Definitions
- the invention relates to the field of cosmetic or dermatological formulations for topical application, comprising an aqueous phase and an oily phase, said aqueous phase being gelled by a carboxyalkylated starch.
- carboxymethyl starch Used as thickening agents or gelling agents in aqueous gels or emulsions, in particular oil-in-water, carboxymethyl starch advantageously makes it possible to obtain a cosmetic or dermatological composition giving a sensation known as a “cushion effect” when applied to the skin.
- carboxymethyl starch can at the same time cause a phenomenon known as “linting”, which consists of the formation of “fluff”, or “pills”, on the skin, which prevents a uniform and pleasant application, or even causes a very unpleasant sensation.
- This fluffing may occur both during the application of said compositions to the skin, i.e. when spreading on the skin using the fingers of the hand, but also after application, when the composition has penetrated the skin and the skin is subjected to friction, either skin against skin or skin against clothing. In both cases, the fluffing must be reduced to a minimum so that no residue remains on the skin.
- the present application provides a solution for reducing linting during topical application or after drying, or during topical application and after drying, of a cosmetic or dermatological composition comprising a carboxyalkylated starch, in particular carboxymethylated, while maintaining a significant and pleasant cushion effect.

- This embodiment makes it possible to achieve a cushion effect ranging from 6.25 to 8.25 together with a fluffing on application of less than or equal to 4.75 and a fluffing after drying of less than or equal to 3.0.
- the surfactant is chosen from sodium stearoyl glutamate, caprylyl/capryl glucoside, polyoxyethylene sorbitan monolaurate, or polyoxyethylene sorbitan monooleate.
- This embodiment makes it possible to achieve a cushion effect ranging from 6.25 to 8.25 together with a fluffing on application of less than or equal to 3.75 and a fluffing after drying of less than or equal to 1.75.
- the cosmetic or dermatological composition that is the subject of the present application has the advantage of having a sensory profile characterized by a significant cushion effect and by moderate fluffing upon application and/or after drying.
- significant cushion effect is meant a cushion effect, measured according to the sensory evaluation method described in the present application, having a score greater than or equal to 5, preferably greater than or equal to 6, greater than or equal to 7, and most preferably greater than or equal to 7.5.
- moderate fluffing upon application and “moderate fluffing after drying” is meant fluffiness measured according to the sensory evaluation method described in the present application, having a score less than or equal to 5, preferably less than or equal to 4, preferably less than or equal to 3.
- wet fluff When applying the cosmetic or dermatological composition, two types of residues may form: wet fluff and/or a film of wet material, which may persist on the skin after application.
- film of wet material is meant the layer of cosmetic or dermatological composition that has not penetrated the skin, and therefore spread on the skin more or less homogeneously, and with a thickness of less than approximately 1 mm, preferably less than or equal to approximately 0.5 mm.
- wet fluff fragments of cosmetic or dermatological composition having a consistency sufficient to be individually visible and felt to the touch, which may be similar to aggregates or agglomerates of the constituents of said composition, and which still have a high water content.
- sand-type residue is meant more or less dry fragments, of a size less than 1 mm, which can be similar to small scales or to fine to very fine sand, and which are felt when rubbing on the skin as a slight exfoliating sensation.
- dry fluff is meant low-water aggregates in the form of individualized and well-formed “pills”, containing all or part of the constituents of the cosmetic or dermatological composition. This dry fluff can be in the form of “sausages” of a length greater than or equal to 2 mm and a width greater than or equal to 0.5 mm.
- the cosmetic or dermatological composition has:
- Another subject of the present application is the use of an oil and a surfactant for in a cosmetic or dermatological composition comprising at least one carboxyalkylated starch as a thickening agent for the aqueous phase of said composition, said use being characterized in that the ratio of the mass of the oil to the mass of the surfactant is in a range from 0.3 to 7, or from 0.5 to 6, or from 0.75 to 5, or from 1 to 4, or from 1.25 to 3, or from 1.5 to 2.5, or is equal to 2, and said use making it possible to reduce or eliminate fluffing on application and/or after drying, while maintaining a cushion effect.
- this use consists of the use of a non-volatile polar hydrocarbon oil of vegetable or plant origin and a non-ionic surfactant.
- the non-volatile polar hydrocarbon oil of vegetable origin may be chosen from vegetable oils rich in monounsaturated fatty acids, macadamia oil, for example macadamia oil.
- the non-ionic surfactant may be chosen from sorbitan esters, polyglyceryl fatty acids, citric acid diesters, or mixtures thereof, for example the mixture of sorbitan laurate, polyglyceryl-4 laurate and di lauryl citrate, for example that marketed under the reference “Tego® Care LTP” by the company Evonik Personal Care.
- the gelling or thickening system with a cushioning and moderate fluffing effect comprises, preferably consists of:
- carboxyalkylated starch preferably chosen from carboxyethylated starches, carboxymethylated starches, carboxypropylated starches, carboxybutylated starches, and most preferably the carboxyalkylated starch is a carboxymethylated starch,
- oils of natural origin in particular vegetable oils, and mineral oils, silicones
- oily phase consists of at least one oil of natural origin, in particular vegetable oil
- At least one surfactant preferably chosen from nonionic surfactants or cationic surfactants.
- the ratio of the mass of the oil to the mass of the surfactant is within a range from 0.3 to 7, or from 0.5 to 6, or from 0.75 to 5, or from 1 to 4, or from 1.25 to 3, or from 1.5 to 2.5, or is equal to 2.
