Definitions
- the invention relates to the use of compounds from the group of (2-hydnoxyphenyl) alcohols and their derivatives for lightening skin and / or hair, and to cosmetic or therapeutic formulations which contain the compounds.
- the usually brown to black colored melanin pigments are formed in the melanocytes of the skin, transferred to the keratinocytes and cause the coloring of the skin or hair.
- the brown-black eumelanins are mainly formed from hydroxy-substituted aromatic amino acids such as L-tyrosine and L-DOPA, the yellow to red phaeomelanins are additionally formed from sulfur-containing molecules (Cosm ⁇ tics & Toiletries 1996, 111 (5),
- L-tyrosine the copper-containing key enzyme tyrosinase L-3,4-dihydroxyphenylalanine (L-DOPA) is formed, which in turn is converted to dopachrome by tyrosinase.
- L-DOPA tyrosinase L-3,4-dihydroxyphenylalanine
- the latter is oxidized to melanin through several steps catalyzed by different enzymes.
- Skin-lightening agents are used for various reasons: If the melanin-forming melanocytes in the human skin are not evenly distributed for any reason, pigment spots appear that are either lighter or darker than the surrounding skin areas. To remedy this problem, skin and hair lightening agents are available on the market that help to at least partially compensate for such pigment spots. There is also a need for many people to lighten their naturally dark skin tone or to prevent skin pigmentation.
- UV-absorbing substances are also used to protect against the increase in skin pigmentation induced by UV light.
- this is a purely physical effect and must be distinguished from the biological effect of skin-lightening agents on the cellular melanin formation, which can also be demonstrated in the absence of UV light.
- UV absorbers also do not really lighten the skin, but only prevent the increase in skin pigmentation induced by UV light.
- hydroquinone In commercial cosmetic or therapeutic skin and hair lightening formulations, hydroquinone, hydroquinone derivatives such as e.g. Arbutin, vitamin C, derivatives of ascorbic acid such as e.g. Ascorbyl palmitate, kpjic acid and derivatives of kojic acid such as Kojic acid dipalmitate used.
- Hydroquinone has a cytotoxic effect on melanocytes and is irritating to the skin. Therefore, such preparations are not, for example, in Europe, Japan and South Africa for cosmetic applications more permissible. In addition, hydroquinone is very sensitive to oxidation and is difficult to stabilize in cosmetic formulations.
- Arbutin is a hydroquinone glucoside that hydrolyzes to hydroquinone in situ and is therefore toxicologically as harmful as hydroquinone.
- Vitamin C and ascorbic acid derivatives have an insufficient effect on the skin. They also do not act directly as tyrosinase inhibitors, but reduce the colored intermediate stages of melanin biosynthesis.
- Kojic acid (5-hydroxy-2-hydroxymethyl-4-pyranone) is a tyrosinase inhibitor which inhibits its catalytic action by chelating the copper atoms of the enzyme; it is used in commercial skin and
- Hair lighteners used but has a high sensitizing potential and causes contact allergies.
- Salicin is widely used in cosmetics as an active ingredient against wrinkles, old, dry and rough skin, as well as protection against inflammation and to promote wound healing.
- JP 2002275060 A2 describes salicylic acid and salicyl alcohol derivatives as active ingredients which stimulate skin tanning.

After 24 h of cultivation at 37 ° C. and 5% CO 2 in RPMI medium, enriched with 10% fetal calf serum, various concentrations of the test substances as well as 0.3 mM tyrosine and 10 nM ⁇ -MSH ( ⁇ -melanocyte stimulating hormones) are added and incubated for another 96 h. The maximum use concentration of the test substances corresponds to 0.1 times the value of the respective IC2o value of the cytotoxicity assay.
- incubation is carried out with kojisaure as standard in concentrations of 0.01 mM, 0.1 mM and 1 mM. After the incubation, the culture medium with SDS and NaOH (Final concentrations: 1 mM or 1 M) added and the absorption (A) measured after 3 h at 400 nm.
- the IC » is calculated for each test compound from the inhibition of pigmentation (%) in a series of dilutions of test compounds. This is the concentration of a test compound at which pigmentation is inhibited by 50%.
