FIELD OF THE INVENTION

The present invention relates to a solid cosmetic product, a process for producing said product, and a product prepared by the method.

BACKGROUND TO THE INVENTION

The present invention relates to products particularly those for use in contact with the human body.

Therapeutic bathing products are known in the cosmetic industry and are available in a variety of different forms. Bath salts, oils, and lotions are a few examples of bathing products that can deliver emollients, essential oils and fragrances to a bath, providing calming and remedial properties. However, the required use of solid packaging for these products is a significant disadvantage due to the environmental impact that waste packaging has, despite the availability of recycling.

For at least this reason encapsulated compositions for creating therapeutic bath products have become increasingly popular. For example, US4,294,855 and W003/061633 disclose compositions which are capable of enveloping a core cosmetic. The active therapeutic components are often encased in a gelatinous or membrane-bound shell, which dissolves on contact with water, releasing the core ingredients into the water. However, the disadvantage of these products is that the shell does not readily dissipate in water, delaying the release of the active ingredients, whilst providing no effective benefit of its own. They are also prone to rupturing, resulting in a wasted and suboptimal product.

In addition to the problems of providing bathing products which do not require unnecessary packaging, it is also found that users sometimes wish to enjoy the fragrance of their purchased product without the need to bathe in the product. To achieve this aim, it is often necessary for users to buy a separate fragranced product such as a “reed diffuser”. This results in further cost to the user and a potential for further unnecessary packaging and transport waste. The present invention seeks to provide a solid cosmetic product that may be used as a therapeutic bathing product and is capable of delivering a concentrated dose of emollients, essential oils and/or fragrances with an enhanced experience for the user, and which also may be used to deliver fragrance other than when the user is bathing.

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.

Advantages

We have identified that by providing a solid cosmetic composition as described herein, a composition is prepared which may be used in at least two ways.

In a first use, the solid cosmetic composition may be deposited in bathing water and will be dispersed in that water. In other words, a bathing oil may be provided which is delivered in solid form. The solid product holds its form and does not readily melt prior to use. By virtue of this property, it is possible to sell the product without unnecessary packaging. The vegetable butter acts as an excellent carrier for oils, colours and other ingredients, which are desirable for their tranquilising and visual properties, while simultaneously possessing excellent emolliating properties of their own. It was found that it was preferable to use soft vegetable butters for the composition, particularly as the melting point of a soft vegetable butter would allow the composition to readily melt and dissipate. For the avoidance of doubt, there is no predefined bathing temperature range for human use, although it is widely accepted that a comfortable bathing temperature is slightly above human body temperature (on average 37°C) and that an unbearable bathing temperature would be above 47°C.

In addition, we have found that by selecting the particular first emulsifier and second emulsifier required by the present invention, the emulsifier combination is able to emulsify the fats and one or more colours present in the product to produce a pleasant visual effect whereby the colouring and/or fats are effectively dispersed throughout the bathing water. In a second use, the solid composition may be heated to melt the solid product and to release fragrance from the product. This usage may typically be performed by placing the product in a “wax melt burner”. These “burners” are well-known to those skilled in the art and to users of fragrance products. They typically contain a dish portion in which a solid product is placed and to which heat is applied. This heat may be provided electrically or from a small flame such as a candle. Although these devices are referred to as “burners” the product itself is not combusted. Instead, fragrance in the product which is volatile is released during the heating and provides the desired fragrance release for the user. When the fragrance is no longer required, the heat source is removed and the product solidifies. It may then be reused. The present inventors found that previously when one heated a product which is suitable for cosmetic use, such as a bath oil, numerous problems occurred. In particular, the one or more colours present in the cosmetic product would separate from the vegetable butter during heating and would pool at the bottom of the liquid heated product. This resulted in difficulty in removing the solidified product after cooling from the heating bowl. The solidified product would have a layer of highly concentrated colouring that would stain the hands of the user and other contact surfaces. The solidified product may also be difficult to remove from the bowl, adhering to the bowl and/or breaking up on removal. It was found that by providing a product having both the specific combination of emulsifiers and requiring the presence of the inert powder, these problems could be overcome. In particular, the emulsifiers would assist in the dispersion of the one or more colours within the vegetable butter and the inert powder would be deposited on the bottom of the bowl during the melting of the product and provide a layer between the bowl and the remaining product. This would allow for ease of removal of the solidified product after use.

The present inventors have therefore found that a specific combination of a first emulsifier having a HLB value of from 2 to 9; a second emulsifier having a HLB value of from 10 to 20; and one or more inert powders in an amount of from 0.5 to 25 wt.% based on the solid cosmetic composition, allows for the provision of a solid composition which has both a cosmetic application and a fragrance delivery application. In particular, this specific combination of components allows for the delivery of vegetable butter in bathing water, together with dispersion of colours, to offer both a visually appealing and emollient bath. Furthermore, this specific combination of components allows for the same composition also to be used as a “melt” for the delivery of fragrance upon heating. After solidification this product may be easily removed from the heating bowl. The provision of a product which is cosmetically acceptable and can deliver these dual uses, is highly surprising.

