## 1. Executive Summary & Core Engineering Scope
How a roll-on ball, a twist-up propel-repel elevator and a fine-mist sprayer actually work; which suits a baking-soda, magnesium, oil-based or alcohol natural deodorant; and the indicative MOQ and factory-gate lead time for each route from China.

A natural deodorant brand picks a format for reasons of ritual and plastic — and then discovers the format has a mechanism, the mechanism has tolerances, and the formula decides which mechanism survives. This guide explains the three mechanisms in engineering terms, matches them to the common natural formula types, and gives the minimum and days for each.

Roll-on : a 19–35 mm PP, PE or stainless-steel ball in a snap-fit housing on a 30–100 ml bottle, sealed at rest by a soft seat ring in the cap — for liquid and gel natural formulas; from ~500 pieces, 7–25 days . Twist-up stick : a propel-repel spiral elevator driving a carrier cup, 50–75 g — for solid baking-soda, magnesium and wax formulas; low thousands stock, 5,000–10,000 moulded-in colour, 15–25 days . Spray : a stock 12.5–24 mm fine-mist sprayer at 0.1–0.2 ml per shot on glass, PETG or aluminium — for alcohol-based formulas, which rule out PET above ~30% ethanol; ~2,000 printed, 7–25 days plus sprayer in parallel . Sprayed colour on any of them is 2,000–5,000 per shape and 30–40 days.

A roll-on is the simplest of the three. A ball of 19–35 mm sits mostly inside a snap-fit PE, PP or PC socket and turns freely; product wets the exposed surface as it rolls. Two tolerances are the whole product: too loose leaks in a bag, too tight will not roll — and a socket that rolls on water can seize on a 2,000–50,000 mPa·s gel. At rest the seal is not the ball; it is a soft seat ring inside the screw cap that presses the ball down onto the socket , which is what stops an alcohol or perfume roll-on evaporating on shelf. Ball, housing and neck are one system and are specified together, never separately.

A stick uses a propel-repel spiral elevator : turning the base rotates a threaded spiral (metal or plastic) that drives a carrier cup up to present the solid and back down to retract it. The spiral tolerance is the whole product — a cheap elevator wobbles, advances unevenly, and fails the 76 cm drop test and the customer. The formula matters twice. A natural solid built on baking soda, magnesium, arrowroot and waxes softens with heat — a 45°C lorry in summer will deform a poorly formulated stick , so the filled pack is held at 48°C for 24–48 h. And baking-soda formulas are alkaline while oil-rich formulas extract plasticisers, so the barrel and cup are PP and the exact formula sits in the exact stick at 48°C for 30 days before production. Plated collars stay exterior-only, with no nickel on skin-contact surfaces.

A deodorant spray is a stock fine-mist sprayer of 12.5–24 mm — pump size chosen to the bottle neck, never the reverse — delivering 0.1–0.2 ml per actuation with a SUS304 spring, on a glass, PET, PETG or aluminium bottle with a screw or crimp collar and overcap. Natural sprays are usually alcohol-based, and that decides the bottle: PET fails above ~30% ethanol , swelling and hazing, so the choice is glass, alcohol-rated PETG or aluminium. Because a sprayer has many small parts and its own tooling is costly, nobody tools a custom sprayer for a launch; the sprayer is stock and the minimum belongs to the bottle print. A sprayer tested on water can stream instead of misting on the real formula, so dose and mist pattern are verified on the actual bulk: 0.1–0.2 ml per shot within 0.02 g, even mist, ≥1,500 actuations , collar torque 58.8–224 N by diameter, and the overcap flip-tested without cracking.
