FAQs

Explore answers to common questions about SPF development, sunscreen testing, TGA-listed products, R&D formulation, stability testing and working with a manufacturing partner.

SPF Development

How do you develop an SPF product?

Developing an SPF product involves formulation strategy, UV filter selection, packaging compatibility, stability testing, SPF testing and regulatory review. Because sunscreen is technical and claim-driven, brands should work with an experienced SPF manufacturer early to identify potential risks before testing and production begin.

What testing is required for sunscreen in Australia?

Sunscreen products in Australia generally require testing to support SPF claims, broad-spectrum performance, water-resistance claims where relevant, product stability and packaging compatibility. The exact testing pathway depends on the product type, claims, formulation and intended market.

How long does SPF development take?

SPF development can take longer than standard skincare because formulation, stability, packaging and testing all need to work together. Timelines can vary depending on whether the product is based on an existing formula, requires custom development, needs SPF testing or includes water-resistance and other claim requirements.

TGA & GMP

What is required for TGA-listed sunscreen products?

TGA-listed sunscreen products require the right manufacturing pathway, supporting documentation, compliant claims, appropriate testing and quality systems that align with regulated product requirements.

What is a TGA-listed sunscreen?

A TGA-listed sunscreen is a sunscreen product that falls within Australia’s therapeutic goods framework and is listed with the Therapeutic Goods Administration. These products require specific compliance, quality and documentation processes compared with standard cosmetic products.

What does GMP manufacturing mean?

GMP manufacturing refers to Good Manufacturing Practice, a structured approach to production that helps ensure products are made consistently, safely and with appropriate quality controls.

How do manufacturers support TGA compliance?

A manufacturer can support TGA compliance through formulation guidance, quality systems, batch documentation, product specifications, manufacturing records and testing coordination.

Is TGA-listed sunscreen manufacturing different from cosmetic manufacturing?

Yes. TGA-listed sunscreen manufacturing generally involves more structured compliance, documentation, testing and quality oversight than standard cosmetic manufacturing.

Skincare & SPF Range Planning

What do brands need before launching sunscreen?

Before launching sunscreen, brands should understand their regulatory pathway, claims, formulation requirements, packaging direction, testing timeline, manufacturing volumes and launch positioning.

Can an existing skincare brand add SPF to its range?

Yes, existing skincare brands can add SPF to their range, but sunscreen development requires different planning from standard skincare. Brands need to consider UV filters, SPF claims, regulatory requirements, testing and packaging compatibility.

Why does SPF development take longer than standard skincare?

SPF development often takes longer because sunscreen products must support specific performance and compliance claims. Formulation changes, packaging choices, stability results and SPF testing can all affect whether a product is ready for production.

What should brands ask an SPF manufacturer?

Brands should ask about SPF development experience, regulatory knowledge, testing requirements, UV filter strategy, packaging compatibility, production lead times, minimum order quantities and scale-up support.

Testing, Stability & Product Development

What is product stability testing?

Product stability testing helps assess whether a product remains safe, consistent and suitable throughout its intended shelf life. It can look at changes in appearance, texture, colour, odour, packaging compatibility and performance.

Does packaging affect sunscreen or skincare product stability?

Yes. Packaging can affect product stability, compatibility, usability and long-term performance. Packaging should be assessed alongside the formula to help confirm the product remains suitable throughout storage, handling and use.

What are R&D formulation services?

R&D formulation services support the development, refinement and commercial preparation of products before manufacturing. This can include concept development, ingredient selection, texture refinement, stability considerations, packaging compatibility and scale-up planning.