DETAILED DESCRIPTION

Composition

As discussed herein, in one aspect of the present invention, there is provided a solid cosmetic composition comprising

(a) vegetable butter;

(b) a first emulsifier having a HLB value of from 2 to 9;

(c) a second emulsifier having a HLB value of from 10 to 20;

(d) one or more inert powders in an amount of from 0.5 to 25 wt.% based on the solid cosmetic composition;

(e) one or more colours; and

(f) one or more fragrances.

It will be understood by one skilled in the art that the nature of a cosmetic product means that the product is not edible. Thus in a further aspect the present invention provides a nonedible solid cosmetic composition comprising

(a) vegetable butter;

(b) a first emulsifier having a HLB value of from 2 to 9;

(c) a second emulsifier having a HLB value of from 10 to 20;

(d) one or more inert powders in an amount of from 0.5 to 25 wt.% based on the solid cosmetic composition;

(e) one or more colours; and

(f) one or more fragrances. The 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.

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.

Due to the solid form of the compositions of the present invention, external packaging is not required to maintain the shape of the composition.

The vegetable butters used in the present invention are triglycerides, which are found to be solid (including solid-like, discussed above) at normal usage temperatures. The term vegetable butter is understood by one skilled in the art and means a triglyceride obtainable from vegetable source which has the consistency of a butter. It is understood by one skilled in the art that a triglyceride obtainable from vegetable source may be a triglyceride obtained from vegetable source which is then subjected to modification provided it remains a triglyceride. For example, a triglyceride obtained from vegetable source may be subjected to hydrogenation to increase the degree of saturation and the solid fat content to provide a vegetable butter. For the avoidance of doubt the vegetable butter is a triglyceride which remains substantially solid at up to 30°C. It will be appreciated however that it is not a requirement that the vegetable butter have a solid fat content of 100% at normal usage temperatures. In a preferred aspect the vegetable butter is a triglyceride having a solid fat content of at least 70%, preferably at least 80%, preferably at least 90%, preferably at least 95%, preferably at least 98%, preferably at least 99% at 25°C.

The vegetable oils used in the present invention are triglycerides, which are found to be liquid at normal usage temperatures. For the avoidance of doubt the vegetable oil is a triglyceride which remains substantially liquid at up to 30°C. It will be appreciated however that it is not a requirement that the vegetable butter have a solid fat content of 0% at normal usage temperatures. In a preferred aspect the vegetable oil is a triglyceride having a solid fat content of no greater than 30%, preferably no greater than 20%, preferably no greater than 10%, preferably no greater than 5%, preferably no greater than 2%, preferably no greater than 1% at 25°C.

In one aspect the composition of the present invention is made by moulding of the product. A typical process comprises the steps of: (i) preparing a first composition comprising (a) vegetable butter; and (b) a first emulsifier having a HLB value of from 2 to 9; (ii) preparing a second composition comprising (c) a second emulsifier having a HLB value of from 10 to 20; (d) one or more inert powders; (e) one or more colours; (f) one or more fragrances;

(iii) combining the first composition with the second composition, wherein the one or more inert powders are present in an amount of from 0.5 to 25 wt.% based on the solid cosmetic composition, placing in a mould and allowing to solidify to form the solid cosmetic composition.

As noted herein, in one aspect the one or more inert powders may comprise at least hydrated silica. In one aspect the one or more inert powders consists of hydrated silica. We have found that hydrated silica is particularly advantageous as it modifies the viscosity of the vegetable butter (fat) when the product is melted in use. In particular, the hydrated silica is found to thicken the liquid fat and thereby reduce the settling out of colours and other materials prone to sedimentation. These colours and other materials are more easily suspended in systems comprising hydrated silica and/or increased amounts of colours and other materials prone to sedimentation may be provided in compositions comprising hydrated silica owing to this advantageous property of hydrated silica. We have also found that hydrated silica may gather at the bottom of the vegetable butter (liquid fat) when melted in use and provides a localised area of high viscosity at the bottom of the liquid fat. This reduces the tendency of the composition to adhere to the surface of the burner on cooling and improves the ease of removal of the solidified composition from the burner. Thus, in one aspect there is provided a solid cosmetic composition comprising

(a) vegetable butter;

(b) a first emulsifier having a HLB value of from 2 to 9;

(c) a second emulsifier having a HLB value of from 10 to 20;

Example

The invention will now be described with reference to the following non-limiting examples. Each of the six inert powders were tested at amounts of 0.1 wt%, 0.5wt%, 1wt%, 5wt%, 10wt% and 20wt% based on the solid cosmetic composition. The details of each of these formulations is provided below. 0.1 wt.% Inert Powder

0.5 wt.% Inert Powder

1 wt.% Inert Powder wt.% Inert Powder wt.% Inert Powder wt.% Inert Powder

The following method was used in each case

1. Warm A gently to 60°C to melt

2. Temper the mixture (cool down the butters and oils to 27°C and then heat them back up to 37°C before cooling again)

3. Mix B and add to A when below 37°C

4. Pour when the mix is below 25°C or when the mix is opaque

Each of the prepared products was placed in a “wax burner” and heated until fully molten using a candle placed below the bowl of the wax burner. The candle was then extinguished and the products allowed to solidify. Once the products had fully cooled, the solidified product was removed from the bowl of the wax burner. The observed results of the trials were as follows. The images of the products are also show in the figures.
