Product Brief: Humectant G-25Humectant G-25 is a high-performance cosmetic-grade hydrating agent, presenting as a colorless to pale yellow viscous liquid at 25°C. It meets strict quality standards: pH 5.0-7.0 (1% aqueous solution), hydroxyl value 128-158 mgKOH/g, and moisture content ≤1%.
It excels in long-lasting moisture retention, also acting as a lubricant and foam improver. Compatible with water/ethanol and most surfactants, it integrates seamlessly into water-based skincare (lotions/creams), haircare (shampoos/conditioners), and toiletries. Safe for sensitive skin, it supports efficient formulation for bulk production needs.
Product Advantage
Excellent Solubility and Stability: Humectant G - 25 is soluble in water and ethanol, insoluble in hydrocarbons. It stays stable within the pH range of general cosmetics and is compatible with cationic, anionic, and non - ionic surfactants.
Effective Moisturizing Performance: With a hydroxyl value of 128 - 158 mgKOH/g, it can effectively retain moisture, providing good hydration for related products.
High Purity: Its moisture content is ≤1%, ensuring high purity and reducing the possibility of microbial growth, which is beneficial for product stability and shelf - life.
Versatile Applications: It serves as a moisturizer, lubricant, and foam modifier in cosmetics and toiletries, and also as an intermediate in betaine synthesis.

Product Operate Guide
For water-based skincare (lotions/creams) or haircare (shampoos/conditioners): Add 1-5% Humectant G-25 to the formula during production. Mix with water/ethanol or surfactants at 25-40°C, stirring gently until fully dissolved (avoids clumping).
For chemical synthesis (fatty acid esters): Follow reaction-specific dosages. Store unused product in a dry, ventilated place to keep moisture content ≤1% and maintain its performance.
FAQ
1. Q: Can Humectant G-25 be used in oil-based cosmetic formulas?
A: No, it can't. Humectant G-25 is soluble in water and ethanol but insoluble in oils. It's specifically formulated for water-based products like lotions or shampoos to ensure stable integration and effective moisturization.
2. Q: Is it safe to increase Humectant G-25's dosage beyond 5% in formulas?
A: It's not recommended. The 1-5% range balances moisturization and formula stability. Exceeding 5% may cause product stickiness or reduce compatibility with other ingredients—test small batches first if adjustments are needed.
3. Q: Can Humectant G-25 be used in products for sensitive or baby skin?
A: Yes, it can. With a pH of 5.0-7.0 (matching skin's natural pH) and non-irritating properties, it's gentle enough for sensitive/baby skin. It also works with mild surfactants, avoiding skin discomfort.
4. Q: What happens if Humectant G-25 is stored in a humid environment?
A: Humid conditions may raise its moisture content above the ≤1% standard, weakening its moisturizing ability. Always store it in a dry, ventilated place to preserve its performance and extend shelf life.
5. Q: Does Humectant G-25 conflict with common cosmetic preservatives?
A: No, it doesn't. It's compatible with most cationic, anionic, and non-ionic surfactants, as well as common preservatives (e.g., phenoxyethanol), ensuring no formulation conflicts.