- the sensory profile of a cosmetic or dermatological composition according to the subject of the present application is evaluated by a panel of at least four people who are experts in the sensory analysis of cosmetic products, trained for four months, at a rate of one session per week, to evaluate the following three sensory criteria according to a scale ranging from 0 to 10: the cushion effect, the fluffing on application, and the fluffing after drying.
- the “0” limit of the scale of a sensory criterion corresponds to the minimum value of said criterion, i.e. the weakest sensation for this criterion
- the “10” limit corresponds to the maximum value of said criterion, i.e. the strongest sensation for this criterion.
- the training of the panelists consists of sensory memorization, that is to say the memorization of the sensations felt, when taking in hand and applying to their forearm reference compositions corresponding to the extreme limits of the ranges of the criteria to be evaluated, namely: [0190] for the “0” terminal of the three criteria evaluated here: the “fluid” terminal of the “EBITouch®” kit for the “cushion effect” criterion, and the bare skin of the inner area of the forearm, presenting very little or no hairiness, for the fluffing on application and the fluffing after drying.
- the “cushion effect” criterion it is evaluated when approximately 0.04 grams of reference composition or composition to be evaluated are taken in hand, the composition is placed between the index finger and the thumb, then three pressures are exerted by spreading the fingers no more than 0.5 cm apart.
- the “10” limit is described as giving a “rebound” effect, and corresponding to a very elastic composition that retains its consistency.
- the “0” limit is described as giving no rebound effect, and corresponding to a composition that is not at all elastic, and that is fluid, that is to say that spreads without retaining its consistency.
- the criterion “linting on application” it is evaluated when applying approximately 0.2 grams of composition to the inside of the forearm.
- the composition is taken with the index finger and then applied to a rectangular area called “measuring”, located on the inside of the forearm, with dimensions of approximately 7 cm in the longitudinal direction, and approximately 5 cm in the transverse direction, by performing ten rotations with the tip of the index finger, covering the entire surface and at a speed of approximately one revolution per second.
- the “10” limit is described as forming a large quantity of wet lint.
- the rating “4” corresponds to the maximum quantity of “wet material film” type residue persisting on the surface of the skin after application.
- the “0” limit corresponds to the total absence of wet lint and “wet film” type residue.
- the “linting after drying” criterion it is evaluated seven minutes after the evaluation of the “linting on application” criterion on the same rectangular area “as is”, i.e. in the state in which it is found the evaluation of the “linting on application” criterion, i.e. after the application of approximately 0.2 grams of composition on the forearm according to the protocol for the “linting on application” criterion.
- the seven-minute waiting time must allow the penetration and/or drying of the composition that may have persisted in the form of a film of wet material and/or wet lint at the end of the application step.
- the “0” limit corresponds to the total absence of “sand” type residue and dry fluff.
- the “4” rating corresponds to a maximum quantity of “sand” type residue.
- the “6” rating corresponds to the appearance of the first dry fluff, which is generally concomitant with the disappearance of the “sand” type residue, a priori due to its transformation into dry fluff.
- the “10” limit is described as forming a large quantity of dry fluff.
- Example 1 Reduction of linting of an aqueous gel of carboxymethylated starch by addition of macadamia oil and Teqo® Care LTP
- the aqueous gel of BBR ST 118 has an already low rating, with a value of 1.6.
- the combination macadamia oil and Tego Care LTP also induces an increase in fluffing upon application, but to a lesser extent, so that a rating of around 3 or 4 is achievable.
- Tego Care LTP allows a reduction in the fluffing after drying, significant from a Tego Care LTP content of at least 3% by weight, to reach ratings lower than approximately 6.
- the combination of macadamia oil and Tego Care LTP allows a very significant reduction in the fluffing after drying.
- the present example therefore shows that the combination of macadamia oil and the non-ionic surfactant Tego Care LTP makes it possible to reduce fluffing after drying, while maintaining the fluffiness on application and the cushion effect at acceptable ratings.
- aqueous gels comprising from 6 to 8% by weight of BBR ST 118 carboxymethylated starch are evaluated, to which a binary combination of the nonionic surfactant Tego Care LTP and an oil selected from the oils in Table 7-1 is added. Initially, the surfactant content is set at 2.5% by weight, and that of the oil at 5% by weight, relative to the total weight of an aqueous gel containing 7% by weight of BBR ST 118. [Table 7-1] [0215] Each gel was then subjected to a sensory evaluation by the trained panel on the criteria of cushion effect, fluffing on application, and fluffing after drying. The results of these sensory evaluations which were carried out are presented in Table 7-2. [0216] [Table 7-2]
- Example 3 combinations of Macadamia oil with other surfactants
- aqueous gels comprising from 6 to 8% by weight of carboxymethylated starch BBR ST 118 are evaluated, in which a binary combination of macadamia oil and a surfactant selected from the surfactants in Table 8-1 is added. Initially, the surfactant content is set at 2.5% by weight, and that of the oil at 5% by weight, relative to the total weight of the aqueous gel at 7% by weight of BBR ST 118.
- the surfactants from the first line (surfactant T19) to the thirteenth line (surfactant T5) all make it possible to achieve a cushion effect greater than or equal to 6.3 and a fluffing on application of less than 5.0. These same surfactants jointly make it possible to achieve a fluffing after drying of less than or equal to 4.0.
- the surfactants from the fourteenth line (surfactant T16) to the nineteenth line (surfactant T13) give a fluffing on application greater than 5, or even 7, and/or a fluffing after drying greater than 6.
