"PROCESS TO PERFECT HAIR TREATMENT" FIELD OF THE INVENTION

The present invention relates to aqueous compositions which are suitable as shampoos. The composition comprises an oil and provides an interesting hair treatment, in particular an interesting hair treatment that targets damaged hair. BACKGROUND OF THE INVENTION

Shampoo compositions are designed to provide certain benefits, including cleaning. These are usually aqueous compositions. The conditioning compositions are designed to provide some additional hair treatment. Some compositions are designed to provide both cleaning and treatment benefits. They are often referred to as 2 in 1 shampoos (cleaning and conditioning). Some shampoo compositions are designed to provide benefits on virgin hair and / or damaged hair.

Various compositions have been exposed in the literature and / or have been made available to consumers. Shampoos typically comprise surfactants, usually anionic surfactants in the form of aqueous micellar solutions. The use of silicone in hair compositions is known. The use of cationic polymers in shampoos is also known. Some silicone oil is believed to be deposited on the hair in order to provide hair treatment. It is believed that cationic polymers may aid in the deposition of silicone oil.

[0004] The use of cationic surfactants in conditioners to provide hair treatment benefits is known.

Recently, cosmetic products, in particular skin cleansing products, such as body wash products comprising structured surfactant systems have been developed and marketed. These cosmetic products are capable of suspending high oil loads that can treat the skin and have an interesting rheology and / or appearance and / or sensory profile. Structured surfactant systems are typically based on an appropriate combination of anionic surfactants and structurants. Such cosmetic products are, for example, described in EP 586275 and WO 03/055456.

There is a need for improved aqueous compositions suitable as shampoo, in particular as 2 in 1 shampoos, which provide improved treatment of hair, especially damaged hair. When hair comprises damaged hair and virgin hair, there is a need for compositions that target damaged hair in order to provide further enhancement to damaged hair than to virgin hair.

BRIEF SUMMARY OF THE INVENTION

The invention addresses at least one of the above needs with an aqueous composition comprising: a) a structured surfactant system comprising: - non-cationic surfactant (s), and - a cationic surfactant; b) an oil, wherein: b1) a silicone oil, or b2) an oil of mineral origin, and c) optionally a cationic or anfolitic polymer.

The makeup allows an improved treatment of damaged hair. The invention also allows for improved selectivity of treatment to damaged hair compared to virgin hair. The invention also allows objectification of damaged hair. The invention also allows an improved ratio of; Damaged hair treatment / Virgin hair treatment.

Improved treatment of damaged hair and / or selectivity and / or reason may allow large amounts of the composition to be avoided. It can reduce the frequency of use of the makeup. It can prevent deposition of build-up, especially in virgin hair, which does not require much treatment.

The introduction of cationic surfactants into typical compositions comprising micellar surfactants has been found to decrease the oily treatment, while the oily treatment is surprisingly increased when the composition comprises a structured surfactant system. The introduction of a cationic surfactant in compositions comprising a structured surfactant system has been found to surprisingly increase the selectivity of treatment to damaged hair.

The invention also relates to a process for preparing the composition. The invention also relates to the use of the composition to treat hair, especially damaged hair. The invention also relates to a process for improving hair treatment by depositing an oil on the hair, which comprises the stage of applying the composition to the hair.

DETAILED DESCRIPTION OF THE INVENTION

The aqueous composition of the invention comprises several ingredients, which are detailed below.

In the present applications, unless otherwise provided, the amounts express a% of active substance by weight as opposed to "as such" quantities.

Structured Surfactant System The structured surfactant system is a mixture of components including a surfactant component and optionally other components such as an electrolyte. The components and amounts thereof are such that the system forms ordered liquid crystals in the composition. As the composition comprises a structured surfactant system, it may also be referred to below as a "Structured surfactant composition".

The structured surfactant system is capable of imparting some composition-specific properties (in the presence and / or absence of additional ingredients, such as b and / or c), in the same active content), some of which are discussed below and which can be considered as a signature of the presence of a structured surfactant system.

