Compositions systems and methods for conferring durable shaping of keratinous fibers

A cosmetic system for durable shaping of keratinous substrates, comprising:

• a. an adhering composition having an acidic to neutral pH, and comprising:
• i. at least one shape memory polymer comprising a three-armed branched polyethylene glycol (PEG) based polymer that is functionalized with one or more metal-coordination active groups;
• and
• ii. a carrier;
• b. a setting composition having an acidic to neutral pH, and comprising one or more metallic coordination agent and a carrier;
• and
• c. a fixing composition having a pH that is greater than the pH of the setting composition by at least Δ pH=1 and comprising a buffer and a carrier.

A process for durably reshaping keratinous substrates, comprising:

• a. treating keratinous substrates under acidic conditions with a coating layer comprising a three-armed branched polyethylene glycol (PEG) based polymer that is functionalized with one or more metal-coordination active groups;
• b. treating the keratinous substrates under acidic conditions with a metallic coordination agent;
• and
• c. shaping the keratinous substrates either before or after step (b),
• wherein the treatments provide durable non-permanent shaping of the keratinous substrate.

An article of manufacture for durable and reversible reshaping of keratinous substrates, comprising packaging that includes a plurality of separate receptacles, the receptacles comprising:

• i. at least one receptacle that contains an adhering composition having an acidic to neutral pH, the adhering composition comprising at least one shape memory polymer comprising a three-armed branched polyethylene glycol (PEG) based polymer that is functionalized with one or more metal-coordination active groups, and one or more chelating agent, in a carrier;
• ii. at least one receptacle that contains a setting composition having an acidic to neutral pH, and the setting composition comprising one or more metallic coordination agent in a carrier;
• and
• iii. at least one receptacle that contains a fixing composition having a pH that is greater than the pH of the setting composition by at least Δ pH=1,
• wherein the receptacles are optionally selected from blister packs, packets, tubes, vials, squeeze bottles, spray bottles, pressurized canisters, non-pressurized canisters, pump dispensers, and combinations of these, the article of manufacture optionally comprising one or more additional receptacles, each of which additional receptacle contains any one or more of:
• (a) a resetting composition comprising (1) at least one or both of (i) a chelating agent or (ii) a buffer that confers an acidic to neutral pH, and (2) a carrier;
• and (b) a cosmetic composition selected from a shampoo, a conditioner, a serum, a colorant, and combinations of these, and
• wherein the at least one shape memory polymer is present in a range from about 0.5% to about 10% by weight, and the chelating agent is present in a range from about 0.001% to about 2% by weight, each based on the weight of the adhering composition, and wherein the metallic coordinating agent is present in the composition in a range from about 0.001% to about 2% by weight, based on the weight of the setting composition.
