Solution Overview

Problem

Existing makeup remover compositions struggle to effectively remove long-wear or transfer-resistant makeup compositions from keratinous materials, particularly when different types of film-forming agents are used, as they tend to form difficult-to-remove films.

Innovation Solution

A three-part makeup remover composition comprising a water part with a plasticizing agent, an oil part substantially free of silicone oils, and a silicone-in-water emulsion part with aminated silicone, which are mixed to temporarily blend and then applied to the applied makeup composition for removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If film forming agents are incorporated into makeup compositions to provide long wear and transfer-resistance properties, then the durability and transfer-resistance of makeup are improved, but the ease of removal of makeup deteriorates

Engineering Contradiction:
Improvedurability and transfer-resistance of makeupVSAvoidease of removal of makeup
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The makeup remover composition is divided into three distinct parts that work synergistically: (a) water part with plasticizing agent to soften and dissolve film formers, (b) oil part to dissolve oil-soluble film forming agents and waxes, and (c) silicone-in-water emulsion part to address water-soluble film-formers and resins. This segmentation allows each component to target specific types of film forming agents, making the removal of long-wear makeup effective without requiring a single complex formulation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple types of film forming agents are included in makeup compositions to achieve long wear properties, then the durability of makeup is improved, but the difficulty of detecting and measuring removal effectiveness increases

Engineering Contradiction:
Improvedurability of makeupVSAvoiddifficulty of measuring removal effectiveness
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

Each part of the makeup remover composition is specifically designed with targeted properties to address different types of film forming agents. The water part with plasticizing agents specifically targets certain polymers, the oil part targets waxes and oil-soluble agents, and the silicone-in-water emulsion targets resins. This local quality approach ensures that each component contributes uniquely to removing specific film formers, making the overall removal process more measurable and effective.

Inventive Principle:
Principle #3Local quality

3Device complexity

If traditional two-phase compositions are used for makeup removal, then the simplicity of the composition is maintained, but the effectiveness of removing transfer-resistant makeup deteriorates

Engineering Contradiction:
Improvesimplicity of compositionVSAvoideffectiveness of removing transfer-resistant makeup
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The invention creates a composite three-part system that combines water-soluble, oil-soluble, and silicone-based components in a unified composition. This composite approach integrates multiple removal mechanisms (plasticization, dissolution, emulsification) into a single product that maintains relative simplicity in application while significantly improving effectiveness against transfer-resistant makeup compared to traditional two-phase compositions.