Structured surfactant compositions are liquid crystalline compositions having an ordered liquid crystal structure. Surfactants in structured surfactant compositions exist in the form of lamellar surfactant phases, which are planar and / or spherulite (also referred to as multilamellar vesicles). Commonly, the surfactant phase is present as spherulites, i.e. lamellar droplets, dispersed in the aqueous phase. The spherulites consist of an onion-like configuration of concentric bilayers of surfactant molecules, among which water and electrolyte solution are retained. Exclusively planar lamellar surfactant phases or exclusively spherulite lamellar surfactant phases or the combination of both forms may coexist in the same composition. Structured surfactant compositions are typically pumpable non-Newtonian compositions which have the ability to physically suspend water-insoluble particles by virtue of the presence of these lamellar surfactant phases. As referred to herein, "lamellar surfactant phases" are phases comprising a plurality of stacked surfactant bilayers separated by a liquid medium. Lamellar phases are typically anisotropic, non-Newtonian, pourable compositions that are turbid to the eye and exhibit a "waxy" appearance when flowing. Lamellar phases may exist in a number of different forms, including planar layers of parallel sheets, each sheet being a surfactant bilayer, and spherulites formed from concentric spherical shell layers, each bark being a surfactant bilayer. Spherulites are typically between 0.1 and 50 microns in diameter and thus differ fundamentally from micelles. Thus, the structured surfactant system may typically have the following: - planar lamellar phases, - multilamellar vesicle phases, or - a mixture of planar lamellar and multilamellar vesicle phases.

In one embodiment, the presence of a surfactant phase having an ordered liquid crystal structure is indirectly demonstrated by demonstrating that the composition (or structured surfactant system) has an opaque visual appearance and a yield strength of more than 0 Pascal. Thus, the structured surfactant system and / or composition has an opaque visual appearance and exhibit a yield strength of more than 0 Pa.

In one embodiment, the composition exhibits shear thinning viscosity. In one embodiment, the composition is capable of suspending insoluble or partially insoluble components.

In many cases, it is possible to directly demonstrate the presence of a liquid crystal surfactant phase (typical of a structured surfactant system) through the technique of “freeze fracture microscopy” in which the composition sample is frozen. upon exposure to low temperature, the frozen sample is fractured, and one or more of the fractured surfaces of the frozen fractured sample are examined under a microscope.

It is also possible to indirectly demonstrate the presence of an ordered liquid crystal surfactant phase (or to demonstrate that the surfactant system is of the structured type) by inference based on the unique combination of properties exhibited by a composition comprising such a phase or system.

Due to the presence of the ordered liquid crystal surfactant phase, the composition of the present invention exhibits, upon visual inspection, an opaque appearance. The composition of the present invention exhibits an opaque appearance in the absence as well as in the presence of oil. As used herein, the term "opaque" means not completely transparent to light and is in a range from a translucent appearance through a cloudy appearance to a uniform, saturated, white appearance. In one embodiment, the structured surfactant system provides strips from a cloudy appearance to a uniform, saturated white appearance.

Due to the presence of the ordered liquid crystal surfactant phase, the composition of the present invention exhibits a yield strength of more than 0 Pascal. As used herein, "yield strength" refers to the magnitude of the applied force required to induce the composition to flow. In one embodiment, the composition exhibits a yield strength of more than 0 Pascal ("Pa"), more typically from about 1 to about 100 Pa, and even more typically from about 1 to about 100 Pa. about 10 Pa as determined by measurements using a controlled stress / stress rheometer at two or more shear rates. The presence of a non-zero yield strength can also be reliably determined on a qualitative basis by visually observing composition flow characteristics and composition strength caused by, for example, a motion of a hand spatula on a sample of the composition. In one embodiment, the surfactant system structured in the composition is capable of allowing the composition to suspend water-insoluble or partially water-soluble components such that the oil is preferably without the need to incorporate suspending agents. / thickening such that the polymers (typically polyacrylates) or EGDS. The ability to suspend such components can be observed as a manifestation of the presence of a nonzero yield strength. As used herein, the characterization of an aqueous composition as "capable of suspending" or as "capable of suspending" partially soluble or water-insoluble components means that the composition substantially resists the fluctuation of such components in the composition or the sinking of such components in such a composition such that such components appear to be neutrally floating in such a composition and remain at least substantially suspended in such composition under the conditions of processing, storage and anticipated use. for such an aqueous composition. The ability to suspend water-insoluble or partially water-insoluble components is a manifestation of the non-zero yield strength of the present invention, that is, the resistance of the structured surfactant composition of the present invention to deformation at low stress is sufficient. to balance the gravitational forces acting on the water-insoluble or partially water-soluble components such that the components remain suspended in the structured surfactant composition.

