Job description

Based in the Los Angeles/Carson corporate headquarters, Dermalogica is seeking an Associate Chemist to support R&D formulation development. This hands-on laboratory role supports Formulating Chemists and Senior Chemists by preparing bench batches, executing experiments with scientific discipline, documenting results, and supporting samples for development, stability, compatibility, and cross-functional needs.

Essential Duties and Responsibilities:

1. Bench Formulation and Sample Preparation

  • Prepare lab-scale batches under direction, including weighing raw materials, mixing, heating/cooling, pH adjustment, homogenization, filling, and sample labeling.
  • Support prototypes, formula iterations, marketing submissions, benchmark comparisons, panel samples, stability/compatibility fills, clinical/education samples, and other R&D sample requests.
  • Maintain accurate lab notes, batch records, sample labels, retains, and sample inventory with strong attention to detail.

2. Experimental Execution and Formulation Support

  • Execute designed experiments, raw material screens, reformulation support batches, and prototype adjustments according to direction from the project owner.
  • Record key observations and data such as appearance, odor, color, texture, pH, viscosity, weight, temperature, mixing speed, processing time, and equipment used.
  • Compare samples against controls, benchmarks, and prior versions; communicate observations clearly and escalate unusual results or processing concerns promptly.
  • Assist with support batches and documentation for stability, package compatibility, preservative efficacy testing, safety/clinical testing, formula quotes, and regulatory review packages.

3. Laboratory Operations, Safety, and Good Documentation

  • Work comfortably in the lab and perform the practical hands-on aspects of bench formulation, including standing at the bench, handling lab-scale containers, operating routine equipment with training, and cleaning/organizing work areas.
  • Follow laboratory safety procedures, PPE requirements, chemical hygiene practices, SOPs, and GLP/GMP-aware documentation expectations when handling cosmetic raw materials, fragrances, essential oils, and lab chemicals.
  • Use routine lab equipment such as balances, pH meters, viscometers, hot plates, overhead mixers, homogenizers, water baths, and filling tools with proper training and care.
  • Update project/sample tracking systems such as Coptis/Ithos, Wrike, or other R&D systems as needed, while protecting confidential formula, supplier, and project information.

Qualifications:

  • Bachelor's degree (BS) in Chemistry, Cosmetic Science, Biology, Pharmaceutical Science, Chemical Engineering, or a related scientific field.
  • 0 to 3 years of relevant laboratory or formulation experience; internship, co-op, academic lab, cosmetic/personal care, pharmaceutical, food, or related product development experience will be considered.
  • Comfortable spending adequate time in a laboratory environment performing practical bench work with accuracy, patience, and scientific discipline, including standing, handling lab-scale containers, and using standard laboratory equipment with or without reasonable accommodation.
  • Strong attention to detail, accurate documentation habits, and ability to follow written procedures and verbal instructions.
  • Basic understanding of laboratory safety, PPE, chemical handling, GLP/GMP principles, and good documentation practices.
  • Excellent written and verbal communication skills with the ability to collaborate in a team-oriented, fast-paced R&D environment.
  • Proficiency with Microsoft Office is a must. Familiarity with formulation systems, project management tools, or laboratory data systems is a plus.

Preferred Experience:

  • Prior experience in cosmetics, personal care, pharmaceutical, food, or related formulation laboratory work is preferred.
  • Exposure to emulsions, surfactant systems, gels, serums, sunscreen/SPF systems, stability testing, or package compatibility testing.
  • Experience using pH meters, viscometers, balances, overhead mixers, homogenizers, hot plates, or similar lab equipment.
  • Basic ability to organize data, summarize observations, and communicate experimental results clearly.
