Inolex launches bio-based sensory enhancer
The ingredient is derived from coconut and is designed to be biodegradable, with ready biodegradability expected based on EpiSuite modelling.
USA – Inolex has launched SustOleo™ Embrace, a multifunctional sensory enhancer for skin care, body care and fragrance applications.
The coconut-derived amino ester is designed to leave skin radiant, hydrated and smooth while extending fragrance longevity for up to 20 hours.
SustOleo™ Embrace changes from a lightweight oil during application to a soft, cushiony finish on the skin.
It provides slip and playtime without feeling heavy or greasy, and leaves an elastomer-like after-feel.
“Following the success of LexFeel® Enhance MB in sun care, SustOleo™ Embrace marks our second product launch this year,” said Miao Wang, vice-president of research and development and commercialisation at Inolex.
She added that the company’s patented amino ester platform creates interactions with skin and fragrance that combine sensory benefits with performance.In a controlled in-vivo study, a serum containing 7.5% SustOleo™ Embrace reduced the appearance of dry skin scaliness by 33% and improved skin smoothness by 30% after a single application.
Separate visual testing with formulations containing 5% of the ingredient found that all participants reported visible improvements in skin smoothness and elasticity.
The ingredient is also designed to support fragrance performance. In a 24-hour odour-potency test, it extended fragrance release on skin for up to 20 hours.
A 48-hour test conducted at 50°C found that d-limonene loss was 0.79% in a formulation containing SustOleo™ Embrace, compared with 11.01% in a control without a film former.
In comparative testing with jojoba oil and 350 cSt dimethicone, SustOleo™ Embrace spread more easily than dimethicone and showed a spreading profile similar to jojoba oil.
It also delivered greater substantivity without noticeable tackiness or unwanted residue.
According to Inolex, this combination of spreadability, cushion and lasting after-feel offers a sensory profile that is uncommon among naturally derived, silicone-free ingredients.
Art Knox, president of Inolex, said the ingredient addresses three consumer priorities: how a product feels, how the skin looks after application and how long its fragrance lasts.
SustOleo™ Embrace is 85% naturally derived, with a Natural Origin Index of 0.85 under ISO 16128.
It is also palm-free, vegan, cruelty-free, Halal-certified and Kosher-compliant.
The ingredient is available for sampling and can be used in silicone-free skin-care, body-care and fragrance formulations, either as a silicone alternative or alongside existing sensory systems.
