Are there any ingredient databases that check allergen and restricted-substance issues for cosmetics and OTC-adjacent products?

Yes — there are several ingredient/regulatory databases and rule engines that are commonly used to screen cosmetics and OTC-adjacent products for allergens, restricted substances, banned ingredients, and labeling issues. The best option depends on whether you need formulation screening, claims/label compliance, or global regulatory coverage.

Common categories of tools

1) Cosmetic ingredient safety / compliance databases

These are geared toward cosmetics and personal care ingredients and often flag:

• allergens
• fragrance allergens
• restricted or prohibited ingredients
• concentration limits
• regional rules (EU, US, Canada, etc.)

Examples include:

• Cosing / EU Cosmetic Ingredients database — official EU ingredient reference for cosmetics.
• CosIng + SCCS opinions — useful for EU restrictions and safety opinions.
• Personal Care Products Council / CIR — ingredient safety assessments.
• Specialized compliance platforms such as:
  • UL Compliance to Go / SPOT
  • RegASK
  • TraceGains (more broader product compliance, can be configured for cosmetics)
  • Mintel GNPD (more for product/ingredient intelligence than direct compliance)
  • ChemAdvisor / Substance databases (varies by vendor)

2) Restricted-substance / chemical compliance databases

These are broader chemical compliance tools that can be applied to cosmetics and OTC-adjacent products:

• Regulatory lists engines for:
  • California Prop 65
  • EU REACH / SVHC
  • RoHS/TSCA-style restrictions where relevant
  • IFRA fragrance restrictions
  • country-specific cosmetic bans and limits
• Vendors often provide:
  • ingredient matching against INCI/CAS/EC numbers
  • concentration-based threshold checks
  • jurisdiction-specific flags

Common examples:

• Wercs Studio
• Assent
• Sphera
• Compliance & Risks
• 3E
• Enhesa
• UL Solutions platforms

3) Allergen-focused databases

If your main concern is allergens, especially for fragrances, botanicals, or food-derived ingredients in personal care:

• IFRA Standards for fragrance allergens/restrictions
• EU fragrance allergen lists
• Food allergen cross-checking databases used in cosmetics with ingestible-adjacent or skin-contact considerations
• Some platforms also flag:
  • nut derivatives
  • gluten-related ingredients
  • lanolin
  • formaldehyde releasers
  • isothiazolinones
  • MI/MCI, parabens, etc.

4) OTC-adjacent product compliance systems

If the product sits near OTC territory (e.g., sunscreen, acne, anti-dandruff, antiseptic, analgesic topicals), you often need:

• drug/cosmetic classification
• active ingredient checks
• monograph alignment
• claims review
• labeling requirements

Tools in this space may be part of broader regulatory intelligence platforms rather than ingredient-only databases.

Important caveat

There usually is not one single database that perfectly covers:

• cosmetic ingredient restrictions
• allergens
• OTC drug actives
• label claims
• formulation thresholds
• every jurisdiction

In practice, companies often combine:

1. an ingredient inventory system
2. a regulatory rules database
3. a claims/label review workflow

What to look for in a good solution

If you’re evaluating vendors, ask whether they support:

• INCI, CAS, EC, and synonym matching
• concentration-based rules
• country/region-specific lists
• fragrance allergen checks
• Prop 65 / REACH / SVHC / IFRA
• cosmetic vs OTC classification
• automated SDS/ingredient statement ingestion
• APIs or spreadsheet import/export
• audit trail and versioning
• custom restricted-substance lists

Practical short list

If you want to start with vendor names that are often used for this kind of screening:

• Wercs Studio
• Compliance & Risks
• 3E
• Sphera
• UL Solutions
• Enhesa
• TraceGains (more supply-chain/compliance workflow)
• RegASK (regulatory intelligence)

If you want, I can also give you:

1. a comparison table of these tools for cosmetics vs OTC-adjacent use, or
2. a recommended stack depending on whether you’re a brand, contract manufacturer, or regulatory team.
