Natural microspheres from PHA biopolymers for personal care and cosmetic products

Natural microspheres from PHA biopolymers for personal care and cosmetic products

Plastic microbeads are tiny spheres of PP or PE added as abrasives to personal care products like face scrubs, shower gels and toothpaste. They not only wash down the drain, but because of their small size, escape sewage treatment plants, getting discharged into the water bodies. These PE/PP/PET microbeads do not biodegrade, especially in aquatic environments. Also, since they resemble fish eggs, they are likely to be ingested by aqua/ marine life. This, along with increasing consumer demand for environmentally friendly personal care ingredients, is leading to development of several marine biodegradable biopolymers. A few are being discussed:
Metabolix Inc.已与霍尼韦尔(Honeywell)建立了全球独家的商业和技术联盟,以提供新的海洋生物降解生物聚合物,用于化妆品和个人护理产品。通过联盟,将开发Metabolix的Mirel多羟基烷烃(PHA)生物聚合物,作为Honeywell的Asensa个人护理添加剂系列的一部分,这些添加剂用于各种最终用途应用中,从唇膏到湿润的粉末到压粉。使用这些生物聚合物将有助于解决美国待定的立法,致力于取代合成的,不可生物降解的微珠,以及全球对生物基础和可生物降解替代方案的需求。该技术旨在满足全球日益增加的监管和其他要求,以在海洋和淡水环境中生物降解的个人护理微粒。使用适用的ASTM测试方法,这些生物聚合物的海洋生物降解性与纤维素和纸张相似,并且比其他市售可用的可生物降解聚合物更快。Metabolix的产品,Corn Dextrose是该公司目前正在使用的原料。PHA具有与纤维素或纸相似的组成,并且能够比塑料微珠更快地分解成倍分。这些微珠可以在水和土壤中14至18天内生物降解80%。它们吸引了将它们视为食物来源的细菌,从而加快了生物降解过程。微粒也可以堆肥,一旦进入海洋环境,就不会释放有毒物质。

Minerv Bio Cosmetics, the 100% bioplastic has been developed to replace the microbeads in cosmetics that pollute the seas and are now prohibited in many countries. heseMicrobeads由PHA制成,专门为化妆品领域设计。一种新的生物厂工厂将于2018年开始生产。塑料微粒(称为微片)目前用作唇膏,唇彩,睫毛膏,眼睛衬里,指甲油,乳霜,乳霜,乳霜,乳霜,乳霜,乳霜,乳霜,乳霜,乳霜,乳霜,乳霜,乳霜,乳膏,乳霜,乳霜,乳膏,乳膏,奶油,乳膏,奶油,乳霜,稳定剂或稳定剂。洗发水,泡沫浴甚至牙膏污染了环境,因为一旦使用后冲洗,它们就会成为自然循环的永久部分:河流中的浮游生物和海洋吞下这些微观塑料颗粒,从而将它们引入食物链中。污染的水平是如此严重,以至于美国政府已决定提出一项法律(2015年的无微量水域法),禁止在人体护理产品中使用油基聚合物。最近,其他国家遵循了这一决定。
Minerv Pha Bio Cosmetics的化妆品产品中的用途消除了这些污染物,因为生物塑料的微粒颗粒自然可以在水中生物降解,因此不进入食物链。更重要的是,在生物实验室中开发的生物聚合物实际上将自然界中存在的一些微生物和植物分解为营养。因此,对环境的好处是两个方面。Bio-On还发现,在给定的化妆品产品中,Minerv PHA Bio Cosmetics Bioplastic(C1型配方)能够结合活性分子和抗氧化剂,例如辅酶Q10,维生素,蛋白质,蛋白质和活性物质,通常运输它们,运输它们,它们运输它们,它们运输它们,它们运输它们,它们运输它们,它们运输它们,它们是运输它们的,它们自然而然地适用于通常应用化妆品产品的部分。在将其作用的活性物质定位后,生物塑料的微颗粒自然被洗净或吸收而无需痕迹。生物构成生物塑料是由可再生植物来源制成的,其中一些是浪费,没有与食物供应链没有竞争,并且100%天然可生物降解。Bio-On拥有PHA的各个等级生产和使用的整个技术过程,并应用了知识产权业务模型策略。PHA已获得Vincotte和USDA(美国农业部)的认证。发行人的战略设想了PHAS生产和相关辅助服务许可的营销,研发的开发(还通过与大学,研究中心和工业合作伙伴的新合作)以及由Bio-On设计的工厂实现。

In Canada, TerraVerdae BioWorks has announced a line of biodegradable, natural microspheres for use in personal care and cosmetic products, as a direct replacement for synthetic, non-degradable plastic microbeads that are currently the subject of restrictive legislation throughout the world. These natural microspheres are a PHA-based biomaterial produced using a non- GMO, non-toxic, plant-associated process. Unlike other biomaterials that require a compost environment to degrade, they are intrinsically biodegradable and meet the American Society for Testing and Materials (ASTM) industry standards for biodegradation in a marine environment. TerraVerdae can produce microspheres in a range of sizes, in both smooth and coarse finishes, that feature high optical clarity and the mechanical characteristics to meet all requirements for cosmetic formulations.
