High Purity Ceteareth-25 Granules | Cosmetic Grade Emulsifier Bulk Supplier

Ceteareth-25 (Cetearyl Alcohol Polyether-25, CAS 68439-49-6) is a non-ionic emulsifier synthesized by the condensation of cetearyl alcohol with 25 moles of ethylene oxide. It appears as a white waxy solid or granules.

With an HLB value of approximately 15.2–16.0 and strong hydrophilicity, it is an ideal emulsifier for formulating O/W (oil-in-water) emulsions. Compared to Ceteareth-20, Ceteareth-25 offers superior gel-forming and thickening capabilities.

It is widely applied in creams, lotions, sun care products, hair conditioners, hair dyes, makeup removers and other personal care formulations.

As a professional source manufacturer, we supply high-purity Ceteareth-25 with stable bulk supply capacity and complete technical documentation (COA/MSDS).

1. Creams & Lotions: Core O/W Emulsifier Component

Ceteareth-25 is a classic emulsifier for preparing oil-in-water (O/W) emulsions. When compounded with Ceteareth-12 or Cetearyl Alcohol, it forms a more stable emulsifying system:

Face & moisturizing creams: Delivers a fine emulsifying system and imparts a rich, luxurious texture to the product.

Lotions: Helps achieve a lightweight skin feel and rapid absorption.

Sunscreens: Evenly disperses sunscreen agents to boost SPF performance and enhance sensory experience.

Recommended dosage: 1% – 5% (can be used in combination with other emulsifiers)

2. Hair Care Products: Dual Conditioning & Emulsifying Functions

Hair conditioners: Emulsifies oils to improve smoothness and combability of hair.

Hair dyes: Acts as an emulsifier and thickener to stabilize hair color formulations.

Hair gels/styling products: Improves product texture and spreadability for easier application.

3. Makeup Removers & Cleansing Products

Cleansing oils/balms: Effectively emulsifies makeup and excess oils for thorough cleansing.

Facial cleansers: Serves as an auxiliary emulsifier to enhance the overall cleansing experience.

4. Personal Care Products

Body washes: Thickens and stabilizes product texture for a more luxurious lather.

Shaving creams: Helps form fine, dense foam for a smooth shaving experience.

5. Pharmaceutical Creams

Topical drug carriers: Used as an emulsifying base for the preparation of dermatological creams and ointments.

1. What is Ceteareth-25 (CAS 68439-49-6)?

Ceteareth-25 is a non-ionic emulsifier formed by the condensation of cetearyl alcohol with 25 moles of ethylene oxide. It appears as a white waxy solid or granules. Compared with Ceteareth-20, it features stronger gel-forming and thickening properties, making it a high-performance O/W (oil-in-water) emulsifier for cosmetics and personal care products.

2. What is the HLB value of Ceteareth-25?

The HLB value of Ceteareth-25 is approximately 15.2–16.0, with strong hydrophilicity, which makes it an ideal emulsifier for preparing stable O/W emulsions.

3. What are the key advantages of Ceteareth-25?

Superior emulsifying & thickening performance: Efficiently emulsifies most oils and fats, with stronger gel-forming and thickening capabilities than Ceteareth-20.

Versatile functionality: Acts as an emulsifier, solubilizer, foam stabilizer and thickener in formulations.

Wide temperature stability: Maintains stable emulsification across a broad temperature range.

Excellent compatibility: Compatible with anionic, cationic and non-ionic surfactants, as well as various cosmetic and pharmaceutical ingredients.

4. What is the recommended dosage of Ceteareth-25?

The recommended addition level is 1%–5% in formulations. It can be used alone or in combination with other emulsifiers (such as Ceteareth-12 or cetearyl alcohol) to achieve a more stable emulsifying system.

5. In which products is Ceteareth-25 widely used?

Skin care: Creams, lotions, sun care products

Hair care: Hair conditioners, hair dyes, hair gels/styling products

Cleansing: Makeup removers, facial cleansers, body washes

Other personal care: Shaving creams

Pharmaceuticals: Topical dermatological creams and ointments

6. What is the difference between Ceteareth-25 and Ceteareth-20?

Both are non-ionic O/W emulsifiers with similar HLB values, but Ceteareth-25 has stronger gel-forming and thickening properties due to its higher ethoxylation degree (25 moles of EO vs. 20 moles for Ceteareth-20), making it more suitable for formulations requiring richer texture and higher viscosity.

7. Is Ceteareth-25 compatible with other cosmetic ingredients?

Yes. Ceteareth-25 shows good compatibility with anionic, cationic and non-ionic surfactants, various oil systems, sunscreens, preservatives, fragrances and active pharmaceutical ingredients.

8. Do you supply bulk Ceteareth-25?

As a professional source manufacturer, we provide high-purity Ceteareth-25 with complete COA and MSDS documentation, and support stable bulk supply for global cosmetic and pharmaceutical customers.
