Hydrosal® SalCool

Description

HydroSal® SalCool

HydroSal® SalCool (HS SC) : is an innovative cooling agent designed using advanced HydroSal® encapsulation technology. It contains three types of cooling actives (Triple Cooling Actives) encapsulated within sub-micron spheres. This technology helps deliver the cooling agents directly to the sensory nerve endings in the lower layers of the skin and releases them continuously and sequentially, resulting in a long-lasting cooling sensation that is significantly more sustained than conventional menthol. Importantly, it is odorless.

HS SC utilizes the HydroSal® core-and-shell encapsulation system, which encapsulates three cooling agents—Methyl Diisopropyl Propionamide, Menthyl Lactate, and Ethyl Menthane Carboxamide—within the core of sub-micron spheres. This innovation enhances the penetration of the active ingredients to the sensory nerve endings and enables Sequential Release of the cooling actives. This allows users to experience a prolonged and continuous cooling sensation without irritation.

Key Active Ingredients: Triple Cooling Actives (Three Cooling Agents)

HS SC contains three primary synthetic cooling agents that work synergistically to deliver a comprehensive cooling sensation:

• Methyl Diisopropyl Propionamide: Provides a quick-onset cooling effect.

• Menthyl Lactate: Offers a long-lasting and stable cooling sensation.

• Ethyl Menthane Carboxamide: Delivers a durable cooling effect with very minimal odor.

Mechanism of Action of HydroSal® SalCool (HS SC)

HS SC works through a mechanism known as Neurocosmetics, which acts directly on the sensory nervous system without actually lowering the physical temperature of the body.

1. Targeted Delivery

HydroSal® technology creates sub-micron spheres that act as carriers to deliver the three cooling actives directly to the sensory nerve endings located in the lower epidermal layer.

2. Sequential and Sustained Release

• The encapsulating shell controls the release of each cooling agent in a sequential manner, meaning each ingredient activates and lasts at different time intervals.

• This slow and controlled release results in a consistent, long-lasting cooling sensation.

3. Cooling Without Strong Odor

Since the actives are non-menthol cooling agents and are encapsulated, HS SC is odorless, making it ideal for formulations requiring a delicate fragrance profile or products where a specific scent should be preserved.

Benefits

• Long-Lasting Cooling: Provides extended freshness, ideal for post-workout products or heat-relief formulations.

• Odorless & Versatile: Suitable for fragranced formulas or products designed for sensitive or intimate areas.

• Suitable for Sensitive Skin: The controlled-release technology delivers cooling without irritation, even for delicate skin types.

Summary of the Manufacturer’s Research — Outstanding Innovation: Longer-Lasting Cooling Sensation with No Odor

This study focuses on comparing the performance of HydroSal® 2 SalCool (HS SC)—a cooling agent delivered through sub-micron sphere encapsulation—with free menthol, in terms of cooling intensity and the duration of the cooling sensation.

Test Method

Sample Preparation:
A leave-on formula was prepared containing both HS SC and free menthol at the same concentration (1%).

Application:
The products were applied to the inner forearm of the test participants.

Evaluation:
Participants rated the cooling intensity on a scale of 0–5 at regular intervals over a 60-minute period after application.

Test Results

• During the first 30 minutes, both HS SC and free menthol produced a similar cooling sensation, with peak intensity scores around 4.5.

• After 40 minutes, the cooling sensation from free menthol began to decline rapidly.

• At the 60-minute mark, HS SC still provided a significantly higher cooling intensity compared to free menthol.

Conclusion

Thanks to its sub-micron sphere encapsulation technology, which contains three cooling agents, HS SC delivers a slow-release mechanism that gradually delivers the actives to sensory nerve endings. As a result, it provides a noticeably longer-lasting cooling sensation than conventional menthol. Additionally, it is odorless and suitable for sensitive skin, aligning with the concept of Neurocosmetics.

Research Study

A study from Rutgers University, USA, found that multi-layer encapsulation technology can extend the retention time of cooling agents on the skin by more than 200% compared to un-encapsulated substances. Furthermore, it significantly reduces skin irritation (p<0.05). This technology is highly effective in controlling the sustained release of active ingredients and helps maintain skin moisture for a longer duration.
