Abstract

An aqueous based barrier cream contains at least one sucrose ester surfactant, a fatty emollient, a filler, and at least one Group 2 or Group 3 metal soap of a fatty acid having 8 to 20 carbon atoms. The cream is biodegradable and contains no petroleum derivatives.

Description

SPECIFICATION Barrier creams This invention relates to barrier creams, particularly for use on the hands, which are resistant to water or other industrial solvents.
Water-resistant barrier creams in general comprise an oily, water-repellent material, e.g. paraffin jelly, water and a filler which is usually an inorganic powder, such as kaolin, together with emulsifying materials in order to form an aqueous cream. We have now found that a particular combination of biodegradable materials forms an efficient barrier cream which contains no petroleum derivatives.
According to the present invention we provide an aqueous based barrier cream containing surfactant, fatty emollient and filler and characterised by containing at least one sucrose ester as the surfactant, together with at least one Group 2 or Group 3 metal soap of a fatty acid having 8 to 20 carbon atoms. The metal soap is preferably an alkaline earth metal soap and is conveniently a calcium or magnesium soap and may be prepared by reacting the free fatty acid or an alkali metal soap thereof with a solution containing ions of the required Group 2 or Group 3 metal. The metal soap should preferably comprise from 2.5 to 7.0 % by weight of the total barrier cream.
The sucrose ester material employed as surfactant should contain a relatively high proportion of sucrose monoesters and diesters and a relatively small proportion of sucrose higher esters. For preference the sucrose ester material should (preferably) comprise a mixture of monoesters and diesters with substantially no higher esters, in which the monoesters form the major part.
The sucrose ester material may comprise a single sucrose ester of one fatty acid within the stated range, but will generally comprise a mixed sucrose ester of several fatty acids, such as that derived from a naturally occurring triglyceride fat. Fatty acids with 12 to 18 carbon atoms are particularly prefered. The sucrose ester material should be present in the barrier cream preferably at a level of from 1.8 to 5.0% by weight.
The fatty emollient component of the cream may comprise substances normally used for the purpose, such as lanolin and its derivatives, either alone or together with other fatty material. The cream preferably contains a proportion of mixed glycerides, that is to say a mixture of monodi- and triglycerides, particularly at a level of from 1.3 to 3.5 % by weight of the cream.
The metal soap is a soap of a Group 2 or Group 3 metal, for example an alkaline earth metal such as calcium or magnesium, or a Group 3a metal such as aluminium. Naturally, the metal must be non-toxic and suitable for inclusion in a skin-care product.
Conveniently, the metal soaps, the sucrose ester material and the mixed glycerides may be added to the cream formulation in the form of an intimately mixed paste. Such a paste may be obtained by reacting a crude sucrose ester product obtained in a transesterification reaction and containing sucrose esters, mixed glycerides and alkali metal fatty acid soaps, with a solution containing a Group 2 or Group 3 metal, especially alkaline earth metal, ions. The crude reaction mixture is conveniently that obtained according to U.K. Patent Specification No. 1,399,053.
A process for the conversion of the alkali metal soaps in the crude product into salts of Group 2 or Group 3 metals is given in U.K. Patent Specification No. 1,500,341, and comprises coagulation of the crude transesterification product in, for example, warm aqueous calcium chloride. The solid material obtained after removal of the aqueous phase can be incorporated directly into the barrier cream formulation according to the present invention.
The filler incorporated in the cream may be any suitable filler normally used in barrier cream formulations, for example an inorganic particulate material, especially a clay such as kaolin. It is conveniently present in the formulation at a level of from 8 to 10% by weight.
Other components which may be incorporated include thickening and texture-modifying agents such as cetyl alcohol and film forming agents, particularly for use in formulations to protect the hands against industrial solvents and resins, for example carboxymethyl cellulose, e.g. the material sold under the Trade Name Courlose F 20 G (Trade Mark).
Thus, in a particularly preferred embodiment of the barrier cream formulation according to the present invention, a mixture of Group 2 or Group 3 metal fatty acid soaps, sucrose mono- and di-esters of fatty acids, mixed glycerides and, optionally, a small proportion of sucrose (e.g. up to 2% by weight of said mixture) is combined with a fatty emollient such as lanolin and an inorganic filler such as kaolin, optionally together with cetyl alcohol andlor a film forming agent, and water to give an aqueous emulsion to be used as a barrier cream.
Typical preferred weight ranges of components according to the present invention are given in the following table: Group 2 or Group 3 metal fatty acid soap 2.5 to 7.0%; Sucrose mono- and di-esters 1.8 to 5.0%; Mixed glycerides 1.3 to 3.5%; Sucrose up to 0.3%; Lanolin or other fatty emollient 3.0 to 7.0%; Kaolin or other filler r 8.0 to 10.0%; Cetyl alcohol 3.0 to 7.0%, Film forming agent upto 2.0%; and Water ad 100% Teetotal emulsified material (excluding the water) should preferably comprise from 25 to 35% by weight of the total, e.g. about 30% by weight.
The following examples illustrate preferred methods of formulation (all parts are by weight): Example 1 Water Repellent Cream A mixture of calcium soaps, sucrose mono- and di-esters, mixed glycerides and containing a trace of sucrose, having the approximate composition Calcium soaps 30-50% by weight Sucrose esters 20-35% by weight Glycerides 15-25% by weight (11.5 parts), cetyl alcohol (5 parts), lanolin (5 parts) and kaolin (9 parts) was combined with water (to a total of 100 parts), heated to a temperature of at least 55"C and intimately blended with stirring. Stirring was continued while the mixture was cooled and perfume was added at about 30"C. The mixture thickened on standing.
Example 2 Resin and Solvent Resistant Cream The calcium soap/sucrose ester/glyceride mixture used in Example 1 (11.5 parts), cetyl alcohol (5 parts), lanolin (5 parts) and kaolin (9 parts) were mixed with water (18 parts) and mixed at 55-60 C. Courlose F 20 G (Trade Mark) (1.5 parts) was mixed with water (50 parts) and this mixture was added to the first mixture with stirring at 55-60 C. The combined mixture was then stirred and cooled. The mixture thickened on standing.
