Hydroxypropyl Starch Phosphate Cosmetic Oil Substitute
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a substitute for mineral and silicone oils in cosmetic preparations that maintains sensory properties such as spreadability and absorbability, while being free from animal-derived ingredients and polyacrylates, to meet the growing demand for 'natural' and 'vegan' products.
Innovation Solution
A mixture of hydroxypropyl starch phosphate and vegetable oils is used as a substitute for mineral and silicone oils in cosmetic preparations, with a preferred weight ratio of 2:1 to 1:20, and optionally including esters of caprylic and capric acid, emulsifiers, and other ingredients to create a vegan, animal-free, and aesthetically pleasing emulsion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mineral oils and silicone oils are used in cosmetic preparations, then sensory properties such as spreadability and absorbability are improved, but the products contain animal-derived ingredients and are not considered 'natural' or 'vegan'
Solution Approach 1:
The patent changes the chemical composition parameters by replacing mineral and silicone oils with a specific mixture of hydroxypropyl starch phosphate and vegetable oils. This parameter change maintains the desired sensory properties while eliminating animal-derived ingredients and achieving 'natural' and 'vegan' status.
Solution Approach 2:
The patent creates a composite material system by combining hydroxypropyl starch phosphate with vegetable oils in specific ratios. This composite approach allows the formulation to achieve both the required sensory properties and the 'natural/vegan' criteria that cannot be met by single ingredients alone.
2Object-affected harmful factors
If xanthan gum is used instead of polyacrylates, then the preparation becomes more natural, but whitening occurs and stringy texture appears
Solution Approach 1:
The patent extracts and removes xanthan gum from the formulation entirely, replacing it with hydroxypropyl starch phosphate. This extraction eliminates the source of whitening and stringy texture problems while maintaining the desired natural appearance.
Solution Approach 2:
The patent changes the thickening agent parameter from xanthan gum to hydroxypropyl starch phosphate, which has different rheological properties that prevent whitening and stringy texture formation while maintaining natural aesthetics.
3Object-affected harmful factors
If vegetable oils are used as substitutes for mineral and silicone oils, then the products become vegan and natural, but sensory properties such as spreadability and absorbability deteriorate
Solution Approach 1:
The patent creates a composite material system combining hydroxypropyl starch phosphate with vegetable oils in specific ratios. This composite approach allows the formulation to achieve both vegan status and acceptable sensory properties, as the combination compensates for the limitations of individual ingredients.
Solution Approach 2:
The patent optimizes the concentration parameters of hydroxypropyl starch phosphate and vegetable oils to achieve the desired balance between vegan compliance and sensory performance. By adjusting these parameters, the formulation maintains absorbability and spreadability while being fully vegan.