As discussed above, the ordered liquid crystal phase provides the composition with a rheology which is sufficient when the system is at rest to immobilize any suspended particles but, upon application of a shear force, is sufficiently low to allow the system to be pumped like a normal liquid. Such systems may exhibit very low apparent viscosities when agitated, pumped or dumped and yet are capable of holding particles, sometimes millimeters or larger, in suspension. In one embodiment, the structured surfactant system allows the composition to suspend air bubbles for at least 1 week, and more typically for at least 3 months. A composition which is capable of suspending air bubbles for at least 12 hours at room temperature is considered to be generally capable of suspending the water-insoluble or partially water-soluble components in the composition under the conditions processing, storage and anticipated use for such a composition. For components other than air, the result of the air suspension test shall be confirmed by conducting an analogous suspension test using the component of interest. For unusually stringent processing, storage and / or use conditions, stricter testing may be appropriate. In one embodiment, the ability to suspend water-insoluble or partially water-soluble components is assessed under more stringent conditions, ie mixed samples are visually assessed after samples undergo one or more freeze / thaw cycles. wherein each freeze / thaw cycle consists of 12 hours at -10 ° C and 12 hours at 25 ° C. In one embodiment, the structured surfactant system allows the composition to remain capable of suspending air bubbles after a freeze / thaw cycle, more typically after 3 freeze / thaw cycles.

In one embodiment, the composition of the present invention exhibits shear thinning viscosity. As used herein with reference to viscosity, the term "shear thinning" means that such viscosity decreases with an increase in shear rate. Shear thinning can be characterized by “non-Newtonian” behavior in that it differs from that of a classic Newtonian fluid, for example water, in which viscosity does not depend on the shear state.

Structured surfactant systems are known to those skilled in the art, and many have been described in the literature. In many cases, the structure is formed when some surfactants (including associations thereof) are associated with a structurant and / or an electrolyte. Structurants and / or electrolytes are known to those skilled in the art. In the present application they are considered, if present, as part of the structured surfactant system, as they typically participate in the formation of the structure, even if they are non-surfactant. In some cases, the structure is formed upon application of shear during the preparation of the composition and / or during the preparation of a premix use to produce the composition.

Some surfactant mixtures, which may participate in the formation of structured domains, are commercially available, with reference to the documentation associated with such property and / or use. Examples include Miracare® SLB grades sold by Rhodia.

Surprisingly, it has been found that the introduction of cationic co-surfactant may allow a structured form, while reducing the amount of electrolyte. It is thus possible to surprisingly decrease the amount of electrolyte such that NaCI, while adding some cationic co-surfactant, to a lesser amount than the amount of electrolyte subtracted. This may reduce the amount of salt in the composition, thereby reducing irritation and / or improving softness.

The ratio of the total amount of surfactant (s) to the electrolyte can also be adjusted so that the structured form is obtained.

The ability of the composition to suspend water-insoluble or partially water-soluble components is typically assessed by mixing the composition with sufficient vigor so that air bubbles are retained in the composition and then make a visual observation as to whether air bubbles remain in the composition for a defined period of time, such as, for example, 12 to 24 hours under defined environmental conditions, such as, for example, room temperature.

In the present patent application, the term "emulsion" particularly encompasses all these types of emulsion. Without wishing to be bound by any theory, it is specified that microemulsions are generally thermodynamically stable systems generally comprising large amounts of emulsifying agents. The other emulsions are generally systems in a non-thermodynamically stable state that retain for a certain period of time, in the metastable state, the mechanical energy provided during emulsification. These systems generally comprise smaller amounts of emulsifying agents.

