Coated particles of metal (such as calcium) silicate that exhibit excellent odor neutralization and sebum absorption properties when present within certain cosmetic and/or personal care formulations and suspensions are provided. Uncoated calcium silicate exhibits a high pH level that may have a deleterious effect upon such cosmetic and/or personal care compositions, thereby rendering the overall composition ineffective for its intended purpose, particularly if the calcium silicate is present in its usual state at high loading levels. Alternatively, if certain materials present within personal care compositions exhibit a sufficiently low pH level, the effectiveness of such calcium silicates may be compromised as well. Such novel coated/treated calcium silicates thus permit high loadings of this beneficial odor neutralizing/sebum absorbing additive within cosmetic and/or personal care formulations without causing any appreciable instability issues or viscosity modification concerns or allow for coexistence with such low pH materials without any appreciable reduction in performance capabilities of the calcium silicates themselves. Certain personal care compositions comprising these novel coated calcium silicate particulates are encompassed within this invention as well.
本发明提供了
金属(如
钙)
硅酸盐的涂层颗粒,当存在于某些化妆品和/或个人护理配方和悬浮液中时,表现出优异的气味中和和皮脂吸收性能。未涂层的
硅酸钙表现出高pH值,可能对这些化妆品和/或个人护理组合物产生有害影响,从而使整个组合物对其预期用途无效,特别是如果
硅酸钙以高负荷
水平存在于其通常状态下。或者,如果个人护理配方中存在某些材料表现出足够低的pH值,这些
硅酸钙的有效性也可能受到损害。因此,这种新型涂层/处理的
硅酸钙允许高负荷这种有益的气味中和/皮脂吸收添加剂存在于化妆品和/或个人护理配方中,而不会引起任何明显的不稳定性问题或黏度修改问题,或者允许与这些低pH材料共存,而不会对
硅酸钙本身的性能产生任何明显的降低。本发明还包括某些包含这些新型涂层
硅酸钙颗粒的个人护理配方。
