Powder Essence Composition Phase Change Hydration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder essence compositions fail to provide a natural, long-lasting water-color tone and a light, hydrated skin feel, often resulting in a cakey or sticky texture, especially when reapplied.
Innovation Solution
A water-resistant powder essence composition comprising silica dimethicone silylate, water, glycerine, phenoxy ethanol, glycosyl trehalose, hydrogenated starch hydrolysate, methylparaben, silica, methicone, squalane, betaine, arbutin, adenosine, and trehalose, which transforms into a liquid upon skin contact, maintaining clear color and providing a non-sticky, hydrated skin feel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional powder essence compositions are used, then the powder form provides protection for unstable functional ingredients, but the composition delivers unclear color and creates a heavy, cakey feeling on the skin
Solution Approach 1:
The patent changes the physical and chemical parameters of the powder essence by using silica dimethicone silylate with specific surface area (50-200 m²/g) and pore volume (0.05-0.2 mL/g), along with controlling water content (40-70%) and pigment distribution, to achieve both ingredient stability and a light, non-cakey texture with clear water-color tone
Solution Approach 2:
The patent creates a composite powder essence system combining silica dimethicone silylate as the core material with water, pigments, and functional ingredients, where the composite structure provides both protection for unstable ingredients and delivers clear color with a light skin feel
2Illumination intensity
If more pigments are added to achieve stronger color tone, then the coloring function is improved, but the composition becomes sticky and stuffy on the skin
Solution Approach 1:
The patent applies local quality by distributing pigments non-uniformly within the powder essence composition, with higher pigment concentration at certain locations and lower at others, allowing strong color tone in some areas while maintaining light and non-sticky texture in other areas, achieving water-color effect
3Illumination intensity
If the powder essence is reapplied multiple times to enhance color, then the coloring function is improved, but the composition gets cakey on the skin
Solution Approach 1:
The patent introduces dynamics by making the powder essence transform from powder state to liquid state upon contact with skin moisture, allowing the composition to adapt to reapplication scenarios where it maintains fluidity and integrates smoothly without becoming cakey, ensuring consistent texture across multiple applications
4Quantity of substance
If water content is increased to improve skin hydration, then the skin feeling is improved, but the composition loses water resistance and smears easily
Solution Approach 1:
The patent uses silica dimethicone silylate with specific pore structure and surface properties as a flexible framework that can hold water for hydration while the hydrophobic characteristics of the silylete provide a thin film effect that prevents water from penetrating through, achieving both hydration and water resistance simultaneously
Solution Approach 2:
The patent utilizes the porous structure of silica dimethicone silylate with controlled pore volume (0.05-0.2 mL/g) to trap and retain water molecules within the pores, providing sustained hydration while the overall hydrophobic nature of the material maintains water resistance and prevents smearing
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 composition delivers a high-fitting, long-lasting natural color tone without smearing, keeps the skin light and hydrated, and prevents cakeiness even with repeated applications, while maintaining a water-resistant effect.
Implementation Method 1
the powder essence composition takes the form of powder before use and turns into liquid the moment it is rubbed on the skin
Implementation Method 2
the particulates surround each water droplet and sequester it from the other particulate surrounded water droplets

AI summary
The present invention relates to a long-lasting powder essence composition with improved coloring and skin feeling and its preparation method. The powder essence composition is a high-fitting coloring powder not likely to smear or wear off. The composition turns into liquid the moment it is rubbed on the skin to offer a natural color tone like water color, keeps the color clear without getting cakey even when it is reapplied multiple times, and delivers a clearer color as it glides on the skin to break powder and water particles. The powder essence composition according to the present invention is also a powder emulsion, which makes the skin feel light and hydrated rather than sticky or stuffy when applied to the skin and stays long due to its water-resistant function. In addition, the powder essence composition according to the present invention contains different functional moisturizing agents to provide plenty of nourishment when applied to the skin. The composition makes the skin feel fresh and hydrated rather than stuffy or heavy, lightly sinks into the skin like nothing is applied on the skin, to display a strong tint function, stays long just with one touch and has a good water-resistant effect, so it does not bleed when in contact with water.
