Emulsifier SG-100 (PEG-100 Stearate) is a non-ionic surfactant produced by Haian Guoli Chemical Co., Ltd. It is not classified as a dangerous chemical and is not listed in the 'Catalogue of Hazardous Chemicals.' Based on existing toxicological and ecotoxicological data, this product has no GHS hazard classification and poses no significant harm to the human body or the environment under normal industrial use conditions.
From a human health perspective, the acute oral LD₅₀ in rats is greater than 5000 mg/kg, indicating a practically non-toxic level; the primary skin irritation index is less than 0.5, with no significant irritation; eye irritation is mild and reversible, not meeting the criteria for serious eye damage classification; skin sensitization tests show no sensitization; Ames test is negative, indicating no genotoxicity; and there is no evidence of reproductive toxicity. Overall, this product exhibits prominent safety characteristics of low toxicity and low irritation.
From an environmental impact perspective, the 96-hour LC₅₀ for fish is greater than 100 mg/L, indicating low ecotoxicity; according to OECD 301 test, the degradation rate over 28 days is greater than 60%, classifying it as readily biodegradable, meaning it will not accumulate in the environment for a long time and has a minor impact on aquatic ecosystems.
| Safety Indicator | Test Data | Conclusion |
|---|---|---|
| Acute toxicity (rat oral LD₅₀) | > 5000 mg/kg | Practically non-toxic level |
| Skin irritation | Primary skin irritation index < 0.5 | No significant irritation |
| Eye irritation | Mild reversible irritation | Not meeting serious eye damage classification |
| Skin sensitization | — | No sensitization |
| Genotoxicity (Ames test) | Negative | No genotoxicity |
| Reproductive toxicity | — | No evidence of reproductive toxicity |
| Fish acute toxicity (96h LC₅₀) | > 100 mg/L | Low ecotoxicity |
| Biodegradability (OECD 301, 28 days) | Degradation rate > 60% | Readily biodegradable |
Given its excellent safety, SG-100 is widely used in cosmetics and personal care products (creams, lotions, sunscreens, etc.) as an O/W emulsifier and solubilizer, maintaining good safety performance even in direct skin contact applications. In the textile industry, it is used as a softener and antistatic agent; in the plastics industry, as an internal lubricant; and in pesticide formulations, as an emulsifier. It can be confidently used under conventional processing conditions.
It is recommended to optimize the dosage in the formulation based on specific application scenarios and emulsification requirements. Typically, the dosage as an emulsifier in cosmetics is 1%-5%, and the specific amount should be determined through experiments to achieve the optimal ratio.
