Several non-toxic bioadheisives have been originally developed for soft tissues, but is being applied towards cosmetic and fragrance applications. The technology platforms employ proprietary methods of bonding that avoids the pitfalls inherent in other tissue glues based on acrylates and urethanes.
Two platform technologies are described:
Caproglu Platform is a solvent free, liquid adhesives that bonds within seconds into a rubber foam on wet surfaces and mimics the elasticity of soft tissues. CaproGlu’s unique formulation allows incorporation of hydrophobic pigments, fragrances, and cosmetic compounds in a liquid to adhesive rubber delivery. It contains no acrylates, initiators, or free radical preservatives that cause skin allergies in other bioadhesives. It is free of biopolymers and contains no animal or human derived components.
OxyGlue Platfrom is a liquid organic adhesive that bonds upon exposure of oxygen to form antimicrobial coatings and films. It is highly UV absorbing and has strong chromogenic properties.
TECHNOLOGY FEATURES & SPECIFICATIONS
CaproGlu/OxyGlue can be applied towards hair and skin coatings, where other bioadhesives cannot.
CaproGlu/OxyGlue can be applied towards encapsulation/dissolving fragrance or sunblock compounds, where other bioadhesives cannot.
The synthetic methodology does not require biopolymers from human or animal origins. The formulations does not raise ethical concerns in terms of animal treatment or disease transmission (e.g. virus/prions).
Both platforms have a scalable yield production, from laboratory batch production to continuous reactor-scale production. Thus, the production benefits from economy of scale. All synthetic protocols have previously been found scalable.
These bioadhesives have long-term shelf storage of 12 months or greater without the inconvenience of product reconstitution by a technical expert.
Bioadhesive application by brush, spray, 3D printing, inkjet, or syringe is feasible.
CaproGlu requires no dilution in aqueous or organic solvents—in their neat form, they can dissolve other organic compounds, such as fragrances and sunblock compounds. No other bioadhesive has this unique characteristic without employing acrylate compounds.
Adhesive platforms may be adapted to improve the performance of pre-existing fast moving consumer goods (FMCG) or consumer packaged goods (CPG). This includes the categories of sunblock preparations, skincare preparations, skin and hair pigments, henna-based and ink-based temporary tattoos, manicuring preparations, makeup preparations, makeup fixatives, costume makeup, and immobilization and long-term delivery of fragrance preparations with one-time use applicators. Any application that could benefit from a liquid to solid conversion with subsequent immobilization to soft flexible surfaces and substrates.
CaproGlu/OxyGlue are synthetic formulations that does not require biopolymers from human or animal origins, addressing an unmet need in the cosmetic and fragrance industries.
CaproGlu/OxyGlue relies on a novel method of adhesion without the use of acrylates, removing concerns of skin allergies and contact dermatitis.
CaproGlu can be applied towards encapsulation/dissolving hydrophobic compounds for unmet aesthetic applications on skin and hair substrates. Cured CaproGlu remains transparent for concealed applications.
