Definitions

  • the present application relates to the technical field of fast-dissolving particles, and in particular to a hyaluronate that can be quickly dispersed and dissolved and a preparation method thereof.
  • the hyaluronic acid (HA) molecule is an anionic linear macromolecular polysaccharide composed of regular alternating residues of D-glucuronic acid and N-acetyl-D-glucosamine.
  • the amino sugar is linked to D-glucuronic acid through a ⁇ -(1-4)-glycosidic bond
  • the glucuronic acid is linked through a ⁇ -(1-3)-glycosidic bond.
  • the carboxyl groups of HA are dissociated and the polymer molecules have a high density of negative charges, which attract sodium, potassium, magnesium, calcium and other osmotically active cations. Because of this, HA can bind 1000 times more water than the weight of the macromolecule itself. Due to these physicochemical properties, HA molecules can form gels even at very low concentrations.
  • Hyaluronate is a high molecular polymer with strong lubricity and film-forming properties, and is highly viscous. It tends to clump when dissolved in water, and once it clumps, it becomes difficult to dissolve.
  • measures such as slowing down the feed rate, increasing the solution temperature and stirring speed are generally adopted to solve the problem, or adding additives such as sugar alcohols to dry or wet granulate.
  • the former increases production energy consumption and costs, while the latter introduces other ingredients and actually produces a mixture containing hyaluronate, which reduces the concentration of hyaluronate and limits the scope of use of hyaluronic acid, especially in the fields of medicine and equipment, making it difficult to comply with regulations for use.
  • HA is widely used in clinical medicine and cosmetics production.

Description

可快速分散和溶解的透明质酸盐及其制备方法 技术领域
本申请涉及速溶颗粒技术领域,尤其涉及一种可快速分散和溶解的透明质酸盐及其制备方法。
背景技术
透明质酸(HA)分子是由D-葡萄糖醛酸和N-乙酰-D-葡萄糖氨基的规则交替残基组成的阴离子线性大分子多糖,在透明质酸分子中,氨基糖通过β-(1-4)-糖苷键与D-葡萄糖醛酸相连,葡萄糖醛酸通过β-(1-3)-糖苷键相连。在pH值约为7.0的条件下,HA的羧基被解离,聚合物分子具有高密度的负电荷,它们吸引钠、钾、镁、钙和其他具有渗透活性阳离子。正因为如此,HA可以结合比大分子本身的重量多1000倍的水,由于这些物理化学性质,HA分子即使在非常低的浓度下也能形成凝胶。
透明质酸盐属于高分子聚合物,具有很强的润滑感和成膜性,且具有高黏性,在水中溶解时存在抱团现象,一旦成团会造成溶解困难,在工业生产中,为了缩短其溶解时间,一般采用放缓投料速度,增加溶液的温度和搅拌速度等措施来解决,或者采用加入糖醇等助剂干法或者湿法制粒的方式,前者增加了生产能耗及成本,后者则引入了其他成分,实际产出了含有透明质酸盐的混合物,降低了透明质酸盐的浓度,限制了透明质酸的使用范围,尤其在医药和器械领域,很难符合法规投入使用。
HA被广泛应用于临床医学和化妆品生产等领域。随着2021年HA被批准为新资源食品原料,HA的应用领域不断扩大,对HA原料的需求不断扩大,工业化制备高品质、易分散、可快速溶解的HA更具价值。
目前常用的制粒工艺包括湿法挤压/剪切制粒、湿法混合制粒、干法制粒、沸腾制粒。前3种制粒方法所得到的HA颗粒属于紧实性颗粒,堆积密度大,特别是大分子透明质酸盐,仍无法解决在水中溶解成团聚集的问题,分散性及溶解速度的改善非常有限。
中国专利申请CN 115363163A公开了一种速溶透明质酸钠颗粒及其制 备方法,所述制备方法包括如下步骤:(1)取原料透明质酸钠粉末,加入预先粉碎过筛的辅料糖醇,混合均匀,得混合物;(2)将步骤(1)所述混合物置于沸腾制粒机内,采用顶喷的方式,将粘合剂溶液喷入,调节雾化器压力及物料温度,制成24~65目筛之间的均匀颗粒,即得速溶透明质酸钠颗粒。该方法获得的速溶透明质酸钠颗粒中引入了其他辅料成分,不能得到100%透明质酸钠成分。
中国专利申请CN 109851822A公开了一种速溶透明质酸钠的制备方法:取透明质酸钠粉末加水溶解为透明质酸钠溶液;再加入氯化钠;通过乙醇沉淀透明质酸钠;然后通过剪切乳化至静置30min无分层;再进行固液分离,然后将固体脱水后干燥;然后依次经过锤式粉碎机和超微粉碎机粉碎,获得速溶透明质酸钠粉末。该方法的制备工艺复杂,且引入了其他成分,不能得到100%透明质酸钠成分。

