Methods for using such cosmetic compositions are also provided.

Disclosed herein is an agent for shaping or altering the shape of hair, such as by straightening or relaxing hair, the agent comprising: A. a hair treatment composition containing an alkaline material selected from a hydroxide-containing compound and a carbonate compound; a cationic polymer selected from a quaternary diammonium polycondensate; an amphoteric polymer selected from a quaternary ammonium compound; an organic solvent, and water; and optionally, B. an activator component; wherein the pH of the composition is equal to or greater than 12 and wherein the weight ratio of (b) to (c) ranges from about 1 up to about 3.

Provided is a polymer-based antimicrobial composition that is non-toxic, water soluble, and that mitigates the transmission of infectious diseases from surfaces. The composition comprises a cationic polymer, at least one adhesion promoter, optionally organic and/or inorganic particles that are photocatalytically active in visible light, and a carrier, in which the components of the composition are not covalently bound to one another. Also provided is an antimicrobial composition that comprises at least (i) a polyethylenimine-based polymer and a carrier or (ii) an organic and/or inorganic particle that is photocatalytically active in visible light, an adhesion promoter, and a carrier. The antimicrobial compositions can be applied to disinfect a surface and to form residual self-sanitizing films on the surface that are removable.

Disclosed is a composition comprising, in an aqueous phase: a) at least one ether of formula (I): R—O—R′ in which R and R′, which may be identical or different, denotes a linear or branched C.sub.6-C.sub.25 alkyl or alkenyl radical, R and R′ being chosen such that the ether is liquid at a temperature of less than or equal to 30° C.; b) at least one surfactant chosen from anionic surfactant, amphoteric or zwitterionic surfactant, or a mixture thereof; c) at least one cationic alkyldiallylamine or dialkyldiallylammonium cyclopolymer; and d) soybean oil.

Provided are a pigment dispersion liquid for cosmetics having excellent dispersibility of carbon black and aging stability, and an aqueous liquid cosmetic using the same, which is suitable for hair dyes and the like. The pigment dispersion liquid for cosmetics contains, at least, water, a water-soluble organic solvent, carbon black, and a (methacryloyl ethylbetaine/acrylates) copolymer, and a ratio of the water to total solvents is 30 to 95% by mass.

The present invention describes a novel natural hair colour composition containing (a) a mixture of basic salt which aid in opening the hair cuticle and facilitating better penetration of dye which is natural plant-based extract; (b) a metal salt based mordanting agent which form a dye-metal complex. The invention further describes 2 step method of application which give better penetration and hence improved colour delivery and wash off resistance.

The instant disclosure relates to hair coloring base compositions and developer compositions that can be incorporated into a hair color cartridge, which combines the compositions and dispenses them onto hair. The hair color cartridge includes: (a) one or more hair coloring base compositions and; (b) one or more developer compositions, which can be combined to form an active hair coloring composition and dispensed onto hair. The hair coloring base compositions typically include one or more oxidative dye precursors; one or more alkalizing agents; one or more reducing agents; optionally, one or more cationic conditioning polymers; one or more surfactants; one or more water-soluble solvents; and water. The developer compositions typically include one or more oxidizing agents; one or more surfactants; and water. The unique components and fluid characteristics of the various compositions are such that devices or appliances comprising them accurately combine and dispense the hair coloring base composition(s) with the developer composition(s) in a predetermined ratio with excellent consistency for application to hair.

Described herein are lipstick compositions that are substantive, aesthetically appealing, do not pool on the lips, are easy to spread, and moisturize the lips. The compositions comprise cosmetic ingredients such as conditioning agents, moisturizing agents, antioxidants, structuring agents, emulsifiers, silicone containing compounds, essential oils, thickening agents, preservatives, and colorants, for example.