Emulsions can be obtained by mixing the carrier, preferably an aqueous carrier, the polyorganosiloxane and generally an emulsifying agent, and then emulsifying. It is possible to speak of emulsification in situ.

In this embodiment, the composition preferably comprises a proportion of the emulsifying agent of more than 10 wt%, preferably at least 15 wt%, relative to the weight of the polyorganosiloxane.

The droplet size of the microemulsion may be measured or an emulsion may be prepared prior to its introduction into the cosmetic composition by dynamic light scattering (QELS), for example as described below. The equipment used is, for example, composed of a Spectra-Physics 2020 laser, a Brookhaven 2039 correlator and associated computing. As the sample is concentrated, it is diluted with deionized water and filtered through a 0.22 prn filter so that in the end it is 2% by weight. The obtained diameter is an apparent diameter. Measurements can be performed at 90Q and 135Q angles. For size measurements, in addition to conventional accumulator analysis, the autocorrelation function is performed in three ways (exponential sampling or EXPAM described by Pr. Pike, the non Negatively Constrained Least Squares or the NNLS method and CONTIN method described by Pr. Provencher), which each provide a size distribution weighted by light intensity rather than weight or number. The refractive index and water viscosity are taken into account.

Advantageously, the microemulsion is transparent. The microemulsion may, for example, exhibit a transmittance of at least 90%, preferably at least 95%, at a wavelength of 600 nm, measured for example using a Lambda 40 UV-Vis spectrometer at a concentration of 0.5% by weight in water. In this context, the cosmetic composition may advantageously be transparent.

Composition Preparation Process The composition may be prepared by any suitable process. Such processes are known to those skilled in the art. Typical processes involve mixing the different ingredients, optionally with premixing some of them and preparing material and / or pre-dispersion solutions or the like. Mixing may be performed at an appropriate shear rate. The application of some significant shear may be, in particular, useful for obtaining strained structured assets.

The structured surfactant composition can be produced, for example, by combining and mixing an anionic surfactant and water, adding a structuring agent, and then adding a liquid carrier such that water, and, optionally adjusting the pH and / or adding a preservative. Alternatively, a liquid carrier such as water may be added with the anionic surfactant and water. The structured surfactant composition may also be subjected to a high shear mixture. As used herein, the term "high shear mixing" refers to the mixing under high shear conditions, typically at a shear rate of more than or equal to about 1,000 s', more preferably less than about 1,000 seconds. typically greater than or equal to about 3,500 s 1. The oil may be mixed before or after shear mixing.

Process of Using the Make-up The make-up is typically used to treat hair. Hair treatment is typically performed by applying the compositions to the hair, preferably to damp hair. After application, the hair is usually rinsed. The hair treatment typically provides for the deposition of oil on the hair. With the composition of the invention, hair treatment improves hair treatment by depositing the oil on the hair.

According to a preferred embodiment, the treated hair comprises damaged hair, and optionally virgin hair. This mode covers the following situations: - part of the hair fiber is damaged (damaged part of the hair fiber) and part is not (virgin part of the hair fiber), and / or - some hair fibers are damaged. (damaged hair fibers) and some hair fibers are not (virgin hair fiber).

[00139] As used herein, virgin hair refers to undamaged hair. Hair damage can typically be observed by microscopy, preferably with a Scanning Electron Microscope.

Damaged hair typically presents with such an observation: - scales, typically erect scales, - porosity, - discoloration, and / or - split ends.

Damaged hair can also be characterized by hydrophilic properties, the contact angle being less than 90 ° C, for example.

Damage to hair may be the consequence of different causes, including chemical causes, physical causes, or other causes.

[00143] A common cause of damaged hair may be linked to how an individual regularly treats their hair, particularly if it makes use of harsh chemicals. Perms, relaxants, coloring treatments and bleaches can all be the contributing causes of damaged hair. Some of these chemicals cause the hair bristle cuticles to swell, which eventually leaves the hair with scales that are rough and fit and will break into shavings or fall together. Other chemicals, such as perms, relaxants, and bleaches are perhaps the most severe causes of damaged hair, as they destroy the bonds of hair protein, which weakens the inner structure of the bristles. Pollution can also be a cause of damaged hair.