本申请提供了一种可快速分散和溶解的透明质酸盐,其通过上述所述的方法制备得到。
本申请提供了乙醇水溶液在制备可快速分散和溶解的透明质酸或其盐中的用途。
在一些实施方式中,所述乙醇水溶液中乙醇的浓度为8-70wt%。
例如所述乙醇水溶液中乙醇的浓度可以为8wt%、10wt%、15wt%、20wt%、25wt%、30wt%、35wt%、40wt%、45wt%、50wt%、55wt%、60wt%、65wt%、70wt%等。
实施例
本申请对试验中所用到的材料以及试验方法进行一般性和/或具体的描述,在下面的实施例中,如果无其他特别的说明,%表示wt%,即重量百分数。所用试剂或仪器未注明生产厂商者,均为可以通过市购获得的常规试剂产品。
实施例1粘合剂以及原料和粘合剂比例的研究以及溶解性的研究
(1)制粒研究
将1kg分子量为1500k Da的透明质酸钠粉末加入FBM-3型沸腾制粒机(设备容量为3L)中,分别以30wt%含乙醇的水溶液和1‰羧甲基纤维素钠作为粘合剂,从沸腾制粒机的顶部喷入,沸腾制粒机的雾化压力为0.1MPa, 进风温度60℃,物料温度为43℃,处理84min后使用20目和60目的筛网进行筛选得到介于20目到60目之间的透明质酸钠颗粒,其中,透明质酸粉末和粘合剂的质量比例如表1所示,其中,经测试,采用1‰羧甲基纤维素钠作为粘合剂的6-10组制粒失败,收率不足10%,最重要的是,在制粒过程中,喷枪多次被黏阻,堵塞,在多次工艺中断、人工清理下完成。采用30wt%含乙醇的水溶液作为粘合剂的1-5组的制粒收率结果如表2所示,同时,为考察制粒前后物料中粘合剂残留情况,分别检测透明质酸钠制粒前及制粒后的水分含量、乙醇残留量以及透明质酸钠含量,其中水分含量按照《中华人民共和国药典》二部附录ⅧL的方法测定,乙醇残留量及透明质酸钠含量按照行业标准《YY0308-2004医用透明质酸钠凝胶》检测方法检测,测定结果见表2。
表1
表2
从表2可以看出通过对比制粒前后透明质酸钠中的水分和乙醇残留,可见制粒前后透明质酸钠原料中的水分、乙醇残留及透明质酸钠含量并无显著差异,这表明未引入原料自身不含有的其他辅料。
(2)溶解性研究
将上述制粒研究中的2-4组中制备得到的透明质酸钠颗粒分别取1g室温下溶于100ml纯化水,500rpm进行搅拌,考察分散性和溶解时间,用1g同批次透明质酸钠粉末同等条件下进行对照,其结果如表3所示。
表3

从表3可以看出2-4组制备得到的透明质酸盐颗粒的分散性和溶解速度均显著提高,溶解速度相对于处理前的透明质酸钠粉末提高了10倍以上,三个组之间颗粒的分散性和溶解时间未有明显区别。
实施例2雾化压力和干燥温度的选择
(1)使用透明质酸钠的研究
将1kg分子量为1500k Da透明质酸钠粉末喷入FBM-3型沸腾制粒机(设备容量为3L),采用30%含乙醇的水溶液作为粘合剂,从沸腾制粒机的顶部喷入,透明质酸钠粉末与含乙醇的水溶液的质量比为1:1,处理84min后使用20目和60目的筛网进行筛选得到粒径介于20目和60目之间的透明质酸钠颗粒,考察不同雾化压力和进风温度以及物料温度下(参见表4)透明质酸钠的制粒效果,其结果如表5所示。
表4
表5
当雾化压力为0.02Mpa和0.3Mpa时,收率较低,制粒失败。
当雾化压力为0.04Mpa或0.2Mpa时,收率为50%以上。
(2)使用透明质酸锌的研究
将1kg分子量为1000k Da透明质酸锌粉末喷入FBM-3型沸腾制粒机(设备容量为3L),采用20%含乙醇的水溶液作为粘合剂,从沸腾制粒机的顶部喷入,透明质酸钠粉末与粘合剂的质量比为1:1,处理66min后使用20目和60目的筛网进行筛选得到粒径介于20目和60目之间的透明质酸锌颗粒,考察不同雾化压力和进风温度以及物料温度下(参见表6)透明质酸锌的制粒效果,其结果如表7所示,其中,当雾化压力为0.02Mpa时,收率最高仅有40%,透明质酸盐粉末与粘合剂未能均匀接触,制粒失败,雾化压力为0.3Mpa时,收率最高48%,透明质酸盐挂壁较多,制粒失败。
表6
表7
当雾化压力为0.02Mpa和0.3Mpa时,收率较低,制粒失败。
当雾化压力为0.04Mpa或0.2Mpa时,收率为50%以上。
实施例3透明质酸钠分子量和乙醇浓度的选择以及溶解性的研究
采用A组80k Da、B组200k Da、C组600k Da、D组2000k Da、E组2500k Da的透明质酸钠粉末,分别采用10wt%-60wt%含有乙醇的水溶液作为粘合剂,采用与实施例1相同的方法进行制粒,其中,雾化器压力为0.1Mpa,进风温度60℃,物料温度为43℃,处理84min后使用20目和60目的筛网进行筛选得到粒径介于20目和60目之间的透明质酸钠颗粒,其中,HA的分子量以及粘合剂的浓度如表8所示,并将所制备得到的颗粒按照实施例1中溶解性研究的方法进行操作,其制粒效果以及溶解性效果如表9所示,所述溶解性效果的溶解条件为室温下800rmp,1g固体颗粒加入100ml纯水中。
表8
表9

从表9可以看出,随着透明质酸钠分子质量增加,溶解时间延长,但溶解速度较未进行工艺处理的同批次透明质酸钠粉末均显著提升,其中,B~E组提升溶解速度均在5倍以上,A组由于透明质酸钠分子量较小,未制粒前的透明质酸钠的溶解速度相对大分子量的透明质酸钠更快,因此,制粒后溶解速度提高了3.8倍。
以上所述,仅是本申请的较佳实施例而已,并非是对本申请作其它形式的限制,任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本申请技术方案内容,依据本申请的技术实质对以上实施例所作的任何简单修改、等同变化与改型,仍属于本申请技术方案的保护范围。
