Semi-Solid Perfume Composition Without Ethanol or Silicone
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid and semi-solid perfumes contain synthetic ingredients, are not natural, and often have drawbacks such as stickiness, greasiness, and instability, making them unsuitable for COSMOS certification and consumer preferences for natural, ethanol-free, and silicone-free products.
Innovation Solution
A perfumed composition comprising 5-40% perfume, 10-15% trihydroxystearin, and 40-85% triethyl citrate, which is free of silicone and ethanol, providing a stable, non-sticky, and non-greasy texture suitable for COSMOS certification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If solid or semi-solid perfumes are formulated with traditional ingredients (silicones, aqueous gelling agents, ethanol), then the composition can maintain a gel or solid form, but the product becomes sticky, greasy, drying, or contains synthetic ingredients that prevent COSMOS certification
Solution Approach 1:
The patent changes the chemical parameters of the formulation by replacing traditional gelling agents (silicones, aqueous agents) with a specific natural wax ester combination. This parameter change transforms the physical properties of the composition, eliminating stickiness and greasiness while maintaining solid/semi-solid form, thereby resolving the contradiction between ease of operation and harmful factors.
Solution Approach 2:
The patent extracts and removes harmful synthetic ingredients (silicones, ethanol, aqueous gelling agents) from the formulation. By taking out these problematic components and replacing them with COSMOS-certifiable natural ingredients, the invention eliminates the harmful effects of stickiness, greasiness, and drying while preserving the desired sensory experience.
2Reliability
If natural ingredients are used to achieve COSMOS certification, then the product becomes free of synthetic ingredients, but formulating a stable, highly perfumed solid or semi-solid composition becomes difficult
Solution Approach 1:
The patent uses a composite material approach by combining specific natural ingredients (wax esters, plant oils, natural perfume) in precise proportions. This composite formulation achieves both COSMOS certification compliance and composition stability, resolving the contradiction between reliability and stability. The specific combination of ingredients creates a synergistic effect that maintains stability while meeting natural certification requirements.
3Productivity
If ethanol is used as a solvent in perfume formulations, then the perfume can be effectively delivered, but the product becomes drying to the skin and contains synthetic ingredients
Solution Approach 1:
The patent extracts and removes ethanol from the formulation, replacing it with natural plant oils and wax esters. This elimination of the harmful solvent maintains effective perfume delivery through the natural lipid-based system while removing the drying effect associated with ethanol, thereby resolving the contradiction between productivity and harmful factors.
4Ease of operation
If silicone elastomer is used to create a silky gel texture, then the sensory experience is improved, but the product contains synthetic ingredients that prevent COSMOS certification
Solution Approach 1:
The patent removes silicone elastomer from the formulation and replaces it with a natural wax ester-based system. This extraction of the synthetic ingredient eliminates the barrier to COSMOS certification while the natural lipid combination replicates the desired silky gel texture, resolving the contradiction between ease of operation and reliability.
