C12-15 alkyl benzoate
CAS 68411-27-8

Applications

1. In the aspect of cosmetics and personal care, C12-15 Alkyl Benzoate, a color carrier, is widely used in sunscreen products. C12-15 Alkyl Benzoate dissolves oil-soluble UV filters, pigments, polyalkylsiloxanes and various other ingredients, so it is recognized by the FDA as one of the pigment carriers in sunscreen products.

2.C12-15 Alkyl Benzoate is applied in sunscreens, creams, lotions and hair conditioners and other products. Additionally, it has excellent spreadability and penetrability to help reduce greasiness of the formulations. Most importantly, as an efficient pigment carrier and solvent, it easily dissolves hard-to-dissolve raw materials such as oil-soluble UV filters, pigments and polysiloxanes, ensuring the product’s high physical stability.

3.In hair care products, C12-15 Alkyl Benzoate acts synergistically with cationic surfactants, such as Cetrimonium Chloride and Behentrimonium Chloride, delivering outstanding synergy to improve dry hair conditions. Besides, as a high-polarity lightweight oil, it works alongside cationic polymers to adsorb onto the surface of damaged hair strands, improving the instant conditioning effect of hair conditioners.

Specifications

Advantages

1. Produced via an advanced rectification process, the product is colorless and odorless with no residual fusel alcohols and by-products. In the premium skincare and perfume formulations, an extremely low odor level means that clients don’t need additional masking agents to maintain the original fresh elegant fragrance of the formula.

2.The product’s acid value is controlled at ultra-low levels, ensuring excellent chemical stability across a wide pH range. In complex formulations containing a variety of active ingredients (such as sunscreens, anti-aging serums), our material is not hydrolyzed or oxidized, and in turn effectively extends the shelf life of finished products and reduces the risk of discoloration or phase separation in formulations.

3.Thanks to its excellent refractive index and viscosity indicators, it imparts excellent spreadability and a lightweight skin feel to formulations. Compared with conventional oils, our C12-15 Alkyl Benzoate provides an invisible, silky, non-heavy application experience, making it suitable for summer lightweight sunscreens and daily lotions.

4.As an excellent sunscreen auxiliary agent, the polarity of the product is precisely controllable. Besides, C12-15 Alkyl Benzoate significantly improves solubility and uniform dispersion of inorganic and organic UV filters (e.g., titanium dioxide, avobenzone). This means that clients enable easy formulation of high-SPF, uniformly textured products, while lowering the risk of UV filter precipitation and enhancing the sun protection efficacy of finished products.

5.Each batch passes full specification testing, such as refractive index, APHA color and water content, which comply with global regulatory requirements for cosmetic ingredients, with full traceability throughout the production process. In conclusion, it realizes effective cost reduction for clients’ quality control and compliance.

FAQ

Q1: What is the core function in sunscreen products？
A: As a solvent and carrier in sunscreen products, C12-15 Alkyl Benzoate dissolves oil-soluble organic UV filters (e.g., avobenzone), preventing UV filter precipitation, and enabling uniform spreading of UV filters on the skin surface. Boasting superior emollient performance and recognized safety compliance under FDA standards, the ingredient boosts SPF performance and delivers more stable film formation in commercial sunscreen products globally.

Q2: How to improve the skin feel of skincare products and reduce greasiness?
A: C12-15 Alkyl Benzoate has unique low viscosity and excellent spreadability. Besides, as a skin feel modifier, it can dilute and balance heavy oils, such as mineral oil and vegetable oils, in formulations to transform tackiness into a silky and lightweight skin feel when you used it. In other words, your creams and lotions can deliver a fluid, water-like melt upon application, which are absorbed by the skin.

Q3: What benefits does this ingredient bring when formulated with cationic raw materials in hair care formulas?
A: C12-15 Alkyl Benzoate has a strong synergistic effect with cationic surfactants such as the quaternary ammonium salts used in hair conditioners. For example, it works alongside cationic polymers to adsorb onto the surface of negatively charged hair cuticle, repairing damaged hair cuticles and providing non-oily lubricious feel. For this reason, it leaves hair smooth without a heavy, greasy weighing-down effect after application, making it ideal for conditioning dry and frizzy hair.

Q4: As a supplier, which key quality control indicators should we pay attention to？
A: Clients pay attention to this aspects:
Color: Water-white clear liquid--The lower the color index, the better the purification process.
Acid Value: The lower the acid value, the better the product. In contrast, the high acid value may suffer impaired stability or develop unpleasant odors.
Refractive Index: Between 1.480 and 1.490. It is the key index to determine the product purity and ingredient proportion.
Moisture content: Low moisture content helps improve the storage stability of the final skincare formulation.

Q5: Does it cause allergic reactions or skin irritation?
A: No. First of all, C12-15 Alkyl Benzoate is recognized as a mild emollient with low skin irritation potential in the cosmetics industry. Secondly, it has excellent chemical inertness and non-comedogenic, making it ideal for all skin types, including sensitive skin. Finally, as one of the safest oily additives in the industry, it is widely used in premium sunscreens and eye formulations.
