    Yep, it’s a fragrance that conjures up images of grandmothers tucking Lavender sprigs into linen cupboards. The grassy, floral, medicinal, and camphorous notes result in a vintage, quality feel.

    I have formulated Lavender in various products, including Patchouli Lavender Face Wash and Charcoal Cedarwood Lavender soap bar.

    While Lavender is a popular ingredient, it is not an easy one to blend effectively. But I found it worked very well with my saponified liquid soap bases. There seems to be a magical synergy between these two ingredients. One complements the other.

    Give it a try.

    Do you worry about the allergens found in lavender oil?

      Hi Perry,

      Yes, I do, and that’s why I do an allergen analysis for every formulation. This analysis is based on validated CoAs provided by the supplier.

        Sorry, a bit confused: by “allergen analysis” you mean the calculation based on the COA provided by your supplier, or proper Lab testing to check if the said COA is accurate?

    Hi Aniela,

    Yes, attached to my production facility, I had a fully staffed analytical lab, and we did test that the CoA supplied was accurate.

    @mikethair Could you please show the part of the COA where they list the components of the fragrance/essential oil? Usually this is shown in a separate document (allergen declaration) where all allergens are listed with their concentration.

    Also, how can you test all of them (keep in mind the list of allergens is now of 82)? They vary in nature and you require different protocols, chromatographic columns, stationary phases and solvents/solvent-mixtures? And of course, a MS which is very costly and hard to mantain.

      Sorry, I don’t have the original CoA because I am now out of the game and not manufacturing. I have retired.

    Its the only way I can sleep. I can no longer use it due to eczema but I put a drop on my pillow and it works better than ambien! I actually found it was the easiest EO to blend. It works in everything. It’s so powerful in healing scars and minor wounds that I’m really in awe of what it can do. But sadly can no longer use. It was also an EO in my pet bug repellant formula which was so effective that, after using for one season, I never had a single issue with fleas, bugs, ticks permanently. I stopped using all EO’s on pets with the exception of a calming air spray that is unusually effective. It has lavender and catnip.

    CAPB is a skin irritant. But when it is combined with another skin irritant like SLS in specific ratios, they both become gentle.

    Those allergens in lavender are allergen when used alone. But when those allergens are mixed with hundreds of other molecules in best ratios that they can have, wouldn’t it make a synergy and become not allergen?

    Isn’t it like saying this shampoo has SLS and CAPB, as both are irritating the skin when used individually, this shampoo would be very irritating?

      Hi Abdullah,

      OK, yes, there are allergens in Lavender, but with careful formulation, they never became a problem in my 20+ years of formulating and distributing products globally. But you need to know what you are doing when formulating lavender-containing products.

      Your statement here is total nonsense: ” But when those
      allergens are mixed with hundreds of other molecules in best ratios
      that they can have, wouldn’t it make a synergy and become not allergen?” The answer is NO!! NO!!! NO!!!
