Anhydrous Lip Formulation with Composite Gellant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lip-based products often lack substantivity, tend to dry out or clump on the lips, and fail to effectively prevent or treat dry, cracked, or chapped lips while providing inadequate protection against UV radiation.
Innovation Solution
A lip-based product formulation combining Helianthus annuus oil, Carthamus tinctorius oil, and styrene/butadiene copolymer as a gellant, with UV sunscreen agents like octocrylene, avobenzone, and octinoxate, moisturizers such as pentaerythrityl tetra-isostearate, and antioxidants like tocopheryl acetate and tocopherol, to create a substantive, easy-to-apply product that protects lips from UV radiation and moisturizes them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lip-based products are formulated to provide moisturization and UV protection, then they tend to dry out, clump, or crack on the lips, but the present formulation achieves substantivity and smooth application without these defects
Solution Approach 1:
The patent employs a composite gellant system combining Helianthus annuus oil, Carthamus tinctorius oil, and styrene/butadiene copolymer. This composite approach creates a synergistic formulation that provides both substantivity and stability, preventing the product from drying out, clumping, or cracking while maintaining smooth application and prolonged wear.
2Quantity of substance
If lip products contain sufficient moisturizers to treat dry, cracked, or chapped lips, then they become heavy, oily, or tacky, but the present formulation provides effective moisturization with pleasant tactile properties
Solution Approach 1:
The patent utilizes specific concentration ranges of moisturizers (25-35% by weight of the combination of pentaerythrityl tetra-isostearate, cetyl ethylhexanoate, and C12-15 alkyl benzoate) to achieve optimal moisturization while controlling the tactile properties. This parameter optimization ensures effective treatment of dry, cracked, or chapped lips without producing heavy, oily, or tacky sensations.
3Object-affected harmful factors
If lip products include UV sunscreen agents for protection, then they may compromise the tactile properties and spreadability, but the present formulation provides SPF 15-30 protection with easy spreadability
Solution Approach 1:
The patent combines UV sunscreen agents (octocrylene, avobenzone, and octinoxate) with the gellant and moisturizer components into a unified formulation. This merging ensures that UV protection (SPF 15-30) is integrated seamlessly with the spreadability-enhancing properties of the gellant system, allowing easy application without compromising tactile comfort.
4Reliability
If lip products are formulated to be substantive and long-wearing, then they may become difficult to spread or apply, but the present formulation achieves both substantivity and easy application
Solution Approach 1:
The patent optimizes the concentration of the gellant (5-8% by weight of the combination of Helianthus annuus oil, Carthamus tinctorius oil, and styrene/butadiene copolymer) to achieve the right balance between substantivity and spreadability. This parameter control ensures the product remains easy to apply while providing prolonged wear and resistance to transfer.
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 formulation provides effective moisturization, prevents dryness, and offers UV protection with a pleasant tactile experience, maintaining a non-oily, non-greasy feel, and can be used as a base or primer for additional lip products.
