An antiperspirant water-in-silicone formulation asks one emulsifier to manage a demanding internal water phase, dissolved active salts, a silicone or mixed oil external phase, the desired roll-on or gel flow and a consumer expectation for glide, low tack and controlled residue. The label silicone emulsifier does not define the phase ratio, carrier, polymer architecture or process window. A grade that works in a light skin lotion may separate, thicken or lose sensory quality when the aqueous salt load and package geometry change.
Juyou JY-R1290-1 and JY-R1230 are relevant water-in-oil and water-in-silicone emulsifier routes for formulation screening. Their published profiles differ, so buyers should not treat them as interchangeable. This guide turns the formula brief into a supplier comparison, laboratory trial, commercial specification and RFQ while keeping antiperspirant efficacy, safety and regulatory claims inside the finished-product validation program.
Define the product format and emulsion architecture first
State whether the target is a clear or opaque roll-on, soft solid, cream, gel, stick component or another delivery format. Map the internal aqueous phase, antiperspirant active solution, humectants and water-soluble ingredients separately from the external silicone and organic oil phase. Record the intended internal-phase percentage, oil blend, fragrance, powders, structuring agents and viscosity window. The same INCI list can behave differently when phase ratio and addition order change.
Clarify whether the project requires water-in-silicone only or a mixed water-in-silicone-and-organic-oil system. Also record the filling temperature, pump and roll-ball geometry, package venting, consumer climate and shelf-life target. Procurement should send this architecture with the sample request so the proposed emulsifier matches the real external phase rather than an idealized laboratory base.
- Roll-on, gel, cream, soft solid or other format
- Antiperspirant active identity, solution basis and internal-water-phase level
- Silicone fluids, organic emollients, fragrance and powder package
- Target viscosity, appearance, clarity, payoff and filling temperature
- Market, package, storage climate and finished-product claim constraints
Shortlist JY-R1290-1 and JY-R1230 by formulation role
The JY-R1290-1 Silicone Emulsifier profile describes an alkyl- and polyether-modified surfactant for water-in-oil or water-in-silicone systems. It is positioned for high internal aqueous phase, cold mixing, broad oil and active compatibility, and sensory adjustment from light lotion to richer cream. Those points make it a logical first screen when the brief combines salt solution, high water phase and a cold-process objective.
The JY-R1230 Silicone Emulsifier profile describes a silicone polyether route for low-viscosity water-in-oil and water-in-silicone systems, with compatibility across silicone oils, organic esters and their mixtures. It also identifies antiperspirant and deodorant use. Compare both grades at equal active basis and within the real oil blend. A lower use level or a clearer vial is not enough if the formula misses filling, stability, residue or package targets.
- JY-R1290-1: screen high internal phase and cold-process requirements
- JY-R1230: screen low-viscosity W/O or W/Si and mixed-oil compatibility
- Keep carrier and active-content differences in every dose comparison
- Request a written recommendation for the disclosed active and phase ratio
Build a grade-specific incoming specification
The published JY-R1290-1 profile lists a colorless to pale-yellow transparent liquid, viscosity of 600 to 2500 square millimeters per second at 25 degrees Celsius, relative density of 0.930 to 0.965, approximate HLB of 3 to 5 and 100 percent active content. The JY-R1230 profile lists its own appearance, viscosity, density, refractive-index, flash-point and HLB fields. Treat these pages as screening data and request the current TDS, SDS, sample COA and proposed commercial specification before locking a formula.
Define the fields that influence manufacturing and substitution: exact INCI or chemical description, active content, carrier, appearance, odor, viscosity, density, refractive index, water, volatile profile and any cyclic-siloxane or restricted-substance information required by the destination. Every numerical field needs a method and temperature. Ask which values are guaranteed for release, which are typical, and how much advance notice applies to a composition, carrier, site or method change.
- Exact grade, INCI, active content and carrier identity
- Appearance, viscosity, density and refractive-index methods
- Restricted-substance and regional personal-care document needs
- Lot number, manufacture date, shelf life and retention sample
- COA fields and formal change-control notice period
Formulate around the antiperspirant active salt and water phase
The active solution can change ionic strength, density, pH and interfacial behavior. Use the exact commercial active grade and solution concentration in the emulsifier screen. Record whether the formula contains aluminum salts, aluminum-zirconium complexes or another permitted active, and confirm the applicable regional monograph or cosmetic rule with the finished-product regulatory team. The raw-material supplier should not be asked to convert a formulation trial into an efficacy or compliance claim.
Prepare the internal phase with controlled water quality and temperature. Check compatibility with humectants, neutralizers, preservatives, chelants and water-soluble actives before emulsification. In the external phase, compare each silicone fluid and organic emollient at the intended ratio. Fragrance can destabilize the interface or alter clarity, so include the production fragrance rather than approving an unfragranced base only.
- Commercial active solution and actual salt concentration
- Water quality, pH, density and humectant package
- Silicone and organic oil identity, viscosity and ratio
- Fragrance, powder, preservative and structurant challenge
- Finished-product efficacy, safety and regulatory test plan
Establish a repeatable cold or hot manufacturing process
Cold-process suitability can reduce heating time, but it does not remove the need for process control. Pre-blend the emulsifier into the correct external phase, prepare the aqueous active phase separately, and add the internal phase at a controlled rate under defined shear. Record blade type, tip speed, vessel geometry, batch temperature, addition time and endpoint. Excessive shear can entrain air or change viscosity, while insufficient shear can leave a broad droplet distribution and weak stability.
