    [0032] As discussed herein, in one aspect of the present invention, there is provided use of (i) water, (ii) sugar, sorbitol or a mixture thereof and (iii) humectant for improving heat transfer to a soap.

    [0033] As discussed herein, in one aspect of the present invention, there is provided a soap base for preparing a solid soap, the soap base comprising

    (i) soap in an amount of from 20 to 50% by weight of the total composition,
    (ii) water in an amount of from 8 to 40% by weight of the total composition,
    (iii) sugar, sorbitol or a mixture thereof, wherein the combined amount of sugar and sorbitol is from 2 to 15% by weight of the total composition, and
    (iv) humectant in an amount of from 5 to 40% by weight of the total composition.
    wherein the soap base comprises ethanol in an amount of no greater than 5% by weight of the total composition.

    [0034] As discussed herein, in one aspect of the present invention, there is provided a process for the production of a soap comprising the steps of

    (a) providing a soap base comprising: [0035] (i) soap in an amount of from 20 to 50% by weight of the total composition, [0036] (ii) water in an amount of from 8 to 40% by weight of the total composition, [0037] (iii) sugar, sorbitol or a mixture thereof, wherein the combined amount of sugar and sorbitol is from 2 to 15% by weight of the total composition, and [0038] (iv) humectant in an amount of from 5 to 40% by weight of the total composition
    (b) heating the soap base to a temperature of from greater than 80 C. to less than 100 C., and
    (c) cooling the heated soap base to provide the soap.

    [0039] As discussed herein, the soap is a solid soap. Solid products of the present invention are compositions which can substantially sustain their physical shape when unsupported by external means, e.g. packaging etc. Thus, they are considered to be solid, solid like, in solid form or in solid-like form at room temperature. For the avoidance of doubt the solid product must remain substantially solid at up to 30 C.

    [0040] By solid-like, it is understood that some materials are considered on a day to day basis to be solid, yet over an extremely long period of time, may alter in shape, e.g. amorphous materials such as glass etc. However, they are considered to be solid-like as, for the purpose they fulfil, they are solid. The solid form of the solid compositions of the present invention means that external packaging is not required to maintain the shape of the composition.

    Example 3

    Skin Sensitisation

    Methods

    [0115] The KeratinoSens test detects the potential of the test item to activate cells known as keratinocytes, which are derived from the epidermis of human skin. A specialised gene for a marker called luciferase has been inserted into the cells. In the presence of a skin sensitiser, luciferase is activated and causes the emission of a light signal, which is measured in the test. Induction of luciferase activity by >1.5-fold above untreated controls results in classification as a skin sensitiser.

    [0116] The Direct Peptide Reactivity Assay (DPRA) measures the potential of a test item to bind to two building blocks of skin proteins called cysteine and lysine. The test item is dissolved in an appropriate solvent and incubated with cysteine or lysine for 24 hours.

    [0117] Peptide depletion is measured by High Performance Liquid Chromatography (HPLC). The percentage depletion value determines the reactivity class of the test item as minimal, low, moderate or high. The minimal reactivity class results in a prediction that the test item is a non-sensitiser; the low, moderate or high reactivity classes result in a prediction that the test item is a skin sensitiser.

    [0118] Skin sensitisation is a complex pathway of events, leading to inflammation. It is often associated with repeat exposure during long term use of a cosmetic product, during which an individual can become sensitised to one or more ingredients within the formulation. The human skin sensitisation potential of two soaps were assessed using two validated in vitro methods, looking at two different points in the sensitisation pathway: the Direct Peptide Reactivity assay (DPRA) to determine skin protein binding, and the KeratinoSens test to determine keratinocyte activation.

    [0119] The two soaps tested were (i) a sorbitol based soap prepared in accordance with Example 2 and (ii) an analogous soap in which propylene glycol was used in place of the sorbitol.

    [0120] The combined use of these two tests is in line with current recommendations from the European Centre for the Validation of Alternative Methods (ECVAM). At the time these compositions were assessed the test methods were draft OECD Guidelines. However the KeratinoSens and DPRA guidelines have subsequently been approved by the OECD for the in chemico and in vitro skin sensitivity assessment of chemical entities (KeratinoSens: OECD Testing Guidelines 442D and DPRA: OECD Testing Guidelines 442C). It is expected that these guidelines are to be incorporated into REACH by 2016.

    [0121] These tests were performed in XCellR8's GLP (Good Laboratory Practice) accredited laboratory without the use of any animal-derived components, ensuring a fully animal-free testing strategy.

    [0122] In the DPRA test, propylene glycol containing soap was classified as a non-sensitiser to human skin. However, in the KeratinoSens test, the propylene glycol containing soap was classified as a skin sensitiser. Overall, the test results suggest that the propylene glycol containing soap may have some sensitisation potential through the activation of human skin cells (keratinocytes), which may result in inflammation in susceptible individuals.

    [0123] In contrast, in both the DPRA test and the KeratinoSens test, the sorbitol based soap was classified as a non-sensitiser to human skin.

    [0124] The DPRA data is provided in the table below

    TABLE-US-00005 Mean % Cysteine Cysteine % Lysine % and Lysine Test Item Depletion Depletion Depletion Sorbitol based soap 1.0% 0% 0.5 Propylene glycol 3.8% 0% 1.9% based soap

    [0125] The KeratinoSens test data can be seen in FIGS. 1 and 2.
