Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing sunscreen compositions with Pongamia pinnata Seed Extract face challenges such as unfavorable sensory properties and high use levels, complexity, and cost, particularly when used with mineral sunscreen actives, while organic sunscreen actives lack substantial photoprotection in the UVA-1 region.

Innovation Solution

A synergistic combination of Pongamia pinnata Seed Extract with organic sunscreen actives like salicylates, such as homosalate and octisalate, enhances UVA-1 photoprotection without detracting from UVA protection, allowing for reduced use of organic actives and eliminating the need for additional auxiliary ingredients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Pongamia pinnata Seed Extract is used with mineral sunscreen actives to enhance photoprotection, then UVA and UVB protection is improved, but sensory properties become unfavorable and formulation complexity increases

Engineering Contradiction:

Improvephotoprotection capabilityVSAvoidsensory properties

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the parameter of sunscreen active type from mineral to organic (specifically salicylates like homosalate and octisalate), which fundamentally alters the formulation characteristics. This parameter change allows the Pongamia pinnata Seed Extract to provide enhanced UVA-1 photoprotection without the sensory drawbacks associated with mineral sunscreen actives, while maintaining overall photoprotection efficacy.

Inventive Principle:

2Reliability

If Pongamia pinnata Seed Extract is used to boost photoprotection, then UVA protection is enhanced, but use levels become relatively high and cost increases

Engineering Contradiction:

Improvephotoprotection capabilityVSAvoiduse level of Pongamia pinnata Seed Extract

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges Pongamia pinnata Seed Extract with organic sunscreen actives (specifically salicylates) to create a synergistic combination. This merging allows the extract to work more efficiently at lower concentrations, enhancing UVA-1 photoprotection without requiring high use levels. The combination of multiple photoprotective agents creates a complementary effect that reduces the overall quantity of Pongamia pinnata Seed Extract needed.

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If organic sunscreen actives are used, then formulation is simpler, but photoprotection in the UVA-1 region is insufficient

Engineering Contradiction:

Improveformulation complexityVSAvoidUVA-1 photoprotection

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent creates a composite photoprotection system by combining Pongamia pinnata Seed Extract with organic sunscreen actives (salicylates). This composite approach allows the formulation to maintain simplicity while achieving enhanced UVA-1 photoprotection. The extract acts as a complementary photoprotective agent that fills the UVA-1 protection gap of conventional organic sunscreen actives, creating a more comprehensive sun protection profile without significantly increasing formulation complexity.

AI summary

A sunscreen composition including at least one organic sunscreen active and Pongamia pinnata Seed Extract. The at least one organic sunscreen active may be selected from at least one organic sunscreen active having no substantial photoprotection capabilities within the UVA-1 region. The at least one organic sunscreen active may be selected from a salicylate. For example, a salicylate may be present in an amount from about 3.0 wt. % to about 20.0 wt. % and the Pongamia pinnata Seed Extract may be present in an amount from 0.26 wt. % to 4.9 wt. %, based on the total weight of the sunscreen composition. Thus, for example, the weight ratio of homosalate to the Pongamia pinnata Seed Extract may be from about 9:1 to about 18:1 and the weight ratio of octisalate to the Pongamia pinnata Seed Extract may be from about 4.0:1 to about 9:1.
