Description

Technical Field

[0001] This invention relates to the field of hair glue, and in particular to a liquid glue that can be used for hair growth. Background Technology

[0002] With increasing life pressures and environmental changes, the number of people experiencing hair loss continues to rise, making wigs an important means of aesthetic and psychological compensation. However, the glue used to attach wigs can further damage the skin and hair follicles, potentially exacerbating hair loss. Therefore, the market urgently needs an innovative product that can safely adhere wigs while improving the scalp microenvironment and promoting hair health.

[0003] Minoxidil is a commonly used ingredient in hair loss treatments, and the aforementioned problems can be addressed by adding it to wig glue. However, most commercially available glue products primarily contain acrylates, such as ethyl α-cyanoacrylate, which requires acetone or isoacetone as a fast-drying solvent. Minoxidil is insoluble in acrylates, and ethyl α-cyanoacrylate, after forming a film, hinders the transfer of minoxidil to the scalp. Furthermore, acetone can cause minoxidil to crystallize or precipitate, preventing it from making good contact with the scalp and thus rendering it ineffective. Since minoxidil cannot be directly added to conventional wig glue, a new formulation for wig glue containing minoxidil needs to be developed. Summary of the Invention

[0004] The purpose of this invention is to provide a liquid adhesive that can be used for hair growth, in order to solve the above-mentioned problems.

[0005] The technical solution of the present invention is as follows: a liquid adhesive that can be used for hair growth, comprising the following components: 60–75% adhesive, 2–5% minoxidil, 0.5–1% auxiliary active ingredient, 1–3% solubilizer, 1–3% penetration enhancer, 1–3% thickener, 2–5% softener, 1–2% soothing agent, 0.05–0.1% preservative, and the balance being water.

[0006] The adhesive is an acrylate copolymer or polydimethylsiloxane. It is used to provide the adhesive's tack. Polydimethylsiloxane, in particular, offers better biocompatibility and breathability.

[0007] The auxiliary active ingredients are one or more of caffeine, arborvitae leaf extract, ginseng extract, ginger extract, and Polygonum multiflorum extract. These substances enhance the scalp care performance of the product of this invention.

[0008] The solubilizer is propylene glycol or ethanol. The solubilizer is used to promote the dissolution of minoxidil and acts as a dispersant for minoxidil.

[0009] The penetration enhancer is propylene glycol or azone. The penetration enhancer is used to increase the transdermal absorption of minoxidil.

[0010] The thickener is carbomer or xanthan gum. Thickeners are used to adjust the viscosity of the glue, making it less likely to flow. Furthermore, thickeners improve the adhesiveness.

[0011] The flexibility agent is triethyl citrate. The flexibility agent is used to reduce the brittleness of the colloid.

[0012] The soothing agents are panthenol, dipotassium glycyrrhizate, or bisabolol. These agents are used to reduce allergic irritation and soothe the scalp.

[0013] The preservatives are sodium benzoate, ethylhexylglycerin, or potassium sorbate. These preservatives are used to reduce microbial contamination.

[0014] Minoxidil is incorporated into the adhesive via sustained-release microcapsules. The use of mature microcapsule sustained-release technology extends the duration of action of minoxidil.

[0015] The beneficial effects of this invention are as follows: This invention incorporates hair growth ingredients such as minoxidil. Minoxidil has good permeability, and the adhesive has good adhesion. All ingredients in this invention are safe and non-toxic, suitable for use on the skin surface, and contain soothing ingredients to reduce the occurrence of allergies. It is a safe product that improves the scalp microenvironment and promotes hair growth. Detailed Implementation

The adhesive is an acrylate copolymer or polydimethylsiloxane. The auxiliary active ingredient is one or more combinations of caffeine, Platycladus orientalis leaf extract, ginseng extract, ginger extract, and Polygonum multiflorum extract. The solubilizer is propylene glycol or ethanol. The penetration enhancer is propylene glycol or azone. The thickener is carbomer or xanthan gum. The softener is triethyl citrate. The soothing agent is panthenol, dipotassium glycyrrhizate, or bisabolol. The preservative is sodium benzoate, ethylhexylglycerin, or potassium sorbate. Minoxidil is incorporated into the adhesive via sustained-release microcapsules.

[0018] The preparation method is as follows: First, powdered minoxidil is dissolved in a co-solvent and dispersed using a homogenizer to prepare a minoxidil solution. An excipient active ingredient is dissolved in an aqueous solvent to prepare an excipient active ingredient solution. The minoxidil solution, the excipient active ingredient solution, and the remaining materials are mixed together to prepare the product of this invention.

[0019] Further preferably, minoxidil can be formulated into sustained-release microcapsules. The core material of the microcapsules is prepared by dissolving minoxidil in a co-solvent, and the microcapsules are prepared using ethyl cellulose or polyurethane as the wall material. The prepared microcapsules are then mixed with other materials. Example 1
