Solution Overview

Problem

Existing oil-based cosmetic products, particularly skincare products, face challenges in achieving a natural formula without ethoxylated emulsifiers and microplastics while maintaining the blooming effect and avoiding greasy residues, and are limited in their applicability to various oils.

Innovation Solution

A composition comprising a specific combination of polyglyceryl-3 dioleate, polyglyceryl-3 polyricoleate, and polyglyceryl-2 laurate emulsifiers, which form a clear homogeneous blend that spontaneously emulsifies upon contact with water, eliminating greasy residues and being applicable to a wide range of oils.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ethoxylated emulsifiers are used to achieve blooming effect and prevent greasy residue, then emulsifying performance is improved, but skin irritation and environmental harm increase

Engineering Contradiction:

Improveemulsifying performanceVSAvoidskin irritation and environmental harm

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by replacing ethoxylated emulsifiers with a specific combination of polyglycerol esters (polyglyceryl-3 dioleate, polyglyceryl-3 polyricoleate, and polyglyceryl-2 laurate) in defined proportions. This parameter change maintains emulsifying performance while eliminating harmful effects associated with ethoxylated compounds.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses a composite emulsifying system comprising multiple polyglycerol esters working together synergistically. This composite approach replaces single-component ethoxylated emulsifiers with a multi-component natural alternative that achieves comparable or superior emulsifying performance without the harmful effects.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If natural polyglycerol ester combination is used to replace ethoxylated emulsifiers, then harmful effects are reduced, but emulsifying performance may be compromised

Engineering Contradiction:

Improveelimination of harmful substancesVSAvoidemulsifying performance

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent optimizes the concentration parameters of each polyglycerol ester component to ensure adequate emulsifying performance. By controlling the ratio and amount of each ester in the composition, the patent maintains reliable emulsifying action while using only natural, non-harmful substances.

Inventive Principle:

Principle #35Parameter changes

3Manufacturing precision

If a specific combination of polyglycerol esters is used to achieve clear homogeneous blend and spontaneous emulsification, then product quality is improved, but formulation complexity increases

Engineering Contradiction:

Improveproduct quality and homogeneityVSAvoidformulation complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent divides the emulsifying function into three specific polyglycerol ester components, each contributing a particular function to the overall emulsification process. This segmentation allows for precise control over the emulsification mechanism and ensures consistent product quality while maintaining relatively simple formulation.

Inventive Principle:

Principle #1Segmentation

AI summary

The present application relates to an emulsifying composition comprising polyglyceryl-3 dioleate, polyglyceryl-3 polyricoleate and polyglyceryl-2 laurate, and to oil-based composition comprising said emulsifying composition. Oil-based cosmetic products comprising an oil and the specific combination of polyglycerol esters form a clear homogeneous blend and spontaneously emulsify upon contact with water. They exhibit no greasy effect after rinsing of the oil-based cosmetic product.
