Natural Glidant Composition for Tablet Flowability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current natural glidant systems for oral solid dosage forms face challenges in maintaining reliable tablet hardness, friability, and dissolution profiles, often resulting in adverse processing characteristics like reduced flowability and compressibility, and batch variations, with no commercially available systems comprised entirely of natural, certified organic components.
Innovation Solution
A glidant pre-mix composition comprising pea starch powder, bamboo extract powder, and bamboo fiber, in specific weight percentages, enhances the flowability and compressibility of powder blends, allowing direct compression of tablets without pre-processing, and is free from artificial glidants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If natural glidant systems are used in oral solid dosage forms, then health and safety concerns are addressed and consumer acceptance is improved, but reliable tablet hardness, friability, and dissolution profiles cannot be maintained
Solution Approach 1:
The patent applies composite materials by combining multiple natural components (pea starch, bamboo extract, bamboo fiber) to create a glidant system that achieves both health safety and reliable tablet properties. This composite approach allows the formulation to benefit from the complementary properties of each component while maintaining natural status.
Solution Approach 2:
The patent employs parameter changes by optimizing the weight ratios of components (pea starch: 10-50%, bamboo extract: 40-90%, bamboo fiber: 0-30%) to achieve the desired balance between flowability enhancement and maintenance of tablet quality attributes. This systematic variation of composition parameters enables the resolution of the contradiction.
2Object-generated harmful factors
If natural glidant systems are used, then artificial additives are eliminated, but adverse processing characteristics occur such as reduced flowability and compressibility
Solution Approach 1:
The patent applies universality by designing a multi-functional natural glidant system where the composite formulation simultaneously provides flowability enhancement, compressibility improvement, and maintains natural status. The combination of components creates synergistic effects that achieve multiple desirable properties without artificial additives.
3Object-generated harmful factors
If natural glidant systems are used, then clean label products are achieved, but batch variations occur
Solution Approach 1:
The patent applies parameter changes by establishing specific weight ratio ranges for each component (pea starch: 10-50%, bamboo extract: 40-90%, bamboo fiber: 0-30%) to minimize batch variations. This systematic parameter optimization ensures consistent performance across batches while maintaining the clean label attribute.
Applied Scientific Principles

Function Achieved in This Case
The all-natural glidant composition improves process performance in tableting and capsule filling, ensuring critical quality attributes and enabling a clean label, with enhanced flowability and compressibility comparable to synthetic glidants like colloidal silicon dioxide.
Implementation Method 1
Glidants are excipients that reduce inter-particulate friction, resulting in improved flow of granules and powders

AI summary
The present invention relates to a premix of different natural/organic glidants to ensure efficient tablet manufacturing and batch to batch consistency with avoiding the risk of having sticking problems during the manufacturing process. The tablets may be labelled as "natural". The inventive premix may replace conventional glidants like colloidal silicon dioxide or talc.
