Oil-Absorbable Organic Particle Emulsion for Matte Texture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic products struggle to provide long-lasting matte effects without imparting stickiness or a less smooth texture, and existing oil-absorbable powders have insufficient oil-absorption capacity and can cause a squeaky texture.
Innovation Solution
A composition in the form of an emulsion containing oil-absorbable organic particles with high oil-absorbing capacity and small particle size, combined with oil, emulsifier, and water, optionally with additional oil-absorbable particles, to achieve long-lasting matte effects and smooth texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If hard resins or polymers are used to maintain immediate matte effects, then the lastingness of matte effects is improved, but the texture becomes sticky or less smooth
Solution Approach 1:
The invention changes the particle size parameter of oil-absorbable particles to less than 30 μm (preferably 8-12 μm) and uses organic particles with specific oil-absorbing capacity (180-400 ml/100g). This parameter optimization allows the particles to provide long-lasting matte effects without the stickiness associated with hard resins or polymers, resolving the contradiction between duration and texture smoothness.
2Quantity of substance
If oil-absorbable powders are used to provide immediate matte effects, then the oil-absorption capacity is improved, but a squeaky texture is generated due to powder particle contact
Solution Approach 1:
The invention changes the particle size parameter to less than 30 μm and specifies organic particle materials with oil-absorbing capacity of 180-400 ml/100g. These fine organic particles absorb oil effectively without the squeaky texture caused by larger inorganic powder particles, resolving the contradiction between oil-absorption capacity and texture quality.
3Ease of operation
If conventional cosmetic products are used in hot and humid conditions, then immediate matte effects are provided, but the effects do not last for a long period of time
Solution Approach 1:
The invention uses a composite formulation combining fine organic oil-absorbable particles (less than 30 μm with high oil-absorbing capacity) in an emulsion system. This composite approach provides both immediate matte effects upon application and long-lasting performance in hot and humid conditions, resolving the contradiction between immediate effect quality and duration.
