Unmodified Clay Cosmetic Composition Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in developing natural cosmetic products that are stable, have low environmental impact, and offer sensory performance qualities equivalent to conventional products, particularly in terms of freshness, deodorancy, and texture, while avoiding the use of synthetic ingredients like high-performance nonsoaping emulsifiers and silicones.
Innovation Solution
A composition comprising unmodified trioctahedral smectites, magnesium salts, antisyneresis agents such as propylene glycol, and water, which prevents syneresis and provides a stable, non-tacky, and deodorant performance with a pH that does not require preservatives, enhancing the cosmetic and sensory qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If natural clays such as hectorites are used to texturize water, then the cosmetic performance and sensory qualities are improved, but the stability over time deteriorates due to syneresis
Solution Approach 1:
Magnesium salts are introduced as an intermediary substance that mediates between the natural clay and water components. The magnesium ions interact with the clay structure to prevent syneresis while preserving the texturizing and sensory benefits, effectively acting as a stabilizing mediator in the formulation.
Solution Approach 2:
The invention changes the chemical composition parameters of the system by adding magnesium salts, which alter the ionic environment and prevent the syneresis phenomenon. This parameter change (adding Mg2+ ions) stabilizes the clay-water system without compromising its sensory performance.
2Stability of the object's composition
If conventional synthetic ingredients are used to achieve stable and high-performance cosmetic products, then the stability and performance are improved, but the environmental impact worsens
Solution Approach 1:
The invention extracts and eliminates harmful synthetic ingredients (nonsoaping emulsifiers, crosslinked polymers, silicones) from the formulation while retaining the essential functional components. By taking out these problematic substances and replacing them with natural alternatives enhanced by magnesium salts, the product achieves both stability and environmental compatibility.
Solution Approach 2:
The formulation changes the compositional parameters by substituting synthetic chemicals with natural ingredients and magnesium-based compounds. This parameter change in chemical composition maintains product stability while reducing environmental harm, aligning with green chemistry principles.
3Reliability
If magnesium salts are used in cosmetic compositions, then the deodorant effect and mattness are improved, but the formulation complexity increases when combining with unmodified clays
Solution Approach 1:
The invention merges multiple functional components (unmodified clay for texturizing, magnesium salts for deodorancy and mattness, and antisyneresis agents) into a single integrated formulation. This combination approach consolidates multiple benefits into one product system, managing complexity through synergistic ingredient selection rather than separate products.
Solution Approach 2:
The magnesium salt component serves multiple functions simultaneously: it prevents syneresis of the clay, provides deodorant effect, contributes to mattness, and enhances overall formulation stability. This multi-functionality reduces the need for additional separate ingredients, thereby managing formulation complexity while achieving diverse performance goals.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition is stable, pleasant on application, non-tacky, and offers high-level deodorant and matting performance, maintaining these qualities even under extreme conditions, such as in a steam room, while being environmentally friendly.
Implementation Method 1
natural clays, such as natural hectorites, which can texturize water by virtue of their specific structure comprising interfoliar cations which can be hydrated, in order to form aqueous gels
Implementation Method 2
an antisyneresis agent chosen from polyols, natural polymers, organic or nonorganic fillers, crystallizable fatty substances and their mixtures, and water, and to the use of said composition in the field, in particular cosmetic field
