Abradable Glitter Preparation Using Platelet Particles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dosage forms for luster pigments fail to apply a homogeneous film with a glitter effect on flat substrates while maintaining adhesive properties, as particulate solids tend to sediment in liquid preparations or form uneven films in solid preparations, and existing water-based adhesive preparations lose their optical effect due to corrosion.
Innovation Solution
A dimensionally stable, water-based preparation with a translucent carrier mass containing C12 to C22 fatty acids and platelet-shaped solid particles of 2-40 μm diameter, which provides a controlled, uniform application and maintains the glitter effect through a combination of fatty acids, starch ethers, and layered inorganic materials protected by plastic layers, ensuring adhesive properties and resistance to corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If particulate solids are used in liquid preparations to achieve glitter effect, then the glitter effect is visible, but the particulate solids sediment and cannot be applied evenly
Solution Approach 1:
The patent changes the physical state parameter of the preparation from liquid to dimensionally stable (semi-solid) form, which prevents sedimentation of platelet-shaped particles while maintaining their ability to be rubbed onto substrates. This parameter change resolves the contradiction by eliminating the sedimentation issue that prevented homogeneous application.
Solution Approach 2:
The patent creates a composite preparation combining platelet-shaped solid particles (2-40 μm) with a dimensionally stable carrier system containing fatty acids and starch ethers. This composite structure allows the particles to remain suspended and evenly distributed while maintaining the formulation's stability and adhesion properties.
2Illumination intensity
If platelet-shaped solid particles of 2-40 μm are used for glitter effect, then the glitter effect is clearly perceptible, but the preparation loses adhesive properties
Solution Approach 1:
The patent formulates a composite system where platelet-shaped particles are embedded in a carrier matrix containing adhesive components (fatty acids and starch ethers). This composite structure allows the particles to provide glitter effect while the carrier matrix maintains adhesive strength for bonding porous substrates.
Solution Approach 2:
The patent assigns different functions to different components: the platelet-shaped particles provide optical glitter effect, while the fatty acids and starch ethers in the carrier provide adhesion. This local quality differentiation resolves the contradiction by allowing each component to optimize its specific function without compromising the other.
3Strength
If water-based adhesive preparations are used for bonding, then adhesive properties are achieved, but the optical effect is lost due to corrosion of pigments
Solution Approach 1:
The patent uses platelet-shaped particles made of inorganic materials (such as mica, metal oxides, or other corrosion-resistant substances) that are inherently resistant to water-based corrosion. These particles maintain their optical properties throughout the adhesive's service life, resolving the contradiction between water-based adhesion and optical effect retention.
4Ease of operation
If solid preparations are used to apply particulate solids, then a film can be rubbed off, but the film is not homogeneous and not thinnest possible
Solution Approach 1:
The patent optimizes the consistency and rheological parameters of the dimensionally stable preparation to enable it to be rubbed into a thin, homogeneous film. The specific formulation with fatty acids and starch ethers provides the right balance of stability and rub-off properties, resolving the contradiction between ease of application and film quality.
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 preparation achieves a homogeneous glitter effect with excellent compressive strength and abrasion properties, allowing for uniform application and bonding of flat substrates while maintaining the optical effect and adhesive properties, even after storage.
Implementation Method 1
Due to their reflection properties compared to visible light, the pigments applied in the designed area produce a glossy effect, which causes light reflections to appear in the designed area when the relative position of the paper surface to the incident light changes. The viewer perceives the multitude of light reflections during such a relative change in position as a glittering effect.
Implementation Method 2
preparations according to the invention have adhesive properties, so that the abraded film is ideally suited for attaching flat decorative elements or generally for bonding flat, porous materials

AI summary
The invention relates to a dimensionally stable preparation which can be abraded on flat materials, containing a translucent water-based polymer-containing carrier composition and platelet-shaped solid particles. The platelet-shaped solid particles have an average maximum diameter ranging from 2 to 40 µm and are contained in the preparation in a proportion by volume specified by the selected particle size in order to achieve a sheen which is clearly perceptible to the human eye while simultaneously having good abrasion properties. In a sub-aspect of the invention, the preparations according to the invention further have adhesive properties such that the abraded film is best suited for securing flat decorative elements or generally for adhering flat porous materials.
