Chitosan for hair -
The preparations of the invention may of course also include additional cosmetic additives such as perfuming oils, bactericides and fungicides, combing-improving substances etc.
The preparations may be applied also by means of a spray dispenser or other spray devices or in mixture with a conventional propelling gas from a pressure container. During the application the setting lotions of the invention and the results obtained thereby can further be improved by giving the hair an alkaline aftertreatment.
Such alkaline aftertreatment surprisingly does not reduce the desirable coating or filming properties discussed before but even increases adhesion of the coating to the hair so that even after washing of the hair with a customary shampooing the permanence of the style set after the washing operation is guaranteed and the use of a special hair setting agent which otherwise is customary following the shampooing is not necessary.
The alkaline treatment can be effected with an aqueous or aqueous-alcoholic solution containing such as for instance ammonia, organic amines like monoethanoamine, diethanolamine, triethanolamine or other alkaline reacting compounds, for instance basic reacting salts such as trisodium phosphate or sodium carbonate.
The alkali contents should preferably be about between 0. The carrier material for the alkaline instead of a solution may also be in form of an emulsion or a gel. The hair thereafter exhibited a slight bluish tint.
After treating the hair according to one of the examples 1 to 4 the hair can then be alkalized by moistening the set hair thoroughly prior or after drying with about 20 to 30 ml of the alkalizing solution followed by drying without rinsing.
The following examples will show that alkalization with an alkalizing agent can also be carried out with the agent in a gel or emulsion form. In that case 20 g of the setting agent according to one of the examples 1 to 4 are well spread on the washed and towel-dry hair and the hair is dried under the drying hood.
Thereafter, about 50 to 60 g of an alkalizing agent formed according to the following example b to d are well distributed on the dry hair and permitted to act on the hair for about 3 minutes whereupon the hair is rinsed with water and is set and dried as customary.
All percentages used in this application are intended to refer to percentages by weight. Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.

The materials ability to absorb water was assessed according to the following equation:. The film forming properties of the blends on hair surface were measured by immersing the curly brown human hair of a 26 year old volunteer in polymer solution for 1 h and drying for 24 h at room temperature and humidity.
Mechanical tests for hair were made for hair covered with polymeric films and without such treatment. Analysis was repeated for 10 samples and the standard deviation was calculated.
The surface of human hairs was studied using scanning electron microscope SEM LEO Electron Microscopy Ltd, England. Samples were covered by gold and images were made with the resolution 50 μm. The thickness of hair shafts was calculated for native hair and for hair covered with the polymer film.
Such alterations in infrared spectrum are due to the presence of characteristic groups of hyaluronic acid. Small differences in the position of the main peaks of chitosan and collagen can be observed after mixing with hyaluronic acid which is possibly a consequence of interactions between polymers.
Usually, a small shift is observed when functional groups of biopolymers are involved in hydrogen bonding between them. Results with standard deviations are presented in Figs. Two different liquids were used in this experiment: glycerin and diiodomethane. On the basis of the contact angle measurements, surface free energy and its polar and dispersive components were calculated by Owens-Wendt method.
The results are presented in Table 1. After addition of hyaluronic acid the surface free energy decreases. The polar and dispersive components values depend on the blend composition. The values of the polar component of surface free energy decrease with an increasing amount of HA in the blend.
Hyaluronic acid contains a number of carboxylic and hydroxyl groups which can form hydrogen bonds with water as well as with collagen and chitosan [ 22 ]. As a result of such interactions the hydrophilic character decreases due to the lower number of free carboxylic and hydroxyl groups present on the surface.
Films were immersed in PBS solution for 0. After gently drying, the samples were weighed. Swelling tests allow us to observe changes in the blends behavior in aqueous conditions. Addition of hyaluronic acid improves the swelling in time initially, nevertheless after 24 h the films swelling decreases compared to the samples without it.
The topography of the film surface was detected by atomic force microscopy. Moreover, the roughness was calculated and listed in Table 3. As the results show, the addition of hyaluronic acid increases the roughness of the film surface.
It may cause the improvement of the surface contact area with any agent to be applied to the top of the film. Samples of human hair were cut from the hair shaft without any chemical treatment. Hair were immersed in polymeric mixture for 1 h and then dried at room temperature and humidity for 24 h.
