PRODUCT

FIELD OF THE INVENTION

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

BACKGROUND TO THE INVENTION

The earliest systematic exposition of the different kinds of salts and their uses, including medicinal bathing, was published in China in approximately 2700 BC. Hippocrates the ancient Greek physician encouraged his fellow ‘healers’ to make use of salt water to heal various ailments by immersing their patients in seawater. The ancient Greeks continued this trend and in 1753 English author and physician Dr Charles Russell popularised the practice in his ‘Uses Of Sea Water’.

The term ‘salts’ comes from their appearance being similar to the crystals of common salt. Such salt include magnesium sulphate also known as Epsom Salts, Sodium Chloride, Sodium Bicarbonate (Baking Soda), Sodium Sesquicarbonate & Sodium Citrate. Salts convey a myriad of beneficial qualities to a user whilst bathing, such as cleansing, softening and exfoliating the users skin during bathing, in addition to softening the water, thereby changing the way in which surfactants and soap behave in a bath.

One of the most popular forms of the bath salt is the Bath Bomb™. The bath bomb dates from the early 20th Century and may be considered a form of bath salt, as they typically consist of at least one salt of carbonic acid, and at least one acidifying agent. When a bath bomb is placed into water it vigorously effervesces, releasing carbon dioxide. The reaction is an acid-base reaction resulting in the production of a salt, carbon dioxide gas and water.

Whilst previous bath bombs have provided the user with the above mentioned beneficial qualities, it is desirable to enhance the experience of using bath bombs and other effervescent products.

SUMMARY OF THE INVENTION

In a first aspect, the present invention relates to a cosmetic product comprising an effervescent material and an electronic device.

In a further aspect, the present invention relates to a process for preparing a cosmetic product comprising an effervescent material and an electronic device, said process comprising combining an electronic device with an effervescent material.

In a further aspect, the present invention relates to a cosmetic product obtained or obtainable by combining an electronic device with an effervescent material.

In a further aspect, the present invention relates to a kit comprising an electronic device, a separate effervescent material, and instructions relating to the combination of the electronic device and the effervescent material to form cosmetic product.

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 found that by providing an effervescent material and an electronic device, such as a light emitter, in a cosmetic product, the cosmetic effects provided by bath bombs and other effervescent products can be supplemented with sensory effects. Such sensory effects may contribute to the cosmetic wellbeing of the user, and may also enhance the cosmetic effects of the product. The introduction of an electronic device creates a highly appealing multi-sensory effect, with the intention of heightening the visual and olfactory stimulation afforded by the effervescence of the salt of carbonic acid and acidifying agent mixture, by incorporating supplementary visual, aural and tactile stimuli, thus providing enhanced relaxation and therapeutic properties to the user. For example, where the electronic device comprises a component that emits vibration, the cosmetic product may assist in any exfoliating action that the cosmetic product is imparting. Furthermore, such vibration may assist in the breakdown of the cosmetic product when used.

In this regard, the various constituents described herein for the effervescent material may be used to varying extents and in varying amounts in different layers of the effervescent material.

Electronic component

As described above, the cosmetic product of the present invention comprises an electronic component. The electronic component generally comprises an emitter, a power source and electronic circuitry. The emitter is responsible for providing some form of sensory information to the user, such as in the form of light, sound and/or vibrational information. The power source provides power to drive the emitter and the circuitry provides an electronic connection between the emitter and the power source (as well as other optional components of the device).

In one aspect, the emitter is selected from one or more of a light emitter, a sound emitter, and/or a vibration emitter. Preferably, the emitter is a light emitter, such as an LED. The light emitter, preferably an LED, may be capable of emitting a single colour or multiple colours. In one aspect, the light emitter is an RGB LED.

In one aspect, the light emitter is a white LED. Thus, it will be appreciated that although the colour of the light emitter may be white, the effervescent material may be coloured such that the user perceives the light to be coloured (non-white).

In one aspect, the light emitter is of a different colour to the effervescent material. In one aspect, the light emitter is the same colour as the effervescent material.

The electronic device may generally be constructed such that the emitter is only activated in use. In this regard, the electronic device may have a non-activated mode and an activated mode. In the non-activated mode, the emitter does not emit anything perceptible to the user. In the activated mode, the emitter emits perceptible information, such as light, sound and/or vibration to the user.

In one aspect, the electronic device is able to transition back and forth between the activated and the non-activated mode. This transition may be effect via a switch or other suitable means. The switch may be, or comprise, one or more sensors which can be positively actuated by the user and/or which can react to the environmental conditions which are indicative of usage of the cosmetic product.

