Working With a Cosmetic Chemist in Australia: What Custom Formulation Involves, Costs and Takes

You have a product idea. Maybe a face serum with a texture you cannot find anywhere, or a body oil with your own signature scent. A ready-made base will not quite get you there. This is where a cosmetic chemist comes in.

This guide explains what custom cosmetic formulation actually involves in Australia, what it costs, and how long it takes, so you can walk into your first consultation prepared.

Key Takeaways

• A cosmetic chemist turns your brief into a stable, safe and compliant formula you own as your brand’s product.
• At Miakara, product formulation starts from $600 per formula and fragrance formulation from $300 per fragrance (ex GST), each with two rounds of development.
• Manufacturing usually takes 4 to 6 weeks after your sample is approved.
• A clear brief is the single biggest factor in keeping cost and time down.

What Does a Cosmetic Chemist Actually Do?

A cosmetic chemist designs the formula behind a product. That means choosing ingredients, setting their percentages, and making sure the product stays stable, safe and pleasant to use over its shelf life.

A good cosmetic chemist consultant also thinks about the practical side:

• How the formula behaves in your chosen pump, jar or tube
• Which preservative system suits the formula and its packaging
• Whether your ingredient wish list works together
• How claims on your label line up with what the product does

The difference between a home recipe and a commercial product is mostly this work. Texture, scent and colour need to stay consistent from the first batch to the last.

White Label vs Custom Formulation

Not every brand needs a chemist from day one. If a proven base formula suits you, white label products are faster and cheaper to launch.

Custom formulation makes sense when:

• Your product needs a specific active, texture or sensory feel
• You want a formula that competitors cannot buy off the shelf
• You are building a range that needs to feel consistent across products

The Custom Cosmetic Formulation Process, Step by Step

At Miakara, our custom formulation service follows four stages.

1. Share your vision. You complete an enquiry with your product goals, target customer and ingredient preferences. Bring examples of products you love and what you would change about them.
2. Consultation and planning. We book a session to refine the concept, talk through timelines and agree on what success looks like.
3. Development and testing. Our lab creates your product and sends samples for feedback. You test, comment, and we fine-tune before approval.
4. Production and launch. Once you approve, we move to manufacturing in our GMP-certified facility in Epping, Victoria, so you receive market-ready product under your own brand.

What Does Custom Formulation Cost?

Formulation fees vary a lot across Australia, and some labs quote only after a long scoping call. Miakara publishes its pricing:

Beyond the formulation fee, budget for:

• Packaging and labels. Vessel choice can affect the formula, so it is worth deciding early.
• Production run. Your first batch quantity drives your per-unit cost.
• Testing. Stability and preservative testing may be needed depending on the product and where you sell it.
• Extra development rounds. A vague brief often leads to more rounds.

How Long Does It Take?

Development time depends on how complex the product is and how quickly feedback comes back. A simple body oil moves faster than an emulsion with several actives.

Once your sample is approved, manufacturing usually takes 4 to 6 weeks, including production, packaging and quality checks.

To keep things moving:

• Send a written brief with reference products
• Give feedback on samples within a few days
• Lock in packaging before final approval

Australian Rules for Ingredients, Labelling and Claims

In Australia, cosmetics have rules around ingredients, labelling and claims. Ingredient lists must follow the mandatory cosmetic labelling standard, and products making therapeutic claims can fall under the TGA rather than general cosmetic rules.

Your chemist should flag claims that could push your product into a different category. For a deeper look, read what regulatory approvals you need for white label cosmetics and our guide to skincare shelf life and date labelling.

Questions to Ask a Cosmetic Chemist Before You Start

• How many development rounds are included?
• Will you manufacture the product, or only develop the formula?
• What testing do you recommend for this product type?
• Can you help with vessel and packaging choice?
• What happens if I want to scale production later?

At Miakara, formulation and manufacturing sit under one roof, so the formula you approve is the one we produce.

FAQs

Q: How much does it cost to hire a cosmetic chemist in Australia?

Q: Can I adjust an existing formula instead of starting from scratch?

A: Often, yes. If one of Miakara’s ready-made bases is close to what you want, the team can adjust things like fragrance, texture and ingredients. In many cases an existing formula can be adjusted without an extra formulation fee. That is usually faster and cheaper than a brand-new formula.
