Inspired by the global "Beauty Sleep" trend, Devan introduces its latest innovation in sleep wellness. The active ingredient is derived from an upcycled by-product of Australian Tea Tree oil. This active ingredient acts by two complementary pathways, inhalation and skin contact, to improve nighttime benefits and skin regeneration to provide a healthier looking skin and revitalized look by morning.

Designed for use in textiles such as bedding and sleepwear, this new solution aims to transform nightly rest into a rejuvenating ritual, perfectly aligning with modern consumers' desire for holistic self-care.

The technology boosts the melatonin action, reduces the production of ROS (reactive oxygen species), stimulates the production of antioxidant genes and protein and stimulates the collagen gene expression.

+97% Biobased microcapsules

The Devan Sleep Tight technology is based on microencapsulation. First the active ingredients are incapsulated. Next, the biobased microcapsules are applied to the textile. The treated textiles touch our skin and the capsules break due to friction between the body and the textile. The content of the biobased capsules is then released and absorbed by the skin, while the volatile components of the active ingredients are simultaneously inhaled.

The microcapsules are readily biodegradable (tested according to the OECD 301B guideline). Possible applications are pillows, bed sheets, bed accessories, sleepwear, ...

Clinical study

33 healthy female and male subjects, aged between 18 and 60 years, with sleep problems, were using a treated pillow cover with R-Vital NTL 10015 Sleep Tight every night for 30 days. Each subject was required to fill out the Pittsburgh Sleep Quality Index and a quality of life (QoL) questionnaire, focused on the sleep quality, quality of life and overall well-being, before and after 30 days of using the respective product. The Pittsburgh Sleep Quality Index (PSQI) is a scientifically validated tool widely used to reliably assess and measure sleep quality.

The data shows that after 30 days of using a pillow case treated with R-Vital NTL 10015, subjects experienced notable improvements in several key areas of sleep and quality of life. The most significant changes were seen in sleep quality, sleep latency, sleep disturbances, reduction of daytime dysfunction and quality of life.

Showcased at Heimtextil 2025 in Frankfurt

Devan’s Sleep Tight technology was prominently featured at Heimtextil in Frankfurt, both by Devan and several of its partners. Notable among them were Crispim Abreu Lda and Lameirinho, two Portuguese companies specializing in bed linen and sleepwear, as well as Naturtex from Hungary, a leading producer of quilts and pillows.

The first productions are already underway, ensuring the technology will be available on the market by the second quarter of 2025. These alliances empower Devan Sleep Tight to deliver unparalleled value to manufacturers, retailers and consumers alike.

“Collaboration is at the heart of innovation,” says Marleen Van der Auwera, BU Leader of the Health & Wellness Division at Devan Chemicals. “By working closely with trusted industry leaders, we’re not just launching a product, we’re creating a solution that sets a new benchmark for sleep promoting textiles”.
