Definitions
- the subject of the invention is a process for modifying the surface of a pigment or a composite pigment comprising at least one metal oxide, a metal complex or one of their derivatives, and the use of these pigments or composite pigments thus obtained. for cosmetics, paint or inks.
- Inorganic pigments can be used for their coloring power in cosmetics, but also in paints and inks. These pigments are required to be able to disperse homogeneously with the desired color rendition and while having good stability when formulated for these different fields of use.
- inorganic pigments such as metal oxides or composite inorganic pigments comprising them, naturally tend to aggregate because of their size, their high density and their natural affinity, especially when trying to disperse them in solvents " green "(non-toxic).
- pigments tend to aggregate also when they are stored in powder form before their formulation and their end use, which makes it difficult to store and preserve in raw form after production.
- the inventors have demonstrated a new method for modifying the surface of a substrate, in particular a pigment intended to give this substrate interesting properties, especially in the field of cosmetics.
- This method consists in grafting, in one or more steps, on the surface of the substrate, groups bringing a new surface functionality to the substrate and thus modifying its properties.
- This process is characterized by chemical grafting via a coupling agent.
- the invention also relates to the substrate obtained by this method as well as the various applications of the functionalized substrate.
- the coupling agent is attached to the substrate (grafting) by reacting one of its functions with the surface of said substrate by forming a stable covalent or ionocovalent bond.
- the method makes it possible to treat with the same coupling agent a large variety of substrates (metals, alloys, metal oxides, etc.);
- This method allows the deposition of coupling agent in the form of monolayers, thus minimizing the amount of coupling agent required and avoiding the masking of the terminal functions. Indeed, the accessibility of the terminal functions on the surface depend on the effectiveness of the properties conferred on the substrate;
- the grafting process is carried out under conditions that are easier than those of the prior art, for example under ambient, non-anhydrous conditions, which makes it possible to avoid the use of organic solvents.
- the invention relates to a method of modifying substrates (inorganic pigments, composite pigments) to confer interesting properties in the field of cosmetics, paint or inks.
- the method comprises grafting in one or more steps on the surface of the substrate groups having properties for applications in the field of cosmetics, paint or inks.
- the coupling agent is grafted onto the surface of the substrate by immersing the substrate in a solution containing the coupling agent.
- the functionalized substrate is then extracted from the grafting solution and dried.

- the grafting step is carried out by chemical reaction between a coupling agent of desired concentration and the surface of a pigment to be modified, in the chosen solvent (EtOH, H 2 O or H 2 O / EtOH mixture) for a time. longed for.
- a coupling agent solution is prepared by dissolving the coupling agent in 10 ml of solvent.
- the concentration of the solution varies between 10 "1 and 10 " 3 mol.l 1 depending on the torque (selected Coupling Agent / Substrate to be treated).
- the choice of the solvent H 2 0, EtOH or H 2 O / EtOH mixture also varies depending on the Coupling Agent / Substrate pair.
- Conventional organic solvents can also be used, but current environmental considerations tend to diminish their use.
- Static Condition The chemical reaction occurs without magnetic stirring at room temperature (10-35 ° C) for a time t.
- the grafting solution is removed by filtration and the material (modified substrate) is washed to ensure the complete removal of all physisorbed elements.
- the filtrate is removed from the centrifuge tube.
- the centrifuge tube is refilled at 3 ⁇ 4 with EtOH and placed in an ultrasonic tank for 10 minutes.
- the functionalized pigment powders (substrates) are transferred to a glass pill and dried for 12 hours.
- the temperature of the oven varies between 20 and 150 ° C depending on the tolerance of different substrates to the thermal conditions.
- the substrate to be treated may be a pigment of mineral origin, a metal oxide or a metal complex usually used in cosmetics, paint or inks. These are porous or non-porous solids which are in the form of powder, a non-exhaustive list of which is presented below:
- the coupling agent is an organophosphorus derivative, it may be chosen from phosphomic acids, monoesters and diesters of phosphonic acid or their derivatives, phosphoric acids, monoesters and diesters of phosphoric acid or their derivatives.

- the organophosphorus derivatives can be attached to a very large number of metal oxides such as iron oxide, titanium dioxide, chromium oxide, etc. Only MOP bonds are involved during grafting on the substrate. These bonds are more stable than the MO-Si bonds created with an organosilane coupling agent (state of the art: prior art search).
- the invention also relates to a modified inorganic substrate obtained by the process.
- the substrate has a surface to which are bonded organophosphorus groups which may have one or more organic substituents at the origin of the properties provided to the substrate.
- the field of cosmetics employs a large number of inorganic pigments.
- this sector seeks to give these pigments a hydrophobic character.
- the carbon chain of phosphonic acids of formula R-PO (OH) 2 confers the desired hydrophobic character.
- the hydrophobic nature in other words the effectiveness of the grafting, has been qualified thanks to hydrophobicity and dispersion tests in the oil.
- the pigments used in cosmetics which require hydrophobic surface functionalization are polar in nature. Once functionalized, they become apolar and therefore have an affinity with fatty substances (also apolar). In contrast, there is a repulsion with polar binders such as water.
- the hydrophobicity test makes it possible to study the impregnation of the porous materials with water when they come into contact.
- 0.1 g of substrate functionalized on the surface of about 100 ml of osmosis water at 40 ° C and after having left the rest in an oven during 1 h at 40 ° C the passage or not of the functionalized substrate in the aqueous phase reflects its hydrophobic character.
- the oil dispersion test indicates the adsorption performance of oil in cosmetics.
- the reduction of the amount of oil incorporated to obtain the complete wetting of the functionalized substrate with respect to that required for an untreated substrate reveals its hydrophobicity.
- 2 g of substrate, previously deposited in a watch glass are mixed with a spatula for 3 to 4 minutes to the oil deposited dropwise with a burette.
- the diffuse reflection UV / visible spectrophotometry then makes it possible to verify that the grafting process did not alter the color of the pigment intrinsically.
- hydrophilic character of the pigments Another example of properties of interest to the cosmetics sector is the hydrophilic character of the pigments.
- the studies carried out show that the pigments treated with a coupling agent such as (2- ⁇ 2- [2- (2-hydroxyethoxy) -ethoxy] -ethoxy ⁇ -ethyl) phosphonic acid have a hydrophilic character.
- Example 6 Example of embodiment
- Example 7 Organic Pigments
