Definitions
- the invention relates to a brush with germicidal properties for applying a mascara.
- a mascara is a cosmetic product used to color and / or thicken eyelashes.
- This composition is applied to the eyelashes by means of a brush traditionally attached to the stopper sealing the bottle containing the composition in question.
- the successive applications of the mascara using this brush on the one hand, and the reintroduction of said brush into the bottle containing the mascara itself on the other hand therefore induces a risk of contamination.
- said cosmetic composition with germs, and in particular bacteria or fungi (germs removed by the brush in contact with the user's skin or eyelashes).
- preservatives that is to say of additives capable of avoiding and at the very least limiting the development of these germs .
- preservatives are irritants and capable of causing reactions of the eye, very close to the deposit zone of said mascara.
- use of such preservatives can induce the creation of resistant bacterial strains capable of developing in the eye, with the pathological consequences likely to ensue therefrom.
- the object of the present invention aims on the one hand, to allow the increase in the duration of use of the mascara application brush, therefore to optimize the expiration date of such a product. It also aims to (minimize the amount of preservatives incorporated into said cosmetic composition, by avoiding as much as possible the release of the germicide in the mascara.
- the expression “large anion” denotes an anion chosen from the group comprising: - anions of the carboxylate (for example oleate) or alkylsulfate (for example laurylsulfate) type having an alkyl chain having a number of carbons greater than 10; - or polyanions of the polycarboxylate type (for example polyacrylate); - or other anions of the silicate, polyphosphate type.
- the expression “large cation” denotes a cation chosen from the group comprising: - quaternary ammoniums carrying at least one alkyl chain having a number of carbons greater than 8, - canonical polymers of the ammonium polyacrylate type, - polyiminium hydrochlorides and in particular polyhexamethylene-biguamide (PHMB), - polymers carrying quaternary ammonium functions and in particular quaternary polyammoniums.
- PHMB polyhexamethylene-biguamide
- the invention provides a brush for applying a mascara consisting of polymer bristles coated with a germicidal composition produced from a mixture based on: - at least one large cation and at least one large anion, either or both of which develop germicidal properties.
- a germicidal composition produced from a mixture based on: - at least one large cation and at least one large anion, either or both of which develop germicidal properties.
- This particular mixture thus allows a fixing of a compound with germicidal properties on the bristles of the brush, whose experience shows that there is no salting out in the mascara.
- this compound makes it possible to develop germicidal properties in a satisfactory manner and in any case in accordance with the aim sought by the present invention.
- the constituent polymer of the bristles of the brush is a polyamide and in particular a polyamide 6.12.
- a synthetic polymer chosen from the group comprising polyurethane, polyethylene, polypropylene, polyester, polyacrylic, modacrylic, alone or as a mixture.
- the constituent polymer of the bristles of the brush can also be an artificial or natural polymer.
- the cation used comes from a salt (for example hydrochloride) of polyiminium, and in particular of polyhexamethylene biguanide, more commonly called PHMB.
- This cation can also consist of a quaternary ammonium salt, in particular a quaternary polyammonium.
- the large anion results from a salt of sodium polyacrylate, sodium silicate, sodium polyphosphate, sodium oleate or sodium lauryl sulfate.
- the Applicant has found that particularly advantageous results are obtained in terms of germicidal properties and absence of salting out in mascara, when the composition of the invention combined sodium oleate and PHMB, advantageously in proportions of 50/50 in mole.
- the invention also relates to the process for depositing such a germicidal composition on the brushes for applying a mascara.
- This process consists of: to carry out a cold soaking of the brush in a mixture of at least one large cation salt and at least one large anion salt, one or the other or both having germicidal properties; - then carry out a rinsing step in order to remove the excess product, which is not attached to the brush bristles, - then carry out a drying step in order to remove the water contained in the brushes.
- the anion and cation salts can be mixed successively, one before the other and vice versa.
- FIGs 1 and 2 represent an illustrative graph of the germicidal action of the composition of the invention with respect to Escherichia coli CD? 53.126 under normal conditions of use.
- FIG. 3 represents an illustrative graph of the germicidal action of the composition of the invention with respect to Staphylococcus aureus CD? 4.83 under normal conditions of use.
- Example 1 Preparation of brushes with germicidal properties 5300 brushes, produced from 6.12 polyamide bristles of 80 micrometers in diameter (representing a weight of 1500 grams) are placed in a 10 liters and are treated as follows: - Prepare 4, 5 kg of a sodium oleate solution at 0.69% by weight: dissolve 31.05 g of pure sodium oleate in approximately 500 ml of lukewarm fresh water; make up to 4.5 kg with cold fresh water. - Prepare 4.5 kg of a Cosmocil CQ solution (PHMB marketed by Avecia at 20% by weight in water) at 0.5% by weight: dissolve 112.5 g of Cosmocil
- This example aims to test the germicidal properties of the composition of the invention when it is applied according to the method of Example 1 on different types of fibers constituting a mascara brush.
