Problems solved by technology

However, a severe disintegration of the hair fiber was observed, presumably related to the polymerization initiator, so that the treated hair was difficult to untangle

Embodiment 1

[0172] The following compositions according to the invention were prepared:

[0173] - 2-Octyl cyanoacrylate (1) 49%

[0174] - Polymethylmethacrylate (2) 50%

[0175] - Monoethanolamine 1%

[0176] (1) Sold by Chemence Corporation

[0177] (2) Polymethyl methacrylate balls, Acros Chemical, catalog number (reference) 178765000

[0178] The composition was deposited on a Teflon substrate. The film was dried at room temperature and 50% relative humidity. The obtained film had a thickness of 0.5 mm.

[0179] The Young's modulus of the obtained film was then measured using a Lloyd model RLSK machine at a stretching speed of 20 mm / min. This value is about 200MPa.

[0180] The composition is applied to the hair and dried to give a wash-resistant hard coat.

Embodiment 2

[0182] This example demonstrates the rigidity of the films obtained using the compositions according to the invention.

[0183] The following compositions were used according to the invention.

[0184] Composition A: Methylheptyl cyanoacrylate monomer, oily silicone medium and PVP polymer.

[0185] Composition A1:

[0186] - Polyvinylpyrrolidone Luviskol 5% from BASF

[0187] -Water up to 100

[0188] Composition A2:

[0189] - Methylheptyl cyanoacrylate (1) 10%

[0190] -DC 245 Fluid, 45% from Dow Corning

[0191] -DC 1501 Fluid, 45% from Dow Corning

[0192] (1) Sold by Chemence Corporation

[0193] Composition A1 is applied to clean, damp hair. Composition A2 was then applied. Hair was then dried under a drying hood for 30 minutes.

[0194] Composition B: methylheptyl cyanoacrylate monomer, oily silicone medium and PS polymer.

[0195] Composition B1:

[0196] - Polystyrene dispersion, Modarez OS-197, 5% from Synthron

[0197] -Water up to 100

[0198] Compositi...

Abstract

A use for cosmetically treating a keratinic material with a film-forming composition comprising at least one electrophilic monomer and at least one non-siloxane polymer in a cosmetically acceptable solvent (consequently, a film obtained by drying the composition at room temperature at a relative humidity level of about 50 % has a Young's modulus of 100 to 2,000 MPa in a thickness of 0.5 mm at a pulling speed of 20 mm / min).

Description

technical field [0001] The present invention relates to the use of a film-forming composition comprising at least one electrophilic monomer and at least one specific non-silicone polymer for the cosmetic treatment of keratinous substances, and to a cosmetic treatment method using the composition. Background technique [0002] In the field of cosmetology, efforts have been made to modify the surface properties of keratinous substances such as keratinous fibers such as hair, for example in order to provide hair conditioning benefits such as softness or shine. Cosmetic compositions based on conditioners such as silicones or polymers which have a high affinity for keratinous substances, especially hair, are commonly used. [0003] However, the coatings obtained from these compositions on keratin fibers such as hair often have the disadvantage of an unpleasant sticky feeling and transferability, for example when one runs one's hands through the hair. This transfer phenomenon can...
