For long-lasting scent in personal care, fabric & cleaning
Fragrance Encapsulation
Advanced microencapsulation technology in slurry or dry powder formats — for products that need scent to last days or weeks, not hours.
Every project starts with a consultation. We believe in personal service and expert execution. A consultation gives us the time to understand your project, confirm it's the right fit, and agree on the best path forward together. If we move forward, your consultation is credited toward the project.
What is fragrance encapsulation?
Microencapsulation creates a protective barrier around fragrance oils, forming tiny capsules that preserve scent integrity until the moment of release. These capsules can be engineered to respond to moisture, friction, pH, or temperature — ensuring the fragrance performs exactly when and where it's intended.
We work with a specialized manufacturing partner who performs microencapsulation exclusively for our fragrance oils and formulas. We do not encapsulate third-party fragrances. Our encapsulated scents are designed to be long-lasting, touch-release, and stable across aqueous and dry formats.
How it performs
Three technical properties that change what a fragrance can do inside a finished product.
Enhanced longevity
Fragrance molecules are protected from evaporation and degradation, making scents last significantly longer. Microencapsulated scents release gradually when the capsule shell is broken through rubbing, warmth, or moisture exposure.
Controlled release
Time-release effect delivers consistent scent throughout the day — perfect for products requiring extended customer experience.
Fragrance stability
Protection from heat, air, light, and other environmental factors ensures fragrance remains fresh and effective over time.
Applications
Where encapsulated fragrance changes the product experience.
Personal care
Body lotions, shampoos, conditioners, and skincare with long-lasting fragrance that releases through skin contact and warmth.
Home cleaning
Surface cleaners, floor care, and air fresheners with sustained scent release over time, not just a moment of fragrance at use.
Fabric care
Laundry detergents, fabric softeners, and dryer sheets that keep clothes fresh for days through friction-triggered release.
Cosmetic products
Perfumes, body sprays, and beauty products with enhanced scent performance and extended dry-down.
Frequently asked questions
What is fragrance microencapsulation?
Fragrance microencapsulation is a process where fragrance molecules are enclosed in tiny capsules. These capsules protect the fragrance and release it gradually over time when triggered by friction, heat, or moisture. We offer both biodegradable and conventional capsule formats.
Should I use slurry or dry powder format?
It depends on the product form. Powder can be used for any dry product (detergents, cleaners, dry shampoo, etc.), while slurry is usually used for liquid applications. For any of our specialty services, a consultation is the first step — that's where we determine the right format and blend for your desired performance and application.
What are the production minimums and lead times for encapsulation?
Minimums vary by type of capsule and start at 100 lbs of encapsulated product. Once the fragrance oil is on hand, lead times are 4–6 weeks for encapsulation.
Does encapsulation change how the fragrance smells?
No — encapsulation impacts how the fragrance is delivered, not its character. The capsules protect the fragrance molecules until they are released (by friction, water, pH, etc.). Encapsulation only affects performance — bloom and longevity — not how the fragrance smells.
Do an oil's certifications carry over to its encapsulated version?
No — all certifications have to be re-checked for the encapsulated version. The certifications shown on our product pages apply to the oil only.
Can you encapsulate my existing fragrance formula?
No — we don't work with anyone else's formulas for anything we do. We only encapsulate Stock Fragrance's proprietary fragrance oils, which is how we guarantee quality and performance.
Is microencapsulation safe and eco-friendly?
Safety and environmental profile depend on the capsule format. We offer both biodegradable capsules — which break down naturally — and conventional formats, and capsule chemistry is one of the things we determine in your consultation based on your product and market. Encapsulated fragrance is used across personal care, home care, and cosmetic products; compliance for your specific application is verified per project.
What products can benefit from microencapsulation?
Microencapsulation is ideal for laundry detergents, fabric softeners, body lotions, shampoos, surface cleaners, air fresheners, and any product where long-lasting fragrance is desired.
