Non-chemical smoothing and de-curling agents

A two-phase liquid agent for the non-chemical smoothing and de-curling of keratin fibers, having a pH value of from about 4 to about 6 and having an aqueous-alcoholic phase that is continuous and is present in an amount of about 80% by weight of the liquid agent and a non-aqueous phase that is continuous and is present in an amount of about 20% by weight of the liquid agent and wherein the aqueous-alcoholic phase and the non-aqueous phase exist separately from one another, the agent comprising:

• (a) at least one care substance liquid at 20 ° C. consisting of at least one protein hydrolyzate and/or derivative of a protein hydrolyzate, in a total amount of about 2.2 to about 2.5% by weight;
• at least one quaternary ammonium compound in a total amount of about 2.4 to about 2.5% by weight;
• and glycerine in a total amount of from about 1.6 to about 2.5% by weight,
• (b) ethanol in a total amount of from about 21 to about 25% by weight,
• (c) about 45 to about 55% by weight of water, and
• (d) cyclopentasiloxane and octamethyltrisiloxane, in a total amount of from about 18 to about 22% by weight,
• wherein:
• the liquid agent is free of solid fatty substances at 20 ° C.,
• the quantity value for each component is based on the total weight of the liquid agent, and
• the liquid agent is not an oil-in-water or water-in-oil emulsion.
