Research Developments in Eyelash Adhesives

Self-adhesive glue for attaching false eyelashes that is simple, convenient, and quick to use. The glue composition contains specific proportions of butyl acrylate, isooctyl acrylate, methacrylic acid, hydroxyethyl acrylate, and water. The glue dries quickly to adhere the false eyelashes without the need for additional tools or application techniques.

An eye makeup cosmetic composition with improved adhesion and line durability for attaching artificial eyelashes and forming long-lasting eyeliner. The composition contains a combination of acrylate copolymers with different glass transition temperatures. The composition has 20-50% of a low Tg acrylate copolymer (-75 to -50°C) for adhesion, and 1-20% of a high Tg acrylate copolymer (0 to 15°C) for line durability. This balance resolves issues of poor adhesion with low Tg polymers alone, or poor line retention with high Tg polymers alone. The specific copolymers used are ammonium acrylate and styrene acrylate.

Fast-acting adhesive for attaching false eyelashes that reduces irritation and adverse reactions compared to traditional adhesives. The adhesive has two components, A and B, mixed at a ratio of 3-5 parts A to 1 part B. Component A contains acrylate, tetraisocyanate, polyurethane, and methyl cellulose ether. Component B contains charcoal powder, polyvinyl alcohol, dicumyl peroxide, and sodium acetate. The adhesive dries quickly and provides strong bonding for false eyelashes.

Hypoallergenic eyelash adhesive that is harmless to the human body and a manufacturing method for it. The adhesive composition contains cyanoacrylate, an acrylic styrene copolymer, pigment, and thickener. It provides excellent adhesion without using methyl methacrylate (MMA) and avoids harmful substances like formaldehyde and toluene. The acrylic styrene copolymer replaces MMA to improve adhesion without issues. The composition has little skin irritation and does not contain banned substances.

A viscous adhesive for false eyelashes that provides improved stickiness, hold time, and resistance to lifting and smudging. The adhesive contains a blend of solvents, humectants, emulsifiers, film formers, neutralizers, and preservatives. The formula balances ingredients to achieve the desired adhesive properties. The solvent is water, the humectant is propylene glycol, the emulsifier is polysorbate-80, the neutralizer is aminomethyl propanol, the film formers are rosin acrylate, C5-6 alkane/cycloalkane/terpene copolymer, styrene/acrylate copolymer, acrylate/ethylhexyl acrylate copolymer, and polyvinyl alcohol, and the preservatives are phenoxyethanol,

A composite eyeliner and false eyelash adhesive that eliminates the need for separate products and improves application efficiency. The eyeliner contains an acrylate copolymer adhesive and a thickener, like natural rubber latex, that also functions as a false eyelash adhesive. This allows applying the eyeliner to adhere false lashes without needing a separate adhesive step. The thickener helps prevent clumping of the eyeliner when applied over false lashes. The composite eyeliner can also contain other ingredients like pigment, fragrance, surfactant, conditioning agent, preservative, stabilizer, chelating agent, foaming agent, skin conditioning agent, emulsifying agent, de-greaser, lubricant, binding agent, suspending agent, water absorber, colorant, and humectant.

Photopolymerizable adhesive for attaching eyelash extensions that has excellent durability and water resistance, can be easily adhered even to wet eyelashes, and does not contain cyanoacrylate compounds. The adhesive contains a specific monomer, represented by the formula R1Or R5Is a hydrogen atom or a methyl group, R6Is a hydrogen atom, a methyl group, or a tert-butyl group, that adheres well to wet hair. The adhesive also has components like initiators, inhibitors, colorants, thickeners, and fillers.

An adhesive for attaching eyelash extensions that does not contain cyanoacrylate monomers, does not irritate the mucous membrane, and can be easily removed. The adhesive contains monofunctional monomers, polyfunctional monomers, and a photopolymerization initiator. It also optionally has inhibitors, colorants, thickeners, diluents, and removers. The adhesive cures upon exposure to light and has solubility in specific solvents. It provides better adhesion to eyelashes and extensions compared to traditional cyanoacrylate adhesives, while avoiding their issues like mucous membrane irritation and cyanoacrylate vapor diffusion. The solubility allows easier removal of adhesive from lashes.

Cosmetic composition with improved thread-forming and adhesion properties for applications like mascara. The composition contains a silicone-modified polysaccharide and an acryl-silicone graft copolymer in combination. This provides a cosmetic with excellent thread formation and adhesion, especially when applied to eyelashes. The ratio of silicone-modified polysaccharide to acryl-silicone graft copolymer is important for optimal thread forming and viscosity. For eyelash cosmetics, a ratio of 90:10 to 10:90 provides improved volume, length, and glossiness.

An adhesive emulsion for cosmetics like false eyelashes that provides high adhesion to skin, water resistance, and good feel. The adhesive emulsion contains a copolymer made of methacrylic acid and alkyl acrylate, preferably with a glass transition temperature (-80 to -50°C). Blending this emulsion with other cosmetic ingredients improves adhesion, water resistance, and skin affinity compared to natural rubber latex adhesives. The copolymer emulsion can be used as the main adhesive component for cosmetics or added in smaller amounts to improve adhesion and water resistance of cosmetics without rubber allergy concerns.

Improving the adhesion of eyelash extensions to natural eyelashes to increase the duration of the extensions. The method involves applying a coating solution containing components like silver, silk, keratin, and acrylates to the natural eyelashes before attaching the extensions. This coating penetrates the gaps in the eyelash cuticles to improve adhesion between the extensions and natural lashes. The coating can also be applied to the extension tips for better adhesion.

Fast-bonding and long-lasting adhesive composition for attaching synthetic or natural keratin materials like hair or eyelashes to human hair or eyelashes. The composition contains medical grade cyanoacrylate monomers, organic polymer thickeners, inorganic fillers like fumed silica, and bonding accelerators. The thickeners and fillers increase viscosity for easy application and prevent running. The composition provides fast bonding time, high viscosity, and shelf life of at least 6 months. The medical-grade cyanoacrylates are safe for human use compared to industrial-grade ones.

Adhesive for attaching false eyelashes to the skin that provides high adhesive strength, durability, and water resistance while allowing easy removal of the false eyelashes. The adhesive is a pressure-sensitive formulation containing water and an acrylic copolymer composed of 2-ethylhexyl acrylate, methyl methacrylate, ethyl acrylate, and methacrylic acid. The specific ratios of these monomers in the copolymer provide optimal properties for false eyelash adhesion and ease of removal.

Self-adhesive artificial eyelashes that can be worn semi-permanently and look natural because they are bonded with an instant adhesive that cures without whitening. The eyelashes have a short section at the base overlapping with the natural eyelashes, and an adhesive is applied there to bond them together. The adhesive is odorless, transparent, and doesn't whiten when cured, so it doesn't contrast with the dark eyelashes. The eyelash tips are black, sharply curved, and free to move naturally.

Eyelash adhesive composition that provides excellent initial adhesion, dries quickly, has water resistance, and can be easily removed with water. The composition contains 5-18% film-forming polyvinyl alcohol or polyvinyl acetate, 2-10% film-forming and adhesion enhancing aids, 0-7% moisturizing and softening agents, and 0-4% initial adhesion reinforcing agents. The composition allows quick drying, good adhesion, water resistance, and easy removal compared to traditional latex adhesives.