Compare cold and warm routes only if both are realistic for production. Measure batch temperature rise, mixing torque, aeration, deaeration time and final viscosity after a fixed maturation period. Define the order for fragrance, powders and heat-sensitive ingredients. During scale-up, match mixing time and energy per volume rather than copying laboratory revolutions per minute. The process specification should include acceptable appearance and viscosity before filling.
- Phase preparation and verified addition order
- Temperature, shear device, tip speed and addition time
- Droplet-size or microscopy endpoint where available
- Deaeration, maturation and pre-fill release checks
- Scale-up rule for mixer and vessel geometry
Run a stability and package-compatibility matrix
Evaluate the complete formula at ambient, elevated and low temperature, with freeze-thaw or temperature cycling where the distribution route requires it. Track appearance, color, odor, viscosity, droplet distribution, creaming, syneresis, sediment, active crystallization and redispersibility. Centrifuge screening can help rank candidates but does not replace real-time and accelerated storage. Test more than one batch and include the incumbent formula as a benchmark.
Fill the intended package early. A roll-on ball, liner, seal, valve or soft-solid component can alter water loss, fragrance loss, corrosion, flow and consumer payoff. Store packages upright, inverted and on their side where relevant, then measure leakage, torque, ball movement, dose delivery and residue around the closure. Approve the emulsifier only when formula and package remain inside the same acceptance window.
- Ambient, heat, cold and temperature-cycle storage
- Viscosity, phase separation, droplet change and active crystallization
- Light, odor, color and fragrance retention where relevant
- Upright, inverted and side package orientation
- Fill accuracy, roll-on payoff, leakage and component compatibility
Measure sensory, residue and application without overstating efficacy
Antiperspirant users notice drag, wetness during application, dry-down time, tack, powdery residue, white transfer and after-feel. Build a blinded comparison using a defined application mass and panel protocol. Add instrumental spread, friction, dry-down or residue imaging if the development team uses those methods. A grade that stabilizes the emulsion but leaves unacceptable tack or roll-on drag is not a commercial solution.
Keep sweat-reduction, deodorancy, skin tolerance and claim support in the finished-product program. An emulsifier can influence active delivery and formula uniformity, but raw-material selection alone does not prove clinical efficacy or safety. Confirm preservative efficacy, microbiological quality, compatibility with shaved or sensitive skin testing protocols, and any regional notification or monograph requirements through qualified teams.
- Glide, wet feel, dry-down, tack and after-feel
- White residue, fabric transfer and package-area buildup
- Dose uniformity and active distribution in the filled package
- Finished-product efficacy, tolerance and claim substantiation
Qualify supply, documents and total formulation cost
Move from laboratory sample to pilot batch and first commercial lot against the same formula, process and test plan. Confirm that the sampled and quoted material share the same grade, active basis, carrier, manufacturing site and commercial specification. Request TDS, SDS, COA, allergen or animal-origin statements where required, restricted-substance declarations, package, storage, shelf life, minimum order, production lead time and annual capacity.
Compare cost per accepted kilogram of finished antiperspirant rather than emulsifier price alone. Include active content, practical use level, mixing time, energy, heating or cooling, batch yield, rejected-batch risk, fill speed, package performance, freight and inventory. A cold-process route can save energy but only if viscosity, stability and filling are robust. A lower-dose grade can still cost more if it narrows the process window or requires expensive oil-phase changes.
Send a complete antiperspirant emulsifier sample and bulk RFQ
Use the Juyou inquiry form to send the product format, active salt and solution concentration, internal water-phase percentage, silicone and organic oil blend, fragrance, powders, target viscosity, cold or hot process, package, stability climate, annual demand and destination. State whether the project is a new formula, an emulsifier replacement, a cold-process conversion, a residue improvement or a second-source qualification.
Ask for JY-R1290-1 and JY-R1230 sample recommendations, current TDS and SDS, sample COAs, proposed commercial limits, use-level starting points, processing guidance, sample quantity, lead time and quotation. Review the broader Personal Care Silicone Materials category if the project also needs a matched fluid, elastomer or film former. A complete brief helps technical and purchasing teams test the same formulation objective.

Frequently Asked Questions
What is the difference between water-in-silicone and water-in-oil antiperspirant systems?
Both place an aqueous internal phase inside a continuous oil phase, but a water-in-silicone system uses silicone as a major part of that external phase. Mixed silicone and organic oils are also possible. The emulsifier must be qualified in the exact external-phase blend and active-salt load.
Can JY-R1290-1 handle a high internal water phase?
The published profile positions JY-R1290-1 for high internal aqueous phase W/O or W/Si systems, but the achievable level depends on active salts, oils, fragrance, process and package. Confirm it through a controlled phase-ratio and stability ladder.
Does cold-process suitability guarantee a stable antiperspirant?
No. Cold processing is a useful route, but addition order, shear, temperature, active solution, oil blend and package still control stability. Validate laboratory, pilot and first commercial batches against the same acceptance plan.
Does the silicone emulsifier determine antiperspirant efficacy?
It can influence emulsion uniformity, delivery and sensory behavior, but efficacy is a finished-product outcome. Active level, package dose, application, stability and the required regional clinical or monograph testing must support any claim.
What should an antiperspirant silicone-emulsifier RFQ include?
Include format, active identity and concentration, internal phase, silicone and organic oils, fragrance, powders, target viscosity, process, package, stability climate, required documents, annual demand, destination and qualification schedule.
