Abstract
本发明涉及一种牙膏,包括研磨剂、保湿剂、起泡剂、增稠剂、香料和水等,采用粒径为15～50μm的微晶纤维素为研磨剂。用微晶纤维素作牙膏研磨剂,能清除牙齿杂质,长期使用能保持牙齿洁白卫生,免遭细菌侵袭,但又不损伤牙齿和口腔组织,尤其对儿童、老人以及缺钙、骨质疏松者更为合适。配制牙膏所用微晶纤维素符合国家标准,不会对人体产生副作用,配制的牙膏对环境友好,是一种理想的新型牙膏。
Description
本发明涉及一种牙膏。
牙膏中通常含有研磨剂、保湿剂、起泡剂、增稠剂、防腐剂、增味剂及其它添加剂和水等，根据不同的用途，可添加着色剂、缓蚀剂、防龋剂、防牙斑剂、抗牙石剂、消炎剂、祛臭剂等。其中的研磨剂常用碳酸钙作原料，清除牙齿附着物和牙菌斑。碳酸钙莫氏硬度3.0，牙齿中牙釉质4.5，牙骨质2～2.5，对比云母1，金刚石10。用在牙膏上的碳酸钙粒径约为30μm时口腔有砂砾感觉，粒径越大，对牙齿的磨损越大，但清洁能力越强。由于碳酸钙的硬度介于牙釉质与牙骨质之间，即使颗粒粒径在10μm左右，常年累月刷牙，牙齿表层牙釉质被磨掉，暴露出牙骨质后，磨损的程度就会更大，最终在牙齿上磨出一道道沟痕，易于被细菌侵袭，出现坏牙、断牙现象，影响咀嚼食物和身体健康。
本发明的目的是在提供一种既能防止牙齿磨损，又能清洁牙齿的新型牙膏。
本发明提供的牙膏，包括研磨剂、保湿剂、起泡剂、增稠剂、防腐剂、甜味剂、香料和水等，采用粒径为15～50μm的微晶纤维素为研磨剂。
其中微晶纤维素的粒径优选15～35μm。
微晶纤维素在牙膏中的含量，按重量百分含量计，优选15～40％。
微晶纤维素由植物纤维经酸水解制成，仍属天然纤维素结构，密度1.50，莫氏硬度小于1，粒径10μm～300μm之间，用于牙膏上约为15～50μm。微晶纤维素吸水率高，吸水后体积膨胀，因而具有弹性。在刷牙过程中，微晶纤维素对牙齿的挤压和摩擦作用，能去除牙齿附着物和牙菌斑，又由于它硬度小，接触牙齿时又有轻微弹性，不损伤牙齿。用放射性牙质磨损法(RDA法)测得放射性牙本质磨损值(RDA值)小于60，通常RDA值在60～100之间足以保持牙齿不受磨损。应该注意到，RDA值测定仅是模型实验，是在刷模型牙4500次后测出的数值。用12μm碳酸钙配制的牙膏RDA值也在60～100之间，这里模型擦牙仅是4500次，继续试验，增加到45000次，含碳酸钙牙膏RDA值＞100，含微晶纤维素牙膏仍小于60，说明它对牙齿基本无磨损。研磨剂在牙膏中的添加量，按重量百分含量计，通常在15～50％之间，采用微晶纤维素为研磨剂，在牙膏中的用量优选15～40％，粒径优选15～35μm。
微晶纤维素来源丰富，可以从棉花、苎麻、木浆等植物纤维中提取，是一种可再生资源。微晶纤维素无毒，可食用，在医药上普遍用作药片赋型剂；也可用作保健食品添加剂，添加在几乎所有食品中去，长期食用能预防便秘和糖尿病、高血压等慢性病发生。用微晶纤维素作牙膏研磨剂，能清除牙齿杂质，长期使用能保持牙齿洁白卫生，免遭细菌侵袭，但又不损伤牙齿和口腔组织，尤其对儿童、老人以及缺钙、骨质疏松者更为合适。由于微晶纤维素性质稳定，又属中性物质，可配制任何类型牙膏；微晶纤维素密度小于碳酸钙，即使所配制的牙膏粘度变小也不会沉淀出来；还能起增稠作用；同是具有良好的能变性和分散性，更符合牙膏产品的性能。碳酸钙能和牙膏中的氟化钠起反应，分解出二氧化碳，易使牙膏爆裂。微晶纤维素可不起反应，它的配伍性能更好。配制牙膏所用微晶纤维素符合国家医药卫生标准，不会对人体产生副作用，配制的牙膏对环境友好，是一种理想的新型牙膏。
实施例
微晶纤维素制法：用2.5N HCl水解棉短绒，棉短绒与酸液浴比为1∶3,95～100℃，水解0.5小时，过滤出微晶纤维素，水洗、碱中和、水洗、烘干、粉碎。过滤得粒径25μm左右的微晶纤维素。按常规配方和方法配制牙膏，去除碳酸钙或其它磨料组份，加入上述微晶纤维素，调整增稠剂(羧甲基纤维素等)用量使粘度达到牙膏生产要求，生产出以微晶纤维素为研磨剂的牙膏产品。
