Definitions
- the invention relates to a method for reducing the drying properties of a soap based on fatty acid salts. It extends to the new cleaning compositions prepared by implementing this process.
- fatty acid-based toilet soaps have the defect of having a strong drying power for the skin. This defect results in an unpleasant impression of drying of the skin accompanied by a feeling of stretching, which occur a few minutes after use when all the water used has evaporated and the freshness provided by it has disappeared.
- Standard type talcs have already been used as a filler of soaps in order to reduce the cost of the products obtained and sometimes, to increase the impression of softness felt during cleaning (due to the lamellar nature of the talc); however, the softening obtained during use is not linked to the drying experienced after use, and these known products always exhibit drying properties, once the water used has evaporated.
- the present invention aims to reduce the drying properties of a soap based on fatty acid salts so as to suppress the unpleasant sensation of drying resulting from the action of the soap, when the water used during cleaning has evaporated. .
- the aim of the process of the invention is to create on the skin, during use, a film replacing the natural lipid film which is destroyed or damaged by the soap.
- the impression of drying is due to the destruction or ' deterioration of this lipid film which protects the epidermis and forms a barrier limiting the surface dehydration of the skin.
- this lipid film is dissolved by fatty acids. because of their surfactant properties.
- an abnormal dehydration occurs on the surface of the epidermis with as a consequence the aforementioned unpleasant sensations (drying, stretching) and risks of alteration of the skin.
- the invention proposes to create on the skin, when using soap, a stable protective film replacing the natural lipid film in order to limit the surface dehydration of the epidermis until the natural lipid film is reconstituted.
- the process of the invention consists in adding to the soap a talc combining the following characteristics:
- talc is meant either the hydrated magnesium mineral silicate, or the chlorite mineral (hydrated magnesium and aluminum silicate), or a mixture of the two, associated where appropriate with other minerals (dolomite, etc. ), or again, a substance derived from talc, having similar properties.
- mean diameter D50 is meant a diameter such that 50% of the grains by weight have a size smaller than said diameter; by “diameter 095" is meant a value such that 95% of the grains by weight have a size less than said value.
- the packed bulk density of a powder is defined by the AFNOR standard NFT30-042.
- NFT30-042 For a talc, it gives an image of the shape of the grains: in fact, with equivalent particle size distribution, a talc having very elongated lamellar grains has a compacted bulk density less than a talc having less granular grains elongated (more spheroid).
- this parameter can be considered in practice for talc as a coefficient making it possible to assess the shape of the particles thereof.
- the invention comes from the following observation, made during series of comparative tests: surprisingly, a significant reduction in the drying properties of a soap is obtained when talcs are incorporated therein, the grains of which have slightly elongated, relatively spheroidal shapes (that is to say for which the basal area / lateral area ratio is not very high), insofar as the grain size does not exceed the above values.
- a microcrystalline talc which, by nature, has grains of more spheroid shape, each grain being constituted by elementary particles linked together, these elementary particles of size less than or equal to 1 micron having no orientation privileged.
- a talc of the lamellar type having undergone a grinding capable of at least partially breaking its lamellae (impact grinding or the like).
- a microcrystalline talc is used combining the following characteristics:
- the average diameter D50 is between 2 and 5 microns and the diameter D95 is between 6 and 14 microns.
- a hydrophobic talc protective film is formed on the surface of the skin which has sufficient stability to remain in place during rinsing and to act as a barrier limiting the passage of water molecules and therefore the dehydration of the epidermis, until reconstitution of the lipid film destroyed by the action of soap.
- talc a talc having an iron content of less than approximately 1.0% is preferably used in order to avoid any risk of degradation of the soap over time (this iron content being the total iron content expressed in the form of F2O3 ).
- the invention extends to cleaning compositions with low desiccant properties, obtained 'by carrying out the above method, by adding to a soap a talc having the previously described characteristics.
- the soap samples were conditioned for 24 h at a temperature of 20 ° C and 60% relative humidity.
- the temperature of the water used was 40 ° C. with a flow rate of 1 l / min.
- the method consists in subjecting a known quantity of powder to packing conditions defined in standard AFNOR NF T 30-042.
- the apparent density of the packed product is calculated by the ratio of the mass used to the volume occupied after packing, according to the formula:
- Mo is the mass in grams of 1 empty test tube
- V is the volume read, in cm3, after packing.
- the particle size analysis was done by a "Sedigraph 5000" device (registered trademark) the method is based on the measurement of the solid concentration (by absorption of an X-ray beam) of a suspension during sedimentation by gravity. It applies to powders whose grains have diameters between 0.5 and 100 ⁇ m.
- the device directly plots the distribution curve expressed as a percentage of passing according to the diameter of Stocks:
- the soap base contains water (around 13%) and this water added in the talc formulation keeps the overall water content of the two formulations constant.
- the talc / soap premix is produced in a conventional ribbon mixer. The final stages of soap making from the premix are traditional (grinding, refining, extrusion, cutting, pressing).
- Example 1 demonstration of the reduction in the drying properties of the additive soap.
- Example 2 demonstration of the influence of the particle size distribution.
- talc B gives a significantly higher result compared to the reference soap without talc and to the soap containing talc C not in accordance with the process of the invention.