Very tangled hair or the use of a rough comb or brush is perhaps one of the most common causes of damaged hair. Pillow covers, salt remaining on the hair after intense exercise or swimming, and hair accessories can also be the physical causes of damaged hair.

[00145] Sunrays and heat from hair styling instruments are common causes of damaged hair. Although the sun does not really affect healthy hair, chemically processed hair does not respond to UV rays. The sun is often one of the causes of damaged hair because it can cause hair proteins to shrink and weaken. When heated hair styling instruments, such as curling irons and blow dryers are used too often or over very hot styling, they can serve as causes of damaged hair.

[00146] The composition of the invention may allow the improvement of the damaged hair treatment / virgin hair treatment ratio.

[00147] The reason is typical of an improved selectivity of treatment to damaged hair, or a treatment that targets damaged hair. Selective and / or objective treatment may be emphasized in communication tools used by chemical ingredient suppliers of shampoo compositions, for example in animations or in films, presentations, flyers, flyers, posters, technical data leaflets, forms, or on any media, including papers and websites. This may be related to a complete or semi-complete composition, or to a particular product used to prepare a composition, for example a product that provides a structured surfactant system and / or a cationic co-surfactant and / or to an oil. Selective and / or targeted treatment can likewise be emphasized in communication tools used in commercial shampoo compositions on any medium, including newspapers, labels, websites, movies or animation. Examples of commercial claims may include selective or objective deposition, selective or objective treatment, selective or objective hair repair, or the like. Films or animation may, for example, have a hair fiber (or a representation thereof) having damaged parts (e.g. split ends or scales) and a product (or a representation thereof) approaching the hair fiber. and treat the damaged part while the virgin part is substantially ignored.

[00148] The composition may allow better objectification of damaged hair. For example, it can provide increased oil deposition where it is most required, for example on the extreme and tip regions. Improved selectivity for damaged hair can prevent the disadvantages of intensive and repeated deposition where not needed, such as the cumulative effect and / or perception of fatty hair, typically at the root, or perception of Heavy hair or dull hair.

The composition according to the invention can provide various treatment benefits such as styling, spreadability, rinse ability, after-rinse skin feel, and the combability of damp hair, the feel wet hair, the combatability of dry hair and / or the feel of dry hair.

EXAMPLES

Example 1: Shampoos having a structured surfactant system and silicone oil - Effect of cationic surfactant on viscosity.

The two structural formulations are prepared (identified as "structured -A" and "structured -B"). The formulations comprise: - a structured surfactant system based on the Miracare® SLB365 (Rhodia) surfactant mixture having sodium trideceth sulfate, lauro anfoacetate disodium and cocamide MEA (approximately 50% surfactant by weight), - a Conditioning: Jaguar® C17 (Rhodia) - A micronic silicone emulsion: Mirasil® DME-2 (Rhodia) (50% silicone by weight).

The formulation "Structured -A" is a comparative formulation, which corresponds to a formulation free of cationic surfactant.

The "Structured-B" formulation is a formulation comprising cetrimonium chloride ("CTAC"), cationic surfactant: Incroquat® CTC-30 (Croda) (39% CTAC by weight).

Both formulations are detailed in Table 1 below (amounts are amounts in% by weight, "as if" as opposed to quantities of active substance).

Table 1: The procedure for preparing 100 g of Structured A and Structured B formulations is as follows: - mix the required amount of deionized water together with Jaguar C17, such that the final polymer concentration is the same (0.35% by weight) as that of the SSL shampoo formulations of Table 1; adjusting the pH of the solution to the required amount of Versene 100 (EDTA); adding the required amount of Miracare SLB365 such that the final concentration of the mixture is 45% by weight in the formulation; -add the required amount of sodium chloride solution (20% NaCl by weight) such that the final salt concentration in NaCl is in the range 2.0 to 3.5% by weight. weight, in the formulation, depending on whether or not Incroquat CTC-30 has been added; -add 0.5 g of the preservative sodium benzoate; adjust the pH of the solution to pH = 6 to 6,5 with a concentrated citric acid solution (50% citric acid by weight).

