Liquid Crystal Cosmetic Composition with Elastic Texture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal cosmetic formulations lack diversity and stability, particularly in achieving a high-hardness, elastic texture with a moisture feeling, due to insufficient use of viscosity modifiers and oil content.
Innovation Solution
A liquid crystal cosmetic composition comprising 5-10 parts by weight of a liquid crystal former and 0.05-1 part by weight of a viscosity modifier combination, specifically acrylate/C10-C30 alkyl acrylate crosspolymer and carbomer, mixed with an aqueous phase to create a stable, high-hardness formulation with an elastic texture and improved moisture feeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If general O/W emulsified cream formulations are used, then the formulation is simple to prepare, but the formulation diversity and stability are insufficient
Solution Approach 1:
The patent combines liquid crystal formers (higher aliphatic alcohols, nonionic surfactants, and/or oils) with viscosity modifiers (acrylate crosspolymers and carbomers) to create a composite liquid crystal cosmetic composition. This composite approach enables diverse formulations including high-hardness types, elastic types, and moisture-giving types, while maintaining preparation simplicity through the self-organizing properties of liquid crystals.
2Strength
If high oil content is used to achieve high-hardness texture, then the hardness increases, but the liquid crystal structure disappears over time and formulation stability is damaged
Solution Approach 1:
The patent optimizes the oil phase content to 5-20 parts by weight per 100 parts of total composition, which is sufficient to achieve high-hardness texture (50-150 dyne/cm²) while maintaining liquid crystal structure stability. This parameter optimization prevents oil phase separation and liquid crystal structure disappearance, resolving the contradiction between hardness and stability.
Solution Approach 2:
The patent introduces viscosity modifiers (acrylate/C10-C30 alkyl acrylate crosspolymer and carbomer) as intermediary substances that enhance the hardness and elastic texture of the liquid crystal formulation without requiring high oil content. These modifiers act as mediators that provide structural support and stability, enabling high-hardness texture with only 5-20 parts oil per 100 parts total composition.
3Strength
If viscosity modifier content is increased to improve texture, then the elastic texture improves, but the moisture feeling is reduced
Solution Approach 1:
The patent optimizes the viscosity modifier content to 0.05-5 parts by weight per 100 parts of total composition, with the acrylate crosspolymer at 0.05-2 parts and carbomer at 0.05-3 parts. This optimized range provides sufficient elastic texture while maintaining moisture feeling, as evidenced by the moisture-giving liquid crystal cosmetic composition type that contains additional moisturizing ingredients.
4Stability of the object's composition
If liquid crystal former content is increased to achieve liquid crystal formation, then the liquid crystal structure is formed, but the oil phase proportion becomes too high and liquid crystal structure disappears over time
Solution Approach 1:
The patent optimizes the liquid crystal former components (higher aliphatic alcohols C12-C22, nonionic surfactants, and/or oils) to contain 5-50 parts by weight per 100 parts of total composition, with the oil phase specifically controlled at 5-20 parts. This parameter optimization ensures liquid crystal structure formation and stability while preventing oil phase separation and structure disappearance over time.

Implementation Method 1
a liquid crystal is in an intermediate state between a solid and a liquid and generally refers to a system having a lamellar structure formed in which, in organic molecules that have hydrophilic parts and lipophilic parts at the same time, the hydrophilic parts are arranged with each other in a uniform manner, and the lipophilic parts are arranged with each other in a uniform manner to form a plurality of layers
Implementation Method 2
a viscosity modifier at a content of 0.05 parts by weight to 1 part by weight
