소개
Glycerol, commonly known as glycerin, is a colorless, odorless, sweet-tasting viscous liquid. As a triol, it has strong hygroscopicity and excellent solvency, and it is non-toxic to the human body.
General chemical properties include being miscible with water and alcohols in any proportion. Common chemical reactions: esterification with fatty acids to form triglycerides; nitration with nitric acid; and oxidation under the action of strong oxidants.

응용 프로그램
- Cosmetics & Skincare: Acts as a humectant and solvent, absorbing and locking in moisture to keep the skin hydrated.
- 식품 산업: Used as a sweetener, humectant, and preservative to improve texture and extend shelf life.
- 화학 합성: Used in the manufacture of alkyd resins, polyurethanes, and glyceride-based surfactants.
저장
Should be stored in a cool, dry, and well-ventilated warehouse. Due to its strong hygroscopicity, containers must be kept tightly sealed to prevent absorbing moisture from the air. Keep away from fire, heat sources, and strong oxidants.
취급 및 주의사항
Handle with care to prevent packaging damage. Wear standard protective clothing and gloves. Although it is non-toxic, exposure to high concentrations may cause mild irritation to the eyes and skin. If accidental contact occurs, rinse with plenty of water.
공식
Hand Cream Base: Water (70%) + Glycerol (10%) + Stearic Acid (15%) + Emulsifier (5%).
Function: Glycerol acts as the core humectant in this formula, attracting moisture to the stratum corneum, preventing the cream from drying out during storage, and providing the skin with long-lasting hydration.
포장
PE 백으로 안감을 댄 섬유 드럼 또는 골판지 상자에 포장합니다. 맞춤형 포장은 요청 시 가능합니다.
자주 묻는 질문
Are glycerol and glycerin the same substance?
네. 글리세롤은 화학 명칭이고, 글리세린은 가장 널리 사용되는 일반 명칭입니다. 둘 다 정확히 같은 화학 물질을 가리킵니다.
Can I apply 100% pure glycerol directly to my skin?
권장하지 않습니다. 순수 글리세린은 흡습성이 매우 강하기 때문에 피부 속 수분을 흡수합니다. 사용 전에는 일반적으로 물이나 플로럴 워터에 10%~20% 농도로 희석해야 합니다.
Is glycerol flammable?
Glycerol is a combustible liquid but has a relatively high flash point (160°C). It is not easily ignited at room temperature but will burn at high temperatures or when exposed to an open flame.
