Solution Overview

Problem

Current personal care compositions fail to effectively reduce the visibility of skin imperfections such as wrinkles, age spots, and pore visibility, while also addressing shine and uneven skin tone, which are concerns for maintaining a youthful appearance.

Innovation Solution

A personal care composition comprising a porous particle with high oil absorption capacity and a crosspolymer comprising adipic acid and neopentyl glycol, which works synergistically to absorb oils and reduce pore visibility, combined with optional silicone elastomers, organic sunscreens, and skin lightening agents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If inorganic particulates such as talc, silica, and kaolin are used to achieve a matte effect, then skin shine is reduced, but the composition fails to effectively reduce pore visibility and skin imperfections

Engineering Contradiction:
Improveskin shineVSAvoidpore visibility reduction
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The patent employs porous particles with controlled pore structures that can absorb excess sebum while maintaining light-scattering properties. The porous structure provides both oil absorption capability and optical blurring effect, simultaneously addressing shine reduction and pore visibility concerns without relying solely on traditional inorganic fillers

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The invention combines porous particles with crosspolymers comprising adipic acid and neopentyl glycol to create a composite system. This composite approach integrates the oil-absorbing properties of porous materials with the film-forming and blurring capabilities of crosspolymer networks, achieving synergistic effects that neither component can accomplish alone

Inventive Principle:
Principle #40Composite materials

2Shape

If traditional inorganic particulates are used for masking skin imperfections, then a matte appearance is achieved, but the composition lacks long-lasting optical effects and fails to even out skin tone

Engineering Contradiction:
Improvematte appearanceVSAvoidlong-lasting optical effect
Core Design Contradiction:
ShapeVSDuration of action of stationary object

Solution Approach 1:

The crosspolymer component forms a flexible film network on the skin surface that traps and holds porous particles in place. This film structure provides sustained optical blurring effects and extends the duration of the matte appearance, preventing premature degradation or displacement of the active ingredients

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The crosspolymer serves multiple functions: it acts as a thickening agent, forms a film matrix for ingredient delivery, provides inherent blurring effects, and extends the wear time of the composition. This multi-functionality addresses both appearance quality and duration without requiring separate additives

Inventive Principle:
Principle #6Universality (Multi-functionality)
