Anhydrous Solid Surfactant Composition for Shampoo Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair care products are packaged in non-biodegradable plastics, leading to environmental concerns and inefficiencies in carbon footprint, and solid compositions like bars are difficult to apply uniformly.
Innovation Solution
A process involving mixing an anhydrous solid composition of anionic and amphoteric or zwitterionic surfactants with water, followed by agitation and standing, to create a ready-to-use aqueous shampoo that can be packaged in biodegradable materials and reduces carbon footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional aqueous shampoo is packaged in plastic bottles, then good stability and storage are achieved, but environmental pollution and carbon footprint increase
Solution Approach 1:
The patent changes the physical state of the shampoo from liquid to solid by removing water, transforming it into an anhydrous composition. This solid form can be packaged in biodegradable materials like paper or plant-based containers instead of plastic bottles, eliminating environmental pollution while maintaining stability during storage and transport.
Solution Approach 2:
The invention utilizes phase transition by dehydrating the shampoo formulation, converting it from a liquid aqueous solution to a solid anhydrous composition. This phase change enables the product to be stored and transported in eco-friendly biodegradable packaging without compromising its functional stability.
2Object-affected harmful factors
If solid composition in cake or bar form is used, then plastic packaging is reduced, but uniform application to hair becomes difficult
Solution Approach 1:
The solid anhydrous shampoo is formulated as fine particles or powder rather than a monolithic bar or cake. This segmentation allows the composition to be easily dispersed and distributed uniformly throughout the hair during application, solving the problem of non-uniform application while maintaining plastic-free packaging.
Solution Approach 2:
By changing the physical form from solid bar to fine particulate material, the invention enables easy and uniform distribution over the hair surface. The particulate form can be readily picked up and applied, and the fine particle size ensures even coverage without the handling difficulties associated with solid bars.
3Ease of operation
If anhydrous solid composition is prepared by mixing with water and standing for at least 20 minutes, then ready-to-use shampoo with good performance is obtained, but preparation time increases
Solution Approach 1:
The anhydrous solid composition is pre-formulated with all necessary surfactants and ingredients in the correct proportions during manufacturing. This preliminary preparation ensures that when the consumer adds water at home, the composition reconstitutes quickly and uniformly, achieving ready-to-use shampoo quality within 20 minutes without requiring complex mixing or preparation steps.
