Solution Overview

Problem

Existing skin care products are often incompatible with colorant cosmetics, leading to undesirable effects such as irritation, clogged pores, and a lack of uniform visual appearance, especially when applied on dry or weathered skin.

Innovation Solution

The development of cosmetically acceptable skin-moisturizing compositions comprising phospholipid-stabilized submicron triglyceride particles and botanical materials, which can be applied before, with, or after colorant cosmetics, to provide moisturization and enhance the cosmetic effect without interfering with the desired visual appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If aqueous skin care products containing moisturizer ingredients are applied to the skin, then skin moisturization is improved, but compatibility with colorant cosmetics deteriorates and visual cosmetic appearance is adversely affected

Engineering Contradiction:
Improveskin moisturizationVSAvoidcompatibility with colorant cosmetics
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the physical parameters of the moisturizing composition by using submicron particle size (0.1-10 micrometers) and specific viscosity ranges (10-1000 cP), allowing the product to provide moisturization while maintaining compatibility with colorant cosmetics. The submicron size enables penetration and moisturization without creating a barrier that would interfere with cosmetic application.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates a composite emulsion system combining aqueous and oleaginous phases with specific surfactant combinations (nonionic and anionic surfactants) to achieve both moisturization and cosmetic compatibility. The composite structure allows the product to function as both a moisturizer and a compatible base for colorant cosmetics.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If oily or greasy foundation products are applied to the skin before colorant cosmetic to overcome incompatibility, then compatibility is improved, but skin irritation and pore clogging increase

Engineering Contradiction:
Improvecompatibility with colorant cosmeticsVSAvoidskin irritation and pore clogging
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses lightweight oils with specific molecular weight ranges and submicron particle sizes to provide compatibility without the heavy, occlusive properties of traditional oily foundations. The viscosity is controlled at 10-1000 cP to ensure spreadability without excessive oiliness, reducing skin burden while maintaining cosmetic compatibility.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses specific surfactants as intermediary substances that mediate between the skin and colorant cosmetics. The nonionic and anionic surfactants create a compatible interface that allows cosmetic application without requiring heavy oily bases, thus avoiding pore clogging while maintaining compatibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If multiple coats of colorant cosmetic are applied to achieve uniform appearance on dry skin, then visual uniformity is improved, but skin irritation and cosmetic failure increase

Engineering Contradiction:
Improvevisual uniformityVSAvoidcosmetic performance stability
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent applies moisturizing action before cosmetic application by using a lightweight emulsion that prepares the skin surface in advance. The submicron particles and specific oil phases pre-hydrate the skin, creating a uniform base that allows single-coat cosmetic application without the need for multiple layers, thereby preventing cosmetic failure.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If substantially anhydrous colorant cosmetic is applied to non-moisturized skin, then cosmetic application is simplified, but desired visual effect and uniformity are not achieved

Engineering Contradiction:
Improvecosmetic application simplicityVSAvoidvisual effect uniformity
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent merges the moisturizing function and cosmetic base function into a single product that can be used with anhydrous cosmetics. The emulsion combines aqueous and oleaginous phases with submicron triglyceride particles to create a unified system that provides both hydration and a compatible application base, simplifying the overall routine while ensuring uniform visual effect.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Skin care emulsion compositions are disclosed comprising an oil-in-water emulsion comprising phospholipid-stabilized, submicron triglyceride particles, botanical material selected from the group consisting of a vegetal material, a marine material and combinations thereof; a polycarboxylate polymer and a phosphate ester-type emulsifier. The skin care compositions can be topically applied to the skin before, and surprisingly, together with, and/or after applying a skin colorant (i.e., pigmented) cosmetic composition to moisturize the skin and achieve, augment, and/or maintain a visibly desirable cosmetic appearance.
