Custom Formulation for Personal Care, Built Around Your Vision

Cerulean Chemistry is a premium product development lab for personal care and topical products. We transform unique ideas into market-ready formulations — and when we're done, the formula is yours, never resold or re-licensed to anyone else.

Formulation Services Tailored to Your Brand

Whether you're launching a new product line or rescuing an existing formula, our cosmetic chemist delivers precision formulation backed by science. If it goes on your body, we can build it.

Custom Formulation Development

From serums and moisturizers to hair care and deodorant, we develop original formulas built to your exact specifications. Every ingredient is selected with purpose — no templates, no shortcuts. And the finished formula belongs to you.

  • Serums, oils & treatments
  • Moisturizers, creams & gels
  • Cleansers, body care & hygiene
  • Hair care & styling products

Stability & PET Testing

Formulas that survive the real world. We run stability studies and preservative efficacy testing (PET) so your product holds its texture, color, and safety from the warehouse to the bathroom shelf.

  • Accelerated stability studies
  • Preservative efficacy testing
  • Freeze/thaw & heat cycling
  • Packaging compatibility

Small Production Runs

Pilot batches and small make-and-fill runs, produced in-house. Launch and validate your product before committing to contract-manufacturer volumes — then transfer the formula you own wherever you like.

  • Pilot & validation batches
  • Small-run make-and-fill
  • Batch documentation
  • CM tech-transfer support

Formula Refinement & Optimization

Already have a formula that needs work? We refine existing formulations for improved texture, stability, efficacy, and shelf life — taking what you have and making it commercially exceptional.

  • Texture & skin feel
  • Stability & shelf life
  • Ingredient cost optimization
  • Performance improvement

Regulatory & Ingredient Guidance

Navigate ingredient safety, labeling requirements, and compliance standards with confidence. We develop your formula to align with FDA and EU cosmetic requirements, so it reaches your manufacturer ready for compliant production.

  • Ingredient safety review
  • INCI labeling compliance
  • Claims guidance
  • Allergen & irritant screening
