The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments of the present invention.
Reference will now be made in detail to certain embodiments of the disclosed subject matter, examples of which are illustrated in part in the accompanying drawings. While the disclosed subject matter will be described in conjunction with the enumerated claims, it will be understood that the exemplified subject matter is not intended to limit the claims to the disclosed subject matter.
Throughout this document, values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. For example, a range of “about 0.1% to about 5%” or “about 0.1% to 5%” should be interpreted to include not just about 0.1% to about 5%, but also the individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1% to 0.5%, 1.1% to 2.2%, 3.3% to 4.4%) within the indicated range. The statement “about X to Y” has the same meaning as “about X to about Y,” unless indicated otherwise. Likewise, the statement “about X, Y, or about Z” has the same meaning as “about X, about Y, or about Z,” unless indicated otherwise.
In this document, the terms “a,” “an,” or “the” are used to include one or more than one unless the context clearly dictates otherwise. The term “or” is used to refer to a nonexclusive “or” unless otherwise indicated. The statement “at least one of A and B” or “at least one of A or B” has the same meaning as “A, B, or A and B.” In addition, it is to be understood that the phraseology or terminology employed herein, and not otherwise defined, is for the purpose of description only and not of limitation. Any use of section headings is intended to aid reading of the document and is not to be interpreted as limiting; information that is relevant to a section heading may occur within or outside of that particular section. All publications, patents, and patent documents referred to in this document are incorporated by reference herein in their entirety, as though individually incorporated by reference. In the event of inconsistent usages between this document and those documents so incorporated by reference, the usage in the incorporated reference should be considered supplementary to that of this document; for irreconcilable inconsistencies, the usage in this document controls.
In the methods described herein, the acts can be carried out in any order without departing from the principles of the invention, except when a temporal or operational sequence is explicitly recited. Furthermore, specified acts can be carried out concurrently unless explicit claim language recites that they be carried out separately. For example, a claimed act of doing X and a claimed act of doing Y can be conducted simultaneously within a single operation, and the resulting process will fall within the literal scope of the claimed process.
The term “about” as used herein can allow for a degree of variability in a value or range, for example, within 10%, within 5%, or within 1% of a stated value or of a stated limit of a range, and includes the exact stated value or range. The term “substantially” as used herein refers to a majority of, or mostly, as in at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 99.99%, or at least about 99.999% or more, or 100%. The term “substantially free of” as used herein can mean having none or having a trivial amount of, such that the amount of material present does not affect the material properties of the composition including the material, such that about 0 wt % to about 5 wt % of the composition is the material, or about 0 wt % to about 1 wt %, or about 5 wt % or less, or less than or equal to about 4.5 wt %, 4, 3.5, 3, 2.5, 2, 1.5, 1, 0.9, 0.8, 0.7, 0.6, 0.5, 0.4, 0.3, 0.2, 0.1, 0.01, or about 0.001 wt % or less, or about 0 wt %.
The polymers described herein can terminate in any suitable way. In some embodiments, the polymers can terminate with an end group that is independently chosen from a suitable polymerization initiator, —H, —OH, a substituted or unsubstituted (C1-C20)hydrocarbyl (e.g., (C1-C10)alkyl or (C6-C20)aryl) interrupted with 0, 1, 2, or 3 groups independently selected from —O—, substituted or unsubstituted —NH—, and —S—, a poly(substituted or unsubstituted (C1-C20)hydrocarbyloxy), and a poly(substituted or unsubstituted (C1-C20)hydrocarbylamino).

Mascaras with the composition according to the invention may exist as O/W or W/O emulsions. Suitable emulsifiers for O/W emulsions are for instance addition products of 2-30 mol ethylene oxide to linear C8-C22 fatty alcohols, to C12-C22 fatty acids and to C8-C15 alkylphenols; C12-C22 fatty acid monoesters and diesters of addition products of 1-30 mol ethylene oxide to glycerine.
For W/O emulsions it is preferred to incorporate the emulsifier at a different step after the above mentioned complex is formed. Copolymers of polysiloxane polyalkyl polyethers are possible emulsifiers. A suitable emulsifier is Cetyl Dimethicone Copolyol.
In some examples, the mascara composition can include the components listed in Table 1. As shown in Table 1, the mascara composition includes a plurality of stages that are ultimately mixed together to form the mascara composition. Wt % ranges listed in Table 1 for each component are relative to the entire mascara composition.
An additional example of a suitable mascara composition is shown in Table 2. The formulation of Table 2 differs from that of Table 1 in that some materials that are “plastic” are removed and replaced with more biodegradable materials such as Organsol 4000 EX™.
