Phospholipid-Stabilized Submicron Triglyceride Emulsion for Cosmetic Compatibility
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
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
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.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The skin care compositions effectively moisturize and soothe the skin, maintaining a smooth and soft appearance while being compatible with both aqueous and anhydrous colorant cosmetics, enhancing their longevity and visual appeal.
Implementation Method 1
The compositions are applied to, and left on, the skin of the face and body... an oil-in-water emulsion comprising phospholipid-stabilized submicron triglyceride particles
Implementation Method 2
phospholipid-stabilized submicron triglyceride particles... an effective emulsifying amount of a phosphate ester-type emulsifier
Data Source
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.
