Maker ingredient guide
Room spray base
Pre-built spray starting point
Typical lab category: Room Spray Base
A room spray base is a supplier formulation meant to hold fragrance in a sprayable matrix. Solubilizer need, alcohol content, and flammability vary — treat every base as its own SDS project.
Supplier blend — may include water, alcohol, solubilizers, and preservatives.
Practical maker contexts — not maximum use rates.
- Room sprays and linen sprays when the supplier confirms textile compatibility
- Air-care prototypes before moving to fully custom solvent systems
Suggested pairings for learning—not a formula recipe. Always confirm compatibility with your suppliers.
Beginner glossary — formulation terms
Plain-language definitions. Role labels above link here when a match exists.
What is surfactant?
A surface-active ingredient that helps water interact with oils, dirt, or air — often responsible for cleansing, foaming, or spreading in soaps and detergents.
What is humectant?
An ingredient that attracts and holds moisture; often used so sprays, lotions, or bath products feel less drying on skin or hair.
What is emulsifier?
Helps oil and water stay blended instead of separating — important in lotions, conditioners, and some sprays.
What is solvent?
Something that dissolves or carries other materials (oils, resins, actives). Water, glycols, and alcohol are common solvents in maker formulations.
What is carrier oil?
A plant (or sometimes mineral) oil used to dilute essential oils or fragrance before skin application, or as a base in balms and anhydrous blends.
What is chelating agent?
Binds metal ions in water that can otherwise affect color, odor, or stability; often used alongside pH control or preservation strategies in soaps and cleaners.
What is ph adjuster?
Raises or lowers acidity/alkalinity. Many products perform best in a target pH range; adjusters help you move toward that range carefully.
What is thickener?
Increases viscosity so liquids feel richer or cling better — common in gels, shower products, and some concentrates.
What is preservative?
Helps limit microbial growth in water-containing products. Choice and use depend on formula, pH, and supplier guidance.
What is wax?
A solid, meltable material that provides structure — the backbone of candles and many balms; also used to thicken anhydrous blends.
What is stabilizer?
Helps keep a formula uniform over time (texture, suspension, or emulsion stability) — different from a preservative, which targets microbes.
What is emollient?
Softens and smooths skin feel — many oils and esters act as emollients in balms, lotions (oil phase), and hair oils.
What is rheology modifier?
Changes how a liquid flows or suspends particles — clays and some polymers are common examples in masks and anhydrous sticks.
