Feminine wash OEM/ODM manufacturing
Feminine Wash · Intimate Wash · OEM/ODM
A feminine wash is a daily-use product for one of the most sensitive areas of skin on the body. The skin of the external intimate area is thin and has a slightly more acidic pH than skin elsewhere, so ordinary cleansers can easily cause dryness and imbalance. A good product cleanses gently, keeps a mildly acidic pH with lactic acid, has a very light scent or none at all, and is for external use only — not for internal douching. Betel leaf is a familiar story for Vietnamese consumers, while aloe vera and chamomile bring a soothing feel. This category is also especially prone to advertising that goes beyond the cosmetic scope, so label wording needs tight control. Butter-C offers full-service OEM/ODM manufacturing, from formula to a finished, labeled product with its cosmetic product notification.
Formula base
A gentle cleansing system at a mildly acidic pH
A feminine wash consists of gentle cleansers at low concentration, a lactic acid buffer to hold the pH, and soothing ingredients.
Cleansers
Glucosides, betaines, amphoacetates — gentle cleansing with moderate foam.
pH buffer
Lactic acid and sodium lactate keep the pH mildly acidic, close to the natural pH of this skin area.
Soothing agents
Aloe vera, chamomile, panthenol, allantoin.
Featured ingredients
Betel leaf, fermented probiotics, licorice — a blend of traditional and modern stories.
Key technical points
Four factors that define feminine wash quality
Stable pH
The lactic buffer keeps the pH within the agreed range throughout shelf life; pH is measured after aging.
Gentle on sensitive skin
Low total surfactant, no SLS, limited fragrance and essential oils.
Preservation at acidic pH
Preservatives selected to work well at acidic pH, used at low levels, with microbial challenge testing.
Clear directions for use
The label clearly states external use only, no internal douching, and a sensible frequency of use.
Three formulation directions
Three common feminine wash lines
Traditional betel leaf
Betel leaf extract with a light green tint; a story familiar to Vietnamese consumers.
Gentle daily care
Aloe vera, chamomile, fragrance-free; suited to daily use and sensitive skin.
Fermented probiotics
Lactobacillus ferment filtrate and inulin; a modern balance story.
Packaging is designed together with the formula
Pump bottles, foaming bottles, small travel sachets; discreet design.
Parameters we monitor
What our R&D lab measures on every sample
Below are the parameters Butter-C monitors during formula development and scale-up to production. Specific limits are agreed with you on the approved sample and then written into the product's in-house specification.
- pH
- Measured when freshly made and after aging; the key parameter.
- Viscosity
- Checked across temperatures so the pump dispenses evenly.
- Lactic acid content
- Per formula, to maintain buffering capacity.
- Microbiology
- Tested at a GLP / ISO 17025-accredited laboratory.
- Preservative efficacy
- Preservative efficacy (challenge) test on the final formula.
- Color and odor
- Stable after aging; betel leaf extract tends to darken.
- Packaging compatibility
- Monitored for pump performance and leakage.
Claims
Writing claims within the cosmetic scope
