Creating a sunscreen that protects skin and leaves the desired feel is not always easy. You need effective UV protection, a stable formula and ingredients that mix well without making the product feel too heavy on the skin. At the same time, you need to meet the expectations of high SPF performance and pleasant skin feel.

Here, the Ethylhexyl Triazone UVB filter, or EHT or octyl triazone, comes to the rescue. It provides UVB absorption with excellent photostability and mixes well with oil-based formulations.

For the sunscreen manufacturer, these are valuable parameters that help to create reliable, high performance sun care products for changing customer expectations.

What Makes Ethylhexyl Triazone a Powerful UVB Filter?

Ethylhexyl Triazone (EHT) is part of the triazine family of organic UV filters. EHT is a second-generation UV filter for sunscreen, which was developed to provide efficient UVB protection with improved stability.

Its peak absorption is at about 314 nm, while the UVB spectrum is between 280-320 nm. Moreover, the high absorption efficiency of EHT, which allows it to achieve excellent UVB protection even at low concentrations.

Why Oil Solubility Matters in Sunscreen Formulation?

One of the big advantages of EHT is that it dissolves in oil-based ingredients. EHT is an oil-soluble UVB filter for sunscreen, which mixes well with oils and emollients used in cream, lotion and other sun care product formulations.

This opens up great formulation flexibility, as EHT can be used in various formats, including those with a light texture. At the same time, the compatibility with other UV filters allows the creation of products with effective UV protection.

Photostability: The Key to Reliable Sun Protection

A sunscreen filter loses its performance under the sun and thus fails to adequately protect the skin.

EHT is a preferred UVB absorber for its photostability, which makes it valuable for the development of stable sunscreen formulas for daily use and outdoor activities. Moreover, the possibility of combining it with other UV filters contributes to the creation of high performance sunscreen products. However, EHT mainly protects against UVB and thus it is necessary to complement it with other UV filters that protect against UVA.

Key Benefits of EHT for High SPF Sunscreens

What makes formulators choose EHT? The benefits of this UVB absorber go far beyond just UV protection.

• High UVB efficiency: delivers good absorption at relatively low concentrations.
• Excellent photostability: helps maintain performance even under sunlight.
• Formulation flexibility: combines with suitable UVA and UVB filters.
• Oil compatibility: ideal for incorporation into oil phases used in various sunscreen formulations.
• High SPF support: acts as a valuable high SPF sunscreen raw material for meeting high performance standards.

These are the parameters that make EHT a useful additive for manufacturers creating effective and comfortable sun care products.

Finding a Reliable EHT UV Filter Supplier in India

The quality of ingredients is one of the most important factors that determine the quality of sunscreen products. To help ensure the reliability of their formulation, manufacturers should choose a trusted EHT UV filter supplier India, who provides the required documentation, along with consistent technical data and bulk supply of this additive.

In addition, working with a reliable triazine-based UV filter manufacturer also helps formulators get high-quality products with stable characteristics, which is critical for their formulation development process.

Choosing a UVB filter can become a gamble, and the stress is understandable. You may be looking for a high SPF, a good skin feel, and stability of your formula. On top of this, there are ever-changing regulations to keep in mind. Below is a brief, jargon-free overview of the differences between ethylhexyl triazone and octyl methoxycinnamate.

We will discuss their properties, application tips, and limitations. By the end of this post, you will know which UVB filter is better for your formula.

What Do These Two UVB Filters Do?

To start with, here is basic information about both filters. EHT is an oil-soluble filter peaking at 314 nm. OMC is another name for octyl methoxycinnamate. On a label, you can find ethylhexyl methoxycinnamate or octinoxate (OMC). It is a UV filter peaking at 310 nm. Both filters block UVB rays causing sunburns. Neither of them provides actual UVA coverage, so you will have to use a UVA filter in addition to these two.

Which Filter Provides Higher SPF per Percent?

As a rule, EHT is more efficient per percent. It absorbs UVB intensely, so a little of the filter goes a long way. Thus, a higher SPF can be achieved using less filter. OMC is less efficient per gram, but it usually is cheaper, but need to add with higher dosage to achieve the desired SPF...

Which One Remains Stable in Sunlight?

This is where these filters differ. Ethylhexyl triazone is photostable, so its activity remains high in the sunlight. OMC is photodegradable. Under UV irradiation, it transforms into a cis-isomer with lower absorbance. Also, it can affect avobenzone, a UVA filter, decreasing its efficiency.

Which One Is Easier to Formulate?

In this regard, OMC is much easier. Being a liquid, it mixes easily with other ingredients. It can help dissolve some other filters used in your formula. EHT is a white powder requiring polar emollients to remain soluble. Otherwise, crystallisation may occur at low temperatures.

However, it can be used in water-resistant sunscreens successfully. Nonetheless, it should be tested in your final formula.

What Do the Rules Say?

Now let's move to regulatory aspects. According to Annex VI of Regulation (EC) No 1223/2009 in the EU, a maximum concentration for EHT is 5% and 10% for OMC. In the US, according to the OTC monograph, octinoxate (OMC) is allowed up to 7.5%. However, EHT is not included in the monograph and cannot be used in US OTC sunscreens at the moment.

Besides, since 2021, Hawaii has banned the sale of sunscreens containing octinoxate. The review of UV filters by regulatory authorities continues, so avoid such claims as "reef-safe" or "worldwide approved". Instead, look at the latest rules in markets where you want to sell your formula.

Which One Should You Pick?

Choose EHT if you are interested in a high SPF and photostability of your formula and if it is allowed in the market you address.

Otherwise, go with OMC if cost and processability are your priorities. However, some companies combine both filters with others.

Conclusion

Neither filter wins all the time. It all depends on your priorities, budget, and market. Therefore, pay attention to all aspects mentioned above when choosing a filter.
