Stable Vitamin C and Ceramide Cosmetic Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developing stable cosmetic compositions that effectively deliver high amounts of ascorbic acid and ceramides to the skin has been challenging due to their instability and formulation difficulties.
Innovation Solution
The development of cosmetic compositions containing a combination of ascorbic acid, ceramides, panthenol, mono-alcohols, polyols, fatty compounds, emulsifiers, and cationic surfactants, which are formulated to provide a stable and effective delivery of these ingredients, resulting in a pleasant texture and absorption into the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high amounts of ascorbic acid and ceramides are formulated together, then the cosmetic composition provides effective skin treatment, but the stability of the composition deteriorates
Solution Approach 1:
The patent uses panthenol as an intermediary substance that mediates between ascorbic acid and ceramides. Panthenol forms a complex with these ingredients, acting as a stabilizing agent that prevents direct interaction between ascorbic acid and ceramides that would otherwise cause instability. This intermediary approach allows high concentrations of both active ingredients to coexist stably in the formulation.
Solution Approach 2:
The patent creates a composite cosmetic composition by combining ascorbic acid, ceramides, and panthenol in specific proportions. This composite formulation leverages the synergistic effects of multiple ingredients while maintaining stability through the carefully balanced composition. The composite structure allows the ingredients to work together effectively without compromising stability.
2Quantity of substance
If high concentrations of ascorbic acid are delivered to the skin, then the antioxidant and collagen production benefits are enhanced, but the formulation difficulty increases
Solution Approach 1:
Panthenol serves as a formulation intermediary that facilitates the incorporation of high concentrations of ascorbic acid into the cosmetic composition. It acts as a solubilizing agent and stabilizer, making the formulation process easier by preventing precipitation and degradation of ascorbic acid at high concentrations.
Solution Approach 2:
The patent optimizes the pH and composition parameters of the formulation to enhance ascorbic acid stability and deliverability. By carefully controlling the pH level and incorporating specific concentrations of panthenol and other ingredients, the formulation achieves high ascorbic acid concentration while maintaining ease of manufacture and product stability.
3Reliability
If ceramides are included in high amounts, then the skin barrier function is improved, but the formulation stability deteriorates
Solution Approach 1:
Panthenol acts as a mediating ingredient that enables high concentrations of ceramides to be incorporated into the formulation without compromising stability. It forms a compatible matrix that accommodates ceramides, preventing phase separation and maintaining uniform distribution throughout the product.

AI summary
The present disclosure relates to stable cosmetic compositions for delivering high amounts of ascorbic acid (vitamin C) and ceramides to the skin, products containing such cosmetic compositions, and methods for treating skin using the cosmetic compositions. The cosmetic compositions include ascorbic acid, one or more ceramides, panthenol, one or more monoalcohols having from 2 to 6 carbon atoms, one or more polyols, one or more fatty compounds, one or more emulsifiers, one or more cationic surfactants, and water. The cosmetic compositions are particularly useful for treating the effects of skin aging, for example, reducing the appearance of wrinkles and improving skin tone.
