Coconut Oil Modeling Composition for Skin Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional modeling compositions, such as clay and oil clay, cause skin problems and are harmful to users, especially children, due to the use of materials like phthalate plasticizers and borate, and suffer from issues like cracking, crumbling, and difficulty in coloring, while also being environmentally unfriendly.
Innovation Solution
A modeling composition comprising 5-20 wt % coconut oil, 5-10 wt % carboxymethyl cellulose, 1-10 wt % squalane, 1-5 wt % lecithin, 20-30 wt % ozokerite, and 30-60 wt % starch, along with optional additives like sorbitan fatty acid ester, natural oils, and a mixture of water and polyethylene vinyl acetate, which provides moisturizing effects and is environmentally friendly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional modeling compositions use phthalate plasticizers and borate, then formability and workability are improved, but skin safety and environmental friendliness deteriorate
Solution Approach 1:
The patent removes harmful substances (phthalate plasticizers and borate) from the modeling composition formula and replaces them with safe alternatives. Specifically, it uses natural oils (coconut oil, olive oil, almond oil), natural waxes (beeswax, carnauba wax), and water-soluble polymers (carboxymethyl cellulose, polyvinyl alcohol) to achieve the desired plasticizing and binding effects without skin irritation or environmental harm.
Solution Approach 2:
The patent substitutes expensive or harmful chemical plasticizers with inexpensive, natural, and biodegradable materials. The use of natural oils, waxes, and starch-based components provides the necessary plasticity and workability while being environmentally friendly and safe for skin contact, especially for children's use.
2Weight of moving object
If natural polymer clay is used to reduce weight, then transportability is improved, but structural stability deteriorates causing cracking and crumbling
Solution Approach 1:
The patent creates a composite modeling composition by combining multiple materials with complementary properties. It mixes water-soluble polymers (carboxymethyl cellulose, polyvinyl alcohol) for lightweight and flexible characteristics with natural waxes (beeswax, carnauba wax) and oils for structural reinforcement. This composite approach achieves both low weight and high structural stability, preventing cracking and crumbling during drying.
Solution Approach 2:
The patent optimizes the ratios and concentrations of different components to achieve the desired balance between weight and strength. By carefully controlling the amounts of water-soluble polymers, natural waxes, oils, and starch, the formulation achieves lightweight properties while maintaining sufficient structural integrity during the drying process and after hardening.
3Reliability
If inorganic clay is used for high specific gravity, then durability is improved, but ease of transport and handling deteriorates
Solution Approach 1:
The patent removes inorganic clay components (such as kaolin, ball clay) from the formulation and replaces them with organic, lightweight alternatives. It uses starch, cellulose derivatives, and natural polymers as the base material, which significantly reduce the specific gravity and weight of the clay while maintaining workability and durability through the addition of binding agents and plasticizers.
Solution Approach 2:
The patent creates a lightweight composite material by combining organic polymers (starch, carboxymethyl cellulose, polyvinyl alcohol) with natural waxes and oils. This composite structure provides both the low weight needed for easy transport and the durability required for lasting models, eliminating the need for heavy inorganic clay while maintaining structural integrity.
4Productivity
If modeling composition dries quickly for efficient production, then productivity is improved, but skin moisture retention deteriorates causing dry skin and rash
Solution Approach 1:
The patent converts the typically harmful effect of quick drying (which causes skin dryness and irritation) into a beneficial outcome by incorporating moisturizing ingredients. The formulation includes coconut oil, olive oil, almond oil, beeswax, and carnauba wax, which provide continuous moisture to the skin during and after the drying process. These ingredients ensure that even as the clay dries efficiently, the user's skin remains hydrated and protected, preventing rash and irritation.
Solution Approach 2:
The patent makes the modeling composition multi-functional by combining modeling properties with skin care benefits. The natural oils and waxes serve dual purposes: they act as plasticizers and binders for the clay formulation while simultaneously providing moisturizing and protective effects on the user's skin. This eliminates the need for separate skin care products and makes the modeling activity itself beneficial for skin health.
