Granular Cosmetic Composition for Controlled Foaming and Low-Water Rinsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keratin fiber cleaning products, such as shampoos and dry shampoos, face challenges with dosing, stability, foaming control, and effectiveness in eliminating sebum and providing lasting cleanliness, while dry powder compositions are difficult to handle and require excessive rinsing water.
Innovation Solution
A cosmetic composition comprising at least 50% by volume of disintegrating granules containing anionic surfactants, absorbent agents, and thickening agents, which form a stable foam upon contact with water, allowing controlled foaming and reduced rinsing water usage, with a slow disintegration speed for enhanced cleansing and cosmetic benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If dry powder compositions are used, then ease of handling during manufacture is improved, but dust presence during use increases and rinsing water requirement increases
Solution Approach 1:
The composition is segmented into granular form rather than fine powder, maintaining ease of handling during manufacture while reducing dust generation during use. The granules are formed by agglomerating smaller particles, creating a structure that is easier to handle but less prone to becoming airborne dust.
Solution Approach 2:
The physical state parameter is changed from fine powder to granular form, which fundamentally alters both the handling characteristics during manufacture and the dust generation behavior during use. This parameter change resolves the contradiction by improving one aspect while mitigating the negative effect of the other.
2Ease of manufacture
If dry powder compositions are used, then ease of handling during manufacture is improved, but rinsing water requirement increases
Solution Approach 1:
The granular structure segments the surfactant delivery system, allowing for more controlled dissolution and foaming. This segmentation enables the composition to generate sufficient foam with less water, reducing the rinsing water requirement while maintaining ease of handling during manufacture.
Solution Approach 2:
Changing the physical form from powder to granules modifies the water interaction characteristics, enabling efficient foaming with reduced water quantities. This parameter change addresses both the handling ease during manufacture and the reduced rinsing water requirement.
3Object-generated harmful factors
If conventional liquid shampoos are used, then foaming ability is improved, but dosing difficulty increases and packaging leakage increases
Solution Approach 1:
The granular composition acts as an intermediary form between liquid shampoo and dry powder. It maintains the foaming ability of liquid shampoos while providing the dosing control and packaging stability of dry forms. The granules dissolve and foam upon contact with water, bridging the advantages of both liquid and dry formulations.
Solution Approach 2:
The physical state is changed from liquid to granular solid, which fundamentally alters the dosing behavior and packaging characteristics while preserving foaming ability. This parameter transformation resolves the contradiction by maintaining the beneficial foaming property while eliminating the dosing and leakage problems.
4Ease of operation
If dry shampoos are used, then dosing ease is improved, but sebum elimination effectiveness deteriorates and feeling of cleanliness persistence deteriorates
Solution Approach 1:
The granular composition serves as an intermediary that combines the dosing ease of dry shampoos with the sebum elimination effectiveness of liquid shampoos. The granules contain surfactants that actively cleanse sebum while maintaining easy dosing control, bridging the gap between the two formulations.
Solution Approach 2:
The composition is a composite material combining granular structure with surfactant components, creating a product that exhibits both the handling advantages of dry forms and the cleansing effectiveness of liquid forms. This composite approach resolves the contradiction between dosing ease and sebum elimination effectiveness.
5Object-generated harmful factors
If aerosol shampoos with powders are used, then foaming ability is improved, but stability deteriorates
Solution Approach 1:
The aerosol delivery system is extracted and replaced with a simple granular formulation. By removing the aerosol propellant and pressurized container system, the foaming ability is maintained through the granular surfactant composition while the stability problem of aerosol systems is eliminated. The granules provide inherent stability without requiring pressurized containment.
