Sticks & Hot-Fill Concepts

Hot-fill sticks and balms for sunscreen and spot treatments: a mess-free, on-the-go format filled and finished in-house.

4 Concepts in this format. InSpec can develop a target product profile in this format even if it's not shown here.

How hot-fill sticks are made

Hot-fill formulas are poured molten into the stick or pot and cooled to a consistent set. Done well, the surface stays smooth, with no sink marks or pull-away at the edge. Getting that right takes real process control, and it's a format InSpec runs every week.

Sticks suit targeted, on-the-go use: mineral and tinted SPF sticks for face and spot application, treatment and tinted lip balms, solid moisturizers and cleansing balms, and menthol or camphor analgesic sticks. A stick also fits alongside the rest of a sun-care line, so a continuous-spray SPF, an SPF lotion, and an SPF stick can all come from one manufacturer.

What to settle before you quote

  1. A formula built for the pour

    A stick has to set firm enough to stand in its component and still glide on skin. Bring your formula or start from one of ours. Formulation and filling happen in the same building, so the product stays consistent batch to batch.

  2. Component and size

    Lip balms and face sticks come in standard and custom stick sizes. Choose the component early: packaging minimums can run higher than the production order.

  3. SPF and medicated sticks

    SPF sticks and medicated lip balms are OTC drugs. They need a monograph-compliant formula, SPF testing, and a Drug Facts panel, so build testing time into the launch plan.

  4. Open line time

    Hot-fill runs on a dedicated line with open capacity for new programs. Tell us your target annual volume and we'll confirm timing and minimums.
