This invention relates to a delivery system for hydrophobic benefit agents to keratinous substrates. The delivery system comprises amphiphilic block copolymers, and a hydrophobic benefit agent, which amphiphilic block copolymers comprise a siloxane segment and a cationic segment. The invention also relates to methods of delivering the hydrophobic benefit agents to the keratinous substrate. Furthermore, the delivery systems and methods of delivery are effective in retaining an hydrophobic benefit agents on the keratinous substrate after rinsing. More particularly, the delivery systems are especially suitable in personal cleansing, body wash or rinse off lotion compositions and comprise certain amphiphilic polymers which effectively deposit the hydrophobic benefit agents onto a keratinous substrate, such as skin or hair.

A coating, preferably a color coating, method for keratin fibers is described which includes three steps: activation, pretreatment and binding. The activation step includes one or both of a Praeparatur procedure and a Fundamenta procedure to produce modified fibers. The pretreatment step applies a pretreatment composition of at least a PTH alkoxysilane with PTH as a thiol, a protected thiol or a group complementarily reactive with thiol to the modified fibers to form pretreated fibers. The binding step applies a film forming composition to the pretreated fibers to form the color coating.

Disclosed is a hair conditioning composition comprising: a cationic surfactant; a high melting point fatty compound; a cyclic compound selected from the group consisting of a vitamin B3 compound, a xanthine compound, a salicylic acid ester, and mixtures thereof; a compound having at least three large head groups; and an aqueous carrier. The composition of the present invention provides improved hair manageability.

Disclosed is a hair conditioning composition having a Max force peak value of at least about 58, and a Viscosity change value of at least about 800. The composition of the present invention provides reduced slimy feel on wet hair while providing conditioning to wet hair.

Disclosed is a hair conditioning composition comprising from about 0.1% to about 20% by weight of a silicone compound, and wherein the composition has a Silicone deposition amount of at least about 1,600, and Silicone deposition evenness value of at least 0.83. The composition of the present invention provides improved hair manageability.

The invention is directed to a cosmetic which comprises an ionic silicone as described herein.

The invention is directed to a cosmetic which comprises an ionic silicone as described herein.

To provide a resin for hair cosmetic which is free from stickiness and highly compatible in fixing properties and combing properties without impairing performances such as water resistance, colorability and washability, and to provide a hair cosmetic. The hair cosmetics resin is obtained by bonding a poly(N-acylalkyleneimine) segment (b) comprising a repeating unit represented by formula (1) to at least two silicon atoms of an organopolysiloxane segment (a) constituting a main chain via an alkylene group containing a hetero atom, wherein the alkylene group containing a hetero atom is either a group represented by formula (i) or (ii), the mass average molecular weight of the segment (a) is 10,000 to 100,000, the number average molecular weight of the segment (b) is less than 800, and the mass ratio of (a) to (b) [(a)/(b)] is 58/42 to 90/10. [In formula (1), R1 represents a hydrogen atom, C1-22 alkyl group, aralkyl group, or aryl group, and n represents 2 or 3.]
