I’m ready to move five products from concept to lab-ready formulas and need an experienced cosmetic formulator who can take the ideas below and turn them into stable, scalable recipes. Scope of work Skincare and sunscreen: develop lotion and cream bases that deliver deep hydration, visible repair, and broad-spectrum UV protection. Haircare: create a rich rinse-off conditioner that shields strands from salt, cold, wind, and chlorine while restoring softness. All formulas must be skin- and scalp-safe, cosmetically elegant, and compliant with relevant EU / FDA regulations. Key considerations • Each product should rely on proven actives and photostable filters, avoiding reef-harming or heavily restricted ingredients. • Texture, absorbency, and sensory profile matter as much as efficacy; the finished products should feel lightweight, non-greasy, and leave no white cast on any skin tone. • I will need ingredient percentages, detailed phase instructions, recommended processing temperatures, and suggested preservative systems. • Please outline any specialised equipment needed for pilot batches so I can prepare the lab accordingly. Deliverables 1. Fully written formula for 5 products (surf zinc, SPF sunscreen/moisturiser, pre exposure haircare, post exposure haircare, and post exposure skincare (INCI, % w/w). 2. Step-by-step manufacturing procedure for each product. 3. Stability and compatibility test plan with pass/fail criteria for each product. 4. Brief supplier list for hero ingredients with MOQ guidance for each product. 5. One round of tweaks after the first bench sample, if required for each product. If you’ve taken multifunctional skincare, reef-safe sunscreen, or sport-proof conditioners from bench to shelf before, your expertise will be invaluable here.

Hello, Your project is exactly the kind of work I enjoy: bridging innovative concepts and market-ready formulations. I’m a PhD chemist and biochemist with over 9 years of experience in formulation and applied research, currently working as CSO of a biotech company. Alongside my research background, I also run a regulatory consulting practice (EU/UK/US), which allows me to design formulations that are not only effective but fully aligned with cosmetic regulations from the start. Anyway, I would like to discuss in depth the details of your project. Please, feel-free to contact me pia DM for this. Looking forward from hearing from you! J. Royes

As a chemical engineer, I have the necessary knowledge and experience to take your skincare, sunscreen, and haircare products from concept to formulation. My understanding of the intricacies of different compounds, their behavior in various environments, and their potential reactions is crucial for creating stable, effective, and safe formulas - a key requirement for your project. Moreover, I understand the significance of high-quality ingredients that are compliant with EU/FDA regulations. With my expertise, you can be assured that each product will rely on proven actives and photostable filters that align with today's cosmetic standards while avoiding any reef-harming or restricted components. Additionally, I'm adept at providing comprehensive phase instructions, identifying recommended temperatures for processing, outlining suitable preservative systems, and highlighting any specialized equipment needed for pilot batches in order to ensure your lab is properly equipped. With me, you get not just formulas but also a detailed manufacturing procedure and a robust stability and compatibility testing plan that complies with your specific parameters. Let me bring my scientific proficiency to the table for your project’s success!

I have formulated high-SPF sunscreens and active-led skincare that meet strict stability and international regulatory standards. For these five products, I will leverage my experience in balancing botanical efficacy with pharmaceutical stability to ensure your concepts translate into high-performance, lab-ready solutions optimized for scale-up. Whether you are targeting clean-beauty standards or clinical benchmarks, I understand how to navigate the complex interplay of emulsification and preservative systems to protect your brand's integrity. To move your concepts to the lab, I will develop Qualitative and Quantitative (Q&Q) formula sheets, ensuring ingredient synergy and compliance with INCI labeling requirements. For the sunscreen, I will focus on optimizing UV filter dispersion—selecting mineral or chemical filters—to achieve your target SPF/PA rating while maintaining a superior sensory profile. For the hair and skincare lines, I will implement cold-process or high-shear emulsification methods, providing compounding instructions, raw material sourcing lists with CAS numbers, and stability testing protocols to ensure a seamless transition to a contract manufacturer. Do you have a specific "free-from" list or are you seeking COSMOS/Ecocert certification for these formulations? I'd also love to know if you have a preferred rheology for the hair care line—such as a specific viscosity—so I can select the appropriate conditioning agents. I am available for a brief chat or call to discuss the textures and performance benchmarks you have in mind for each of these five products.

Hi Brett B., Just last week I completed a similar task successfully, so I can get started on this without any ramp-up time. Two questions: What markets will these launch in (US, EU, or global), and what exact claims are required for the sunscreens (SPF target, UVA-PF/critical wavelength, water-resistance minutes)? Any constraints on silicones, fragrance/allergens, animal-derived content, and use of tint/iron oxides to eliminate white cast across all skin tones? Two suggestions: Build a shared emulsion platform for lotion/cream/SPF (common oil phase, emulsifier, rheology) to streamline scale-up and sensory consistency; pair SPF and surf zinc with coated non‑nano ZnO (optionally TiO2), optimized dispersions, and polymeric film formers for 80‑min water resistance and low cast. Use an in‑vitro screening funnel (in‑vitro SPF, ISO 24443 UVA/CW) plus early stress tests (centrifuge, heat/cold, pH, hard water/chlorine/salt) to converge fast before full stability. Action Plan: - Phase 1: Requirements lock (markets/claims, banned lists, sensory, actives). - Phase 2: Base design + draft formulas (INCI, % w/w, phases, temps, preservative), pilot gear list (heated vessel with sweep, rotor–stator 10–20k rpm, vacuum, precise scales, pH meter, viscometer). - Phase 3: Bench builds A/B, in‑vitro SPF/UVA, rheology/sensory tuning. - Phase 4: Stability/compatibility (4/25/40/45°C, F/T, centrifuge, chlorine/salt exposure; packaging) Best Regards, Sid

Dear Sir/Madam I am a chemist from Zimbabwe and holds B.Sc. Chemistry and Biochemistry from the University of Zimbabwe as well as M.Sc. Chemistry from the University of Siegen in Germany. I have experience in the manufacture of personal care products. Creams as emulsions offer the best physical requirements for skin care products to achieve the effects on and in the skin. They supply the skin with lipophilic and hydrophilic active substances in larger quantities. Out of the applied cream, water evaporates slowly from the skin, leaving a thin film with the non diffusable substances and reinforcing the hydro-lipid film. The substances smoothens the skin and provide protection against microorganisms with the acid mantle and a suitable, partially water-soluble preservative. Lipids, vitamins, and moisturizing substances as well as preservatives and emulsifiers/thickeners are part of the fixed recipe. Useful addition of alcohol supports the dissolution of sorbic acid, causes a cooling effect on the skin, and acts as an enhancer. Lactic acid maintains the acidic nature of the skin and is an emollient, exfoliator and humectant, that is it moisturises the skin. Complexing/chelating agents include sodium Anti-oxidants include Tocopherol (vitamin E), Ascorbic acid (vitamin C) and cysteine. Citric acid and lactic acid are for pH control. Solvents such as ethanol and glycols can be used. Yours faithfully Brian Chiunye