In one aspect, the one or more sensors are selected from moisture, light, temperature, motion, sound sensors and a combined sensor of any of the aforementioned sensors. Preferably, the sensor is a moisture sensor. For example, in one aspect, the switch comprises a moisture sensor which is capable of detecting changes in moisture in the proximity of the cosmetic product. For example, the moisture sensor may be activated in response to being contacted with water.

In another aspect, where for example the sensor is a temperature sensor, the sensor may be activated by sensing that the temperature in the proximity of the cosmetic product has increased above a threshold level. The threshold level may be set at the typical temperature of a bath, e.g. at or around body temperature.

In one aspect, the sensor is a combined moisture and temperature sensor. Such a sensor may be advantageous as it can be configured to react to being placed in warm water, which might be indicative of a bath. By using such a combined sensor, the risk of inadvertent activation of the electronic device can be mitigated.

In one aspect, sensor, preferably a moisture sensor, is configured to transition the electronic device from the non-activated mode to the activated mode in response to being activated, for example in response to an increase in moisture content being detected by the sensor. It may, however, be desirable for the electronic device to cease emitting information after the cosmetic product has been used. In this regard, the sensor of the electronic device may be configured so as to detect when the cosmetic product has been used. The electronic device may do this by detecting environmental conditions that reflect the end of usage of the cosmetic product, such as a decrease in detected moisture and/or temperature. Therefore, in one aspect, the moisture sensor is configured to transition the electronic device from the non-activated mode to the activated mode in response to an increase in detected moisture, and subsequently to transition the electronic device from the activated mode to the non-activated mode in response to a subsequent decrease in detected moisture content.

In one aspect, the electronic device has a density close to, or less than, that of water such that it will readily float when placed in water. Thus, the electronic device may have a density of about 1.0 gem'³, or less. In one aspect, the electronic device has a density of less than 0.9 gem³. In one aspect, the electronic device has a density of less than 0.8 gem³.

Further, in one aspect the cosmetic product has a density of about 1gcm'³ or less, such as about 0.9 gem’³ or less, such as about 0.8 gem'³ or less.

In some aspects, it may be that the electronic device itself has a different density compared to the cosmetic product as a whole. For example, it may be desirable for the electronic device to become fully submerged once the effervescent material has been exhausted from the cosmetic product. In this regard, the respective densities of the electronic device and the effervescent material could be selected such that the resulting cosmetic product had a density close to that of water (as described above) but the electronic device has a density greater than about 1.0 1gcm'³. Such a product may present the user with different lighting effects at different stages throughout the usage period of the cosmetic product.

The power source will typically be one or more batteries that are able to supply the emitter with appropriate power in order for it to operate. The skilled person will be able to select the appropriate power source depending on the type and size of emitter to be incorporated. However, an exemplary type of power source for use with an LED light source might be one or more CR2032 batteries.

In one aspect the power source may be replaceable and/or rechargeable. This may be advantageous where users wish to return electronic devices to the manufacturer for recycling and/or wish to use the electronic device in a different setting once the effervescent material has been exhausted. For example, where the electronic device comprises a light emitter, it may then be possible to use the resulting electronic device to provide atmospheric lighting in certain settings.

Suitable means of recharging batteries are known, for example, via inductive charging. This may be particularly suitable where the electronic device comprises a completely sealed cover (described below) to protect the electronic components.

The weight of the electronic device is not particularly limited. Rather, it may depend on the intended size of the cosmetic product. However, in one aspect, the electronic component may contribute from about 1 to about 20 wt% based on the cosmetic product.

An example of a suitable electronic device for incorporation into the cosmetic product may be a glowing ice cube, such as available from http://www.glow.co.uk/led-ice-cubes.html.

It will be appreciated that the electronic device will generally comprise a water-proof cover or the like to protect and isolate the internal electronic components from the water. The cover may completely encapsulate/seal the electronic components of the device, or it may allow for the sensor of the device to be exposed. However, such exposure does not lead to the other electronic components being operationally compromised.

Process

In a further aspect, the present invention relates to a process for the production of a cosmetic product as defined herein, comprising the step of combining the electronic device with the effervescent material.

As described above, the effervescent material may envelop the electronic device and as such the process may comprise enveloping the electronic device with the effervescent material (or vice versa).

Additionally, the effervescent material may be caused to solidify in a predetermined shape.
