Solid Cosmetic Formulation Using Syndets and Prebiotics for Skin Barrier Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid cosmetic formulations often disrupt the skin's microbial barrier and can be harsh on sensitive skin, while also consuming natural resources. Additionally, they may struggle with maintaining physical properties at lower pH levels, which can lead to stickiness and poor solidification.
Innovation Solution
A solid cosmetic formulation that includes a basic formulation comprising at least one syndet, two different prebiotics, and two different postbiotics, such as lactic acid and arginine, without a molding stage. This formulation maintains a pH between 5 and 6, ensuring compatibility with the skin's natural pH and minimizing water content to less than 5% for improved conservation and skin compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional soaps are used for cleansing, then cleaning properties are achieved, but the skin's microbial barrier is disrupted and natural resources are consumed
Solution Approach 1:
The patent changes the chemical composition parameters by using syndets (synthetic detergent-like entities) instead of conventional soaps, and by carefully controlling pH levels (5-6) to match skin's natural pH. This parameter change allows the formulation to maintain cleaning efficacy while preserving the skin's microbial barrier, as syndets are less disruptive to skin flora than traditional soaps.
Solution Approach 2:
The invention creates a composite formulation combining multiple components: syndets for cleaning, prebiotics to support beneficial skin bacteria, and postbiotics to soothe and protect skin. This composite approach addresses both cleaning needs and microbial barrier protection simultaneously, resolving the contradiction between effective cleansing and preserving skin flora.
2Object-affected harmful factors
If pH is lowered below 6 for better skin compatibility, then skin compatibility improves, but physical properties deteriorate causing stickiness and poor solidification
Solution Approach 1:
The patent optimizes the pH parameter to a specific range (5-6) that balances skin compatibility with physical stability. This precise parameter control prevents the stickiness and poor solidification that occur at lower pH levels, while still maintaining compatibility with skin's natural pH. The formulation achieves this through careful selection of syndet components and buffering agents.
Solution Approach 2:
The invention applies different functional components to different aspects of the formulation: syndets provide cleaning and contribute to solid structure, prebiotics support microbial balance, and postbiotics provide soothing effects. This localized functional assignment allows the formulation to achieve low pH for skin compatibility without compromising overall physical stability, as each component compensates for potential weaknesses.
3Ease of manufacture
If solid cosmetic formulations are made with traditional ingredients, then manufacturing is simple, but they are harsh on sensitive skin and consume natural resources
Solution Approach 1:
The patent changes the ingredient parameters by replacing traditional harsh surfactants with milder syndets and incorporating prebiotics and postbiotics. These parameter changes maintain manufacturing simplicity while significantly reducing harshness on sensitive skin. The formulation process remains straightforward, involving mixing and solidification, but the chemical composition parameters are optimized for gentleness.
Solution Approach 2:
The invention creates a composite formulation that combines syndets, prebiotics, and postbiotics in specific proportions. This composite approach maintains ease of manufacture through a single-step mixing process while achieving gentle action on sensitive skin. The synergistic interaction between components provides both cleaning efficacy and skin protection without requiring complex manufacturing procedures.
4Ease of manufacture
If water content is increased for better processing, then formulation processing improves, but conservation and skin compatibility worsen
Solution Approach 1:
The patent optimizes the water content parameter to a low level that maintains both processing ease and conservation benefits. The formulation achieves this by using syndets and other components that provide sufficient workability at low water content, eliminating the need for high water levels that would compromise conservation and skin compatibility. This parameter optimization allows the formulation to remain processable while maintaining its low-water advantages.
