방부제

화장품 방부제는 유통 기한 동안 미생물 증식을 억제하기 위해 수분을 함유한 배합에 첨가하는 INCI 기능 분류이며, EU에서는 해당 성분과 최대 사용 한도가 화장품 규정(EC No 1223/2009) 부속서 V에 규정되어 있습니다. 이 구성은 Annex V 등재 유효성분(phenoxyethanol, sodium benzoate, potassium sorbate, benzyl alcohol, chlorphenesin, methylisothiazolinone)과, 자체로는 Annex V 방부제가 아닌 두 가지 다기능 글리콜 부스터(caprylyl glycol, ethylhexylglycerin)를 포함합니다.

Phenoxyethanol is the most widely used single preservative, with an EU Annex V maximum of 1.0 percent. The real trade-off is pH window against compatibility: the organic-acid preservatives sodium benzoate and potassium sorbate function only in acidic systems below about pH 5.5 and lose function as pH rises, whereas phenoxyethanol works across a wider range and is often paired with a booster. Match the preservative to formula pH and confirm performance by challenge testing (ISO 11930). Confirm regulatory status for your application and jurisdiction.

Methylisothiazolinone is restricted in the EU to rinse-off products under Annex V, with leave-on use withdrawn; state this factually and confirm the rule for your market. Caprylyl glycol and ethylhexylglycerin are classified in the catalog under moisture control and emolliency, so they appear here as preservative-system boosters rather than standalone preservatives, and the seed labels were corrected accordingly. Benzyl alcohol is Annex V-listed and is also a declarable fragrance allergen.
