Compositions for treating keratin fibers are described. These compositions provide an anti-frizz effect to hair while reinforcing and repairing hair as well as protecting hair from damage during heat treatments (heat-protection).
The information provided below is not admitted to be prior art to the present disclosure, but is provided solely to assist the understanding of the reader.
Human hair is structured in highly organized strata that are very resistant to external stimuli. Its high stability is due to stiffness of the central α-helical core of keratin and to a high number of disulfide crosslinks.
Although weather and oxidants (i.e., environmental factors) can give rise to hair damage, morphological changes can result from daily care routines. In particular, permanent wavings, straightening or relaxing and bleaching during hair coloring processes are major causes of hair damage. These alterations results in poor manageability, dryness, brittleness, loss of shine and decreased strength (fiber breakage).
Heat-assisted styling of human hair, particularly using blow dryers, hair straighteners (flat irons), curling devices, heated combs, heated brushes (with or without a rotating drum), or other heating means, can also damage hair by subjecting the hair to too much heat.
The overheating causes moisture to evaporate or be driven out of the hair so that the hair becomes brittle and more susceptible to cracking. In addition, overheating in heat styling can cause physical damage to the hair, particularly by raising the cuticles and/or creating blisters on individual hair fibers, thus causing increased friction between the hair fibers. As a result, hair develops a positive electrostatic charge. The positive charge of individual hair fibers causes the hair fibers to repel one another resulting in a “static flyaway” condition (i.e., frizzy hair), making it more difficult to comb, requiring increased force to comb the hair, which in turn can wear the outer surface of the hair and cause cracks and breaks in the hair.
There is therefore a need for hair treatments that can provide an improvement of the fatigue lifetime of hair, especially hair that has been subjected to adverse conditions or treatments, particularly hair treatments that provide an anti-frizz effect to hair as well as protecting hair from damage during heat treatments (heat-protection), and to do so in a long-lasting manner.

In one embodiment, the compositions for treating keratin fibers are “leave-on” compositions. The term “leave-on” as used herein refers to compositions that contain ingredients that are intended to be deposited and left on the hair for extended periods (i.e. several hours or days) until the ingredients are subsequently removed by water and/or shampooing the hair.
No particular limitation is imposed on the form of the compositions for treating keratin fibers of the present disclosure. Examples include hair sprays, setting lotions, mousses, gels, waxes, creams, pomades, gums or serums (Thomas Clausen et al., Hair Preparations, Ullmann's Encyclopedia of Industrial Chemistry, 2006).
In embodiments, the compositions are formulated as a hair spray, setting lotion or mousse.
Hair sprays may be aerosol sprays, which may be two-phase aerosols in which both a liquid and a gaseous phase are present inside the container; or pump sprays (non-aerosol sprays), which do not employ a propellant gas and the energy needed to swirl and atomize the liquid must be supplied by a pump, which is operated with a finger or through a lever.
Setting lotions may be thin, aqueous-alcohol solutions in single- or multiple-application packages.
Mousses may be thin, aqueous or aqueous-alcohol solutions in, for example, alumina cans with a propellant; or non-aerosol mousses, where the mousse is generated through use of a squeeze or pump dispenser with a riddle in the head of the pump. The liquid is mixed with air in the head of the pump and dispensed as mousse.
The pH of the compositions for treating keratin fibers of the present disclosure may be in the range of about 5.5 to about 8.5, or in the range of about 6.0 to about 8.0.
The following examples are given in order to provide a person skilled in the art with a sufficiently clear and complete explanation of the present disclosure, but should not be considered as limiting of the essential aspects of its subject, as set out in the preceding portions of this description.
The compositions as shown in Table 1 and Table 2 were prepared by mixing and stirring until complete homogenization in a kettle. Compositions C1 to C3 (Table 1) are compositions according to the present disclosure. Compositions CC1 to CC6 (Table 2) are comparative compositions.
Strands of virgin dark Caucasian hair were selected, each one approximately 22 cm long.
24 hours prior to the treatment, the strands were washed with a shampoo and rinsed under tap water according to the following process:
The strands of hair of step 2.1 were damaged according to the following process:
The compositions for treating keratin fibers C1-C3 and the comparative compositions CC1-CC6 of Ex. 1 were applied to the strands according to the following process:
11 locks of hair from each strand (approximately 1.2 g each lock) were selected.
9 locks of hair were immersed for 10 minutes in each of the following solutions:
All the hair locks were combed to untangle them and to spread the compositions uniformly.
All hair locks were dried for 6 minutes using a Pro-Iron 3000 City dryer manufactured by Tectools. The hair locks were not combed.
All hair locks were straightened 5 times, 4 seconds each time, using a Titanium Ion Technology flat ironing manufactured by GA.MA S.r.l. The hair locks were not combed.
Pictures were taken of each hair lock and the width of each hair lock was measured.
Treated and untreated hair locks were kept at 25° C. and 80% relative humidity in a HPP750 climatic chamber manufactured by Memmert GmbH & Co. KG.
Pictures were taken of each hair lock and the width of each hair lock was measured at 24 h.
The frizz reduction factor (FRF) was calculated according to the following equation:
% of width of the untreated hair lock={[Wuh(24h)−Wuh(0h)]/Wuh(0h)}×100
% of width of the treated hair lock={[Wth(24h)−Wth(0h)]/Wth(0h)}×100
The results are shown in Table 3. Each value represents the mean of 5 hair locks.
FRF positive values show a reduction in the frizz with respect to the untreated hair locks. FRF negative values show an increase in the frizz with respect to the untreated hair locks.
From the experimental results, it can be concluded that the compositions for treating keratin fibers of the present disclosure provide an anti-frizz effect to hair at least after 24 h of application. The compositions for treating keratin fibers also protect hair during heat treatments (heat-protection).
Modifications, which do not affect, alter, change or modify the essential aspects of the compositions and methods described above, are included within the scope of the present disclosure.
