Description

含有蠟共混物的彩色化妝品組合物Color cosmetic composition containing wax blend

本發明涉及包含蠟的共混物的無水、可塑的化妝品組合物。 The present invention relates to anhydrous, plasticizable cosmetic compositions comprising a blend of waxes.

近年來,存在對於在化妝品組合物中使用矽酮流體的強趨勢。其普及的主要原因是矽酮提供的雅致感:含有它們的產品使皮膚光滑,具有優秀的滑動性,但不產生非矽酮油常常留下的油膩厚重感。矽酮油目前是幾乎所有類型的化妝品組合物(液體和粉末兩者)的常見組分,例如粉底霜、遮瑕膏、眼影和眼線膏、唇膏和唇筆以及腮紅。 In recent years, there has been a strong trend towards the use of silicone fluids in cosmetic compositions. The main reason for their popularity is the elegance that silicones provide: products containing them leave the skin smooth with excellent glide, but without the greasy heaviness that non-silicone oils often leave behind. Silicone oils are now a common component of almost all types of cosmetic compositions (both liquid and powder), such as foundation creams, concealers, eye shadows and eyeliners, lipsticks and lip pencils, and blushers.

矽酮油的另一個有吸引力的方面是它們傾向於在它們所施加的皮膚上產生非常閃亮的外觀。對於某些類型的化妝品,特別是對於針對較年輕的消費者的那些化妝品(對這些消費者而言,鮮明或有光澤的外觀是非常吸引人的),或者對於意圖用於晚間使用的化妝品(其中柔光允許化妝品產生的光澤的更大範圍),這通常是理想的。 Another attractive aspect of silicone oils is that they tend to produce a very shiny appearance on the skin to which they are applied. This is often desirable for certain types of makeup, particularly those targeted at younger consumers (for whom a bright or shiny appearance is very appealing), or for makeup intended for evening use (where a soft glow allows for a greater range of shine produced by the makeup).

然而,對於某些類型的化妝品產品,和/或對於某些類型的消費者,不需要大量的光澤,並且大量的光澤可能甚至是不合適的。較成熟的使用者可能不滿意非常有光澤或發亮的化妝品。表徵較成熟皮膚的細線和皺紋被傾向於直接反射光的有光澤的產品加重。對於某個年齡的消費者而言更優選散射或漫射光的化妝品,從而提供“軟焦點”,其將線模糊並隱藏色斑。在過去實現這類掩蔽的嘗試主要依賴於使用較高水準的顏料,但這經常導致厚重的結塊產品,其不使大部分消費者滿意。 However, for certain types of cosmetic products, and/or for certain types of consumers, a lot of shine is not desired and may even be inappropriate. More mature users may not be satisfied with very glossy or shiny cosmetics. The fine lines and wrinkles that characterize more mature skin are accentuated by glossy products that tend to reflect light directly. Cosmetics that scatter or diffuse light, thereby providing a "soft focus" that blurs lines and hides spots, are more preferred for consumers of a certain age. Attempts in the past to achieve this type of masking have relied primarily on using higher levels of pigment, but this often results in heavy, caked-on products that do not satisfy most consumers.

類似地,也可能僅僅需要消除在某些環境中使用的產品的光澤。例如,有光澤的化妝品在保守的辦公室環境中通常被視為不合適的,和/或在典型辦公室的刺眼光線下可能太耀眼。在這些環境中,對化妝品產品可能需要更加無光澤的裝飾。傳統上,這通過向製劑添加固體粉末,例如雲母、矽石、滑石等實現。然而在基於矽酮油的組合物的情況下,削弱產生的光澤傾向于比較傳統的化妝品油更困難,因此需要添加甚至更大量的固體填充劑。然而,在製劑中較大比例的固體導致在皮膚上厚重的拖曳感,從而在一定程度上抵消矽酮油的一些益處。或者,更加無光澤的外觀可通過在製劑中包括一種或多種揮發性組分,例如水或揮發性油實現;當揮發物在施用後蒸發時,這總體上相對於組合物增加了顏料的濃度,導致更加無光澤的外表。然而,這也可導致在皮膚上乾燥的結塊外表。此外,使用揮發物,特別是水,在所有產品(例如無水唇膏產品) 中是不合適的和/或不可行的,並且還導致需要找到專門的(並且通常昂貴的)氣密包裝以防止揮發物從包裝中的產品損失。 Similarly, it may also be desirable to simply eliminate the shine of a product that is used in certain environments. For example, glossy cosmetics are often viewed as inappropriate in a conservative office environment and/or may be too dazzling in the harsh lighting of a typical office. In these environments, a more matte finish may be desired for a cosmetic product. Traditionally, this has been achieved by adding solid powders, such as mica, silica, talc, etc., to the formulation. However, in the case of compositions based on silicone oils, it tends to be more difficult to attenuate the shine produced than with conventional cosmetic oils, and therefore even greater amounts of solid fillers need to be added. However, a larger proportion of solids in the formulation results in a heavy dragging sensation on the skin, thereby offsetting some of the benefits of silicone oils to a certain extent. Alternatively, a more matte appearance can be achieved by including one or more volatile components in the formulation, such as water or volatile oils; when the volatiles evaporate after application, this generally increases the concentration of the pigment relative to the composition, resulting in a more matte appearance. However, this can also result in a dry, caked appearance on the skin. Furthermore, the use of volatiles, especially water, is not suitable and/or feasible in all products (such as anhydrous lipstick products), and also results in the need to find specialized (and often expensive) airtight packaging to prevent loss of volatiles from the product in the packaging.

