FIELD OF THE INVENTION:
The present invention relates to an alcohol free perfumed composition. More particularly, the present invention relates to a water based perfumed composition.

BACKGROUND OF THE INVENTION:
Perfumes carrying fragrance oil typically utilize solvents such as alcohol, high levels of glycols or silicones or in some cases pure oils as perfume carriers. While these ingredients are known to be good solvents for carrying perfume oils for delivery, they suffer from various shortcomings. Further, concerns surrounding such carrier solvents include damage to skin integrity in some cases and highly undesirable sensory manifestations like stickiness or dryness after application in others.

As reported in the art, delivering a stable formulation with hydrophobic ingredients like fragrance oil at high dosages in a water-based system poses a significant challenge.

Known approaches to solving the problem of obtaining stable emulsions with fragrance oil in a water base include use of high levels of glycols and solubilizers (surfactants/detergents) in a relatively high ratio to the oils. Many of such reported systems often employ some anionics as primary surfactant with or without other co-surfactants. However, as is known in the art, use of anionics or cationics surfactants and co-surfactants merely for the sake of oil solubilization is counterproductive since surfactants in these categories unduly increase irritancy.

1488/MUM/2015 and US20030186836A1 disclose ethanol-free, aqua based perfumed compositions that essentially comprise branched fatty alcohols and isoprene glycol as solubilizers/solvents/carriers respectively. However, as a matter of thumb rule, addition of any synthetic ingredients like these not only increases the cost component but also brings its own baggage such as potential skin compatibility issues.

BE1018403A3 discloses an eau de parfum composition comprising a mixture of PEG 20 to 60. However, the eau de parfum also comprises immiscible element, cetearyl octanoate or hexanoic acid, that allows mechanical agitation to integrate with the micro-droplets of the mist and mask the stickiness of the PEG20 to 60.

Water based perfumed compositions in the prior art thus either employ one or more polyols, branched fatty alcohols or similar solubilizing agents to stabilize the compositions. Albeit these ingredients while solving solubilization issue, counterproductively lead to other issues that include high degree of foaming, stickiness on skin due to high relative concentration of surfactants or high degree of skin irritation/compatibility issues. Further, this also adds to the manufacturing cost of the composition.

Accordingly, there exists a need for skin friendly, sensorially superior water based, perfumed composition that comprises substantially minimal amounts of solubilizers in a manner that does not compromise skin-friendliness of the composition.

OBJECT OF THE INVENTION
Accordingly, an object of the present invention is to provide a water based perfumed composition, with substantially high fragrance loading that is substantially free of alcohol and /or silicones.

Another object of the present invention is to provide a sensorially superior, perfumed composition that is substantially free from irritants and ingredients that can cause damage to skin.

Yet another object of the present invention is to provide a water based perfumed composition, with substantially high total oil loading that is substantially free of alcohol and /or silicones.

In one aspect the present invention provides an alcohol-free, water based perfumed composition comprising: a fragrance oil; a solubilizer comprising a first non-ionic surfactant and a second non-ionic surfactant; an emollient oil; a continuous phase;
wherein the ratio of the total oil to total solubilizer is in the range from about 1:0.75 to 1:1.5.

In another aspect the present invention provides a water based perfumed composition is in the form of a spray, characterized in that the spray angle is 60-90 degrees and the viscosity is less than 500 cps.

NW8 demonstrates the criticality of the ratio of total oil to total solubilizes and the ratio of the two solubilizers. It was found that even though the ratio of total oil to total solubilizers is within the working range of the present invention; it was unstable. This instability was on account of the fact that the ratio of tween 20 to PEG 40 Hydrogenated Castor Oil in case of NW1 is 7:1 which is outside the scope of the present invention.

NW9 demonstrates that a single non-ionic solubilizer is unable to provide the desired stability. It was observed that a single non-ionic solubilizer in amount of 7 wt%, could not provide the desired stable formulation. It has been observed by the inventors that at least two different non-ionic solubilizers are essential for obtaining the desired stable formulation. Further, it was observed that one of the non-ionic solubilizers essentially has to be either a Tween (Polysorbate group of surfactants) or PEGylated group of non-ionic surfactant. All the workings examples WE1 to WE8 substantiate this requirement.

NW10 demonstrates that that substitution of one of the non-ionic surfactant with an anionic surfactant such as sodium lauryl sulfate, it resulted in slight creaming of the formulation, a highly undesirable feature when it comes to fragrance compositions since it directly impacts the consumer perception. Further, even such low levels of anionic surfactant (i.e about 1 wt%) was sufficient to illicit harsher tone to the formulation from a skin sensitivity perspective as duly verified through corneo-surfametry.

NW11 demonstrates that inclusion of polymeric agents, especially film forming agents like PVP K 30 in excess of 3wt% resulted in formulations that were too viscous and too sticky thereby being sensorially undesirable.

NW12 demonstrates that higher levels of emollient oils resulted in unstable formulations.

Ratio of total oil to total solubilizers: Table 3 below shows impact on stability of composition upon varied ratio of surfactants to total oil as well as varied ratio between two different non-ionic surfactants that are used as solubilizers. Following add on working examples demonstrate that the operative ratio between the two non-ionic solubilizers is 1:6 to 5:2.

*Fragrance Oil 1 and Fragrance Oil 2 are commercial fragrance oils.

* Stability Profile (Lumisizer Graph)* : Stability of all the compositions in the present specification was tested using lumisizer dispersion analyzer (LUM GmbH) at 3800rpm, at 25 0C for a time period of 12 hours. (Corresponding to 36 months shelf life prediction). The graph profiles generated (using SEPViewTM 6.3.116.7044) during the stability testing method for stable samples did not show any significant particulate movements while unstable samples were characterized by significant particulate movements that later translated to visible separations.

Examples 13 and 20 shows that irrespective of the non-ionic solubilizer used, it is not possible to achieve a stable composition with just a single non-ionic solubilizer. It is therefore essential that at least two different non-ionic-solubilizers be present in the composition to ensure its stability. Examples 1 to 7, 14 to 18 and 21 to 22 show that when two different non-ionic solubilizers are used within the ratio limits of 1:6 to 5:2, they result in stable formulations with fragrance loadings within the inventive limits of the present invention. Examples 8 and 19 also demonstrate that when the ratio of amounts of the two non-ionic solubilizers goes outside the scope of the present invention, it results into unstable formulations.

Table 4 shows that the selection of the supporting emollient oil is one of the determinants of the present invention, given that emollient oils with lower carbon chain fatty acids such as medium chain fatty acid derivatives such as medium chain triglycerides (MCTs) are preferable for generating a stable emulsion system as compared to Long Chain Fatty Acid derivatives.

LCT1 and LCT2 mixtures refer to long chain triglycerides derived from olive oil and almond oil respectively. It was found that chain length of the fatty acid constituents (C16 to C22) in these respective triglycerides were unsuitable as they afforded formulations that were unstable.

Table 5 shows that the choice of surfactants to ensure skin safety is further illustrated wherein through corneosurfametry it has been established that the present formulation comprising non-ionic surfactants such as Polysorbate-20 and PEG-40 Hydrogenated Castor Oil, are gentler on skin compared to the use of anionics such as SLS (Table 3).
