Petrolatum (CAS 8009-03-8), as a derivative product of the petroleum and natural gas industry, has become an irreplaceable functional material in the fields of medicine, cosmetics and industry due to its chemical inertness, strong water retention and wide compatibility. Although its low-toxicity characteristics support daily use, attention should be paid to the control of its potential carcinogenic impurities (such as polycyclic aromatic hydrocarbons). Suggestions when making a purchase
Pharmaceutical/skin care uses: Select "Pharmaceutical White Vaseline" (UV absorbance ≤0.50);
Industrial rust prevention: Prioritize hydrofining process products.
Vaseline is classified into four types based on its degree of refinement and application:
Pharmaceutical Vaseline (GB 1790-86)
Ingredients: Highly refined, with extremely low content of polycyclic aromatic hydrocarbons (UV absorbance ≤ 0.50@290nm)
Purpose:
Ointment base (such as burn ointment, skin repair agent)
Skin care products (moisturizing, preventing cracking)
Oral ulcer protective film
Industrial Vaseline (SH/T0039-90)
Characteristics: Contains trace impurities (such as sulfides ≤0.00017%)
Purpose:
Metal anti-rust grease
Rubber softener, leather wetting agent
Common Vaseline (GB 6732-86)
Application: Glass fiber drawing emulsion, lubrication of rubber products
Capacitor Vaseline (GB 6733-86)
Usage: Impregnating insulating material for capacitors
Toxicity:
Low acute toxicity (oral LD₅₀ in rats: 39,000 mg/kg)
Potential risk: It may contain trace amounts of polycyclic aromatic hydrocarbons (carcinogen R45), and the UV absorbance needs to be controlled
Food/Pharmaceutical compliance
FDA/WHO permits its use in food (baked goods ≤0.15%, confectionery ≤0.2%)
Comply with the pharmacopoeia standards of various countries (such as USP, EP)
Operation protection:
Avoid contact with eyes and wear gloves when operating
Store in a cool place at ≤30°C, away from oxidants
