Flexible Solid Makeup Product Using Carrageenin Gel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Compact cosmetic products, such as eyeshadows, lack flexibility and resistance to deformation and impact, leading to breakage and poor usability, especially for products with dry skin and during transportation.
Innovation Solution
A cosmetic product in a flexible solid form is created using a mixture of cosmetic powders and carrageenins, which provides a unique texture combining the advantages of compact products with enhanced elasticity and impact resistance, allowing for a compact appearance with a consistency similar to extruded products when applied, and being inert until wetted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If compact cosmetic products are made solid for easy transport and storage, then space occupation is reduced and portability is improved, but flexibility and resistance to deformation and impact deteriorate, leading to breakage
Solution Approach 1:
The patent changes the physical and chemical parameters of the cosmetic product by incorporating specific polymers (carboxymethyl cellulose, hydroxyethyl cellulose, polyvinyl alcohol) and plasticizers (glycerol, propylene glycol) in optimized concentrations. This transforms the product from a brittle solid to a flexible solid with enhanced mechanical properties, achieving both compactness and resistance to deformation.
Solution Approach 2:
The patent creates a composite material system combining cosmetic powders (talc, mica, pigments) with polymer matrices and plasticizers. This composite structure provides both the desired cosmetic functionality and improved mechanical strength, allowing the product to maintain solid form for portability while resisting breakage through the flexible polymer network.
2Volume of moving object
If compact cosmetic products are made solid to reduce space occupation, then portability is improved, but the product tends to break easily when subjected to impacts
Solution Approach 1:
The patent modifies the mechanical parameters of the cosmetic product by adjusting the polymer concentration (0.5-5% carboxymethyl cellulose, 0.1-2% hydroxyethyl cellulose, 0.1-1% polyvinyl alcohol) and plasticizer content (5-20% glycerol, 1-10% propylene glycol). These parameter changes increase the product's toughness and impact resistance while maintaining its compact solid form.
Solution Approach 2:
The patent creates a flexible solid structure that can deform under impact without breaking. The polymer-plasticizer matrix acts as a flexible network that absorbs impact energy through deformation, preventing the product from shattering while maintaining its compact form factor.
3Ease of operation
If compact cosmetic products are made solid for easier packing and transport, then ease of operation is improved, but the texture is not comfortable for subjects with dry skin and has poor duration
Solution Approach 1:
The patent creates a composite formulation that combines cosmetic powders with hygroscopic polymers and plasticizers. This composite structure provides both the compact solid form for easy transport and the necessary moisturizing properties for comfortable application and long duration on skin, particularly for dry skin types.
Solution Approach 2:
The patent adjusts the chemical composition parameters to include humectants (glycerol, propylene glycol) and film-forming polymers that enhance both the physical properties for portability and the cosmetic performance for duration and comfort on skin.
4Volume of moving object
If compact cosmetic products are made solid to reduce space occupation, then portability is improved, but homogeneous pick up becomes impossible due to breaking that produces dust and fragments
Solution Approach 1:
The patent changes the mechanical properties of the cosmetic product by incorporating polymers and plasticizers in optimized ratios, transforming it from a brittle material that produces dust and fragments to a flexible material that maintains structural integrity during application, enabling homogeneous pick up.
Solution Approach 2:
The patent creates a flexible solid structure that can be evenly applied without breaking. The flexible polymer matrix prevents the product from shattering into dust and fragments, allowing for smooth, homogeneous application to the skin.
