Liquid Cinnamate-Based Sunscreen Actives for Bulk Cosmetic Manufacturing
SPF filter OM-Cinnamate supplied in a 1 liter volume is a liquid organic UV absorber used across the global sun care industry in formulations such as daily facial creams, body lotions, sunscreen sprays, and after-sun products with claimed protection factors. It belongs to the section UV and SPF Filters for Cosmetics, gathering substances that absorb ultraviolet radiation in the UV-B range and partially UV-A, reducing photodamage to skin. The one liter pack is aimed at manufacturers running continuous or high-volume production lines, contract manufacturers of sun care and daily protection products, and laboratories that need consistent raw material behavior batch after batch during scaled-up manufacturing.
The most common worldwide application of this filter is in daily moisturizers with built-in sun protection, lip balms with SPF claims, body sprays, and color cosmetics such as tinted foundations, BB and CC creams, powders and primers offering an added protective function. Beyond skin care, organic UV filters of this chemical family are used in hair care products, particularly leave-in sprays protecting color-treated hair from sun fading, and in certain polymer and packaging applications where photostabilization of the material is required. Global demand for this ingredient continues to grow alongside the rising production of everyday moisturizers with integrated SPF and the trend toward multifunctional formulas combining skin care benefits with sun protection.
The filter is typically added to the oil phase of an emulsion during the mixing of lipid components, once the batch reaches a working temperature of approximately 70 to 75 degrees Celsius, since the substance blends well with oils, esters, and silicones under moderate heating. Usage levels in finished formulations commonly range from 5 to 10 percent depending on the target protection factor and combination with other filters. To increase the sun protection factor and broaden the absorption spectrum, this filter is frequently combined with other UV absorbers such as Covabsorb EW, which strengthens UV-A protection, or Benzophenone-4, used to widen the absorption range and stabilize the formula. It is also compatible with the smaller pack of similar active material, Ethylhexyl Methoxycinnamate, which is convenient for pilot testing before scaling up to industrial batches.
When designing formulations it is important to consider photostability of the finished product, since prolonged light exposure can reduce the effectiveness of certain organic filters over time, which is why industrial recipes often include antioxidants and stabilizers, and combine organic filters with mineral ones to achieve broad spectrum protection. The raw material should be stored in a tightly sealed container, in a dry area away from direct sunlight and heat sources, at room temperature, avoiding sharp temperature fluctuations and prolonged air exposure once the packaging has been opened. Proper storage conditions directly affect the retention of the claimed filtering activity throughout the shelf life of the product.

Heat
the oil phase containing shea butter and emulsifying wax to 75 degrees Celsius
and dissolve OM-Cinnamate and Benzophenone-4 into it with continuous stirring
until fully uniform. Separately heat the water phase with glycerin to the same
temperature, then slowly pour it into the oil phase while homogenizing until a
stable emulsion forms. Once the batch cools to 40 degrees, add the preservative
and vitamin E, mix thoroughly, and fill into light-protective containers
suitable for industrial packaging lines.