[00156] Evaluation [00157] The viscosity of both formulations is measured at room temperature after a 24 hour rest period using a Brookfield rheometer (RV4 spindle, viscosity taken at 10 rpm). Viscosity is reported in Table 1. The formulation "Structured B" has a higher viscosity with a substantially lower amount of salt. The cationic surfactant can thus be used in a structured surfactant system in order to reduce the amount of salt and thereby reduce the potential irritation capability.

Comparative Example 2: Shampoos having micellar-shaped surfactants and a silicone oil [00159] As reference comparative examples, the following four micellar formulations "micellar A", "micellar B", "micellar C", "micellar" D ”) are prepared. The formulations comprise: - sodium lauryl sulfate ("SLES"), Empicol® ESB3 / M (Huntsman) (27.2% SLES by weight); - cocamidopropyl betaine (“CAPB”), Mirataina® BETC30 (Rhodia) (30% by weight of CAPB); - a conditioning polymer: Jaguar® C17 (Rhodia); - various silicone emulsions: - one micron silicone emulsion: Mirasil® DME-0.6 (Rhodia) (65% by weight silicone) - in some shampoos: cetrimonium chloride (“CTAC”), cationic active stress: Incroquat ® CTC-30 (Croda) (30% by weight of CTAC).

The formulations are detailed in Table 2 below (amounts are amounts by weight% 'as such' as opposed to quantities as active material).

The procedure for preparing 100 g of formulation is as follows: - mix the required amount of deionized water together with Jaguar G17, such that the final polymer concentration is the same (0.35 % by weight) than that in the SSL shampoo formulations of Table 1; adjusting the pH of the solution to pH = 4 to 5 with the required amount of a concentrated solution (50% by weight) of citric acid; adding the required amount of M ratai into METC30 such that the final concentration of CAPB is 2% by weight in the formulation; adding the required amount of Empicol ESB3 / M such that the final SLES concentration is 14% by weight of the formulation; adding the required amount of Incroquat CTC-30 such that the final CTAC concentration is 0 or 0.9% by weight of the formulation; add 0.1 g of the preservative Kathon CG; adjusting the pH of the solution to a pH of 6 to 6.5; adding sodium chloride (NaCl) such that the final salt concentration is 1.6% by weight in the formulation; Add the required amount of Mirasil DME-0.6 or Mirasil DME-2, such that the final concentration of silicone oil is 3% by weight (solids) in the formulation.

The micellar shampoos C and D of Comparative Example 2 are based on the same silicone oil emulsion (Mirasil® DME-2) and can be directly compared to structured shampoos A and B of Example 1.

Example 3: Assessment of Silicone Oil Deposition on Virgin & Damaged Hair and Selectivity Assessment The assessment involves the micellar and structured shampoos listed in Tables 1 and 2, containing either 0 or 3% Incroquat CTC. -30 in the final formulation and in all cases 3% by weight of silicone oil from two types of silicone emulsions, either submicron (DME 0, 6) or micron (DME 2).

Silicone oil deposition is evaluated on virgin hair as well as on damaged hair with each formulation by washing using 10 grams of hair with a 1 gram shampoo dose. The silicone oil deposited on the hair is extracted with tetrahydrofuran (THF) and the deposition yield is measured with gas chromatography. Results are provided in Table 3 below.

