Aerated Solid Cosmetic Composition with Dispersed Gas Bubbles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Massage bars used in professional settings pose hygiene concerns due to the inability to reuse them safely across multiple clients, and breaking them into smaller pieces can result in uneven edges and a less pleasant massage experience.
Innovation Solution
A solid cosmetic product is developed with dispersed gas bubbles, forming at least 20% of its volume, created by melting vegetable butters and applying pressure reduction to form bubbles, which reduces the product's density and allows for a larger size without waste while maintaining a pleasant massage experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a single solid massage bar is used for multiple recipients, then product waste is reduced, but hygiene requirements are violated
Solution Approach 1:
The massage bar is segmented into multiple individual portions through a scored surface that allows clean separation. Each portion can be independently broken off along the score lines, ensuring that only a single-use portion contacts each recipient while the remainder of the bar remains intact and hygienic for subsequent uses.
2Reliability
If a massage bar is broken into smaller pieces for single use, then hygiene requirements are met, but the physical sensation deteriorates due to rough edges
Solution Approach 1:
The surface of the massage bar is pre-scored with shallow grooves that guide the breaking process. These pre-formed score lines ensure that when a portion is broken off, it separates cleanly along the predetermined path rather than fracturing unpredictably, thereby maintaining smooth edges and comfortable texture for the massage portion.
3Quantity of substance
If a large sized massage bar is provided, then single use portions can be obtained, but product waste increases due to inability to use remaining portions
Solution Approach 1:
The large massage bar is divided into multiple equal-sized portions through scoring, allowing the user to break off exactly one portion per recipient. This eliminates waste of the remaining portions since each can be used in subsequent sessions with different recipients, while still providing the convenience of single-use portions for hygiene compliance.
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 aerated solid cosmetic product provides a lighter, more enjoyable massage experience while minimizing waste and ensuring hygiene by allowing for single-use applications without the need for external packaging.
Implementation Method 1
applying a pressure reduction to the melted butter such that gas bubbles are formed within the melted one or more vegetable butters
Implementation Method 2
allowing the mixture of step ii) to solidify
