This application is a National Stage Application of PCT/GB2013/051700, filed 27 Jun. 2013, which claims benefit of Serial No. 1211531.7, filed 29 Jun. 2012 in Great Britain and which applications are incorporated herein by reference. To the extent appropriate, a claim of priority is made to each of the above disclosed applications.
The present invention relates to a solid product for use as a cosmetic, a process for producing said product, and a product prepared by the method.
The present invention relates to products particularly those for use in contact with the human body.
The history of soap and its use in cosmetics dates back many hundreds of years. It has therefore a very long history of safe use. The properties of soap and its manufacture make it very interesting from an environmental perspective. Soaps are salts of fatty acids and can be made from a number of fatty sources. Traditionally soap was made from tallow. Over the last few decades it has been made from vegetable oils in response to a demand for non-animal based products. Soap is a relatively simple material and it can be manufactured locally by cosmetic manufacturers, unlike synthetic detergents whose manufacture is far more complicated and beyond normal manufacturing capabilities. Soap is an alkaline medium. As such it does not require cosmetic preservatives. It is a solid medium so it does not require packaging to contain it. All these considerations make it an exceptional material and its versatility is extremely useful.
Soap and surfactants have been provided in many physical forms. One form previously provided has been as ‘paper’ type sheet. For example cellulose derivatives can be combined with surfactants to form a paper like product. These paper type products have been typically either fragile flakeable materials or thick sheets. However, owing to the constraints of the ingredient materials, ‘paper’ type products which are foldable and pliable have not been prepared.
The present invention seeks to provide a solid cosmetic product which is foldable without snapping and which can be used in the manner of paper, for example as a wrapping material, as well as being a soap product that can be washed with.
In a first aspect, there is provided a solid cosmetic composition comprising
(i) sugar;
(ii) a vegetable fibre, a fruit fibre or mixture thereof; and
(iii) a soap;
wherein the solid cosmetic composition is prepared by dehydrating a liquid composition comprising
(i) sugar in an amount of 33.75 to 47 wt. %;
(ii) a vegetable fibre, a fruit fibre or mixture thereof, in an amount of 3.75 to 4.75 wt. %;
(iii) a soap in an amount of 20 to 75 wt. %; and
(iv) water in an amount of 11 to 15 wt. %,
wherein the amounts are based on the total combined amount of the sugar, the fibre, the soap and the water.
In a second aspect, there is provided a solid cosmetic composition comprising
(i) sugar;
(ii) melon fibre; and
(iii) a soap,
wherein the solid cosmetic composition is prepared by dehydrating a liquid composition comprising
(a) melon; and
(b) a soap.
In a third aspect, there is provided a solid cosmetic composition comprising
(i) sugar;
(ii) a vegetable fibre, a fruit fibre or mixture thereof; and
(iii) a soap;
wherein the solid cosmetic composition is prepared by dehydrating a liquid composition comprising
(i) sugar in an amount of 6.75 to 8.6 wt. %;
(ii) a vegetable fibre, a fruit fibre or mixture thereof, in an amount of 0.75 to 0.95 wt. %;
(iii) a soap in an amount of 5 to 25 wt. %; and
(iv) water in an amount of 67.5 to 85.5 wt. %,
wherein the amounts are based on the total combined amount of the sugar, the fibre, the soap and the water.
In a fourth aspect, there is provided a process for preparing a solid cosmetic composition comprising
(i) sugar;
(ii) a vegetable fibre, a fruit fibre or mixture thereof; and
(iii) a soap;
the process comprising the step of
(a) providing a liquid composition comprising
(b) dehydrating the liquid composition to provide the solid cosmetic composition.
In a fifth aspect, there is provided a product obtained or obtainable by a process in accordance with the present invention.
For ease of reference, these and further aspects of the present invention are now discussed under appropriate section headings. However, the teachings under each section are not necessarily limited to each particular section.
We have surprisingly found that by providing a solid cosmetic composition comprising the specific components of the present invention as described herein, a soap is formed having physical characteristics which give a paper like texture. The present invention provides a solid cosmetic composition which may be used in the form of packaging, which can be used to wrap other products. This wrapping material can be used to protect them, for example in a retail environment. It is also possible to print information on to the compositions of the present invention, so we have surprisingly found that we may provide a wrapping, which for example explains the contents of the product within. When the wrapping made from the composition of the present invention has been removed, it can subsequently be used to wash the skin. This is highly advantageous because the packaging is used for a further purpose and does not create any solid waste, for example which has to be collected for recycling or which would end up in land fill. This is an exceptional aspect as the creation of excessive packaging is environmentally challenging.
The present invention provides a form of paper prepared from soap (with the addition of water), fibre and sugar. This forms an excellent paper like texture. It has been surprisingly found that a blend of these ingredients when dehydrated formed a durable material which has the desired properties.
