The present invention relates to a cleaning liquid, in particular a cleaning liquid for cleaning surfaces and/or for sanitising water.

Provided are largely aqueous topical antimicrobial cleaning composition which provides an antimicrobial benefit, as well as methods for their production and methods for their use. The compositions comprise at least two different cationic surfactants which provide a primary antimicrobial benefit, and as a predominant further surfactant an amine oxide surfactant. The composition are at an acidic pH and are highly effective in providing an antimicrobial benefit to topical surfaces, e.g, epidermis and hair.

The present invention relates to a cleaning liquid, in particular a cleaning liquid for cleaning surfaces and/or for sanitizing water.

An agent for oxidatively dyeing keratinous fibers, in particular human hair, containing, in a cosmetic carrier, at least one oxidation dye precursor or the developer type, isatin, and at least one oxidizing agent and related systems and methods.

The present invention relates to an agent for oxidatively dyeing keratin fibers, and in particular human hair, containing, in a cosmetic carrier, (a) at least one oxidation dye precursor of the developer type, and (b) isatin, and (c) at least one alkalizing agent from the group consisting of ammonia, monoethanolamine, 2-amino-2-methylpropanol, arginine, lysine, ornithine, and histidine.

A cosmetic agent for dyeing keratinous fibers, especially human hair, includes at least one specific protein-siloxane polymer and at least one oxidation dye precursor and/or a direct dye, where the use of the at least one protein-siloxane polymer leads to improved care of the keratinous fibers. A corresponding packaging unit (kit of parts) and a method for dyeing keratinous fibers include the cosmetic agent. Lastly, the cosmetic agent is used to care for keratinous fibers with an enhanced care effect.

A hair dye composition is characterized by containing (A) HC BLUE No. 2, (B) DISPERSE VIOLET 1, and (C) at least one of HC YELLOW No. 2 and HC YELLOW No. 4 and has a pH of 7-11. The mass ratio of the content of (A) HC BLUE No. 2 to the content of (B) DISPERSE VIOLET 1 is preferably 1 to 30. The hair dye composition preferably further contains (D) DISPERSE BLACK 9.

Compositions containing a quaternary ammonium compound (QAC) active to provide an antimicrobial property, a quaternized phospholipid which provides a reduction in potential irritancy of other ingredients as well as foaming and cleansing properties, a second non-ionic or amphoteric surfactant (such as an alkyl amine oxide or linear alkyl polyglucoside) to provide increased foam volume and cleansing properties, a non-ionic or quaternized polymer (such as hydroxypropylmethylcellulose or hydroxypropyl guar hydroxypropyl trimonium chloride) which can provide thickening, foam structure and improved after-feel properties are described.

Disclosed are methods and compositions for altering the color of hair, comprising treating the hair with a pre-alkalizing composition and then treating the hair with a color-altering composition comprising at least one direct dye and optionally at least one oxidative dye precursor.

The present invention relates to substituted stilbenes and dienones which exhibit unexpected dual activity, as inhibitors of NFB and as agonists (activators) of Nrf2. In particular, these compounds show dual activity and it has been discovered that these compounds are particularly useful in the treatment of certain cosmetic applications and in rejuvenating and beautifying skin and other keratinous tissue of a subject in need. Cosmetic compositions and methods of using said compositions in combination with other components are disclosed herein.