根據以上內容,一直需要化妝品組合物,其可遞送優秀的收效(payoff)和美學效應而沒有當包括高水準的固體時現有製劑顯示的讓人不愉快的感覺的缺點。 In light of the above, there continues to be a need for cosmetic compositions that deliver excellent payoff and aesthetic effects without the unpleasant sensory drawbacks exhibited by existing formulations when high levels of solids are included.

本發明涉及包含蠟的共混物的無水、可塑的化妝品組合物。蠟共混物包括至少四種不同的蠟,各自特徵為分別具有約60℃至約65℃;約33℃至約46℃;約88℃至約96℃;和約74℃至約99℃的熔化溫度。所述組合物進一步包括至少一種溶劑,其優選是非揮發性的溶劑;和至少一種顏料。 The present invention relates to an anhydrous, plastic cosmetic composition comprising a blend of waxes.

非限制性實施例 Non-limiting embodiments

以下實施例中舉例說明的組合物闡明了本發明的組合物的特定實施方案,但不意圖對其進行限制。在不脫離本發明的精神和範圍的情況下,技術人員可進行其它修改。舉例說明的實施方案1-5提供了可塑的無水化妝品組合物,具有高顏料負載。實施例6-9是不能顯示可接受的化妝品性能的配方的比較性說明,如下文更詳細論述的。 The compositions illustrated in the following examples illustrate specific embodiments of the compositions of the present invention, but are not intended to be limiting thereof. Other modifications may be made by a skilled artisan without departing from the spirit and scope of the present invention. The illustrated embodiments 1-5 provide plastic anhydrous cosmetic compositions with high pigment loading. Examples 6-9 are comparative illustrations of formulations that fail to exhibit acceptable cosmetic performance, as discussed in more detail below.

根據以下實施例的組合物可根據以下步驟製備:首先,將合成蜂蠟與微晶蠟和硬脂基二甲矽油/十八碳烯的每一種在容器中混合,將其加熱至約95℃以形成第一相。接著,在單獨的燒杯中,在約95℃下合併除了顏料和顆粒(雲母)的所有剩餘的成分以形成第二相。接著,合併第一相和第二相以形成單一混合物,保持約95℃的混合溫度。最後,加入顏料和顆粒至混合物中。混合直到各成分形成均勻的組合物,然後停止混合並允許混合物冷卻至室溫。 The composition according to the following embodiment can be prepared according to the following steps: First, synthetic beeswax is mixed with each of microcrystalline wax and stearyl dimethicone/octadecene in a container, which is heated to about 95°C to form a first phase. Then, in a separate beaker, all remaining ingredients except pigment and particles (mica) are combined at about 95°C to form a second phase. Then, the first phase and the second phase are combined to form a single mixture, maintaining a mixing temperature of about 95°C. Finally, the pigment and particles are added to the mixture. Mix until the ingredients form a uniform composition, then stop mixing and allow the mixture to cool to room temperature.

所有例舉的量作為重量百分比列出,並且不包括次要材料,例如稀釋劑、防腐劑、著色溶液、成象成分、植物材料等,除非另外指明。 All exemplified amounts are listed as weight percent and do not include minor materials such as diluents, preservatives, coloring solutions, imaging components, plant materials, etc. unless otherwise specified.

以下代表了本發明的化妝品組合物:

The following represents the cosmetic composition of the present invention:
Figure 109110698-A0305-02-0018-1

下表2說明了在表1提供的實施例中的比較性化妝品性能。觀察每個示例性的實施方案並評價其作為化妝品組合物的合適性。首先,評價組合物的可加工性。組合物必須具有良好的混合和傾倒性能。第二,在加工步驟後觀察產品,並評價它的拖曳、收效(payoff)、可塑性和感覺特徵。本文使用的術語“拖曳”是指產品施加到皮膚上的相對容易性。在感覺方面,具有低拖曳的產品感覺出在皮膚上滑動。相比之下,具有增加的拖曳的產品將顯示摩擦和不均勻施加到皮膚。本文使用的術語“收效”是指化妝品組合物當施加到皮膚時的顏色強度。感覺出更強烈的顏色強度與較高的相對收效有關,和感覺出較不強烈的顏色強度與較低的相對收效有關。 Table 2 below illustrates comparative cosmetic performance in the examples provided in Table 1. Each exemplary embodiment was observed and evaluated for its suitability as a cosmetic composition. First, the processability of the composition was evaluated. The composition must have good mixing and pouring properties. Second, the product was observed after the processing steps and evaluated for its drag, payoff, plasticity, and feel characteristics. The term "drag" as used herein refers to the relative ease with which a product is applied to the skin. In terms of feel, products with low drag feel like they slide on the skin. In contrast, products with increased drag will show friction and uneven application to the skin. The term "payoff" as used herein refers to the color intensity of the cosmetic composition when applied to the skin. A more intense perceived color intensity is associated with a higher relative yield, and a less intense perceived color intensity is associated with a lower relative yield.

本文公開的尺寸和值不應理解為嚴格限制所述的準確 數值。而是,除非另外指明,每個這樣的尺寸意圖指所述值和圍繞該值的功能等同範圍。例如,公開為“40mm”的尺寸意圖指“約40mm”。 The dimensions and values disclosed herein should not be construed as strictly limited to the exact numerical values recited. Rather, unless otherwise specified, each such dimension is intended to refer to the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as "40 mm" is intended to mean "approximately 40 mm."
