Moisturizer Composition Without Emulsifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current moisturizers often require trial and error to find the right composition for individual skin types and conditions, as their effectiveness can vary based on factors like skin type, age, and specific conditions, and they may contain unnecessary additives like emulsifiers, surfactants, and rheology modifiers.
Innovation Solution
A moisturizer composition comprising niacinamide, pantothenic acid, pyridoxine, a skin barrier enhancer, humectant, citric acid, ascorbic acid, and natural preservatives in a water-glycerin mixture, optimized for specific weight ratios and ingredient concentrations, without emulsifiers, surfactants, and rheology modifiers, providing a balanced and effective skin hydration solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If moisturizers contain multiple additives (emulsifiers, surfactants, rheology modifiers) to achieve desired texture and stability, then product performance and stability are improved, but product complexity and potential skin irritation increase
Solution Approach 1:
The patent removes unnecessary additives (emulsifiers, surfactants, rheology modifiers) from the moisturizer formulation, retaining only essential ingredients like water, glycerin, niacinamide, and natural preservatives. This extraction of non-essential components simplifies the product while maintaining core moisturizing functionality and stability.
Solution Approach 2:
The patent applies specific concentration ranges to key ingredients (e.g., niacinamide at 1-5 wt%, glycerin at 10-30 wt%) to achieve optimal performance. By carefully controlling the quality and amount of each component rather than using multiple additives, the formulation achieves stability with simpler composition.
2Adaptability or versatility
If moisturizers are formulated with specific ingredient concentrations to target individual skin types and conditions, then effectiveness for specific skin conditions is improved, but formulation complexity increases
Solution Approach 1:
The patent creates a universal moisturizer formulation that can address multiple skin conditions (dry skin, sensitive skin, acne-prone skin) through a single base composition. The core ingredients like niacinamide, glycerin, and natural preservatives provide broad-spectrum benefits, reducing the need for multiple specialized products while maintaining adaptability to different skin types through adjustable concentration ranges.
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 moisturizer composition effectively hydrates and protects the skin, offering a tailored solution for various skin types and conditions without the need for additional additives, ensuring stability and microbial resistance.
Implementation Method 1
niacinamide (Vitamin B3)...hydrate and strengthen the skin barrier
Implementation Method 2
pantothenic acid (Vitamin B5)...soothe and hydrate the skin
Implementation Method 3
pyridoxine (Vitamin B6)...regulate oil production and reduce inflammation
Implementation Method 4
Humectants usually contain ingredients such as ingredients such as hyaluronic acid, glycerin, lactic acid, alpha hydroxy acids (AHA), or urea. They hydrate the skin by drawing moisture from the air to the outer layers of the skin, the epidermis, and stratum corneum, replenishing the skin.
Implementation Method 5
about 0.05 to about 1 wt % of a skin barrier enhancer
Implementation Method 6
about 0.1 to about 0.5 wt % of an ascorbic acid salt or an ascorbic acid derivative
Implementation Method 7
about 1 to about 10 wt % citric acid
Implementation Method 8
about 0.5 to about 2 wt % of a natural preservative