The mechanical tests were made and the results are shown in Table 4. Addition of hyaluronic acid improves the mechanical parameters of hair, which is a result of film formed on the hair surface. Hydrogen bonds can be formed between side groups of keratin present in hair and functional groups of collagen, chitosan and hyaluronic acid.
Moreover electrostatic interactions are possible between hair components and biopolymers. The thickness of hair shafts with and without polymer covering was calculated from the SEM images in three places and it is shown in Table 5.
SEM images of hair shafts are shown in Figs. The thickness of a hair shaft with the polymer covering is bigger than without it. SEM images showed that scales of hair are more detached in a shaft without the polymer covering.
It can be noticed that the increasing hyaluronic acid content decreases the scales detachment. It may suggest that such a composition of the blends leads to the formation of film with very good adhesion to the hair surface.
Nevertheless, for each studied composition of the mixtures, an increase of hair shaft thickness was observed. This suggests that the polymer mixture is adsorbed on the hair surface and a smoothing of hair can be observed. When the hair surface is smooth, the general appearance of the hair is better.
In general, as conditioning agents for hair, biopolymers have no effect on growth and cannot affect cellular repair, however, they can temporarily improve the cosmetic appearance of damaged hair.
There are several mechanisms by which conditioners can improve the cosmetic appearance of a weathered hair shaft. They can increase shine, decrease static electricity, improve hair strength and protect against ultraviolet radiation.
Biopolymeric films formed on the surface of the hair shaft help hair to look and feel better by improving the physical condition of these surfaces. Hair covered by biopolymeric film has a greater volume than those which are non-treated which leads to the reduction of the force required when combing and flyaway hair which, in turn, leads finally to an improved manageability of hair.
The thickness of hair shafts without and with covering by biopolymers mixture, where CS is chitosan, Col is collagen, HA is hyaluronic acid. Triple component blends of chitosan, collagen and hyaluronic acid can be obtained in the thin film form through solvent evaporation.
Mechanical properties, for example, in addition to, swelling, surface free energy, and the roughness of blends depend on their composition. The increasing chitosan content improves mechanical parameters, surface free energy and the stability in aqueous conditions.
The addition of hyaluronic acid improves the mechanical resistance to the applied force. Moreover, the blends are more stable in aqueous conditions which means that such materials will not immediately dissolve after wetting with water. The presence of hyaluronic acid in the sample leads to a decrease of surface free energy and to an increase of roughness.
Triple component blends of chitosan, collagen and hyaluronic acid can cover the hair surface well. The covering of hair with triple component blends of chitosan, collagen and hyaluronic acid leads to an increase in hair thickness and to the improvement of its mechanical properties.
Overall, this leads to an improvement in the general appearance and conditioning of the hair.

Chhitosan, a natural polymer hCitosan from chitin, Chitosaj substance naturally present in Chitosan for hair shells of crustaceans like prawns and crabs, has several advantages when added to skincare products. This blog provides an overview of its roles and properties. Chitin, a material present in the exoskeletons of crustaceans including prawns, crabs, and lobsters, is the source of the natural polymer chitosan.Chitosan for hair -
The amount of acid preferably is chosen to obtain sufficient neutralization of the free amino groups of the initial chitosan.
A small excess of the acid during the neutralization has no effect on the usefulness of the final compound. The invention also embraces hair setting preparations of the type described which at the same time include directly acting dyestuffs in order to obtain a setting and dyeing of the hair at the same time.
These preparations are usually sold as color fixation agents or tinting agents. Among these color fixatives which may be used individually or as mixtures the following classes are mentioned here by way of illustration: aromatic nitro dyes for instance 1,4-diaminonitrobenzene , azo dyes for instance C.
Acid Brown 4 , anthraquinone dyes for instance C. Disperse Violet 4 and triphenylmethane dyes for instance C. Basic Violet 1. The dyes of these groups according to their substituents may have acid, nonionic or basic character. Their total concentration in the preparation normally is between about 0.
The preparations of the invention may of course also include additional cosmetic additives such as perfuming oils, bactericides and fungicides, combing-improving substances etc.
