Definitions
- Lanolin fat extracted from sheep's wool, is commonly used by the cosmetic and pharmaceutical industries for its emollient, moisturizing, emulsifying properties and its water absorption capacity.
- the Applicant has filed a patent application FR N ° 01 08905 concerning an original and economical process for obtaining a lanolin substitute and derivatives (lanolin alcohol ...), capable of absorbing up to at least twice its weight in water or aqueous solution or aqueous suspension.
- the substitute for lanolin and derivatives forms real emulsions, stable over time with a water retention power greater than that of lanolin and it also has the properties emollient, moisturizing and occlusive known to lanolin, without having the disadvantages.
- the Applicant proposes in this present invention to further improve the organoleptic and physicochemical characteristics of the lanolin substitute and derivatives (lanolin alcohol, etc.) described in said aforementioned patent: the new lanolin substitutes and derivatives (alcohol lanolin ...) retain the properties of the previous one (water absorption, hydration, emollience %) but they also meet other criteria very important for the industry such as touch, color, index d 'iodine and the melting point.
- the objective of such an invention is to obtain lanolin substitutes and derivatives (lanolin alcohol, etc.) which bring complete satisfaction whatever the application concerned, which is impossible to date.
- Lanolin is a solid, amber-yellow wax with a characteristic odor. It is insoluble in water but soluble in hot ethanol, ether and chloroform.
- Lanolin is made up of carbon chains that can range from C14 to C30. Its composition is complex: Free acids; Esters of triterpene alcohols and sterols; Esters of aliphatic alcohols; sterol monohydroxyesters, alcohols aliphatic and triterpenic; Free aliphatic alcohols; Triterpenic alcohols and free sterols; Di and polyhydroxy esters and free diols; Oxidation derivatives; hydrocarbons
- Lanolin is extracted from sheep's ointment, a sebaceous material secreted by the sweat glands of the animal.
- The. grease represents 15 to 75% of the weight of the wool fibers.
- Lanolin is widely used in cosmetics and dermatology for its emollient, hydrating, emulsifying, occlusive properties. It softens the skin, protects it and prevents its dehydration. Lanolin also has the power to absorb up to 4 times its weight in water. In addition, it is not very sensitive to oxidation.
- the extremely numerous lanolin derivatives obtained by physical or chemical transformation, having better odor, color and touch characteristics, are preferably used.
- lanolin and its derivatives are used in the composition of many preparations such as: bubble baths, lipsticks, creams, shaving creams, after shave lotions, powders, soaps, shampoos.
- Lanolin is also used in the industrial sector with various applications: waxes, printing inks, anti-rust and anti-corrosion protective films deposited on certain metals, leather and fur industry for waterproofing, paints ...
- lanolin is increasingly criticized for the following reasons:
- the Applicant proposes in this present invention to further improve the organoleptic and physico-chemical characteristics of the lanolin substitute and derivatives (lanolin alcohol, etc.) described in said aforementioned patent.
- the present invention provides new lanolin substitutes and derivatives (lanolin alcohol, etc.), which not only have the properties of the previous lanolin substitute and derivatives (lanolin alcohol, etc.), described in said aforementioned patent (ability to absorb up to twice its weight in water, formation of stable emulsions, hydration, emollience, occlusiveness) but also other organoleptic and physicochemical characteristics of lanolin such as touch, color, index iodine and melting point.
- lanolin substitutes and derivatives can be used in all current and future applications of lanolin.
- the invention is particularly, but not limited to, heat treatment of saturated and / or unsaturated fatty acids, esters of saturated and / or unsaturated fatty acids, saturated and / or unsaturated hydrocarbons or derivatives saturated and / or unsaturated thereof and of compounds comprising or generating hydroxyl functions, such as glycerol, preferably without catalyst and in an oxygen-free atmosphere.
- the present invention provides new lanolin substitutes and derivatives (lanolin alcohol, etc.).
- lanolin substitutes and derivatives are obtained by hemisynthesis from a mixture of saturated and / or unsaturated fatty acids, esters of saturated and / or unsaturated fatty acids, hydrocarbons. saturated and / or unsaturated or saturated and / or unsaturated derivatives of the latter and of compounds comprising or generating hydroxyl functions, such as glycerol, preferably without catalyst and in an atmosphere devoid of oxygen.
- the invention relates to the properties of these products:
- the emulsions formed are stable over time and after several passages in an oven at 40 ° C. This phenomenon is not observed for lanolin which releases all its water in less than 15 days.
- the products are emollients, moisturizers, emulsifiers and occlusive. They soften the skin, protect it and prevent its dehydration.
- the particularity of this invention comes from the combination of the reagents used in the reaction medium: - reagents including unsaturations (acids, esters, hydrocarbons and their derivatives)
- the invention therefore relates to the general process characterized in that the combination of the above reagents is reacted in the reaction medium.
- the invention also relates to new industrial products which in themselves have properties which clearly distinguish them from previously known industrial products.
- Reagents comprising unsaturations (acids, esters, hydrocarbons and their derivatives) make it possible to obtain polymers of unsaturated fatty acids, esters of unsaturated fatty acids, unsaturated hydrocarbons, unsaturated derivatives of these compounds, alone or in mixture.
- This process is described in patent application FR 98 13770 and PCT patent application WO 00/26265 (PCT / FR99 / 02646) to which a person skilled in the art can refer.
- the emulsions obtained are not stable: the water is released in less than 24 hours.
- Reagents containing or generating hydroxyl functions called 'OH reactants': (0.05 to 60%) A sufficient quantity of "OH-reactants", that is to say comprising or generating hydroxyl groups, is added to the reaction medium.
- the products obtained have emollient, hydrating and occlusive properties, but also absorb up to at least twice their weight in water.
- the emulsions formed are now stable over time and after several passages in an oven at 40 ° C. This phenomenon is not observed for lanolin which releases all its water in less than 15 days. These products have a higher water retention capacity than lanolin.
- the preferred compounds are fatty acids or esters of fatty acids containing at least one OH on their chain or alcohols such as glycerol, sterol.
- Reagents with a high melting point increase the melting point of the product formed and give it a pasty to semi-solid or even solid appearance, comparable to that of lanolin.
- reagents often have low iodine numbers. They thus reduce the iodine index of the product and thus approach that of lanolin. In the same way, this gives it better stability over time. Indeed, the risk of oxidation by unsaturations, which are few in the product, is limited.
- This addition of reagents, used initially to increase the melting point therefore surprisingly provides several surprising properties.
- fatty acids or esters of fatty acids in particular hydroxystearic acid or an ester of this acid, will be used.
- the melting points are adjusted between 36 and 40 ° C corresponding to that of lanolin or around 50 ° C to compare with lanolin alcohol
- Lanolin is a wax, consisting of sterols and fatty alcohols with short and long carbon chains ranging from C14 to C30.

- the conventional heat treatment is carried out between 100 and 400 ° C and better still between 230 and 350 ° C, with permanent stirring and preferably without catalyst and under an inert atmosphere.
- the reaction temperature depends on the boiling and / or degradation temperatures of the constituents of the mixture.
- the total reaction time depends on the reagent (s) used and the viscosity which it is desired to obtain. It is preferably between 3 hours and 24 hours, preferably between 3 hours and 10 hours.
