The present invention relates to the use of at least one cyclohexanol derivative of the formula (I) and/or (II) as antimicrobial active compound or as anti-acne, antidandruff, antiperspirant or deodorant active compound, to preparations comprising these compounds, and to specific cyclohexanol derivatives and to a process for the preparation thereof.

Use of cyclohexanol derivatives as antimicrobial active compounds

The present application relates to an electronic device comprising a heteroaromatic compound of a formula (I) as functional material, in particular as electron-transport material and as matrix material for emitter compounds. 

Electronic device

The invention relates to protein-adhesive dyes, to the preparation thereof and to preparations comprising same, and to a method for coloring keratin-containing fibers, in particular for coloring human hair.

Substituted quinones or analogues as colouring agents

The present invention relates to the use of at least one dicyclohexylmethanol derivative of the formula (I) as antimicrobial active compound or as anti-acne, antidandruff, deodorant or antiperspirant active compound, to preparations comprising these compounds, and to specific dicyclohexylmethanol derivatives and to a process for the preparation thereof.

Use of dicyclohexylmethanol derivatives having antimicrobial properties

The invention relates to the use of at least one ascorbic acid derivative for the fictionalization of matrices, and to specific ascorbic acid derivatives and processes for the preparation thereof.

Use of ascorbic acid derivatives for the functionalization of matrices

The invention relates to specific benzodioxepin-3-one compounds, to a process for the preparation thereof and to the use thereof as dyes or as fluorescent emitters for organic electroluminescent devices (OLEDs) or for organic light-emitting electrochemical cells (OLECs), and to corresponding electronic devices.

Benzodioxepin-3-one compounds as dyes or as fluorescent emitters

The invention relates to specific dye-ascorbic acid derivatives and the use thereof as dyes for the coloring of matrices, such as, for example, skin, hair, nails or textiles, and a process for the preparation thereof, a process for the coloring of matrices, and a composition comprising these dye-ascorbic acid derivatives, and a process for the preparation of these compositions. On use of the specific dye-ascorbic acid derivatives according to the invention, a positive effect on the moisture content of the matrices arises.

Dye-ascorbic acid derivatives

The invention relates to the use of specific ascorbic acid derivatives for dyeing keratin-containing fibers or as direct dyes for the preparation of a composition for dyeing keratin-containing fibers, and to methods for dyeing keratin-containing fibers, in particular for dyeing human hair.

Use of ascorbic acid derivatives for dyeing keratin-containing fibres

The invention relates to the use of at least one flavonoid having an uncharged flavan skeleton as synergist for enhancing the action of self-tanning substances, such as trioses and tetroses, in cosmetic and dermatological formulations and to corresponding novel compositions and to the preparation thereof.

Flavonoids as synergists for enhancing the action of self-tanning substances

The invention relates to specific cinnamic acid ascorbates and to the use thereof as UV filters which bond to the skin, and to a process for the preparation thereof, and to preparations comprising these compounds.

Cinnamic acid ascorbates

The invention relates to the use of &#x3b1;-amino acid derivatives for improving the solubility of sparingly soluble substances in water or aqueous solutions, and to mixtures and preferred compositions.

&#x3b1;-amino acid derivatives for improving solubility

The present invention relates to the use of compounds which do not themselves exhibit significant UV absorption in the UV-A or UV-B region, but are reactive under use conditions, for the development of UV-A or UV-B protection during use, to corresponding novel compounds and compositions, and to corresponding processes for the preparation of compounds and compositions.

UV protection

The present invention relates to the use of compounds of the formula (I), with radicals defined in the description, as antioxidants, to corresponding novel compounds and compositions, and to corresponding processes for the preparation of compounds and compositions.
