Agnes Kielb

I am a personal care formulation chemist with extensive experience developing skin care, hair care and color cosmetics products for brands and private label customers. I work independently in R&D and oversee pilot and production batches, optimizing processes to ensure reproducible, high-quality products.

At June Jacobs Labs I led new product development, coordinated with QC and compliance, and managed OTC and SPF projects including external testing and global regulatory considerations. I seek and evaluate new raw materials and technologies to keep product lines aligned with market trends.

Previously I formulated color cosmetics, handled shade matching and pigment testing, and prepared technical reports and customer-facing documentation. I provided technical support to marketing and sales teams and trained new staff on formulation and lab procedures.

I combine strong lab skills—pH and viscosity measurement, sterile technique, scale calibration, microscopy—with proficiency in Microsoft Office, effective cross-functional communication, and a proven track record of managing projects from concept to delivery.
