[0005] However, a common disadvantage of tube mascaras is that they are difficult to build up in layers to Achieve a volumized look
Techniques discussed in the art for achieving a volumizing look with tube mascaras include the use of sideways application (see, George, Jenn "Tubing mascaras: The smudge-free formulas that dreams are made of', Glamor, 11 April 2018), but In practice, this is difficult to do without forming cliques
Another technique involves using pencil eyeliner in combination with tube mascara (see, "L'Oreal Beauty Magazine "How to Use Tubing Mascara", retrieved from https: / / www.lorealparisusa.com / beauty-magazine / makeup / eye-makeup / how-to-use-tubing-mascara.aspx, accessed September 13, 2018"), but this involves using multiple products, which is more inconvenient and difficult to do in practice

Embodiment 1
[0080] Example 1 - Mascara Formulation
[0081] Three comparative mascara formulations (CE1, CE2 and CE3) and one inventive mascara formulation (IE) were batch-produced. The key components of these formulations are presented in Table 1 below:
[0082]
[0083] Table 1
[0084] The above mascara formulations were made using the following method:
[0085] 1) In a supporting container, heat the waxes (white beeswax, carnauba wax, hard paraffin wax, and candelilla wax) and emulsifiers (cetearyl alcohol and steareth-21) to between 80°C and 85°C. time until all the wax is melted;
[0086] 2) In the main container, disperse sequestrene tetrasodium in water by manual stirring;
[0087] 3) Mix the PPG-17 / IPDI / DMPA copolymer into the main container by manual stirring until the solution is uniform;
[0088] 4) Use a homogenizer to mix black iron oxide C33-7001 into the main container at a speed of 4000rpm until homogenization is completed;
[0089] 5) Use a homogenizer to mix ...
Embodiment 2
[0100] Example 2 - Expert Study
[0101] method
[0102] Nine female volunteers, who were considered knowledgeable about the types of mascaras available commercially and how to apply them, were asked to test mascara formulations CE3 and IE. Volunteers were asked to apply three coats of a mascara formulation, where it was necessary to re-dip the mascara brush into the package to reload the applicator in order to apply the second and third coats. Volunteers were informed that they could make as many "sweeps," which are strokes of the applicator over the lashes, as they wished, without reloading the applicator. Volunteers were then asked to rate whether mascara smudged after splashing their faces with cold water. Volunteers were then asked to remove the mascara application by applying warm water to the lashes several times for two minutes followed by either (i) wiping off the application with gentle pressure using a cotton make-up remover pad or (ii) pulling off using fingert...
Embodiment 3
[0109] Example 3 - User Experimental Research
[0110] method
[0111] Thirty one female volunteers between the ages of 18 and 55 were asked to test mascara formulations CE1, CE2 and IE. All volunteers tested in the study were daily mascara users and preferred the volumized look. As in Example 2, volunteers were asked to apply three coats of a mascara formulation, where it was necessary to re-dip the mascara brush into the package to reload the applicator in order to apply the second and third coats . As above, volunteers were informed that they could take as many "sweeps," which are strokes of the applicator up the lashes, as they wished, without reloading the applicator. The volunteers were then asked to wear the mascara application for at least 24 hours, and for a portion of this duration of application they would need to experience sweating and / or a humid environment to adequately test the long-wear properties of the mascara formulation. As above, volunteers were the...

Abstract
According to the present invention there is provided a stable, fluid, tubing mascara composition in the form of an oil-in-water emulsion comprising: (i) at least 9% by weight of the total composition of one or more film-forming aliphatic polyurethane resins; and (ii) one or more waxes; wherein the ratio of total aliphatic polyurethane resin concentration to total wax concentration is between 0.70 and 0.92. The present invention also provides an assembly or kit for packaging and applying a mascara composition for coating eyelashes, comprising: (i) a device for packaging the mascara composition as defined above; and (ii) an applicator for the composition. The present invention also provides a method using the assembly or kit as defined above for building up layers of the mascara composition onto the eyelashes comprising: (i) applying the mascara composition to the applicator; (ii) moving the applicator so that the mascara composition is applied to the eyelashes from the roots of the eyelashes to the tips of the eyelashes; (iii) optionally repeating (ii) in order to apply an even coat of the mascara composition onto the eyelashes; and (iv) optionally repeating steps (i) to (iii), wherein subsequent reapplications of the mascara compositions are carried out whilst the mascara composition present on the eyelashes has not yet dried.
Description
technical field [0001] The present invention relates to novel stable fluid tube mascara compositions which are buildable to provide a volumizing cosmetic effect. Background technique [0002] Consumers continue to demand long-wearing color cosmetics, with 'long-lasting' being the most frequently requested request in the color cosmetics category in 2016 and 2017, according to Mintel. Consumers increasingly desire cosmetics that last throughout the day without reapplication and can be worn in wet conditions or during exercise. [0003] With regard to mascara cosmetics, conventional mascaras tend to lack the ability to adequately remain on the eyelashes if subjected to external forces such as friction or water. Furthermore, if the formulation separates from the lashes, these mascaras often smudge on the user's face, leaving a detracting "panda eye" appearance. Attempts to solve such problems have resulted in mascaras that do not provide the desired thickening effect or that b...
