Natural Vegetable Oil and Lime Water Composition Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compositions based on olive oil and lime water for skin care, such as 'limestone liniment', face stability issues over time, requiring non-natural stabilizers or excessive beeswax, which affects fluidity and gentleness.
Innovation Solution
A natural composition combining 40-54% vegetable oil, 40-60% calcium hydroxide solution, 0.5-8% beeswax, and 0.1-1.2% natural vegetable wax derivatives like jojoba ester or sunflower wax, providing long-term stability without phase separation and maintaining fluidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If beeswax is added to olive oil and lime water composition, then emulsification and short-term stability are improved, but long-term stability is not achieved without significantly thickening the composition
Solution Approach 1:
The patent combines beeswax with vegetable wax derivatives (such as jojoba ester, sunflower wax, or mimosa wax) to create a composite wax system. This composite approach allows the composition to achieve both short-term and long-term stability while maintaining fluidity, as the different wax components work synergistically to provide stabilization without excessive thickening.
Solution Approach 2:
The patent optimizes the concentration parameters of beeswax (0.5-8% by weight) and vegetable wax derivatives (0.1-1.2% by weight) to achieve the desired balance between stability and fluidity. By carefully controlling these parameter ranges, the composition maintains its fluid characteristics while obtaining durable stabilization without phase separation.
2Stability of the object's composition
If larger quantity of beeswax is added to achieve long-term stability, then stability is improved, but composition becomes too thick and application becomes difficult
Solution Approach 1:
The patent uses a composite wax system combining beeswax with vegetable wax derivatives in specific proportions. This composite approach provides long-term stability equivalent to or better than using large amounts of beeswax alone, while the vegetable wax components contribute to maintaining a softer, more gentle texture suitable for skin application.
Solution Approach 2:
The patent establishes specific concentration ranges for beeswax (0.5-8% by weight) and vegetable wax derivatives (0.1-1.2% by weight) to achieve long-term stability without excessive thickening. This parameter optimization ensures the composition remains easy to apply while providing durable stabilization.
3Stability of the object's composition
If non-natural stabilizers are added to achieve stability, then stability is improved, but natural composition requirement is not met
Solution Approach 1:
The patent replaces synthetic stabilizers with natural vegetable wax derivatives (jojoba ester, sunflower wax, mimosa wax) that provide effective stabilization. These natural alternatives achieve the desired stability without compromising the natural origin of the composition, eliminating the need for petrochemical-based stabilizers.
Solution Approach 2:
The patent optimizes the concentration of vegetable wax derivatives (0.1-1.2% by weight) to achieve effective stabilization naturally. This parameter control ensures that the natural ingredients provide sufficient stability without requiring synthetic additives.
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 achieves long-term stability and fluidity, suitable for topical application, without the need for non-natural stabilizers, ensuring effective skin protection and comfort.
Implementation Method 1
add beeswax, on the one hand to facilitate emulsification between the aqueous phase and the oily phase
Implementation Method 2
a thin lipid film coats the skin. This helps to protect the skin from the acidity of urine
