Lip Cosmetic Composition for Stable Velvety Matte Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lip care and makeup products struggle to achieve a smooth, comfortable, matte, and non-drying application with a velvety feel, often compromising stability due to the incompatibility of silicone compounds with non-silicone components and volatile oils.
Innovation Solution
A solid cosmetic composition comprising organopolysiloxane elastomers at least 7% by weight, combined with non-polar oils and polar waxes, ensuring compatibility and stability while maintaining a matte finish and hydration, using an anhydrous formulation with specific hardness properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If volatile oils and fillers are used to achieve a matte finish, then the matte effect is improved, but the stability of the formula is compromised and a drying effect on the lips occurs
Solution Approach 1:
The patent changes the chemical parameters of the formula by using organopolysiloxane elastomers with specific molecular weights and viscosities (≥7% by weight) instead of traditional volatile oils and fillers. This parameter change achieves the matte finish while maintaining formula stability and preventing drying effects on the lips.
Solution Approach 2:
The patent employs a composite material system combining organopolysiloxane elastomers with specific oils and waxes. This composite approach creates a stable formulation that delivers matte finish without the drawbacks of volatile oils, as the elastomer network provides structural integrity while the oil phase ensures compatibility and comfort.
2Ease of operation
If silicone compounds are used in significant quantities, then the velvety feel and comfort are improved, but incompatibility with non-silicone compounds occurs
Solution Approach 1:
The patent specifies precise parameter ranges for the silicone elastomer including molecular weight (≥10,000), viscosity (50-5000 cSt), and concentration (≥7% by weight). These parameter optimizations ensure the elastomer provides velvety feel while remaining compatible with the non-silicone oil and wax components in the formulation.
Solution Approach 2:
The patent creates local quality differentiation by having the silicone elastomer form a distinct network structure within the oil phase. The elastomer particles are dispersed throughout the formulation, providing localized velvety texture and comfort while the continuous oil phase maintains overall compatibility and stability of the composition.
3Shape
If non-polar oil and polar wax are combined, then the desired properties of matte finish and comfort are achieved, but incompatibility between the two components occurs
Solution Approach 1:
The patent optimizes the parameters of both non-polar oil and polar wax components, specifying their proportions and physical properties. The non-polar oil provides the matte finish while the polar wax content (≥5% by weight) ensures compatibility with the silicone elastomer. The balanced formulation achieves both matte appearance and component stability.
Solution Approach 2:
The organopolysiloxane elastomer acts as an intermediary between the non-polar oil and polar wax components. The elastomer network bridges these incompatible phases, allowing the non-polar oil to provide matte finish while the polar wax maintains compatibility, resulting in a stable homogeneous formulation with desired aesthetic and sensory properties.
