Paste Deodorant Composition for Smooth Glide and Shelf Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deodorant compositions, particularly stick deodorants, face challenges in achieving desirable properties such as body integrity, glide without sticking to hair, suitable melting point, and shelf stability, especially when using natural ingredients, and often struggle with high powder content affecting glide.
Innovation Solution
Formulations comprising at least 95% natural or naturally-derived ingredients, including beeswax, coco-caprylate, shea butter, and coconut oil, with specific ratios and combinations of emollients, waxes, and starches, along with optional deodorant agents, are developed to enhance glide and stability, avoiding silicones and aluminum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high powder content is used in stick deodorant, then deodorant efficacy is improved, but glide performance deteriorates
Solution Approach 1:
The patent modifies the physical and chemical parameters of the base formulation by incorporating specific emollients (dimethicone, cyclomethicone) and waxes (beeswax, carnauba wax) in optimized proportions. This creates a base that can accommodate high powder content (15-40%) while maintaining smooth glide properties through parameter optimization of the formulation system.
Solution Approach 2:
The patent employs a composite material system combining multiple components: silicone emollients for glide, waxes for structure, starches and clays for powder functionality, and binding agents for cohesion. This composite approach allows the formulation to simultaneously achieve high powder content for efficacy and smooth glide for ease of application.
2Object-affected harmful factors
If natural ingredients are used to avoid harmful chemicals, then product safety is improved, but formulation stability and desired properties deteriorate
Solution Approach 1:
The patent uses silicone emollients (dimethicone, cyclomethicone) as intermediary substances that bridge between natural ingredients and performance requirements. These intermediaries provide the necessary glide, stability, and structural properties that pure natural ingredients struggle to deliver, while maintaining overall formulation safety.
Solution Approach 2:
The patent applies different quality standards to different components: natural ingredients (beeswax, carnauba wax, starches) provide safety and biocompatibility, while silicone-based emollients provide consistent glide and stability. This local differentiation of ingredient qualities allows the formulation to achieve both safety and performance.
3Reliability
If aluminum and zinc salts are used to block sweat pores, then antiperspirant efficacy is improved, but health risks increase
Solution Approach 1:
The patent extracts and removes aluminum and zinc salts from the formulation entirely, eliminating the harmful substances while retaining the antiperspirant function through alternative mechanisms using safe, non-metallic ingredients.
Solution Approach 2:
The patent replaces long-standing, effective but harmful aluminum/zinc salt compounds with alternative ingredients that work through different mechanisms. While the alternatives may require higher concentrations or different application frequencies, they provide effective antiperspirant action without the associated health risks.

AI summary
Methods of making a paste deodorant and compositions for the same are described herein. The method includes heating an oil, a butter, and optionally a wax to form a heated mixture; mixing a starch powder into the heated mixture; cooling to a preselected temperature for addition of a temperature sensitive ingredient; adding the temperature sensitive ingredient; and cooling to room temperature with mixing to form a paste deodorant. The paste deodorant includes about 1% wt/wt beeswax to about 12% wt/wt beeswax; about 10% wt/wt or less coconut oil; about 1% wt/wt to about 10% wt/wt of an esterified oil; less than about 16% caprylic/capric triglyceride; at least 20% wt/wt of a starch; and a deodorant agent. The deodorant composition as a whole has at least 95% by weight natural or naturally-derived ingredients.
