AC-VBE

AC-VBE is a mild warming agent identified by chemical formula C12H18O3, and molecular weight 210.27 g/mol, combining a clear technical profile with an assay of not less than 98%. Compared with conventional warming ingredients such as capsicum and ginger extract, which are known for stronger.

Its warming action is associated with vanilloid receptor 1 (VR-1/TRPV1), a heat-sensing receptor, while its recommended use level of 0.05%-0.5% allows formulators to build a long-lasting thermo-sensory effect without excessive raw-material loading or strongly stimulating effect.

1.Rapid onset with prolonged warmth sensation
At only 0.05%-0.5%, AC-VBE can generate a clear warming sensation in about 2 minutes, and the thermal perception can remain for several hours, which is especially valuable for products that need a stable, long-lasting sensory effect rather than a short initial heat spike. This time-to-sensation profile helps creams, massage oils, slimming products, and body-care formulas deliver a more premium and more controlled warming experience.

2.Low impurity content and high purity
AC-VBE is produced through a direct one-step reaction with butanol instead of a conventional two-step halogenation and dechlorination route, helping reduce impurity burden while maintaining an assay above 98%. This manufacturing approach also supports a colorless to pale yellow or almost transparent appearance and a pure characteristic vanillin odour, which are important quality indicators for premium personal care formulations with stricter sensory and appearance requirements.

3.Mild and low-irritation
Traditional warming materials such as capsicum and ginger extract are associated with stronger burning, itching, and irritation, while AC-VBE provides a gentler and longer-lasting warming profile with a similar rapid onset of about 2 minutes and a duration of several hours. This balance between onset speed, sensory persistence, and lower irritation makes it more suitable for daily-use formulas, including cleansers, facial masks, body care, hair care, and spa products.

4.Low dosage, high sensory efficiency
The effective use level of AC-VBE is only 0.05%-0.5%, which helps formulators achieve a clear warming response without pushing the formula with excessive active load. Combined with an assay of ≥98%, oil solubility, and liquid form at room temperature, this low-dosage efficiency supports cleaner textures, easier incorporation into emulsions and anhydrous systems, and better control over final sensory intensity across multiple product types.

5.Excellent synergy with cooling agents
AC-VBE works effectively with cooling agents such as Menthol lactate, allowing a hot-cold sensory profile to be built with greater depth and longer perception time than a single sensory active alone. When the formula is designed within the recommended 0.05%-0.5% usage range and appropriate oil-phase conditions, this synergistic effect can intensify the warming effect, the cooling effect, or both, depending on the intended product positioning.

1.Generates a warming sensation
AC-VBE contains the same vanillyl structural group associated with heat perception and interacts with VR-1/TRPV1 in sensory cells, a receptor system linked to temperatures above 43°C. This activation pathway allows AC-VBE to produce a noticeable warming sensation in about 2 minutes and maintain the sensory effect for several hours, making it suitable for products that need immediate perception and lasting sensory retention in one formula.

2.Supports microcirculation for body contouring
After receptor activation, sensory cells release CGRP, or calcitonin gene-related peptide, which promotes vasodilation and stimulates microcirculation. Increased local blood flow contributes to a warmer tissue feel and supports the sensory positioning of body contouring, massage, slimming, and body-care products, especially when AC-VBE is used at the recommended 0.05%-0.5% level for a sustained 
thermo-sensory response.

3.Enhances sensory performance in cleansing and skincare systems
AC-VBE is oil-soluble and available as a liquid raw material, allowing it to be incorporated into cream, lotion, cleanser, facial mask, spa, emulsion, lip balm, and soap applications while maintaining a practical use level of 0.05%-0.5%. With HLB 8 as the best fit and pH 6.0-6.5 as the most suitable range, it helps formulators create a more refined warming profile in both rinse-off and leave-on systems.

4.Supports scalp and hair-care concepts
AC-VBE is also suitable for hair-care and scalp-focused products, where a rapid warming onset of about 2 minutes and a duration of several hours can create a stronger active-use perception than conventional non-thermal systems. Together with its microcirculation-supporting mechanism and low recommended dosage of 0.05%-0.5%, it is well positioned for stimulating scalp-care and warming hair-treatment concepts.

Q1: What is AC-VBE?
A1: AC-VBE is Vanillyl Butyl Ether, a thermosensitive warming agent with chemical formula C12H18O3,  assay ≥98%. It is supplied as a colorless to pale yellow liquid with a mild characteristic vanillin odour and is designed for long-lasting warming sensory applications in personal care.

Q2: How much AC-VBE should be used?
A2: The recommended dosage is 0.05%-0.5%, a low-use range that can still generate a noticeable warming sensation in about 2 minutes and maintain the effect for several hours. This dosage window gives formulators flexibility to adjust intensity across cleansing, body-care, massage, and leave-on product formats.

Q3: How fast does AC-VBE work?
A3: AC-VBE can create a noticeable warming sensation in about 2 minutes after application, and the thermal perception can last for several hours. 

Q4: What products can use AC-VBE?
A4: AC-VBE can be used in cream, lotion, cleanser, massage cream or oil, slimming products, spa products, warming cream, facial mask, body care, hair care, emulsion, soaps, pain-relief style products, and lip balms.

Q5: Can AC-VBE be paired with cooling agents?
A5: Yes. AC-VBE shows strong synergy with cooling agents such as Menthol lactate, helping intensify the warming effect, the cooling effect, or both within one formula. This makes it suitable for premium thermo-sensory concepts that require longer-lasting perception and a more distinctive hot-cold user experience.
