Ingredient review
Benzylidenecamphor Hydrolyzed Collagen Sulfonamide
INCI: Benzylidenecamphor Hydrolyzed Collagen Sulfonamide
An experimental UV-filter ingredient that may offer sun protection and skin conditioning, but it is rarely used in mainstream products and has limited safety data.
In plain English
This ingredient is a lab-made molecule that combines a UV-absorbing compound (benzylidenecamphor) with a protein fragment (hydrolyzed collagen) and a sulfonamide group. The idea is that it can both block UV rays and help moisturize or firm the skin. However, it is not a common ingredient in store-bought sunscreens, and there is very little published research on how well it works or how safe it is for everyday use.
Quick decision guide
Read the cautions before using
Benzylidenecamphor Hydrolyzed Collagen Sulfonamide can be useful, but watch for some irritation potential.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Benzylidenecamphor Hydrolyzed Collagen Sulfonamide.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic compound where a camphor derivative (known for UV absorption) is chemically linked to hydrolyzed collagen (a protein fragment) and a sulfonamide group. It is designed to function as a UV filter while also providing some skin-conditioning benefits.
How it works
The benzylidenecamphor part absorbs ultraviolet (UV) light, converting it into heat and preventing it from damaging skin cells. The hydrolyzed collagen portion may form a thin film on the skin, potentially helping to retain moisture or temporarily smooth the skin's surface. The sulfonamide group may enhance the molecule's stability or solubility in formulations.
Pros
Dual function
Combines UV absorption with a collagen-derived conditioning agent, potentially offering both sun protection and skin smoothing in one ingredient.
Novel approach
Represents an innovative attempt to create multifunctional sunscreen ingredients, which could simplify formulations.
Cons and cautions
Limited research
There is very little published scientific evidence on its safety, efficacy, or long-term effects, making it a risky choice for consumers who prioritize proven ingredients.
Regulatory uncertainty
This ingredient is not approved as a UV filter in major markets like the US or EU, so it may only appear in niche or unregulated products.
Best for
- People interested in experimental or novel sunscreen technologies
- Those looking for a combined UV filter and skin-conditioning ingredient in a single molecule
Use caution if
- Individuals with known sulfonamide (sulfa) allergies should exercise caution and consult a dermatologist before using products containing this ingredient
Usage tips
Safety summary
Safety data for Benzylidenecamphor Hydrolyzed Collagen Sulfonamide is extremely limited. The sulfonamide group raises a theoretical concern for individuals with sulfa allergies, though topical exposure is generally considered low risk. Without robust toxicological studies, its safety profile remains unclear.
Research notes
No peer-reviewed studies specifically on this ingredient were found. Related research on benzylidenecamphor derivatives indicates UV absorption capability, but the addition of hydrolyzed collagen and sulfonamide is novel and unstudied.
Common label clues
- Typical concentration
- Typically used at 1–5% in sunscreen formulations
- Regulatory status
- Not approved as a UV filter by the US FDA or the EU Cosmetics Regulation. It may appear in products outside these jurisdictions, but its status is uncertain.
- Common uses
- Sunscreens, Daily moisturizers with SPF, Anti-aging sun protection products
- Environmental note
- Camphor derivatives have been studied for potential environmental persistence and toxicity to aquatic life, but specific data for this compound is unavailable.
Good to know
- Benzylidenecamphor derivatives are more common in European sunscreens, but this specific hybrid with collagen and sulfonamide is extremely rare.
- Hydrolyzed collagen in this context is unlikely to provide significant anti-aging benefits because it is chemically modified and present in low concentrations.