The mascara compositions described herein are capable of rapid drying. For example, the mascara composition can dry within a range of from about 1 minute to about 10 minutes following application to an eyelash, about 3 minutes to about 7 minutes, less than, equal to, or greater than about 1 minute, 2, 3, 4, 5, 6, 7, 8, 9, or about 10 minutes. Additionally, the mascara composition can visibly lengthen the appearance of an eyelash in a range of from about 20% to about 200%, relative to a baseline eyelash that is free of the mascara, about 30% to about 50%, less than, equal to, or greater than about 20%, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, 170, 175, 180, 185, 190, 195, or about 200%. Further, the mascara composition can visibly increase the volume of an eyelash in a range of from about 5× to about 15×, relative to a baseline eyelash that is free of the mascara, about 6× to about 10×, less than, equal to, or greater than about 5×, 6×, 7×, 8×, 9×, 10×, 11×, 12×, 13×, 14×, or about 15×.
The mascara composition can be a component of a mascara kit. The mascara kit can include a vessel into which the mascara composition is deposited. The kit can further include an applicator such as a brush or wand that is removably disposed at least partially within the vessel. The brush or wand can have a micro brush head, a bubble brush head, a pointed hourglass cone head, an oversized head, a cone taper head, a curved head, a balled tip head, a microwand head, a tuber shorty head, or a flat comb head.
The mascara composition can be made according to any suitable method. According to some examples, the mascara composition can be formed by processing the polyacrylate component, the polyvinylpryrrollidone component, the acrylate copolymer component, the acrylic acid copolymer component, the eicosene copolymer component, the structurant component, and the fiber component.
According to further embodiments, individual stages (such as those identified in Table 1) can be individually fed into a homogenizer to ultimately form the mascara composition. Individual stages may be heated to a temperature suitable to bring several or all components of the stage to a liquid phase before being fed into the homogenizer. The environment within the homogenizer can be kept at a predetermined temperature or the temperature can vary. The homogenizer may include a rotating element such as a blade or paddle to mix the components. The degree to which the rotating element rotates can be controlled to be constant or variable during the course of manufacturing the mascara composition.
Various embodiments of the present invention can be better understood by reference to the following Examples which are offered by way of illustration. The present invention is not limited to the Examples given herein.
Various properties of the described mascara composition were determined according to the below Example.
Mascaras tested included Composition 1, Composition 2, Comparative Composition 1, and Comparative Composition 2.
Three different mascara wands were used to apply the respective mascara compositions to an individual tester's eyelash. The brushes are named “Mini Cashmere”, “Burgundy”, and “Grey Flower”. Details on each wand are provided below in Table 4. Comparative Compositions 1 and 2 used a hard plastic brush.
To test the mascara compositions, a sensory panel was established. The sensory panel included a total of 11 trained expert female panelists. The ages ranged from 38-68 years old. Each panelist had 3 years of experience in evaluating beauty care products.
Descriptive analysis approach was used to understand various mascara sensory attributes and the degree to which these attributes vary between the mascara samples. Panelists were given a training on various mascara sensory attributes (Initial texture, brush load, application and lash feel). An attribute list was generated after consulting with the project lead team member and the list was further discussed with panelists for attribute concept alignment and consensus. Attribute intensity was measured on a 0(None)-10(High) continuous linear line scale. Samples were presented in sequential monadic pattern over 3 sessions. In each session panelists applied one product for both eyes and evaluated various sensory attributes.
Each panelist applied the respect mascara composition with 15 strokes of the mascara compositions to top lashes of the left eye. The brush was re-dipped. Then 15 strokes of the mascara composition was applied to the top lashes on the right eye. Then the brush was re-dipped. Then 15 strokes of the mascara compositions were applied to top lashes of the left eye. The brush was re-dipped. Then 15 strokes of the mascara composition was applied to the top lashes on the right eye. The panelist then waited 5 minutes and took a picture of their eye and evaluated the result on a scale of 1-10 based on a ballot, the options of which are listed below in Table 5. Furthermore, each panelist took a picture of eyelash without having any mascara applied, this was designated as a baseline eyelash.
Evaluation of key sensory attributes between an untreated (baseline) eyelash as well as eyelashes treated with Composition 1, Comparative Composition 1, Comparative Composition 2, and Comparative Composition 3 are presented, in part, in
Table 8 shows the average values assigned by the sensory panel for the lash length attribute.
Table 9 shows the average values assigned by the sensory panel for the lash volume attribute.
Table 10 shows the average values assigned by the sensory panel for the lash curl attribute.
Table 11 shows the average values assigned by the sensory panel for the lash lift attribute.
Average perceived dryness at time points following application of 1 minute, 2 minutes, 3, minutes, 4 minutes, and 5 minutes are presented in
