I'm looking for an expert in oral care formulation to help create a specialized mouthwash. My goal is to develop a product tailored with specific benefits, including being gentle on sensitive teeth, delivering quick whitening results, and ensuring long-lasting effects. I'm also aiming for a peroxide-free formula. While I have some ideas for the active ingredients, I will need your guidance and expertise to finalize them. Approval from laboratories in both Pakistan and Dubai is essential. If you've got experience in crafting innovative oral care solutions and navigating regional compliance, I'd love to collaborate with you!

I need an experienced tutor who knows the Alberta Chemistry 30 curriculum inside-out and can meet my student online every week. Sessions will be live, interactive, and focused on the exact unit they’re working through—whether that ends up being thermochemistry, organic reactions, equilibrium, or something entirely different in the course outline. We will meet once a week on Zoom, Google Meet, or a comparable platform that lets you screen-share and use an on-screen whiteboard. Each lesson should combine clear concept explanations with problem-solving practice, then wrap up with a quick plan of what we’ll tackle next time so progress stays visible. You’ll fit well if you have prior Chemistry 30 teaching or tutoring experience, communicate in plain language, and can ...

I already work at an advanced level with kinetic theory, yet I want to sharpen my non-isothermal modeling skills for biomass gasification and pyrolysis. The goal is to walk through rigorous, step-by-step workflows—from selecting the appropriate kinetic scheme and choosing heating rate protocols, through parameter estimation and model validation—so that I can streamline my own research code and confidently defend the methodology in publications. Here’s how I picture the engagement: • A short series of live, screen-shared sessions (recordings provided) where you demonstrate your preferred workflow. I’m comfortable talking equations, differential mass balances, and Arrhenius-type parameter fitting right away, so please pitch the discussion accordingly. •...

This project calls for a skilled welder who can recommend the best process—MIG, TIG, or Arc—once the specific joint design and material are confirmed. I’m still finalising whether the work will involve steel, aluminium, or stainless, and whether the end-goal is a repair, a fresh fabrication, or something decorative, so your guidance on technique, filler metals, and required prep will be valuable. You’ll need to supply your own equipment, demonstrate consistent bead quality, and meet standard safety practices. Clear photos or short clips showing set-up, test passes, and finished welds will serve as acceptance criteria. Please outline the process you would follow, the codes or standards you normally work to, and typical turnaround times.

I’m ready to take a new skincare cream/lotion from concept to the lab bench and I need an experienced cosmetics formulator to make it happen. The sole purpose of this product is to reinforce the skin’s natural barrier—think protection against transepidermal water loss, everyday pollutants, and irritation triggers—so every ingredient choice, processing step, and stability target must keep that goal front-of-mind. Here’s what I’ll need from you: • A complete, bench-ready formulation (INCI list with exact percentages) that delivers measurable barrier support. • Guidance on hero actives, emulsifiers, humectants, and occlusives that align with current EU/FDA cosmetic regulations and clean-beauty sensibilities. • A concise manufacturing p...

I'm looking for a developer that preferably has experience with fragrance to create a unique similar to common car vent clip product. This will be similar to existing car scent products but with a new method that I can explain further in discussions. Requirements: - Develop a long-lasting, appealing car-like scent Diffusor - Formulate vent clip delivery system - Provide samples for testing and approval by printing Ideal Skills & Experience: - Expertise in fragrance formulation - Experience with automotive air freshener products - Knowledge of safety regulations in fragrance production

I need a Pakistan-based chemical engineer who can jump straight into Aspen HYSYS and build a reliable simulation model for an ongoing process-engineering and product-development study. The work centres on a biochemical route, so experience that spans classical process design as well as biochemical engineering quirks will be valuable. Here’s what I expect: • A clean, well-structured HYSYS file (.hsc) with all units, streams, and thermodynamic packages properly defined. • Stream and equipment sizing reports that can be lifted directly into the wider project documentation. • A brief technical note (2–3 pages) that explains key assumptions, convergence strategy, and any sensitivity checks carried out. Accuracy, clear documentation, and adherence to good simul...

I need a chemist or a tech in chemistry to produce chemical reagents specifically for testing chlorine content in water, following formulations and procedures that are already in place. Key Requirements: - Ability to scale production to meet demand - Adherence to safety and quality standards Ideal Skills and Experience: - Background in chemistry or chemical engineering - Experience in producing water testing reagents - Knowledge of regulatory requirements for chemical products Please provide a timeline and cost estimate. company os located in Denver Colorado USA and all the materials and equipments are located on site.

I need a partner who can run a quota-balanced survey of 1,000 Indian consumers so I can see whether people treat dietary supplements as general health aids or as medicines meant for curing illness. The objective is purely to understand broad public perception, not to push any specific brand. Sampling plan • Age quotas: 18-25, 26-40, and 41+ in roughly equal proportions, with gender and SEC spread matched to census benchmarks. • Geographic reach: respondents drawn across Tier 1, Tier 2, and Tier 3 cities for a nationally representative snapshot. Questionnaire I will supply draft, neutral items such as “What are supplements mainly for?” and “Do you consider supplements closer to medicines or foods?” Your first task is to sense-check wording and trans...
