Solution Overview
Problem
Existing solid cosmetic compositions, particularly lip makeup, often suffer from tackiness, dryness, and lack of hydration, while also being difficult to apply and having poor stability and migration issues.
Innovation Solution
A solid cosmetic composition comprising a continuous fatty phase with silicone polyamide, silicone resin, non-volatile polar hydrocarbon-based oil, and polar wax, along with an aqueous phase, which provides a balanced texture for easy application, hydration, and stability, with a specific ratio of ingredients to ensure non-tackiness and effective dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If silicone polymers of the polysiloxane/polyamide type are associated with silicon resins to increase stability, then stability is improved, but the composition becomes more difficult to apply, tacky, and causes dryness
Solution Approach 1:
The patent applies parameter changes by precisely controlling the silicone polyamide content (0.1-10% by weight) and wax content (5-30% by weight) to optimize the balance between stability and ease of application. This quantitative parameter adjustment resolves the contradiction by finding the optimal concentration range where both stability and applicability are satisfied.
Solution Approach 2:
The patent uses composite materials by combining silicone polyamide, silicon resin, polar hydrocarbon-based oil, and polar wax in specific proportions. This multi-component composite system achieves enhanced stability while maintaining ease of application through the synergistic interaction of different materials with complementary properties.
2Ease of operation
If an aqueous phase is incorporated to improve comfort and hydration, then comfort is improved, but no additional benefit is generally obtained and stability may be compromised
Solution Approach 1:
The patent uses polar hydrocarbon-based oil and polar wax as intermediary substances that bridge the aqueous phase and the fatty continuous phase. These intermediaries enable the aqueous phase to be incorporated for comfort and hydration benefits while maintaining overall composition stability through compatible interaction with other components.
3Object-generated harmful factors
If the composition is made non-tacky by adjusting ingredients, then non-tackiness is improved, but application smoothness and stretchability may be compromised
Solution Approach 1:
The patent applies parameter changes by adjusting the silicone polyamide content (0.1-10% by weight) and wax content (5-30% by weight) to simultaneously achieve non-tackiness and application smoothness. This precise parameter optimization resolves the contradiction by finding the concentration range where both anti-tackiness and smooth application are satisfied.
