ITEM 1: PRODUCT IDENTITY AND NOMENCLATURE

Description: Ethylhexylglycerin is an alkyl glyceryl ether derived from vegetable glycerin. It is a clear, colorless to pale yellow, viscous liquid. It is widely used in cosmetic and personal care products as a preservative booster, moisturizer, emollient, and deodorant active ingredient. It is known for its low toxicity, broad pH stability, and excellent tolerance profile. Its antimicrobial activity is particularly effective against Gram-positive bacteria and synergistically enhances the efficacy of preservatives such as phenoxyethanol.

Description: Ethylhexylglycerin is an alkyl glyceryl ether formed by attaching a 2-ethylhexyl ether group to a glycerin molecule. The molecule contains two hydroxyl groups (-OH) and one ether group (-O-). This structure imparts both hydrophilic (water-loving) and lipophilic (oil-loving) properties, giving it amphiphilic (surface-active) character. This amphiphilic structure enables interaction with microbial cell membranes, providing antimicrobial activity. Being derived from vegetable glycerin, it is sourced from renewable materials.

ITEM 3: PHYSICAL APPEARANCE AND FORM

Description: Ethylhexylglycerin is a clear, colorless to pale yellow, viscous liquid with a slight characteristic odor. It is supplied in high purity and contains no visible sediment or turbidity.

ITEM 4: PHYSICAL PROPERTIES

Description: Ethylhexylglycerin has a density of approximately 0.962 g/cm³ at 20°C and a refractive index of 1.448. Its melting point is approximately -12°C. The boiling point is 325°C, indicating low volatility. It is slightly soluble in water (approximately 1 g/L) but readily soluble in alcohol and glycols. Its aqueous solution is neutral (pH 5.5-7.0).

ITEM 5: THERMAL PROPERTIES

Description: Ethylhexylglycerin has a low melting point of approximately -12°C and remains liquid over a wide temperature range. Its boiling point is 325°C, indicating very low volatility. The flash point is above 100°C. It is thermally stable up to 150°C, which is sufficient for most cosmetic processing conditions.

ITEM 6: SOLUBILITY AND MISCIBILITY

Description: Ethylhexylglycerin is slightly soluble in water but completely miscible with most organic solvents including ethanol, methanol, isopropanol, propylene glycol, glycerin, acetone, ethyl acetate, oils, and silicone oils. This broad solubility profile makes it easy to incorporate into a wide range of cosmetic formulations.

ITEM 7: PURITY AND ANALYTICAL SPECIFICATIONS

Description: Ethylhexylglycerin is supplied in high purity (≥98.0%). Low water content and acid value indicate high quality and product stability. Heavy metal content is strictly controlled to ensure safety for cosmetic applications.

ITEM 8: COSMETIC APPLICATIONS (PRESERVATIVE BOOSTER)

Preservative Synergy:

Description: Ethylhexylglycerin is used in cosmetic formulations as a preservative booster. It is particularly effective in synergy with phenoxyethanol. It exhibits antibacterial, antifungal, and mild antiviral activity. Its surface-active properties allow it to affect the surface tension of microbial cell membranes, enhancing the efficacy of preservative systems.

ITEM 9: DEODORANT AND ODOR CONTROL APPLICATIONS

Mechanism of Action:

Description: Ethylhexylglycerin provides deodorant efficacy by inhibiting the growth of odor-causing bacteria (particularly Gram-positive bacteria). It is a preferred ingredient in aluminum-free natural deodorant formulations. It prevents odors caused by bacteria, yeast, and fungi on the skin.

ITEM 10: MOISTURIZING AND SKIN CARE APPLICATIONS

Description: In skin care products, Ethylhexylglycerin functions as a moisturizer and emollient. Being a glycerin derivative, it attracts and retains moisture in the skin. It also helps extend product shelf life and contributes to preventing unpleasant odors that may develop over time.

ITEM 11: SHAMPOO AND HAIR CARE APPLICATIONS

Description: In shampoos and hair care products, Ethylhexylglycerin is used as a preservative booster and moisturizer. It helps prevent microbial growth and extends product shelf life. It also contributes to preventing bacteria and fungus-related issues on the scalp.

ITEM 12: SUNSCREEN APPLICATIONS

Description: In sunscreen formulations, Ethylhexylglycerin is used as a preservative booster. It helps prevent microbial growth and extends product shelf life. Its moisturizing properties also enhance skin comfort.

ITEM 14: REGULATORY STATUS

ITEM 15: SAFETY AND TOXICOLOGICAL PROFILE

Description: Ethylhexylglycerin has a low toxicity profile (LD50 > 2000 mg/kg). At recommended usage levels, it is non-irritating to the skin and non-sensitizing. It may cause mild eye irritation. It is not classified as a carcinogen, mutagen, or reproductive toxicant. It is readily biodegradable and has low ecotoxicity.
