Solution Overview

Problem

Existing color particles used in cosmetics and food products are unstable in aqueous matrices, tend to bleed or dissolve over time, and may be perceived as foreign bodies by consumers, while also facing challenges in production due to viscosity issues during extrusion.

Innovation Solution

The development of color particles comprising an extrudate with a carbohydrate matrix of starch having at least 80% amylopectin content, combined with a viscosity modifying component, an emulsifier, water, and optional colorants or flavorings, which are produced through an extrusion process to create stable, non-dissolving, and visually appealing particles suitable for use in oral hygiene products, dairy products, and cleaning agents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If natural-based particles (e.g., carbohydrate matrices) are used as alternatives to plastic microbeads, then health and environmental safety is improved, but stability in aqueous matrices deteriorates (particles tend to bleed or dissolve over time)

Engineering Contradiction:
Improvehealth and environmental safetyVSAvoidstability in aqueous matrices
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The patent modifies the carbohydrate matrix by controlling the amylose-to-amylopectin ratio (specifically using starch with ≥80% amylopectin content) and adjusting cross-linking density to optimize both biodegradability and stability in aqueous environments. This parameter optimization allows the particles to maintain structural integrity while remaining environmentally safe.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates composite particles by combining carbohydrate matrices with controlled amylose/amylopectin ratios and incorporating cross-linking agents. This composite structure provides both the environmental safety of natural materials and the stability needed to prevent bleeding or dissolving in aqueous product matrices.

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If starch with high amylopectin content (≥80%) is used in the extrusion process, then producibility and stability are improved, but viscosity control during extrusion becomes more challenging

Engineering Contradiction:
Improveproducibility through extrusionVSAvoidviscosity control during extrusion
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent specifies using starch with a controlled amylose-to-amylopectin ratio (≥80% amylopectin) which fundamentally changes the rheological properties of the extrusion material. This parameter control enables consistent extrusion performance and particle stability while managing viscosity characteristics through precise starch selection.

Inventive Principle:
Principle #35Parameter changes

3Duration of action of stationary object

If color particles are made stable and non-dissolving, then product shelf life is improved, but consumer perception may worsen (particles perceived as foreign bodies)

Engineering Contradiction:
Improveshelf life stabilityVSAvoidconsumer acceptance
Core Design Contradiction:
Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent uses naturally occurring starch components (amylose and amylopectin) in specific ratios to create particles that are both stable and biologically familiar. The high amylopectin content (≥80%) creates a matrix that is stable yet naturally perceived, avoiding the foreign body effect while maintaining shelf life stability.
