Embodiment 1

[0017] This silicone scar spray includes 80% neopentane, 10% 100cps silicone, and 10% 1000cps silicone.

[0018] Features: The spray solvent is neopentane, and silicone oil is a blend of 100 cps and 1000 cps. The spray is characterized by low viscosity, easy dispersion, high oiliness, and relatively weak adhesion to the skin.

Embodiment 2

[0020] This silicone scar spray includes 40% isopentane, 30% hexamethyldisiloxane, 20% 1000cps silicone, 3% polydimethylsiloxane cross-linked polymer, and phenyl dimethicone Oxyane 7%.

[0021] Features: The spray solvent is neopentane and hexamethyldisiloxane, the silicone oil is 1000cps silicone, and polydimethylsiloxane cross-linked polymer and phenyl polydimethylsiloxane are added at the same time. It can reduce the greasy feeling of the spray, increase the film-forming properties, and leave a glossy film on the skin surface after the solvent evaporates, with good adhesion and non-greasy.

Embodiment 3

[0023] This silicone scar spray includes octane 40%, pentafluoropropane 10%, cyclopentasiloxane 10%, 100cps silicone 5%, 12500cps silicone 20%, 5000000cps silicone 5%, polydimethylsiloxane Alkyl crosslinked polymer 5%, hexadecyl polymethylsiloxane 5%.

[0024] Features: The spray solvent is octane, pentafluoropropane, cyclopentasiloxane, silicone oil is 100cps, 12500cps, 5000000cps viscosity silicone, and polydimethylsiloxane cross-linked polymer and hexadecyl are added at the same time Polymethylsiloxane can reduce the greasy and sticky feeling of the spray and increase the film-forming properties. The 500000cps silicone has the characteristics of high viscosity and high molecular weight. It can fix the low viscosity silicone oil in its network structure and is not easy to fall off. After the solvent evaporates, it will leave a glossy film on the skin surface with good adhesion and non-greasy.

Abstract

The invention discloses a silicone scar spray. The silicone scar spray comprises silicone and a solvent as components, wherein the silicone accounts for 5-70%, and the solvent is soluble in the silicone and is volatile and non-toxic. Through combination of the silicone and the volatile solvent, a silicone spray which is convenient to use and rapid in film formation, can be tightly combined with skin and can significantly improve hypertrophic scars is prepared; the defects that the conventional cream or gel dosage form is greasy, difficult to smear and inconvenient to use are overcome; throughcoordination with other substances which can improve the efficacy and the skin feel of a product, diverse sprays can be prepared.

Description

Technical field [0001] The invention relates to a silicone scar spray, which belongs to the field of medicine. Background technique [0002] Silicone gel is widely used in the treatment of scars caused by burns, scalds and surgery. Studies have found that applying silicone on the skin surface can reduce the evaporation of skin moisture, promote the hydration of scar tissue, and inhibit the proliferation of fibroblasts and the deposition of collagen. The current scheme of silicone for scar repair can be compounded with water phase, oil phase and emulsifier to prepare a cream, or mixed with silicone oil of different viscosity and silicone oil modification to form a silicone gel. At present, silicone creams and silicone gels have disadvantages such as high viscosity, relatively greasy, difficult to apply, and inconvenient use. Summary of the invention [0003] The purpose of the present invention is to provide a silicone scar spray for removing scars. [0004] The purpose of the pre...
