{"product_id":"btms-25","title":"BTMS-25 Australia | Behentrimonium Methosulfate Conditioning Emulsifier","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eBTMS-25 (Behentrimonium Methosulfate and Cetyl Alcohol) is a self-emulsifying cationic conditioning emulsifier — a popular, cost-effective entry-level conditioning emulsifier widely used in Australian DIY and small-batch hair conditioner, leave-in conditioner, and conditioning cream formulation. A white to off-white waxy flake, it forms the backbone of rinse-off conditioners, detangling sprays, hair masks, and conditioning body lotions with a single, easy-to-use ingredient.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eLike its higher-concentration counterpart BTMS-50, BTMS-25 works through cationic (positive charge) chemistry. Hair fibres carry a net negative charge — damaged, bleached, and chemically treated hair even more so. BTMS-25 is positively charged, so it is attracted to and deposits a conditioning film onto the negative surface of each hair fibre. This deposited film smooths the cuticle, reduces friction and tangles, eliminates static, adds shine, and creates the soft, manageable feel that defines a well-formulated conditioner. This mechanism is unique to cationic conditioning emulsifiers — it cannot be replicated by standard non-ionic emulsifying waxes.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe key difference from BTMS-50 is the active concentration. BTMS-25 contains 25% Behentrimonium Methosulfate (the cationic conditioning active) versus 50% in BTMS-50. The remaining 75% in BTMS-25 is Cetyl Alcohol — a fatty alcohol that contributes emolliency, emulsification support, and a creamy, rich texture to finished formulations. This lower active concentration means BTMS-25 is used at higher percentages in formulations to achieve equivalent conditioning to BTMS-50, but it also contributes more of the luxurious, opaque, thick-bodied texture that many formulators and consumers associate with premium conditioner — making it a popular choice when a rich, creamy conditioner texture is the priority.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eNot yet listed in store — contact us to enquire about availability and pricing.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eSPECIFICATIONS\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eINCI Name: Behentrimonium Methosulfate (and) Cetyl Alcohol\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCAS Number: 81646-13-1 (Behentrimonium Methosulfate); 36653-82-4 (Cetyl Alcohol)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCommon Name: BTMS-25, Conditioning Emulsifier BTMS-25\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eActive Concentration: 25% Behentrimonium Methosulfate \/ 75% Cetyl Alcohol\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCharge Type: Cationic (positively charged) — deposits conditioning film onto negatively charged hair\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGrade: Cosmetic Grade\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAppearance: White to off-white waxy flakes or pellets\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOdour: Faint characteristic waxy — essentially odourless in formulation\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMelting Point: 50–60°C\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003epH (in formulation): Produces slightly acidic to neutral pH; typical finished conditioner pH 4.5–6.5\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHLB Value: Approximately 11 (oil-in-water emulsification)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSolubility: Dispersible in warm water above melting point; soluble in oils at elevated temperature\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePhase: Oil phase \/ emulsifier phase — melt with oil-phase ingredients at 70–75°C\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eShelf Life: 2+ years when stored correctly\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eStorage: Store sealed in a cool, dry place away from moisture and heat\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eNote: BTMS-25 uses Cetyl Alcohol (C16) as the co-ingredient; BTMS-50 uses Cetearyl Alcohol (C16\/C18 blend) — this contributes to slightly different texture profiles in finished formulations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eBTMS-25 vs BTMS-50 — THE KEY DIFFERENCE\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis is the question every formulator working with BTMS products asks.

Both components must appear on your finished cosmetic product ingredient list. Note the difference from BTMS-50 — BTMS-50 uses Cetearyl Alcohol (a C16\/C18 blend) while BTMS-25 uses Cetyl Alcohol (C16 only). This difference in the co-ingredient contributes to slightly different texture profiles in finished formulations.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eShould I use BTMS-25 or BTMS-50?\u003c\/strong\u003e\u003cbr\u003eThe right choice depends on your formulation goals. Choose BTMS-25 when you want a rich, thick, creamy conditioner texture — the higher cetyl alcohol content produces a classic opaque, luxurious conditioner body. Choose BTMS-50 when conditioning efficiency and lower usage rates are priorities — BTMS-50 delivers more conditioning per gram and is better suited to lightweight leave-ins and efficient production formulas. Many experienced formulators keep both: BTMS-50 as the conditioning workhorse and BTMS-25 for formulations where thick, creamy texture is the marketing or consumer feel priority.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhat percentage of BTMS-25 do I use in a conditioner?\u003c\/strong\u003e\u003cbr\u003eA typical rinse-off conditioner uses 8–15% BTMS-25. At 8–10% the conditioner is lighter and suitable for fine or normal hair. At 12–15% the conditioner is richer and more suitable for dry, damaged, thick, or coarse hair. Compared to BTMS-50 (which is used at 3–8%), BTMS-25 requires roughly double the amount to achieve equivalent conditioning — reflecting its 25% active concentration vs 50% in BTMS-50.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCan I blend BTMS-25 and BTMS-50 in the same formulation?\u003c\/strong\u003e\u003cbr\u003eYes — blending is common and effective. A typical approach: use BTMS-50 at 4–6% as the primary conditioning active for efficiency, then add BTMS-25 at 3–5% for additional cetyl alcohol body and texture richness. This gives you the conditioning efficiency of BTMS-50 with the thick, creamy texture contribution of BTMS-25's higher cetyl alcohol content. Adjust ratios to match your desired conditioning intensity and product viscosity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDoes BTMS-25 work in leave-in conditioners?\u003c\/strong\u003e\u003cbr\u003eYes — at lower usage rates of 3–6%. At these rates it creates a light emulsion that coats hair with a conditioning film without leaving it feeling heavy or greasy. For very fine hair, stay at 3–4% and keep oil additions minimal. For thick or coarse hair, 5–6% with a small amount of lightweight oil (argan, camellia) works well. Ensure full melting before water phase addition for a smooth, lump-free result.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eHow do I melt BTMS-25 for formulation?\u003c\/strong\u003e\u003cbr\u003eBTMS-25 melts at 50–60°C. Add to your oil phase in a double boiler or dedicated wax melter, heating to 70–75°C for full incorporation. Confirm all flakes are fully liquefied before adding the water phase — undissolved flakes create lumpy texture in the finished conditioner. Heat the water phase to the same temperature before combining to prevent thermal shock and ensure a smooth emulsion.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhy does BTMS-25 create a thicker conditioner than BTMS-50?\u003c\/strong\u003e\u003cbr\u003eBTMS-25 is 75% Cetyl Alcohol versus 50% Cetearyl Alcohol in BTMS-50. Cetyl Alcohol (C16) has a slightly higher melting point and crystallises into a more structured wax matrix on cooling compared to the C16\/C18 blend in BTMS-50. This more structured fatty alcohol matrix contributes a thicker, creamier, more opaque body to finished formulations — the classic look and feel of a premium thick conditioner.
