AI Technical Summary
There is a need for high-quality hydrophobic powders made from renewable sources or natural-derived products, as existing solutions fail to effectively provide hydrophobicity while being environmentally friendly and cosmetically appealing.
A powdered composition is developed by surface-treating a substrate with a Moringa component, such as Moringa oleifera seed extract, oil, or butter, and optionally including an antioxidant, to create a hydrophobic powder suitable for cosmetic applications.
The resulting hydrophobic powders exhibit excellent dispersibility, oxidative stability, and a soft, creamy skin feel, making them suitable for a wide range of cosmetic products while being environmentally friendly.

[0001] CROSS-REFERENCE TO RELATED APPLICATION
[0002] Not applicable.BACKGROUND
[0003] In recent years there has been an increasing demand to use natural products from renewable sources or natural derived products in the field of cosmetics. Natural surface treatment of the pigments with a clean label, appealing story, and sustainable beauty claims is increasingly popular. In one example, hydrogenated lecithin treatment provides a nutritious effect and excellent affinity to the skin. In another example, jojoba ester treatment is stable at high temperature, has oxidative stability, and provides moisturization to dry skin, see US Patent No. 8, 623, 386, herein incorporated by reference in its entirety. Further, stearoyl glutamic acid allows pigment to be easily dispersed in an anhydrous system. Coco aloe treatment also provides good dispersibility.
[0004] However, high quality hydrophobic powders that are made from renewable sources or natural derived products remain evasive and a need exists for new renewable or natural derived powdered compositions exhibiting hydrophobicity.SUMMARY

The substrate is a particulate having a surface that is neither substantially hydrophobic nor substantially hydrophilic. In an embodiment, the substrate is a particulate having a surface that is neither hydrophobic nor hydrophilic. The surface treated powder is substantially hydrophobic. In an embodiment, the surface treated powder is hydrophobic. The surface treatment can include a Moringa component and an antioxidant. The Moringa component is selected from the group consisting of a Moringa oleifera seed extract, a Moringa seed extract, a Moringa oil, a Moringa oleifera oil, a Moringa seed oil, a Moringa oleifera seed oil, a hydrogenated Moringa oil, a hydrogenated Moringa oleifera oil, a Moringa ester, a Moringa oleifera ester, a Moringa butter, a Moringa oleifera butter, and any combinations thereof.
[0006] In another embodiment, the present disclosure provides a method of making a powdered composition.

[0027] The current disclosure demonstrates that different sources of natural oil and natural surface treatment can not only provide easy dispersibility and good oxidative stability without odor, but also provide the very nice soft creamy texture on the skin and in cosmetic applications. Combining with natural oil, ester or butter to get natural surface treated powders, in particular pigments is the first reported in this field with unique soft and creamy skin feeling in the cosmetic application, especially in loose powder and compact powder, and easily dispersible in many oil systems with high pigment loading.
[0028] Based on the present disclosure, natural oil, ester, or butter, a Moringa oleifera seed extract, a Moringa seed extract, a Moringa oil, a Moringa oleifera oil, a Moringa seed oil, a Moringa oleifera seed oil, a hydrogenated Moringa oil, a hydrogenated Moringa oleifera oil, a Moringa ester, a Moringa oleifera ester, a Moringa butter, a Moringa oleifera butter, and any combinations thereof, are employed as a surface treatment on powders. The obtained powders are hydrophobic and have a unique soft and creamy skin feeling in the cosmetic application, especially in loose powder and compact powder. The treated powders of the present disclosure are applied in a wide range of cosmetic compositions.
[0029] This new natural surface treatment with Moringa oil, Moringa ester, or Moringa butter from different sources on different powders, not only provides easy dispersibility with high pigment loading and good oxidative stability without an odor issue, but also provides the very nice soft creamy texture on skin and in cosmetic applications.
[0030] There is therefore an interest in providing a new, improved powder treatment.
[0031] An embodiment of the present disclosure is to provide a new natural treatment of powders, with good hydrophobicity and good compatibility with a wide range of cosmetic oils, and allow providing a dispersion with increased dispersibility and higher pigment load.
[0032] An embodiment of the present disclosure is to provide a new natural treatment of powders, in particular pigments, making it possible to improve their dispersion with unique soft and creamy skin feeling with reduced or no odor, in particular in loose powder and compact powder cosmetic applications, in particular with the cosmetic compositions, which is more respectful of the environment and implements bio-sourced compounds that allow the treatment of powders of all sizes.
[0033] Another embodiment of the present disclosure is to provide a method of treatment that is fast and consumes less energy than current methods and is therefore more environmentally friendly than current methods.
[0034] Some of these advantages are fulfilled by the present disclosure which relates to a composition, in powder form, comprising:
[0035] A powder, in particular a pigment, a mineral filler or powder, a polymer, alone or as a mixture; 0%to 10%by weight of aluminum hydroxide to the total weight to weight of the composition; 1%to 20%by weight of Moringa oil or 1%to 20%by weight of Moringa ester, or 1%to 20%by weight of Moringa butter, preferably 4%to 10%by weight of Moringa ester, or 1%to 20%by weight of Moringa butter relative to the total weight of the composition. In some cases, the Moringa component is present in the composition in an amount by weight of at least 1%, at least 2%, at least 3%, at least 4%or at least 5%. In some cases, the Moringa component is present in the powdered composition in an amount by weight of at most 20%, at most 17%, at most 15%, at most 13%, at most 10%, at most 9%, at most 8%, at most 7.5%, or at most 5%.

[0044] Another embodiment of the present disclosure is a process for preparing a natural surface treated powder mixture through blending the pigment / powder with a natural oil, ester, or butter, or any combination thereof, with heating the blend to between 40 ℃ and 80 ℃, preferably to between 50 ℃ and to 70 ℃; and allowing the blend to cool to room temperature. The process may also include the micronization step after drying or grinding, depending on the nature of the powder.
[0045] Hydrophobicity of the powders described herein can be measured in a variety of ways, but one particular process was used throughout the examples articulated below and which gives a relatively quick and straightforward binary answer as to hydrophobicity. In one aspect, hydrophobicity can be shown by attempting to mix the powder with water and being met with the powder refusing to mix with the water and floating on the surface (or otherwise gathering at an interface) . In one specific example, 200 mL of water is introduced into a 250 mL bottle and 1g of a powder is added (e.g. the Example and Comparative Example powders below) , then the bottle is closed and shaken vigorously. If the pigment does not wet and floats on the surface for 12 hours, it is denoted as a good hydrophobicity and is given a grade of “A” . If the pigment is wet completely, the hydrophobicity is null hydrophobicity and is given a grade of “B” .
