy-4-methyl-6-(2,4,4-trimethylpenfyi)-2(1H)-pyridone (piroctone) and diethylenetriaminepenta (methylenephosphonic acid)/ DTPMP.

The trend away from gented pallor towards “healthy, sporty brown skin” has been unbroken for years. In order to achieve this, people subject their skin to solar radiation since this causes pigment formation in the sense of melanin formation. However, the ultraviolet radiation of sunlight also has a harmful effect on the skin. Besides the acute damage (sunburn), long-term damage such as an increased risk of suffering from skin cancer, arises with excessive irradiation with light from the UVB region (wavelength: 280-320 nm). Moreover, the effect of too much UVB and UVA radiation (wavelength: 320-400 nm) is a weakening of the elastic and collagenous fibres of connective tissue. This leads to numerous phototoxic and photoallergic reactions, resulting in premature skin ageing.

To protect the skin, a series of light protection filter substances has therefore been developed which can be used in cosmetic preparations. These UVA and UVB filters are summarized in most industrialized countries in the form of positive lists such as Annex 7 of the German Cosmetics Ordinance.

However, the multitude of commercially available sunscreen compositions must not hide the fact that these preparations of the prior art have a series of disadvantages.

Cosmetic preparations such as sunscreen preparations that are applied to the skin regularly come into contact (intentionally or unintentionally) with items of clothing and laundry articles (e.g. hand towels), where they partly remain stuck (e.g. as “rub-off” or because fhey are “absorbed” by the fibre materials). This leads, depending on the nature of the ingredients, to stains and discolorations particularly on light-coloured textiles. These discolorations are caused in particular by non-water-soluble UVA and broadband filters such as 2,4-bis-{[4- (2-ethylhexyioxy)-2-hydroxy]phenyi}-6-(4-methoxyphenyi)-1,3,5-triazine (INC!: Bis-Ethylhexyloxypheno! Methoxyphenyl Triazine). The stains are difficult to remove by washing with conventional detergents and even become more marked during the washing process as a result of interactions with ions in the washwater.

Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.

It is an the object of the preferred embodiments of the present invention to develop a cosmetic preparation (in particular a sunscreen composition) comprising non-water-soluble broadband filters such as Bis-Ethylhexyloxyphenoi Methoxyphenyl Triazine which can be washed out of the textiles contaminated with the preparation more easily.

Comparative experiment

The experiment below was able to demonstrate the effect according to the invention by way of example: 0.5% of the auxiliary according to the invention cellulose gum were added to a Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine-confainlng formulation and the stain-reducing effect (reduction db) was determined compared to a formulation without the auxiliary according to the invention by means of an in vitro washing method. Subsequently, the synergistic effect of two and three combinations was confirmed by addition of the further auxiliaries according to the invention.

As proof of the improved ability to be washed out and reduced staining of the preparations according to the invention, in vitro experiments were carried out, the results of which are shown in Table 1.

Various sunscreen emulsions were tested as regards the formation of yellow stains via an in vitro appiication/wash cycle. For this, white prewashed cotton monitors (100% cotton) were used. For this, in each case 50 mg of the test formulation were spread evenly on PMMA Schonberg plates (5.0 χ 5.0 cm) and transferred directly to the test textile using pressure. Then, the stained cotton samples were stored in the air for 12 h under laboratory conditions.

After drying, a colorimetric characterization of the resulting initial staining was carried out by measuring the degree of yellow using the spectro-colour colorimeter {Dr. Lange); colour measurement software: spectrai-QC, version measurement geometry: d/8°, gloss component excluded, type of light: D65 (corresponding to average daylight), calibration standard: LZM 268, measurement aperture: 10 mm, sample background: substrate paper without optica! brightener, test climate: 21 °C (±1°C), 41% (±4%) relative atmospheric humidity.

For the evaluation, the change in the b value from the CIE-Lab colour measurement system was used. The B axis in the CIE-Lab system characterizes the yellow/blue colour impression, where positive b values stand for an increase in the yellow fraction. The higher the b value, the greater the yellow impression.

After the measurement operation, a separate washing of the test cloths was carried out in the dye- and washing-fastness device Linitest Pius (Atlas) (60°C, 1 h, 20 rpm, Ariel Compact power detergent, 10 metal balls as ballast) and then a rinsing operation (20°C, 15 min, tap water).

After drying for 12 h under laboratory conditions, a colorimetric characterization of the resulting staining was carried out again by measuring the colour values as already described using the spectro-colour colorimeter (Dr. Lange).

The CIE-Lab system or L*a*b* colour space is a three-dimensional measurement space in which all perceivable colours are contained. The colour space is constructed on the basis of the opponent colour theory. One of the most important properties of the L*a*b* colour model is its instrument independence, i.e. the colours are defined independently of the nature of their production and display technology.

The corresponding EU guideline is DIN EN ISO 11664-4 “Colorimetry - Part 4: CIE 1976 L*a*b* colour space”. The coordinates of the CIELAB plane are formed from the red/green vaiue a and the yellow/blue value b. The lightness axis L stands perpendicular to this plane. According to DIN 6174, L, a and b should be written with * in order to differentiate them from others, e.g. the “Hunter Lab” system.
