Silicate Modified Starches for Personal Care Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an alternative to organically modified starches that are expensive to prepare and require the addition of inorganic salts for functionalization, while providing aesthetic benefits such as smoothness, creaminess, and non-sticky or non-oily properties in personal care formulations.
Innovation Solution
The use of starches modified with silicates or siliconates, which are compatible with various skin care ingredients and provide aesthetic enhancements by maintaining their granular structure, allowing for the creation of safe and inexpensive derivatives that can be incorporated into personal care formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If organically modified starches are used to provide aesthetic benefits in personal care formulations, then smoothness and creaminess are improved, but preparation cost increases and inorganic salts are required for functionalization
Solution Approach 1:
The invention changes the chemical parameters of starch by modifying it with silicates or siliconates instead of organic modifiers. This substitution alters the chemical composition and structure of the starch, enabling it to provide aesthetic benefits without requiring expensive organic modification processes or additional inorganic salts for functionalization
Solution Approach 2:
The invention replaces expensive organically modified starches with cheaper silicate or siliconate modified starches. The silicate/siliconate modification process is more cost-effective and eliminates the need for expensive organic reagents and subsequent inorganic salt additions, providing a economical alternative that maintains aesthetic functionality
2Ease of manufacture
If silicate or siliconate modified starches are used to enhance aesthetic properties, then smoothness and creaminess are improved, but the formulation may cause cloudiness or flaking
Solution Approach 1:
The invention optimizes the degree of silicate or siliconate modification to achieve the right balance between aesthetic benefits and formulation stability. By controlling modification parameters such as silicate/siliconate concentration, reaction time, and temperature, the starch achieves improved smoothness and creaminess without excessive modification that would cause cloudiness or flaking
Solution Approach 2:
The invention applies partial modification of starch with silicates or siliconates rather than complete modification. This partial action approach ensures that enough starch structure remains intact to maintain formulation clarity and prevent flaking, while sufficient modification occurs to provide the desired aesthetic benefits of smoothness and creaminess

AI summary
The present invention details the use of starch silicate and starch siliconates in personal care formulations to enhance or provide aesthetic properties to skin care products. These properties can range from smoothness and silky feel to non-greasy and non-oily. These starch derivatives provide an alternative to organically modified starches which can be expensive to prepare and require the addition of inorganic salts to functionalize the reagents.
