SensaLuxe DF: a biodegradable and inclusive ingredient for dry hair conditioning
In response to the question “would you like to have a good hair condition?”, there is no doubt there will only be positive answers. The quest for healthy hair is global, and it cannot be assigned to a specific range of consumers or even to a specific hair type, or style. According to Euromonitor, there is an increasing number of people who are looking for hair conditioning ingredients, with a category growth of 7.5% in 2021, to achieve hair that looks and feels good. But when it comes to finding the most suitable product for our hair, it is not that simple. Not all ingredients will have benefits on every hair type. On top of that, efficacy is not the only purchasing criteria, consumers are now looking for sustainable options and putting a greater emphasis on a sense of well-being, which reduces the scope of choices.
SensaLuxe DF is a naturally derived, biodegradable and non-aqua toxic ingredient that delivers consumer perceivable improvements for hair that is smoother, softer, and more manageable. SensaLuxe DF is effective in both rinse-off and leave-on treatments, providing a novel alternative to traditional hair care actives to enhance the condition of damaged hair in its dry state, regardless of curl type. Let’s now explore what’s behind its features and benefits, and how we managed to demonstrate its efficacy on a wide range of hair types.
Dry state conditioning with SensaLuxe DF
The world is finally embracing differences, and when it comes to hair care, it means demonstrating product performance on multiple hair types and its ability to be inclusive. It requires being relevant and having a good definition of every hair type. In that sense, existing curl type classifications allow the market to gain a better understanding of hair types and to have an overall consistency.
It considers curve diameter, curl length, number of waves and number of twists, leading to a classification of hair into 8 different categories (as seen below in Figure 1), from straight to extremely curled hair in a consistent manner..At Croda, we decided to follow the scientific approach developed by L’Oreal

On top of that, let’s not forget about sustainability. Consumer awareness of environmental damage was steadily growing for years, but 2019 and 2020 were very pivotal with a collective “eco anxiety” rise leading to greater expectations. For hair care, the preservation and protection of the oceans is important. Consumers want to take care of themselves but not at the detriment of the environment, and with a lot of hair care products rinsed off and released into the water, it is important for stakeholders to ensure it is harmless.
Our hair care experts have been working hard to develop a solution that would tackle all this consumer criteria, and we are very pleased to introduce SensaLuxe DF as a brilliant hair conditioning ingredient. It provides a full approach by offering inclusive performance, sensory experience, and sustainable credentials.
It was important to us to begin its development by better understanding the reasons behind the high demand for hair conditioning solutions and how SensaLuxe DF could help. Everyday grooming practises such as combing and styling, as well as chemical treatments and UV exposure, are a major cause of hair damage. Repetitive combing of the hair damages the fibre, depletes its natural lipid layer, and contributes to inter-fibre friction, which consumers recognise as rougher, weaker hair making it more difficult to comb. The look and feel of the hair are also impacted and cuticle damage results in dull, rough, unmanageable hair.
To effectively improve dry state conditioning of hair, the conditioning agent must exhibit a natural tendency to “slip” in order to reduce friction force when consumers touch their hair. However, traditional conditioning agents that give positive conditioning performance in the wet state, such as quats, do not tend to show the same conditioning performance in the dry state due to the absence of water that serves as the lubricant. The long, branched chain structure of SensaLuxe DF is designed to provide a lubricating effect on different hair types, for luxurious, touchably smooth hair, without the build-up associated with some traditional hair conditioning ingredients, like silicones.
SensaLuxe DF performance has been validated through several substantiation tests and 6 different hair types have been explored from the curl classification, as shown in Figure 1 above. For instrumental testing, dry friction assessments demonstrated excellent surface smoothing properties of SensaLuxe DF on bleached type 2 and type 4 hair and combing and detangling evaluations showed its great conditioning properties. Positive results have also been obtained following bending force tests (Figure 2), proving that SensaLuxe DF can deliver incredibly soft hair.

Salon evaluations reinforced the value proposition, as SensaLuxe DF outperformed the control for both wet and dry attributes when tested on relaxed type 6/7/8 hair and colour-treated type 2 hair. SensaLuxe DF also presented similar benefits to dimethicone for dry attributes when tested on type 3/4 and type 5/6/7 hair (Figure3). Evaluation results demonstrated the capacity of SensaLuxe DF to offer consumer-perceivable improvements in the sensory feel of hair from type 2 to type 7 hair.

SensaLuxe DF presents great consumer-perceivable benefits, delivering a luxuriously smooth and soft hair in the dry state. With studies performed on most of hair types, there is no doubt its exceptional conditioning properties will please all the consumers looking for hair that looks and feels good.
