Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional moisturizing formulations fail to provide sustained hydration, are unstable, and can cause skin irritation due to inadequate penetration, separation of active ingredients, microbial contamination, and the use of harsh preservatives, limiting their suitability for all skin types.
Innovation Solution
A novel moisturizing formulation using DI Water, Aloe Barbadensis Leaf, Vitamin C, Glycerin, and Hyaluronic Acid in varying molecular weights, combined with Nipaguard SCE preservative, ensuring deep penetration, stability, and safety through meticulous mixing protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If traditional moisturizing formulations are used, then initial hydration is provided, but sustained hydration and deep penetration are insufficient
Solution Approach 1:
The formulation segments hyaluronic acid into multiple molecular weights (high, medium, low) to address different skin depths. High molecular weight HA provides surface hydration and film formation, while low molecular weight HA penetrates deeper into the skin matrix, ensuring both sustained hydration and reliable deep penetration without requiring a single complex delivery system.
Solution Approach 2:
The patent changes the molecular weight parameter of hyaluronic acid from a single value to a distribution across multiple weights. This parameter change enables the formulation to achieve both long-duration surface hydration (through high MW HA film) and deep penetration (through low MW HA diffusion), resolving the contradiction between duration and penetration depth.
2Reliability
If conventional preservatives are used, then microbial contamination is prevented, but skin irritation and allergic reactions occur
Solution Approach 1:
The patent changes the chemical nature parameter of the preservative from conventional synthetic agents (parabens, phenoxyethanol) to a naturally-derived alternative (Nipaguard SCE based on ferulic acid and sorbic acid). This parameter change maintains reliable microbial protection through the preservative mechanism while eliminating the harmful irritation and allergic reactions associated with conventional preservatives.
3Stability of the object's composition
If formulation stability is improved through conventional methods, then separation and degradation are reduced, but active ingredient efficacy decreases due to harsh conditions
Solution Approach 1:
The patent introduces pH adjusters (citric acid, sodium hydroxide) and chelating agents (EDTA) as intermediary substances that mediate between the need for formulation stability and the preservation of active ingredient efficacy. These intermediaries control the chemical environment to prevent degradation and separation while maintaining conditions suitable for vitamin C and other sensitive actives, resolving the contradiction between stability and efficacy.
4Reliability
If synthetic ingredients are used to treat skin conditions, then treatment effectiveness is achieved, but suitability for all skin types is reduced
Solution Approach 1:
The patent employs naturally-derived ingredients (aloe vera, vitamin C, ferulic acid, sorbic acid) that perform multiple functions: aloe vera provides both soothing and hydration, vitamin C offers antioxidant protection and brightening, ferulic acid delivers both preservative action and antioxidant benefits. This multi-functionality achieves reliable treatment effectiveness while ensuring versatility and suitability for all skin types including sensitive skin.

AI summary
The present invention relates to a novel formulation of a moisturizing formulation and a method for its production. The formulation is designed to provide enhanced hydration, improved skin elasticity, and long-term stability, making it suitable for all skin types, including sensitive skin. The formulation includes a unique combination of ingredients that synergistically contribute to the formulation's effectiveness. Key components include DI Water, Aloe Barbadensis Leaf, Glycerin, Hyaluronic Acid in both high and low molecular weights, Vitamin C, and a naturally derived preservative, Nipaguard SCE. Additionally, the formulation incorporates Astragalus Membranaceus Root Extract, known for its anti-aging and immune-boosting properties, which enhances the skin's resilience against environmental stressors. The method of production involves a process of mixing ingredients in a specific sequence to ensure stability and prevent premature reactions, with particular attention to the homogeneous distribution of components like Xanthan Gum and the proper dispersion of Hyaluronic Acid. This careful preparation method ensures that the final product not only meets the hydration needs of the skin but also remains effective and stable over time. The invention offers a significant advancement in skincare technology, providing a reliable and safe product that delivers both immediate relief and long-term benefits to skin hydration and health.