From the amounts deposited, one can define the selectivity of deposition by considering the ratio of the amount of silicone deposited on damaged hair to that deposited on virgin hair: Selectivity = amount deposited on damaged hair Equation 1 amount deposited on virgin hair Table 3: Shampoo Reference / VIRGIN HAIR / DAMAGED HAIR / Shampoo Reference Virgin hair Damaged hair yield ppm yield silicone silicon deposition pg / g deposition pg / g hair selectivity (%) ( %) Hair Micellar Shampoo A „af 56.3” 6.7% 19637ÍW 5.2,3% 15? ± S $ 00 „(comparative) 0.08AO19 Micellar Shampoo B 37.5 0-4% 1306 9 1 , 7-0.5% 51 4 (comparative) 0.04 0.005 Micellar shampoo C, 01, n ..., 17 14.3α% 490 0 1JA6% 50 7 (comparative) 0.10 ■ Structured shampoo D 7, 9.10 · 1% 273.13 1.5: M% 45106 (comparative) 0.16 0.043 Structured shampoo A 14.111.6% 527443 3.3: 1J% 100437 (comparative) 0.19 * 0.045 XamP ° 29, 740.0% 938 + 3e 11.9t, J% 354+ "Structured B 0.38-0.032 [00167] With reference to deposition: [00168] Regardless of the amount of silicone oil, the yield of micellar shampoo deposition fails how much CTAC cationic surfactant is added, and this is true of both virgin and damaged hair. For example, in the case of the finer sub-chronic emulsion Mirasil® DME-0.6, it is found that: - In virgin hair, the silicone deposition is 19634 208 ppm with micellar shampoo A and 1306-199 with micellar shampoo. B, which also contains CTAC, implying a - 33% reduction in the deposited amount of the Mirasil® DME - 0.6 submicron silicone emulsion; - In damaged hair, silicone deposition is 157 ± 56 with micellar A shampoo and 51 ± u ppm with Micellar B shampoo, which also contains CTAC, resulting in a -68% reduction in the amount of submicron emulsion deposited. thinner Mirasil® DME - 0.6.

Similar failures in silicone oil deposition are found with micron silicon oil Mirasil DME-2 in micellar shampoos added with the CTAC cationic surfactant.

In contrast, the addition of CTAC cationic surfactant to structured shampoos improves the efficiency of silicone oil deposition on both hair types: - In virgin hair, silicone deposition is 527 ± 49 ppm with Structured shampoo. A and 938 ± 36 ppm with Structured B shampoo, which also contains CTAC, implying a + 78% increase in the amount of silicone oil deposited; - In damaged hair, silicone deposition is 100 ± 37 ppm with Structured A shampoo and 354 ± 47 ppm with Structured B shampoo, which also contains CTAC, resulting in a + 72% increase in the amount of oil deposited. Silicone

In all cases, the amounts deposited are much greater than those achieved by Micellar S and C shampoos, which are based on the same silicone oil (Mirasil DME-2).

With reference to selectivity: The selectivity of micellar shampoos is poor, whether or not the CTAC cationic surfactant is added, and regardless of the size of the silicone emulsion; micellar shampoos in all cases achieve a deposition ratio of about 0.1 to damaged virgin hair (see Table 3): effective selectivity values are in the range of 0.04 ± 0005 for shampoo Micellar B to 0.16 ± 0.049 for Micellar S shampoo. In other words, micellar shampoos deposit about 10 times less silicone on damaged hair than virgin hair.

The selectivity of structured shampoos is much higher: Structured shampoo A has a selectivity of 0.19 ± 0045, while Structured Shampoo B, which contains 0.9% by weight of the CTAC cationic surfactant, has a selectivity twice as large, at 0.38 ± 0.032. Thus, the presence of cationic surfactant in a structured shampoo enhances selectivity.

This allows significant treatment of damaged parts of the hair, while avoiding overtreatment of virgin parts of the hair and can reduce the accumulation of negative effects.

Example 4: Sensory Performance Assessment (consumer test) [00177] Structured shampoo A (comparative, CTAC free, see Table 1) and structured shampoo B (comprising CTAC, see Table 1) are evaluated by an independent specialized institute (Institut Dr. Schrader - Creachem GmbH- Max-Planck- Strasse 6 - 37603 Holzminden).

According to this assessment, half-head tests are performed on 10 volunteers with medium-long dry / damaged hair: Shampoo A is applied (according to a standard hair-cleaning procedure-shampoo application 1) over one side of the hair and shampoo B is applied over the other side of the head. The application is performed by a trained expert. The two shampoos are directly compared by an expert in terms of: (1) pullout property, (2) spreadability, (3) time to form the foam, (4) amount of foam, (5) texture of the foam. foam, (6) skin sensitivity to foam, (7) rinsing ability, (8) skin sensitivity after rinsing, (9) wet hair combatability, (10) wet hair sensitivity, (11) dry hair combatability , (12) Sensitivity of dry hair. Results are reported in Figure 1.
