Transparent Personal Cleansing Composition Foam and Mildness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shower oils face challenges with low foaming performance and the use of harsh, non-sustainable ingredients such as MIPA laureth sulfate, fatty alcohol ethoxylates, and petrochemicals, which irritate skin and harm the environment, while 'sulphate-free' alternatives suffer from poor foam and aquatic toxicity.
Innovation Solution
A waterless, transparent personal cleansing composition with a minimum 80% natural origin content, using a combination of vegetable oils, lauryl alcohol, glyceryl mono laurate or glyceryl lauryl ether, and triisopropanol amine lauroyl sarcosinate, which significantly improves foam generation and replaces toxic surfactants, maintaining mild cleansing and sustainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If MIPA laureth sulfate and fatty alcohol ethoxylates are used as surfactants in shower oils, then foaming performance is improved, but skin irritation and environmental harm increase
Solution Approach 1:
The patent changes the chemical parameters of the surfactant system by replacing MIPA laureth sulfate and fatty alcohol ethoxylates with TIPA lauroyl sarcosinate and glyceryl mono laurate. This parameter change maintains the necessary foaming performance while eliminating the harmful skin irritation and environmental damage associated with the previous surfactant composition.
Solution Approach 2:
The patent converts the harmful effects of traditional surfactants into benefits by using TIPA lauroyl sarcosinate, which provides gentle cleansing action. The sarcosinate structure allows for effective foam formation while the TIPA base provides mildness, transforming the harmful harshness of traditional surfactants into beneficial gentle cleansing.
2Object-affected harmful factors
If sulphate-free alternatives like TIPA lauroyl sarcosinate are used, then skin irritation is reduced, but foaming performance deteriorates
Solution Approach 1:
The patent uses a composite surfactant system combining TIPA lauroyl sarcosinate (anionic) with glyceryl mono laurate (non-ionic). This composite approach leverages the mildness of the sarcosinate while the glyceryl mono laurate contributes to foam stability and volume, achieving both low irritation and good foaming performance simultaneously.
Solution Approach 2:
The patent introduces glyceryl mono laurate as an intermediary non-ionic surfactant that mediates between the anionic TIPA lauroyl sarcosinate and water. This intermediary component enhances foam formation and stability while maintaining the mildness of the sarcosinate, effectively bridging the gap between sustainability and foaming performance.
3Productivity
If fatty alcohol ethoxylates are used to boost foam, then foaming performance is improved, but aquatic toxicity increases
Solution Approach 1:
The patent replaces persistent fatty alcohol ethoxylates with biodegradable TIPA lauroyl sarcosinate and glyceryl mono laurate. These new surfactants are designed to break down more quickly in the environment, reducing aquatic toxicity while maintaining effective foaming performance for the duration of use.
Solution Approach 2:
The patent changes the molecular structure parameters of the surfactants from ethoxylated fatty alcohols to sarcosinate-based compounds with different hydrophilic-lipophilic balances. This parameter change enables effective foam generation while improving biodegradability and reducing environmental persistence, thereby lowering aquatic toxicity.
4Object-generated harmful factors
If waterless vegetable oil-based composition is used, then sustainability is improved, but foaming performance may be compromised
Solution Approach 1:
The patent employs self-assembling surfactant structures where TIPA lauroyl sarcosinate and glyceryl mono laurate automatically organize into micelles and foam structures when contacted by water. This self-service mechanism eliminates the need for additional foam boosters or complex formulation processes, achieving effective foaming in a simple waterless oil-based system.
Solution Approach 2:
The patent creates a composite emulsion system combining vegetable oils with TIPA lauroyl sarcosinate and glyceryl mono laurate. This composite formulation leverages the natural properties of vegetable oils as carriers while the surfactants provide foam generation, achieving both environmental sustainability and effective foaming performance in a unified system.