- composition of the invention is applied to three different types of brush, respectively: 1. polyamide 6.12 2. polyamide 6.6 3. polyamide 6 (two origins)
- each brush sample is immersed in the COSMOCIL CQ / SODIUM OLEATE formulation with stirring for several hours at ordinary temperature.
- the bath ratio: Hquide mass / Brush mass is 3 to 10 (more advantageously: 6).
- the brushes are rinsed, wrung out and then dried.
- the brushes treated are, depending on the case, post-treated by rinsing with cold fresh water, or not.
- a change in contamination is measured every day for bacteria for one week and at times D + 1, D + 5 and D + 7 for yeasts and molds. The values are given in CFU / ml. Each test is carried out in triplicate. The results are shown in Tables 2 to 6 below.
- samples A2, B2, C2 and D2 exhibit good anti-bacterial and anti-fungal activity. There is indeed a rapid decrease: count less than 2 CFU / ml in 24 hours.
- samples A2 and D2 show good anti-bacterial activity since a rapid decrease is observed, a threshold below 2 CFU in 24 hours.
- samples B2 and C2 show good anti-bacterial activity in 6 days since the decrease results in a threshold below 2 CFU / ml.
- This measure of release in the mascara is carried out under normal conditions of use, that is to say at the level of the actual cosmetic composition contained in the bottle. It consisted in measuring or detecting the bactericidal COSMOCIL® material fixed according to the method described above on the bristles of the brush.
- the brushes are contacted for 8 days at room temperature and 40 ° C continuously.
- Negative controls and COSMOCD ® (20 ° solution) are used to calibrate the measuring equipment used.
- Example 3 Measurement of the Antimicrobial Activity of the PURCILON® Fibers Mounted in a Brush Under Real Conditions of Use
- the antimicrobial activity of fibers treated with PURCILON® mounted in a brush is verified under real conditions of use, that is to say with respect to the mascara.
- Composition of PURCILON Polyamide 6.12 at 4.7% in dry matter content (close to the reference A2R) treated according to the process described above, on 1000 brushes.
- MATERIAL AND METHOD Base mascara The basic formula chosen is a black resistant water mascara with the following preservative system:
- This database also contains materials that can facilitate the activity of preservatives such as:
- the strains are maintained by cryo-freezing. They are used after subculturing on Trypcase soy agar. EXPERIMENTAL PROTOCOL witnesseses and tests carried out The tests carried out with treated fibers and mascara with preservative are called Ft tests.
- - Ta treated fibers, uncontaminated brought into contact with mascara without preservative, which makes it possible to check the cleanliness of the treated fibers as well as that of the bottles.
- - Tb untreated, uncontaminated fibers brought into contact with preservative-free mascara, which makes it possible to check the cleanliness of the untreated fibers as well as that of the bottles.
- - Te treated, contaminated fibers brought into contact with preservative-free mascara, which makes it possible to verify the real incidence of the bactericidal effect of the treated fibers.
- - Td untreated, contaminated fibers brought into contact with mascara containing preservatives, which makes it possible to verify the impact of the preservative system of mascara on the reduction in the concentration of germs.
- - Te untreated, contaminated fibers brought into contact with mascara without preservatives.
- the principle consists in contaminating the brushes by soaking in a solution of germs and then introducing them into mascara bottles containing 6 grams of the Cilpur® formula and monitoring the course of contamination over time.
- the protective power of the fibers was studied using: - two stock solutions of E. coli calibrated so as to obtain an initial contamination of the order of 10 8 CFU / ml for SI and 10 7 CFU / ml for S2. - a stock solution of S. aureus calibrated so as to obtain an initial contamination of the order of 10 5 CFU / ml. So as to assess the initial quantity of germs, using the brush, recover: - for E. coli 0.5 g ⁇ 0.05 g of mascara in 9 ml of Eugon LT100 (neutralizing diluent), - for S.
- Controls carried out on S. aureus The vials are checked after 1.2 and 6 hours of contact time for the first two contaminations. For the third over-contamination, the controls are carried out after 1, 2, 6 h and 24 h of contact.
- Staphylococcus aureus As for E. coli, there is a strong decrease in germs for the Td and Ft tests ( Figure 3). Comparison with the results obtained for the tests
- Te and Te allow us to determine that this reduction in log is directly linked to the joint action of the preservatives present in the mascara and the germicide present on the treated fibers.
