Cellulose-Derived Sunscreen Capsules for Even Rinse-Resistant Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunscreen products often fail to provide consistent and even protection against UV radiation, especially after rinsing, and have an unpleasant feel on the skin.
Innovation Solution
A sunscreen composition encapsulating active agents in cellulose-derived capsules, combined with body washes, shampoos, and other hygiene products, provides enhanced SPF and even distribution, maintaining protection even after rinsing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sunscreen products are applied regularly, then UV protection is provided, but the protection is inconsistent and uneven, especially after rinsing
Solution Approach 1:
The patent incorporates sunscreen active agents into body wash, shampoo, and other hygiene products that are applied before sun exposure. This preliminary application ensures sunscreen is deposited on the skin during routine hygiene activities, providing consistent protection before UV exposure occurs.
Solution Approach 2:
The patent uses hygiene products (body wash, shampoo, conditioner, lotion, mousse, spray, gel, hand sanitizer) as intermediaries to deliver sunscreen active agents to the skin. These intermediaries facilitate even distribution and adherence of sunscreen during normal hygiene routines, improving consistency and duration of protection.
2Ease of operation
If sunscreen products are formulated for regular use, then convenience is improved, but the products do not provide adequate protection due to loss of coverage from swimming, exercise, and dermal penetration
Solution Approach 1:
The patent combines sunscreen functionality with multiple hygiene product types (body wash, shampoo, conditioner, lotion, mousse, spray, gel, hand sanitizer). This multi-functionality allows a single product line to serve both hygiene and sunscreen purposes, maintaining convenience while ensuring adequate protection through various application opportunities throughout the day.
Solution Approach 2:
The patent enables continuous sunscreen protection by incorporating active agents into hygiene products used throughout the day. Each hygiene application replenishes and maintains sunscreen coverage, ensuring continuous protection against UV radiation, swimming, exercise, and dermal penetration losses.
3Reliability
If sunscreen products are applied frequently, then UV protection is maintained, but the products have an unpleasant oily feel on the skin
Solution Approach 1:
The patent modifies the physical and chemical parameters of sunscreen formulations to reduce oily feel while maintaining protection. This includes adjusting viscosity, spreadability, and drying characteristics of the hygiene products containing sunscreen active agents, making them more acceptable for frequent application.
Solution Approach 2:
The patent uses composite formulations combining sunscreen active agents with hygiene product bases that provide desirable sensory properties. The composite materials maintain UV protection efficacy while improving skin feel and reducing unpleasant oily sensations through careful formulation of the vehicle components.
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 composition offers high SPF protection that lasts longer and feels gentle on the skin, ensuring effective UV protection throughout daily hygiene routines.
Implementation Method 1
utilizing encapsulation technologies, milder surfactant systems, and good adhesive polymers that provide a strong binding capability, making it more efficient for deposition of sunscreen
Implementation Method 2
a sunscreen active agent included in a sunscreen composition absorbs or blocks UV radiation from about 290 to about 420 nm
Implementation Method 3
good adhesive polymers that provide a strong binding capability, making it more efficient for deposition of sunscreen

AI summary
A sunscreen composition comprised of one or more sunscreen active agents encapsulated in a cellulose derived capsule wherein the composition can contain one or more additional agents. A sunscreen composition can be mixed with a bodywash, shampoo, conditioner, lotion, gel, soap, cream, hand sanitizer, spray or mousse and can be used by an individual during their normal hygiene processes, such as during a shower or bath or while applying a body product to their skin or hair.
